When applied to the procurement of electronics for the U.S. Military, COTS is a procurement philosophy and does not imply commercial, office environment or any other durability grade. E.g., rad-hard components designed and offered for sale to the general market are COTS if they were developed by the company and not under government funding.

Inside Track Army Releases Small Unmanned Ground Vehicles (SUGV) for Operational Use The U.S. Army’s TACOM Life Cycle Management Command has approved the Conditional Material Release for forty-eight XM1216 Small Unmanned Ground Vehicles (Figure 1). The systems were distributed to the 3rd Brigade, 1st Armored Division, and the U.S. Army Infantry School. The Material Release process assures that Army materiel is safe for the Warfighter, suitable to meet operational performance requirements, and supportable within the environment it is intended to operate. The SUGV is a lightweight, portable robotic system designed to aid the dismounted Warfighter or Infantryman in the performance of urban intelligence, surveillance and reconnaissance missions, and assist with providing situational awareness/understanding. The Soldier or Marine sends commands to the SUGV from a handheld controller and receives information through live and still imagery. The SUGV can investigate buildings, vehicles, tunnels, sewers, caves or personnel to seek out potential threats. Weighing 32 pounds, the SUGV is designed to be transported in a standard Modular Lightweight Load-carrying Equipment (MOLLE) backpack. The SUGV program is managed by RS JPO, under the direction of the U.S. Army’s Program Executive Office Ground Combat Systems.

Function-Specific vs. General Purpose Pre-Integrated Systems

Special Feature

Function-Specific Integrated Systems Get Closer to End Application While not replacing military systems’ end functionality completely, a slew of new function-specific system offerings are providing significant time and cost savings for military system developers. Jeff Child, Editor-in-Chief


n parallel with the trend toward rugged box-level systems is another trend toward “pre-integrated subsystems.” These are defined as a set of embedded computing and I/O boards put together and delivered as a working system to provide a certain function, but intended to be used in a military customer’s larger system. Some of these are function-specific, whereas others are more generic computing/networking platforms. The emergence of the function-specific type of system doesn’t mean that the more general-purpose approach is going away. Most vendors that offer function-specific offerings also continue to develop a robust set of general-purpose pre-integrated systems. Driving the function-specific system demand is the trend among prime contractors to an ever greater reliance on embedded computing suppliers. They’re asking for integration expertise and a level of software development as part of those integration efforts. This is driven in part by the need for primes to contain their costs. And that’s expected to continue as more and more military programs are structured as fixed-price rather than cost-plus.

New DoD Policies Drive Trend Also driving this trend are DoD procurement policies that drive increased interest in preconfigured subsystems from COTS vendors. These new policies demand more demonstration of new technologies. The policy also pushes for demonstrations earlier in the program development phase. Technologies also used to July 2011 COTS Journal [ 11 ]

An early example of function-specific integrated systems was the SMU (Sensor Management Unit) subsystem deployed aboard the Global Hawk UAV. The SMU works essentially as an interface fusion box, routing various interfaces and fusing them together.

have to show higher technology readiness levels (TRLs) than previously required. The result is ever greater demand for prepackaged and prequalified subsystems as primes find themselves without the time or the DoD funding to develop a prototype subsystem internally. One of the earliest examples of this function-specific integrated system trend was Curtiss-Wright’s SMU (Sensor Management Unit) subsystem. Deployed aboard the Global Hawk UAV (Figure 1), the unit offers the capability to support Gbit Ethernet and High-Speed Fibre Channel links while interfacing with legacy interfaces such as 1553, RS-422, ECL and Fast Ethernet. In this way, the SMU works essentially as an interface fusion box, routing various interfaces and fusing them together. The SMU’s fully ruggedized aluminum chassis evolved from the original version (used in Global Hawk Block 20), adding significant capacity for

system expansion (planned for BAMS Global Hawk) while addressing demanding environmental requirements.

Need for Scalability Helping to drive this evolution has been an increased demand for modularity and scalability. UAV system integrators are being called on to enable both scaling up and scaling down of particular subsystems as required by the mission and payload configuration of other UAV platforms. This trend has driven designs to use VPX-based I/O-centric processors with multiple and widely supported highspeed fabric I/O interfaces and expandable high-bandwidth memory. The current Network Centric Mission Management Computer (Figure 2) is a 6U 21-slot system with Serial RapidIO mesh, VPX-conduction-cooled solution. It integrates 6U SBCs with 6-port Dual Redundant MIL-STD-1553 Interface

DSP-Centric System Another twist on the function-

specific approach is to tailor the system for a particular kind of technology such as digital signal processing (DSP). With that in mind, Kontron offers a system designed for the needs of compute-intensive DSP-based systems. The Kontron HPEC platform (Figure 3) is a VPX-based super computer-like system that accommodates up to 18 Kontron 6U VPX VX6060s, powered by Dual Intel Core i7 processor computing nodes, and employs 36 tightly coupled processors. Using its VXFabric technology, the

system uses a simplified API that allows high-speed socket-based communication between blades by using multiple switched fabric interconnects within the backplane. The 72 core, 18-blade Kontron HPEC platform provides a breakthrough in compute density, up to 1.44 Teraflops (1.44 Trillion Floating Point Operation per second) in a small 19-inch footprint that delivers the high-performance computing power that is a critical capability for many of today’s military systems.

New designs of pre-integrated subsystems must consider the CPU-intensive applications required by UAV control systems. products based on modular PC/104 standards. With this broad base of PC/104compatible options, modularity for preintegrated subsystems is optimal. As an example, one manufacturer of a military tilt-rotary aircraft (Figure 1) specifies the multicore version of the DuraCOR pre-integrated subsystem with COTS PC104+ modules supporting MILSTD-1553 avionics bus interfaces and MPEG video encoding. The prime contractor leverages the unit to provide platform mission processing, among other capabilities. In a recent quick-reaction capability (QRC) demonstration for the U.S. Government, the DuraCOR unit was repurposed to link with a stand-alone Ethernet switch subsystem to expand the aircraft’s situational awareness capabilities by sharing and receiving real-time video feeds with ground commanders. To further reduce size, weight and power (SWaP), the customer is looking at also integrating the Ethernet switch (also based on PC104 architecture) into an open card slot within the DuraCOR computer housing, eliminating the need for separate computer/switch boxes. As this customer demonstrates, the flexibility [ 20 ] COTS Journal July 2011

of pre-integrated subsystems allows this computing platform to perform a variety of functions for various applications.

Debating Power vs. Performance In today’s military platforms, reducing a system’s size, weight and power (SWaP) is critical for operational life and budgetary constraints. The number of electronic payloads within the military’s combat vehicles has increased significantly, and designers of pre-integrated subsystems must include greater embedded processing power while trying to mitigate large power consumption. Plus, the growing need for mobility eliminates the option to increase the footprint to make room for more power or more performance. As a result, multicore processing technology is experiencing a significant boost in deployment within preintegrated subsystems. While previous multiprocessing solutions involved one or more physical chips, which doubled he amount of board space consumed or more, the introduction of multiple processing cores in a single chip allows operating systems and applications to leverage

increased computing power. It also has provided access to additional computing resources without noticeably increasing the size or weight of the system. For demanding applications, mobile Core 2 Duo or Core i7 processors, as examples, provide attractive solutions. While presenting a challenge to manage the 10-55 watts of thermal design power (TDP) of these processors, they offer a level of performance that pushes the boundaries of traditional rugged computing required by new applications. With the high level of performance offered by multicore processors, high power requirements become an issue. Low-power options such as Intel’s new Atom processor family inject more possibilities for rugged stand-alone boxes. This low-power processor has a thermal design power (TDP) specification in the 0.6-2.5 watt range and scales to 1.8 GHz speeds depending on customer need. By comparison, today’s mainstream mobile Core 2 Duo processors have a TDP in the 17-35 watt range. New multicore Atombased single board computers (SBCs) are also entering the scene, which promises the best of both scenarios with lower

power consumption than the Core 2 Duo yet better performance metrics compared to legacy single core Atom processors. Atom-based solutions, however, don’t typically support the PCI Express Graphics (PEG) bus for certain graphics-intensive applications.

Need for Prompt, Fresh Designs To bridge the divide between power vs. performance, suppliers of pre-integrated subsystems are engineering solutions that offer some middle ground. For its part, Parvus is designing new Intelbased pre-integrated subsystems that provide greater performance while still maintaining power efficiency. To support the military’s escalating Intelligence, Surveillance and Reconnaissance (ISR) efforts, which include compute-intensive applications such as sonar, radar, SIGINT and UAV control systems (Figure 2), these new subsystems will include PCI Express capabilities to support higher speed addon cards for graphics, SATA, video and other removable media. As with any computing system designed for the military, new products continue to focus on minimizing size and weight. Some traditional limitations for pre-integrated subsystems have been providing a COTS design that supports the right number of cards, enough connector interfaces and sufficient thermal and shock/vibration ruggedization—all while being optimized to meet military customer requirements. Taking a cue from the “Lego-like” stacking architecture of PC/104, the mechanical design for Parvus’ next-generation subsystems aims to overcome these hurdles and maximize flexibility of a rugged COTS subsystem. The approach incorporates a modular rugged enclosure with building block chassis segments that have pre-integrated card sets, along with MIL connector interfaces and optimized thermal management devices. Depending on customer requirements, a particular functional card set can be configured for stand-alone use—for instance as a computer, router, or Ethernet switch—or attached to each other and consolidated within a single, compact mechanical solution. Compared to the traditional ap-

The operating system used in pre-integrated subsystems is dictated by the application’s requirements. Vehicle needs are very different than aircraft needs for example. Pre-integrated subsystems are designed to accommodate the many varieties of operating systems currently available. proach of working around a fixed-sized box with a pre-defined number of open card slots, this modular approach provides greater flexibility, superior technology reuse and provisions for mechanical adaptations.

Application Engineering Fills the Void The ability for customers to optimize COTS subsystems is a key motivator for the further adoption of this technology as it reduces costs and speeds time to deployment as compared to custom designs. However, many companies are facing human resource constraints or aggressive project schedules that restrict their engineering groups from modifying products in-house. Application engineering groups at Original Equipment Manufacturers (OEMs) fill this void by assisting system integrators with application-optimized, turnkey solutions that reduce development time while increasing customer interface and feedback, ultimately lowering the costs of modifications and the risk associated with third-party subsystem integration.

Subsystem integration services, also called application engineering, are becoming increasingly popular as customers witness the cost benefits of leveraging qualified COTS subsystem platforms. Application engineering teams quickly become experts at understanding requirements and proposing the most rugged yet cost-effective approach to meet their program’s functional and environmental requirements. Common requests of Parvus application engineers include the integration of application-specific boards, loading of custom operating systems, upgrading of memory/mass storage devices, and handling mechanical, connector or interface customizations. Application engineers provide accessibility between design engineers and customers to ensure their integrated subsystem will meet user demands and provide the best deployment possible. Since these engineers often serve as the technical point of contact when optimizing systems, communication between the manufacturer’s resources and the customer is greatly improved. This communication not only ensures that customers’ expecJuly 2011 COTS Journal [ 21 ]

Customizing OS for Mil Applications Among the many variables that comprise pre-integrated subsystems is the Operating System (OS). The open architecture of pre-integrated systems is hugely beneficial to military customers as they can choose the OS that works best for a particular application (Figure 3). Military customers have a diverse set of OS preferences varying from “roll your own Linux” to commercial Windows OS depending on the customer’s unique application and requirements. Real Time Operating Systems (RTOSs) are proving to be particularly popular among aerospace programs that demand application-specific tasks be executed reliably, consistently and pre[ 22 ] COTS Journal July 2011

dictably. This is especially true in terms of flight software and complying with avionics certification standards such as DO-178B and its follow-on standard DO178C. The ability of an RTOS to boot up within nanoseconds and respond quickly to events is proving critical to mil-aero applications where each second can translate into saved lives. The influx of multicore processors in pre-integrated subsystems has also spurred RTOS offerings to include technologies and capabilities to take advantage of the performance gains of multicores. For example, Wind River’s VxWorks 653 now supports multicore architectures that will allow the addition of more applications to a single platform. To maximize the performance of pre-integrated subsystems, the OS needs to be optimized to contain just the functionalities required by the application without any unnecessary features. As added complexities of an OS can con-

An example product that’s part of this pre-integrated systems trend is the DuraCOR 810 (Figure 4) rugged computer offered by Parvus. It includes up to six spare slots and a large spare DTL-38999 expansion connector conveniently routed to an internal breakout board and headers. This allows for application-specific PC/104(+) cards to be integrated without having to make external mechanical changes. For this reason, customers are not only interested in these rugged boxes as stand-alone computers, but also as an upgradeable computing platform. Military applications present engineers of pre-integrated subsystems with some of the most intense design challenges in the COTS world. Not only do modern military customers demand that pre-integrated subsystems withstand extreme conditions, but they must reduce SWaP—all without sacrificing performance. As the military continues to push the limits of computing system requirements, pre-integrated subsystems will continue to evolve to endure the toughest conditions. Parvus Salt Lake City, UT.

Networked-Military Calls for More Complex UPS and Power Distribution Tech In this era of mission-critical networked systems, uninterruptible power supply technology and power distribution are moving to center stage.

apoleon once stated that “an army travels on its stomach.” Today’s new high-tech military travels on its communications capabilities. The spectrum of these capabilities encompasses the entire radio frequency (RF) spectrum, from wired and wireless land-based digital systems to proprietary satellite data networks. These systems include radios, computers, servers, telco systems and every network device imaginable. Every facet of the military depends on these critical communications and data systems. Since the digital revolution of the 80s and 90s, the military budget for these systems has exploded. Further, the large availability of low-cost off-the-shelf network infrastructure products has allowed the military to keep the cost of the systems at a minimum, while maximizing their effectiveness. When it comes to communications networks, the U.S. military operates and maintains one of the largest networks on earth. The diversity of their network is becoming mind-bending. While one facet of the network supports the remote con-

It can display maps and images from the weapon-mounted camera. A mouse-type control is also part of the weapon, allowing the soldier to toggle between screens on his video display. The system further supports weapon aiming, a laser range finder, night vision

and multiband radio capabilities. The soldier’s personal network can be connected to a transceiver that can connect to a local area network and other soldiers, or in some cases can be connected to a satellite network. The amount of distributed network infrastructure required to support the Land Warrior System alone is massive. Network support elements can be land, air, sea or satellite-based.

It takes a massive amount of distributed networking and computer hardware to support such a monstrous network, and the military looks at the commercial market for its procurement whenever possible. The low cost and fast delivery of off-the-shelf equipment is preferred over proprietary solutions. When commercial equipment is selected for use, there are some considerations that must be made prior to its deployment.

Temperature Issues Of primary concern is that most off-the-shelf network products are designed to be installed and operated in a temperature-controlled and protected office environment. In a large military base located in Europe or the U.S., this usage would be perfectly acceptable providing it was installed indoors and powered from a local utility source. However, should the equipment be part of a system that can be deployed anywhere in the world, this may not be the case. Environment and power could result in the equipment’s unreliable operation or its failure. As an example, should the base be located in a third-world country and powered from a questionable local utility or generator source, there is a good chance the equipment operation will be compromised. The addition of a high-grade on-line uninterruptible power supply (UPS) would have to be configured in the system to clean up power problems and supply power during periods of utility power loss and generator startup. Should the base be located in a desert region or the Middle East, where temperatures can reach 120° to 130°F, further considerations must be made. Most commercial computer, server, networking and UPS equipment is designed to operate in a temperature range of 32° to 104°F (0° to 40°C). The Uptime Institute, a leading data center authority, states that for every 18 degrees Fahrenheit increase in temperature above 70 degrees Fahrenheit, the long-term reliability of data center equipment is reduced by 50%. In these locations, to ensure reliability, computer, network and power conditioning equipment must be rated for wide temperature operation. 1 [ 26Untitled-11 ] COTS Journal July 2011

Wider Temp Ranges Since the military has been deployed in the Middle East for over 10 years, the demand for equipment rated for operation over a wider temperature range has increased. The demand for network infrastructure and UPS power conversion products rated for operation in higher temperature environments has not gone unnoticed by some equipment manufacturers. The market demand has been

increased even further as many non-military industrial applications have the same operational temperature requirements. This is driving more and more network, computer and UPS manufacturers to address the demand. This is resulting in new families of products specifically designed to operate reliably over a wider -4째 to 131째F (-20째 to 55째C) temperature range. Figure 2 shows an example product from Falcon Electric along those lines.

Due to the extreme levels of vibration and shock present in some military applications and tied with the requirement for a wide operational temperature specification, most commercial-grade equipment is prevented from being used as is. However, many manufacturers are finding that the commercial-grade circuit board level electronics may be repackaged into a new more protective enclosure. Thermal concerns are addressed with the addition of thermal management devices.

Power Distribution Moreover, often due to the large amount of commercial-grade server, networking and communications equipment that must be plugged in and powered at a given location, power distribution is a perpetual challenge. Most installations use one or more power distribution units (PDUs) to feed power to each device in the system. The power connector styles of each piece of equipment in the system can vary with some using commercial styles and some using MIL-STD styles. Additionally, the required power configuration for each piece of equipment can vary from numerous AC configurations to various DC voltages. Figure 3 shows an example PDU product from Marway Power Solutions. Since the PDU is a common point at which this equipment is tied together, it can be beneficial to resolve these challenges in the PDU itself. This can be done by using a modified commercial-grade PDU to help integrate the various connector styles and power configurations required by the equipment. The PDU itself can be configured to provide the appropriate mating connectors for each piece of equipment, thus avoiding the need for adapter cables. If DC power is required for some equipment, the PDU can also be configured with an internal power supply, thus eliminating the need for external power supplies. Both of these approaches help to simplify the overall system.

Design Complications Of course the environmental concerns present for the other equipment in the system also apply to the PDU. In many [ 28Untitled-4 ] COTS1Journal July 2011

The SSG is ideal for harsh military power environments. cases commercial-grade components used within the PDU are analyzed and repackaged or replaced to add extended capability to meet adverse temperature, shock and vibration requirements for the target installation. Other applications such as ground transport, airborne, submarine and shipboard further complicate design considerations. These environments can be conducive to salt spray, EMI, humidity, sand blasts, icing and freezing rain, which can further impact the enclosure design

as well as internal component selection. In many cases traditional electromechanical control devices used in commercial-grade PDUs cannot meet the criteria and thus the need for solid state technology becomes more appropriate. However, these devices carry the challenge of managing additional thermal dissipation, which can drive unique airflow requirements. Other features are often desirable to help simplify the design, installation and maintenance of the overall power system.

Depending on the installation location and available power quality, additional power conditioning may be required in the PDU itself. This can include transient voltage suppression through the use of a surge protection device (SPD). It can also include power line noise suppression through the use of an EMI filter. In multi-phase applications it is helpful for the PDU to include some local monitoring capability to allow efficient installation without the need for user-provided power measurement tools. A local monitor can provide input current values for each phase providing an easy means to ensure the entire system is balanced during setup. Despite the increasing desire for value-added features inside the PDU, it is important to recognize that space is always at a premium. As the high-tech military continues to expand its capability, suppliers of network and power conditioning products are faced with challenges to minimize footprint, reduce weight and increase capacity.

curity analysts to concentrate their efforts on ensuring the robustness of the at-risk attack targets. The result is that they are able to substantially improve the security of the code with reduced resources. Today virtually every military software application connects to a network and an increasing number connect to the Internet. So what used to be external in-

terfaces are now potential points of attack. Microsoft, Carnegie Mellon University and others pushed forward the concept of the attack surface for identifying areas of potential vulnerability. SSA provides a method of identifying the attack surfaces, which encompasses code, interfaces, services and protocols. From the standpoint of code analy-

sis, a significant concern consists of areas where the system obtains external input, such as functions that accept data or read configuration files, environmental variables or registry entries that affect application behavior. Malicious attacks often originate from these entry points, so it is important to review them to assess their correctness and robustness. But todayâ&#x20AC;&#x2122;s software can also have hundreds of potential attack targets inside the application, and there is rarely if ever enough time available to thoroughly check them all out. SSA typically ends when the team runs out of time, money or finds a specified number of bugs. Path-based methods enable an approach that much more effectively leverages the available SSA resources. The attack targets are analyzed based on their connections to attack surfaces through call relationships. The value of this approach is that a large proportion of attack targets does not interact with attack surfaces, and therefore is completely benign. The identification of these trivial attack targets makes it possible for security analysts to focus their energies on the typically small proportion of attack targets that present a real danger.

Identifying the Critical Paths The critical areas of code requiring analysis for potential security remediation are identified through the creation of an attack map that links attack surfaces to attack targets. The creation of the attack map begins with the identification of functions that characterize the attack surfaces and attack targets. For example, create a set called AttackSurface and add to its contents the functions from the input space that you wish to trace. In a network application, the recv() function, which receives data from a socket, may be of interest. Next, create a set called AttackTarget and specify target functions that identify critical areas of the code. An attack map (Figure 1) is created by requesting the tool to provide a reduced view, consisting only of functions in the attack surface set, the attack target set, and the functions that link them through call relationships. All other functions will [ 34Untitled-9 ] COTS1Journal July 2011

be filtered from view. Further analysis and reporting can proceed from this focused view. The attack map clearly identifies the functions and paths that are potentially exercised in the execution flow of an attack, and therefore should be carefully analyzed and tested. Less attention needs to be paid to functions that are filtered out. This approach can substantially improve the security of an application by enabling security analysts to focus their attention on areas of code that could potentially be utilized in an attack.

Securing the Critical Paths The paths of execution control identified on the attack map are potentially critical to application security, and therefore should be carefully analyzed and tested using a path-based approach. A program metrics report can be produced to show the program integration complexity for the subset of functions of interest. The program integration complexity represents the number of unique, linearly independent paths exercising all calls through the functions shown in the chart. This can be used to help estimate the effort of further analysis. A metrics report (Figure 2) helps determine which functions of an attack map or subset have a high risk due to their complexity. The report in Figure 2 shows that one of the functions in this rooted subset of the attack map has a cyclomatic complexity (v(G)) greater than 15. Refactoring could be used to break down complex functions in the attack map into smaller functions, many of which will likely be outside the attack path of execution, reducing the security risk. The next step is investigating each root level function and examining the integration paths that reach the attack target. The structure chart (Figure 3) shows a hierarchical call tree of functions. Alternatively, a chart showing class relationships can be displayed. To focus analysis on an individual call tree, filter the structure chart to show only the functions in a call tree rooted at the specified function.

This report shows functions in an attack map, including their cyclomatic complexity.

Figure 3

This structure chart rooted at a function shows calls exercised for each call tree sequence.

Visualizing the Data Specific control flow paths can be analyzed by highlighting them, and by displaying the sequences of decision outcomes needed to exercise them thoroughly. The structure chart can show the linearly independent integration paths through the functions in the current chart. The user can step through the vari-

ous subtrees and the chart will highlight lines connecting the boxes that represent the calls exercised for the selected call tree sequence. Special attention should be paid to integration subtrees that highlight calls to both the attack target and attack surface. The chart can also be used to generate a test report on any design subtree listing the calling and called func-

tions and the test conditions needed to exercise the subtree. For further code and path analysis, drill down into the details of a function by right-clicking on a box on the structure chart or on a function name in a report, to bring up a context menu for selection. Selectable details include a graphical representation of the functionâ&#x20AC;&#x2122;s control flow and the source code for the function. The user can also step through sets of integration of cyclomatic paths through the function. The flowgraph, annotated source coding listing and test path details can be used to carry out a thorough analysis of each function in the attack map to ensure the control flow paths shown are valid, consistent with requirements and secure. Path-based code coverage analysis should also be applied to all code in an attack map, to further reduce your security risk. At a minimum, testing should be required through all integration paths in an attack map; that is, with a goal of 100% integration path coverage, with exceptions only where certain path combinations cannot be attained. If resources permit, it is suggested to apply code coverage analysis at the cyclomatic path level for functions in an attack map.

Reduced Security Risk The path-based methods described here can make a substantial improvement to SSA by identifying potential vulnerable code based on linkages between attack surfaces and attack targets. Pathbased methods can also be used to assist in securing the critical paths by providing a methodical approach to analyzing integration paths linking attack surfaces and attack targets. The end result is an improvement in military application security while working within the existing SSA resources. McCabe Software Cranston, RI. (401) 572-3100. [].

CWE Initiative Helps Secure Code Development Efforts With cyber threats a new part of today’s military landscape, the Common Weakness Enumeration standard is helping to shape and mature the code security assessment industry. Deepu Chandran, Field Applications Engineer LDRA Technology


hroughout the developed world, governments, defense industries and companies in various sectors are increasingly targeted by cyber attacks seeking economic or military advantage. The number of attacks is now so large and their sophistication so great that many organizations have trouble determining which new threats and vulnerabilities pose the greatest risk and how resources should be allocated to ensure that the most probable and damaging attacks are dealt with first (Figure 1). In August 2003, a rolling blackout affected 10 million people in the Canadian province of Ontario and 45 million people in eight U.S. states, raising concern of a cyber attack. Although the causes of the blackout traced to a slew of system, procedural and human errors and not an act of aggression, the event brought home the vulnerability of critical infrastructures that had become dependent on Internet communication for control and monitoring. This event helped raise awareness of the need for secure system components that are immune to cyber attack.

An Entrenched Problem Software security exploits have existed for years, with the first documented Internet virus appearing in 1971. In 1988, the Morris worm brought 10 percent of Internet systems to a halt, infecting Internet-connected DEC VAX and Sun ma[ 38 ] COTS Journal July 2011

It became the first worm to spread extensively “in the wild” and was one of the first programs to exploit buffer overrun vulnerabilities. Given that software and connectivity are now integral to many critical and noncritical applications, organizations want assurance that the software products they acquire and develop are free of known types of security flaws. With that in mind, it’s helpful to look specifically at the best practices and knowledge for building secure software

that is free from vulnerabilities.

Enter the CWE Standard One of the security initiatives gaining momentum is the CWE standard. CWE, the Common Weakness and Enumeration database, is a project that incorporates an international community-developed formal list of common software weaknesses developed from an all-inclusive database recording all exploits and vulnerabilities captured over a number of years. CWE is a software assur-

Tech Recon ance strategic initiative maintaining a database of security vulnerabilities by the MITRE Corporation under a Federal grant and cosponsored by the National Cyber Security Division of the U.S. Department of Homeland Security. The CWE effort aims to help shape and mature the code security assessment industry and to dramatically accelerate the use and utility of software assurance capabilities for organizations in reviewing the software systems they acquire or develop. According to research directed by the National Institute of Security Technology, 64 percent of software vulnerabilities stem from programming errors. To help identify core weaknesses contributing to software vulnerabilities, MITRE Corporation, a public interest not-for-profit organization, created the CWE list. MITRE manages several federally funded research and development centers, including one for the Department of Homeland Security that is mandated with developing the CWE project. CWE was created to address the concerns of organizations that want assurance that the software products they acquire and develop are free from known types of programming errors.

Common Vulnerabilities and Exposures The MITRE Corporation has been involved in the area of software security for many years, including the creation and maintenance of the Common Vulnerabilities and Exposures (CVE) database. Created before CWE, the CVE database is a repository of security exploits that have been identified, whether the exploit was identified in a laboratory or â&#x20AC;&#x153;in the wildâ&#x20AC;?â&#x20AC;&#x201D;meaning an attack that occurred before the vulnerability was known about. After the CVE database had been in existence for a while, the MITRE Corporation analyzed the documented vulnerabilities and exploits and identified the core weaknesses that made the exploits possible. The result is the CWE database, a repository of the core security weaknesses that have led to exploitable security vulnerabilities. CWE targets developers and security practitioners, offering a common language for describing software security weaknesses in architecture, design, or code and serving as a standard measuring

stick for software security tools targeting these weaknesses. It provides a common baseline standard for weakness identification, mitigation and prevention efforts.

How CWE Is Structured The organizational structure of the CWE elements is defined for leveraging by various audiences and for various purposes through the use of axonometric layering where the errors are grouped according to categorical similarities. It has been described as a three-tiered approach from all axis, in which: (1) the lowest level consists of the full CWE List (hundreds of nodes), which is primarily applicable to tool vendors and detailed research efforts; (2) a middle tier consists of descriptive affinity groupings of individual CWEs (2550 nodes), useful to software security and software development practitioners; and (3) a more easily understood top level consisting of high-level groupings of the middle-tier nodes (5-10 nodes) to define strategic classes of vulnerabilities and which is useful for high-level discourse among software practitioners, business people,

System quality is affected by a number of metrics, including security. tool vendors, researchers and so on. Despite this high-level outline, there is no formal structure to the CWE database; each weakness is added to the database as it is discovered. And the database is maintained in XML format, so there are a number of filters that can be applied to review the results. This can either be done on the CWE website (, or by downloading the full CWE XML file and applying filters locally. Note that the content and format of the CWE database is under constant review to help maintain the accuracy and relevance of the data. One of the latest initiatives adds qualifying data to each entry that paints a picture of how a weakness appears in the field and how it could be exploited. The CWE database is an all-inclusive database that encapsulates all security weaknesses that have been proven to lead to exploitable vulnerabilities. These weaknesses could be at the infrastructure levelâ&#x20AC;&#x201D;such as a poorly configured network and/or security applianceâ&#x20AC;&#x201D;, policy and procedure level (sharing usernames and/or passwords) or coding level. For the coding level, all of the software languages that are associated with contemporary enterprise deployments are considered, including but not limited to C, C++, C#, Java and PHP. What the CWE database does not do is capture known coding weaknesses that have NOT been traced to an exploitable weakness.

Securityrelated issues are at the forefront of decision making for military and aerospace systems development. Software developed for the defense market often requires systems to mitigate the risk of one component of the software affecting another. To fulfill these contracts, customers must demonstrate how they have achieved a minimum level of software security, and CWE compliance is one means of doing this. To do this, developers need a tool that is CWE compliant, such as the LDRA tool suite, which is the key to demonstrate and document how the software under development has met a minimum security requirement. Other security standards such as the CERT-C secure coding rules complement this objective, extending the security characteristics of an application even further.

Writing Secure Software The only way to write secure software is to build security in. Typically, the sources of vulnerability rise from coding errors, configuration errors, architecture or design flaws. Developers or programmers normally assess quality without considering security as a part of quality code. The functionality of the application is the focus for developers during development and

testing, but they ignore the fact that security also plays an important role in overall system quality. Security problems can occur even if complete functionality of the system is satisfied and even due to the occurrence of an unintended functionality. Figure 2 illustrates the metrics contributing to system quality. By focusing on these measures at all phases of the software development lifecycle, developers can help eliminate known weaknesses. A common understanding of the security goals and approaches to be taken during development within the team can contribute to eliminating these flaws. In approaching a secure programming focus, developers need to establish the risk assessment and secure coding practices.

Risk Assessment Risk Assessment evaluates the security risks associated with the software under development and determines the quantitative or qualitative value of a risk in relation to a concrete situation and recognized threat. The nature and impact of security breaches can be determined prior to deployment and helps to identify the security controls necessary to mitigate any identified impact, location, intensity and probability of a threat. Once risk is determined, the identified July 2011 COTS Journal [ 43 ]

Tech Recon security controls become part of the system’s requirements. By adding a security perspective to software requirements, the entire development process is affected. Translation of these requirements roll out into architecture design, coding, and are subsequently checked at analysis and testing phases. The capacity and resources available to address or manage threats is known from this assessment.

Secure Coding Practices An essential element of secure software development involves well docu-

mented and enforceable coding standards. Coding standards encourage programmers to follow a uniform set of rules and guidelines as established by the requirements of the project and organization, rather than by the programmer’s familiarity or preference. Once established, these standards can be used as a metric to evaluate source code (using manual or automated processes) to determine compliance with the standard. While CWE does not mandate an automated standard checker, secure coding practices do require both static and dy-

namic assurance measures. Using a static analysis plug-in that confirms CWE compatibility ensures that the rules checked for are consistently and systematically applied to the code. The dynamic analysis takes place on the target and provides assurance that errors that would only show up during execution are not present in the code. However to fully meet the software development and verification requirements, it is necessary to include traceability, static source code analysis, dynamic coverage, data flow, control flow analysis and testing facilities. Figure 3 illustrates how requirements traceability maps requirements to design specification, verification plan, verification reports and source code in LDRA’s TBreq. Such graphical representation makes it easy for developers to immediately spot such things as code that does not map to requirements, failed tests or code that lacks tests, which the software clearly flags.

By mapping CWE into requirements, developers have the option of taking advantage of tools that automate requirements traceability, which in turn manages the relationships between all components in the development lifecycle. The amount of time saved in manually tracing and verifying relationships is significant, cutting time costs and automatically documenting the development process for subsequent verification by standards organizations. As the implementation of standards like CWE becomes more widespread, a tool vendor’s experience and reputation in security- and safety-critical expertise will be invaluable. Use of qualified and well-integrated tools ensures that the developers can automate the process more easily and efficiently. Creating a secure development community using standards, technologies and a well-integrated development environment promotes a continuous process of improvement. And, a focus on secure development lifecycle principles and practices will result in the ongoing production of software systems that are more dependable, trustworthy and extensible.

PCI Express Bladed Server Exemplifying this trend is the TCS4500 industrial server from Trenton Technology. Trenton configures, integrates and validates this shallow-depth, high-performance computer with longlife processors installed on Trenton’s JXT6966 single board computer. The system features the BPC7041 PCI Express 2.0 backplane plus multiple storage options. The TCS4500 (Figure 2) enables faster system deployments in many diverse applications such as shipboard navigation and submarine communications. Up to four front-access, hot-swap 2.5-inch storage drives are provided. The shallowdepth design of the TCS4500 chassis plus the high-performance computing capability of the system’s SBC, backplane and storage options creates an industrial server platform that is ideal for spaceconstrained applications. Illustrating the compute density advantages of rackmount systems, the Kontron Industrial Silent Server KISS 4U KTC5520 has up to 12 processing cores designed with new 32 nm technology. The system allows formerly separate apps to be moved onto a single, cost-effective system. It is a highly robust and longterm available open standard platform, offering up to two dual Intel Xeon 5600 Series processors. It features an operating temperature range of 0° to 50°C, an operating humidity range of 10-95%, allaround IP 20 protection (optionally upgradeable to IP 52 at the front), and high shock and vibration protection, which makes the server perfect for applications where more ruggedized systems are necessary. The server board can be fully managed remotely. The Industrial Silent Server is available with up to two Intel Xeon (5500 or 5600) series processors and up to 48 Gbytes of DDR3 ECC registered SDRAM per processor. The server paves the way for a wide range of extensions, thanks to 1x PCI Express x16 (PEG) (configurable as 1x PCI Express x8), 3 PCIe 2.0 x8, 1 PCIe x4 (using x8 slot) and 1 x PCI.

Compact LAN-Based Solution Offering a line of 1U rackmount offerings, Win Enterprise features a series of LAN-connected units. Its latest is a 1U rackmount platform with the Intel Atom D510 dual-core or D410 single-core processor, including six GbE LAN ports and an externally accessible PCI slot. The PL80300 (Figure 3) provides externally accessible PCI card support for the D410 or D510 Atom Pineview low-voltage processors plus the Intel 82801HM Controller, external access to the PCI card slot and a maximum of six GbE LAN ports via PCIE x1. In addition, the unit includes USB 2.0, a 3.5-inch SATA HDD bay, CF socket, mini-PCI slot and Console port. ATCA has secured a solid niche in the military market, particularly for applications that stress high-performance communications and networking. By designing on ATCA-based systems, developers can deliver significantly lighter command and control stations that allow for improved mobility in the field. ATCA computer modules offer capabilities and processing power comparable to rackmount systems servers built on multicore server class processors. Because ATCA is a bladed architecture, multiple ATCA modules can be incorporated into a single chassis. Since the ATCA blades share a common enclosure, fan and power supply, they offer a simpler architecture that

OpenVPX Moves Forward as Second Wave of Products Hits As the second wave of OpenVPX SBC products rolls out, several vendors are joining the ranks of VPX providers. With VPX REDI ratified, the technology is moving closer to becoming the next dominant computer form factor for new military system designs.

power draw that requires more effective cooling strategies, and rugged and maintainable modules. VPX REDI targets the requirements of COTS platforms for defense and aerospace, defining mechanical design implementations for embedded computing modules. The following VPX REDI specifications have been ANSI/ VITA ratified: ANSI/VITA 48.0-2010: Ruggedized Enhanced Design Implementation Mechanical Base Specification; ANSI/VITA 48.1-2010: Mechanical Specification for Microcomputers Using Air Cooling Applied to VPX; ANSI/VITA 48.2-2010: Mechanical Specification for Microcomputers Using Conduction Cooling Applied to VPX; and ANSI/VITA 48.52010: Mechanical Specification Using Air Flow-through Cooling Applied to VPX. Companies that develop VPX products are encouraged to contact VITA to join the VPX Marketing Alliance. For more information, visit the VPX Marketing Alliance website at The ANSI/VITA48.x-2010 documents are available from VITA. The VPX standard was developed to define a new generation of computing systems that employs high-performance switch fabrics over a new high-speed connector, as well as operates in harsh environments. Which OpenVPX fabric to use will be dictated by the application area of the system. And on an architecture level, the fabric choice will be driven by how tightly or loosely coupled the processing and memory needs to be. For applications like radar (Figure 1) that require shared memory, RapidIO will be the data plane of choice. In contrast, if the system requires parallel processing—where very little data exchange is required between computing nodes—a fabric like PCI Express, Gbit Ethernet or 10 Gbit Ethernet is a better choice. For OpenVPX implementations that are distributed systems, PCI Express would be a natural fit depending on what size and what latency tolerances a system has. With PCI Express, each time you go through a switch or a bridge means more latency through the PCI hierarchy. That latency can be minimized using non-transparent PCI Express bridges or by “tunneling” through address spaces. Distributed processing is common in systems where size, weight and power are critical—like UAV flight controllers and other systems that have motors and distributed control nodes. In such systems computational density is important, but not to the level of high-performance computing.

It has provisions for the synchronization of multiple boards for capture and analysis of even wider bandwidths. Leveraging the National Semiconductor ADC12D1800 12-bit A/D converter, the 71640 provides two transformer-coupled RF input ports that can operate in single- or dual-channel mode. The 71640 also includes an onboard Xilinx Virtex-6 FPGA for customer-specific data processing. The module includes four banks of 256 Mbyte DDR3 SDRAM and built-in triggered data capture functions for acquiring precise data blocks. An optimized multichannel DMA engine provides efficient data movement over the Gen2 x8 PCIe interface to host processors. An optional 8x, or dual 4x, gigabit serial I/O interface allows users to support application-specific protocols and create high-bandwidth paths between modules or to additional signal processing engines. Pentek offers cPCI, PCIe, VPX and ruggedized, extended-temperature versions of the 71640. Radar and broadband communications signal acquisition are prime applications for the 71640. To capture wideband signals with previous-generation A/D modules, developers needed to split those signals into smaller overlapping bands and use multiple A/Ds to digitize those bands. This created challenges whenever the target signal fell in the overlap band. The 71640’s wide bandwidth now allows system designers to eliminate the pitfalls of such overlap processing while also saving system costs of the band-splitting filters and multiple data acquisition boards. For even wider bandwidths or for multichannel systems, the 71640 offers a synchronization bus that works with a companion timing module for sample-accurate synchronization of multiple Cobalt modules.

Coming Next Month Special Feature: VME, VPX and cPCI in Tech Upgrade Programs Among the reasons for VMEâ&#x20AC;&#x2122;s soaring success in military systems is its unique ability to remain backward compatible and facilitate technology refresh in military programs. A new board with the latest and greatest processor, memory and I/O can easily be dropped in to a slot that could be decades old. CompactPCI has followed in those same footsteps. But upgrades become trickier as new fabric-based VITA-standard boards enter the mix. Articles in this section examine the current activity in traditional VME and cPCI tech refresh along with the trade-offs involved in mixing those alongside newer VITA architectures like VXS and VPX. Tech Recon: Display and Computing Trends for UAV Ground Control UAV Ground Control systems represent a focal point of advanced display and computing technology. The systems need real-time performance and sophisticated video and graphics processing. Meanwhile the display subsystems in these systems need to display complex sets of real-time information. System architectures like ATCA and others have emerged as solutions for UAV Ground Control designs. This section compares the trends and products that meet the unique needs of these critical military systems. System Development: Military Data Acq Puts USB and PCI Express to Work Fading fast are the days when complex military electronics systems required large racks on boards to implement test platforms for them. Now the same test functions can be done on the PC using USB, PCI Express data acquisition and test modules. This section looks at the boards and software solutions driving this trend. Tech Focus: High-Density Storage Subsystems As military systems continue to rely more and more on compute- and data-intensive software, the storage subsystem is now a mission-critical piece of the puzzle. This section examines the emergence of Ethernet and IP-based storage interfaces, while comparing how traditional interface schemes like SATA, Fibre Channel and SCSI are positioned these days. Rotating drives still offer the best density, but flash-based solid-state disks F-SSDs are able to operate under the harshest conditions. This Tech Focus section updates readers on high-density storage systems and provides a product album of representative drives. [[ 64 64 ]] COTS COTS Journal Journal July 20112011

The Power of Joint Perspective


he regular habit of cost and schedule overruns is so entrenched in defense procurement that it’s hard to imagine a defense industry without those flaws. But to their credit, the government and DoD never fail to throw energy into improving the situation. As defense budget dollars tighten, the stakes get even higher and the DoD faces the prospect of doing more with less. With the reality of slowly growing or flat defense budgets for some years ahead, there’s great motivation to get better returns on its weapon system investments. An ability to make good trade-offs between cost, schedule and performance objectives at the time of developing and validating weapon system requirements will be important to achieving those returns. Some of that trade-off efficiency requires overseeing what’s possible between the military branches—bringing the power of “Joint” into the acquistion realm in a real way. Over the past 25 years, numerous panels have studied the acquisition process. And while not a lot of improvement has been made, it seems that the right efforts—rules and reviewing bodies—are now in place to make things better. An example is the Weapon Systems Acquisition Reform Act of 2009 (WSARA), which took steps to encourage the DoD to engage in a more robust discussion of trade-offs before beginning a new weapon system program. Part of the WSARA directed the DoD’s Joint Requirements Oversight Council (JROC) to ensure that these choices were made part of its process for assessing and prioritizing requirements. WSARA also directed GAO to assess the implementation of these requirements. In a report to the Congressional Armed Services Committees last month, the GAO reviewed its analysis on the extent to which the JROC has considered cost, schedule and performance trade-offs within programs. The report also looked at efforts to estimate the level of resources needed to fulfill joint military requirements and the extent to which the JROC is prioritizing requirements and capability gaps. To conduct its review the GAO focused on JROC activities in fiscal year 2010. It chose that time period to allow for any changes the JROC would implement as a result of the enactment of WSARA in May 2009. It reviewed the seven Capability Development Documents (CDD) submitted to the JROC in fiscal year 2010, JROC decision memos related to the CDDs, and analyses of alternatives (AOA) conducted by the military services prior to JROC reviews. The GAO also reviewed documentation from 15 JROC reviews of programs that incurred substantial cost growth [ 66 ] COTS Journal July 2011

after program start to determine if trade-offs were made. According to the GAO report, the JROC considered trade-offs made by the military services before validating requirements for four of the seven proposed programs it reviewed in fiscal year 2010, and provided input to the military services on the cost, schedule and performance objectives for two of the seven programs. The GAO report said that the JROC did not change any performance parameters during 15 reviews of programs that reported substantial cost growth in fiscal year 2010. For its part, the Joint Staff disagrees with that assessment arguing that by holding requirements firm and accepting increased cost and schedule delays, the JROC essentially traded cost and possibly schedule for performance. In fiscal year 2010 the JROC reviewed six programs after they experienced a critical Nunn-McCurdy breach, and nine programs as part of the tripwire process. During all 15 reviews, the DoD and the JROC stated that requirements were not the primary causes of cost growth. Most of these programs were in production in fiscal year 2010, and to be fair, changing requirements at this late stage might not have mitigated the reported cost growth. When the JROC reviewed the Family of Advanced Beyond Line-of-Sight Terminals program—still in development—it concluded that the program’s requirements could not be met in an affordable manner. The JROC did not immediately defer any of the program’s requirements. Instead it asked the USD AT&L to identify potential alternatives for the program, including reviewing whether adjustments to performance requirements would be appropriate. In summary, the GAO report concluded that the JROC has mostly left prioritization and trade-off decisions to the military services. The problem with that is it fails to make use of the unique, joint perspective of a body like the JROC, which enables it to look across the entire department to identify efficiencies and potential redundancies. So bottom line, there are it seems all the right rules and organizations in place to improve defense acquistion dramatically, but they have to be used. Hopefully the things like trade-off discussions at early acquisition milestones will help. More effectively scrutinizing the quality of the resource estimates presented by the military services should also make a difference. But it seems like those things won’t happen until that long-used term “Joint” becomes all that it should be in the acquistion side of our military.
