Network Security: Strong Safeguarding Techniques Nowadays computers, network and Internet are as vital as the air to breathe. Computers have become an integral part of our lives, people have been storing all their valuable data and information on the computers and when there arises a need to share or transfer this information with other people “network” comes in. The dictionary defines “network” as ``any set of interlinking lines resembling a net, a network of roads, an interconnected system, a network of alliances.’’ Based on this a computer network can be defined simply as a system of interconnected computers. The network facilitates remote access to geographically distant resources minus the physical presence. It is also designed to send data back and forth and stay connected in a globalized business environment. In today’s competitive world business expansion scenarios, sharing information on the network necessitates confirming the security and safety of the information from outside threats. Networks are vulnerable because of their inherent characteristic of facilitating remote access. Organization mostly depends on the firewalls installed in the IP network, and the server generated traffic logs to maintain the information security posture. This is where information security and network security comes into play. Monitoring thousands of devices in a wide network is a mammoth task. Besides with the number of emerging threats, constraint security budgets, and varied compliance requirements, enterprises look for outsourcing this responsibility to experts who have managed security services. The purpose of network security is quite simply to protect the network and its component parts from unauthorized access and misuse. When security is an issue, being informed is essential. Network design, the applications used, traffic flow, and understanding of security threats are just some of the topics that one should be aware of when dealing with network security. A recent survey conducted by the Computer Security Institute, states 70 percent of the organizations polled admitted breach of their network security defenses and that 60 percent of the attack on information security came from within the organizations. With the business transactions done over the Internet, rise of e-commerce and wireless networks, organizations need to ensure that security solutions be flawlessly integrated, more transparent, and more flexible. The managed security service providers offer real-time protection to the organizations and thereby reduce the risks involved in an ever-changing threat environment. With a balanced approach, proactive security posture, a techno centric focus and a flexible delivery model, these security service providers also ensures that the enterprises meet the regulatory compliances of global standards. Further, with the growth of information exchange across geographical boundaries, and across wide networks brings in threats to the confidentiality, integrity and availability of information as well as cyber threats, malware infections, phishing attack and web application attacks. It is thus important to build strong networks security systems with end to end capability and the key for building such a secure network is to first to
