www.640-553.com Q: 1 Exam Description and Topics Exam Description The 640-553 Implementing Cisco IOS Network Security (IINS) exam is associated with the CCNA Security certification. This exam tests a candidate's knowledge of securing Cisco routers and switches and their associated networks. It leads to validated skills for installation, troubleshooting and monitoring of network devices to maintain integrity, confidentiality and availability of data and devices and develops competency in the technologies that Cisco uses in its security infrastructure. Exam Topics The following topics are general guidelines for the content likely to be included on the Implementing Cisco IOS Network Security (IINS) exam. However, other related topics may also appear on any specific delivery of the exam. In order to better reflect the contents of the exam and for clarity purposes, the guidelines below may change at any time without notice.

Topic-1 Describe the security threats facing modern network infrastructures. (15 Questions) Describe and list mitigation methods for common network attacks Describe and list mitigation methods for Worm, Virus, and Trojan Horse attacks Describe the Cisco Self Defending Network architecture

Topic-2 Secure Cisco routers . (24 Questions) Secure Cisco routers using the SDM Security Audit feature Use the One-Step Lockdown feature in SDM to secure a Cisco router Secure administrative access to Cisco routers by setting strong encrypted passwords, exec timeout, login failure rate and using IOS login enhancements Secure administrative access to Cisco routers by configuring multiple privilege levels Secure administrative access to Cisco routers by configuring role based CLI Secure the Cisco IOS image and configuration file

www.640-553.com Q: 4 Examine the following options, when editing global IPS settings, which one determines if the IOS-based IPS feature will drop or permit traffic for a particular IPS signature engine while a new signature for that engine is being compiled?

A. Enable Engine Fail Closed B. Enable Fail Opened C. Enable Signature Default D. Enable Default IOS Signature

B. Using password-cracking utilities C. Performing end-user training on the use of antispyware software D. Performing virus scans

Answer: A, B, D www.640-553.com Q: 7 The enable secret password appears as an MD5 hash in a router's configuration file, whereas the enable password is not hashed (or encrypted, if the password-encryption service is not enabled). What is the reason that Cisco still supports the use of both enable secret and enables passwords in a router's configuration?

A. The enable password is used for IKE Phase I, whereas the enable secret password is used for IKE Phase II. B. The enable password is considered to be a router's public key, whereas the enable secret password is considered to be a router's private key. C. Because the enable secret password is a hash, it cannot be decrypted. Therefore, the enable password is used to match the password that was entered, and the enable secret is used to verify that the enable password has not been modified since the hash was generated. D. The enable password is present for backward compatibility.

Answer: D www.640-553.com Q: 8 On the basis of the description of SSL-based VPN, place the correct descriptions in the proper locations. Answer & Explanation Correct Answer Explanations(Click me to Show) This question is to examine the knowledge related to SSLVPN.

SSL VPN uses the RSA or DH technologies rather than HASH (SHA-1, MD5) algorithm for authentication and key exchange. Asymmetric algorithms are used for authentication and key exchange of SSL VPN. Symmetric algorithms (such as des, 3DES, AES, RC4, etc.) are applied to encryption. Unlike IPSec VPN, SSL VPN uses an easier way to achieve remote connection of information and can be used by any browser-installed machine.
