Exam 19: Computer and Network Security Techniques

Which security area is addressed in IEEE 802.11i ?

SSL performs encryption first,followed by computing a message authentication code.

__________ is a monitored behavior.

Intrusion detection is based on the assumption that the behavior of the intruder differs from that of a legitimate user in ways that can be quantified.

Generic decryption (GD)technology enables the antivirus program to easily detect even the most complex polymorphic viruses while maintaining fast scanning speeds.

Ipsec is based primarily upon the DES standard.

A _________ is a hardware or software entity inserted between a system or network to be protected and the Internet or other outside access network to control traffic in both directions to enforce a security policy.

A(n)__________ looks for user behavior that differs from that expected from a legitimate user.

The ideal solution to the threat of viruses is:

Malware defense can involve a combination of prevention,__________,and removal.

Transport mode in IPSec provides protection to the entire IP packet.

In order to accelerate the introduction of strong security into WLANs,the Wi-Fi Alliance promulgated __________ as a Wi-Fi standard.

IEEE 802.11i consists of two main functions: authentication and access control.

The most complex part of SSL is the ___________ Protocol.

Ports are logical entities defined within the authenticator and refer to physical network connections.

An uncontrolled port allows the exchange of PDUs between a supplicant and other systems on the LAN only if the current state of the supplicant authorizes such an exchange.

The ________________ facility enables communicating nodes to encrypt messages to prevent eavesdropping by third parties.

The higher-layer protocols defined as part of SSL include:

The Host-based IDS monitors network traffic for particular network segments or devices and analyzes network,transport, and application protocols to identify suspicious activity.

Which of the following is not a central element of a typical antivirus scheme?
