QUESTION 1
(a) Is an intrusion avoidance system more like a honeypot or a firewall? Describe Why?
(b) What does the quality of its random number generator have to do with the ability of a worm to multiply quickly?
(c) Cryptography can be used for many things. For instance, it could be used to encrypt data to be archived on a tape for many years, or it could be used to protect a critical message being sent across the Internet. Are the issues of key assortment the same or different for these two cases?
(d) Why is error handling significant issue for writing secure code?
QUESTION 2
(a) Briefly describe the following kinds of attacks.
a. Deal out the Denial-Of-Service (DDoS).
b. IP Spoofing .
(b) Give explanation of the concept of Public Key Infrastructure (PKI).
(c) Illustrate what you understand by a Certificate Authority.
(d) Show by means of an illustration how a Certificate Authority works.
QUESTION 3
(a) In brief describe the two (2) authentication mechanisms in Wireless LANs.
(b) As a WLAN Administrator, one has the option to make all communication over the air encrypted using the WEP Protocol. Portray the three (3) components in the WEP Protocol.
(c) Exemplify on four (4) of the shortcomings of the WEP Protocol.
QUESTION 4
(a) Demonstrate using any Programming Language how you would represent and perform the RSA Algorithm.
