Computer Network Security
Final Exam
Course Introduction
Computer Network Security is a comprehensive course that explores the principles, protocols, and practices designed to protect data and resources in computer networks from unauthorized access, misuse, or attack. Students will investigate topics including cryptography, authentication, firewalls, intrusion detection systems, virtual private networks, and security protocols. The course covers the analysis of vulnerabilities in networks, risk assessment techniques, and the implementation of security policies and countermeasures. By examining both theoretical foundations and practical applications, students gain essential skills for designing and managing secure network infrastructures in today's interconnected digital environment.

Q1) What was the criteria used by the IEEE 802.11 committee to design WEP?
Answer: The IEEE 802.11 committee designed WEP to meet the following criteria:
* Efficient-The WEP algorithm must be proficient enough to be implemented in either hardware or software.
* Exportable-WEP must meet the guidelines set by the U.S. Department of Commerce so that the wireless device using WEP can be exported overseas.
* Optional-The implementation of WEP in wireless LANs is an optional feature.
* Reasonably strong-The security of the algorithm lies in the difficulty of determining the secret keys through attacks. This in turn is related to the length of the secret key and the frequency of changing keys. WEP was to be "reasonably" strong in resisting attacks.
* Self-synchronizing-When using WEP, each packet must be separately encrypted. This is to prevent a single lost packet from making subsequent packets indecipherable.
Q2) ____________________ is the science of transforming information so that it is secure while it is being transmitted or stored.
