Security Testing and Spoofing

This lecture discusses the importance of security testing, focusing on techniques like fuzzing and sanitization to detect bugs and vulnerabilities in software. It also covers the concept of spoofing, specifically ARP spoofing, which exploits the lack of integrity in IP-MAC pairs to break confidentiality. The instructor presents real-world examples of companies forced to change their names due to security risks and explores the implications of encryption bans following terrorist attacks. Additionally, the lecture delves into the desired properties of network security, including confidentiality, integrity, availability, authentication, and authorization.
