Unit 6: Firewalls, Intrusion Detection, and Intrusion Prevention
In this unit, we will explore the use of security tools such as firewalls and intrusion prevention systems. Following a quick introduction to the concepts of intranet and extranet systems that are frequently used for information exchange by enterprises today, we will look into cryptographic concepts related to securing communication using firewalls. We will explore how firewalls work and will also study different types of intrusion detection systems including host-based and network-based systems.
