Chapter 4. Securing the Network
Defense in depth is a foundational concept of information security. Each tier of the enterprise network needs to be secured to mitigate attacks against assets at each tier. This chapter will introduce multiple technologies that can be implemented in the network to secure enterprise infrastructure, network services such as e-mail, DNS, file transfer, and web applications. Advancement in firewall technologies that provide more in-depth inspection and protection capabilities will be covered as a method to consolidate solutions and increase visibility into the network traffic.
