Chapter 13. Application-Level Risks

In this chapter, I focus on application-level vulnerabilities and mitigation strategies. The effectiveness of firewalls and network segmentation mechanisms is severely impacted if vulnerabilities exist within accessible network services. In recent years, major security flaws in Unix and Windows systems have been exposed, resulting in large numbers of Internet-based hosts being compromised by hackers and worms alike.
