Chapter Summary

This final chapter covered several additional new vulnerabilities and described how they are used to attack systems. Understanding these common attacks is crucial for understanding what the rest of the chapter explained. Security assessments and penetration testing are effective tools that, if used correctly, enable your network to be evaluated by qualified engineers who deploy the proper security analysis tools to find the vulnerabilities. A good security assessment, however, covers more than just the logical vulnerabilities in your network. The remainder of this chapter was dedicated to the various security scanning tools that are available, some of which are free open source solutions.
