Mastering Linux Security and Hardening - Second Edition

Summary

We covered a lot of ground in this chapter, and we saw some really cool stuff. We began by looking at a couple of antivirus scanners so that we can prevent infecting any Windows machines that access our Linux servers. In the Scanning for rootkits with Rootkit Hunter section, we saw how to scan for those nasty rootkits. We also saw a couple of quick techniques to examine a potentially malicious file. It's important to know how to audit systems, especially in high-security environments, and we saw how to do that. Finally, we wrapped things up with a discussion of hardening our systems with OpenSCAP.

In the next chapter, we'll look at logging and log file security. I'll see you there.
