Summary

In this chapter, we looked at how to lock down users’ home directories, how to enforce strong password policies, and how to enforce account and password expiration policies. Then, we talked about a way to prevent brute-force password attacks, how to manually lock out user accounts, how to set up security banners, and how to check for compromised passwords. We wrapped things up with a brief overview of central user management systems.

In the next chapter, we’ll look at how to work with various firewall utilities. I’ll see you there.
