Using Linux Securely
Getting and keeping your Linux systems secure means not only making good decisions about how
you initially set up your system but also how you use it going forward. Whether you are using your
Linux system as a desktop or server system, good security practices related to passwords, using
secure applications, and monitoring log files are always important.
Setting up a secure firewall (as described in Chapter 18) is critical to having a secure Linux system.
There are also other security measures you should apply to Linux. This section describes some
good practices for using passwords, keeping track of system activity by watching log files, and
communicating with other systems using Secure Shell (ssh) applications.
