Chapter 1. Linux Security Problems
In this chapter, we will discuss the following:
- The security policy of Linux
- Configuring password protection

- Making use of sudoers – configuring sudo access
- Scanning hosts with Nmap
- Gaining a root on a vulnerable Linux system
Introduction
A Linux machine is only as secure as an administrator configures it to be. Once we are done with the installation of the Linux OS and we remove its unnecessary packages after the installation has been completed, we can start working on the security aspect of the software and the services provided by the Linux machine.
