Objective 2: Set Up Host Security
As mentioned previously, the key to good host security is knowledge. A good system administrator knows at all times what is happening on systems he manages, and has processes in place to tell him when things stray from the norm.
Previous chapters have covered the topics of shadow passwords, knowledge of the /proc filesystem, maintaining startup services in /etc/rc.d, and other areas of host-based security. This chapter will finish this topic by discussing the inetd and xinetd services, and their role in system security.
