"Minimize the amount of software installed and running in order to minimize
vulnerability."

http://www.nsa.gov/snac/os/redhat/rhel5-guide-i731.pdf
"1.1.2 Minimize Software to Minimize Vulnerability
The simplest way to avoid vulnerabilities in software is to avoid installing
that software. On RHEL, the RPM Package Manager (originally Red Hat Package
Manager, abbreviated RPM) allows for careful management of the set of
software packages installed on a system. Installed software contributes to
system vulnerability in several ways. Packages that include setuid programs
may provide local attackers a potential path to privilege escalation.
Packages that include network services may give this opportunity to
network-based attackers. Packages that include programs which are
predictably executed by local users (e.g. after graphical login) may provide
opportunities for trojan horses or other attack code to be run undetected.
The number of software packages
installed on a system can almost always be significantly pruned to include
only the software for which there is an environmental or operational need."


And there is not only NSA, especially for european users...
