5<para>Security takes many forms in a computing environment. This chapter
6gives examples of three different types of security: access, prevention
7and detection.</para>
8
9<para>Access for users is usually handled by <command>login</command> or an
10application designed to handle the login function. In this chapter, we show
11how to enhance <command>login</command> by setting policies with
12<application><acronym>PAM</acronym></application> modules. Access via networks
13can also be secured by policies set by <application>iptables</application>,
14commonly referred to as a firewall.</para>
15
16<para>Prevention of breaches, like a trojan, are assisted by applications like
17<application>GnuPG</application>, specifically the ability to confirm signed
18packages, which recognizes modifications of the <acronym>TAR</acronym> ball after
19the packager creates it.</para>
20
21<para> Finally, we touch on detection with a package that stores "signatures"
22of critical files (defined by the administrator) and then regenerates those
23"signatures" and compares for files that have been changed.</para>
