12<para>Security takes many forms in a computing environment. This chapter
13gives examples of three different types of security: access, prevention
14and detection.</para>
16<para>Access for users is usually handled by <command>login</command> or an
17application designed to handle the login function. In this chapter, we show
18how to enhance <command>login</command> by setting policies with
19<application><acronym>PAM</acronym></application> modules. Access via networks
20can also be secured by policies set by <application>iptables</application>,
21commonly referred to as a firewall.</para>
23<para>Prevention of breaches, like a trojan, are assisted by applications like
24<application>GnuPG</application>, specifically the ability to confirm signed
25packages, which recognizes modifications of the <acronym>TAR</acronym> ball after
26the packager creates it.</para>
28<para> Finally, we touch on detection with a package that stores "signatures"
29of critical files (defined by the administrator) and then regenerates those
30"signatures" and compares for files that have been changed.</para>
