| 5 | <para>Security takes many forms in a computing environment. This chapter
|
|---|
| 6 | gives examples of three different types of security; access, prevention
|
|---|
| 7 | and detection. Access for users is usually handled by
|
|---|
| 8 | <command>login</command> or an application designed to handle the login
|
|---|
| 9 | function. In this chapter, we show how to enhance
|
|---|
| 10 | <command>login</command> by setting policies with
|
|---|
| 11 | <application><acronym>PAM</acronym></application> modules. Access via networks
|
|---|
| 12 | can also be secured by policies set by
|
|---|
| 13 | <application>iptables</application>. Prevention of breaches, like
|
|---|
| 14 | trojans, are assisted by applications like <application>gnupg</application>,
|
|---|
| 15 | specifically the ability to confirm signed packages, which prevents
|
|---|
| 16 | modification of the tarball after the packager creates it. Finally, we touch on
|
|---|
| 17 | detection with a package that stores "signatures" and then regenerates those
|
|---|
| 18 | "signatures" and compares for files that have been changed.</para>
