Introduction to Novell AppArmor

Many security vulnerabilities result from bugs in trusted programs. A trusted program

runs with privilege that some attacker would like to have and the program fails to keep

that trust if there is a bug in the program that allows the attacker to acquire that privilege.

Novell AppArmor is an application security solution designed specically to provide

least privilege connement to suspect programs. AppArmor allows the administrator

to specify the domain of activities the program can perform by developing a security

prole for that application—a listing of les that the program may access and the oper-

ations the program may perform.

Effective hardening of a computer system requires minimizing the number of programs

that mediate privilege then securing the programs as much as possible. With Novell

AppArmor, you only need to prole the programs that are exposed to attack in your

environment, which drastically reduces the amount of work required to harden your

computer. AppArmor proles enforce policies to make sure that programs do what they

are supposed to do, but nothing else.

Administrators only need to care about the applications that are vulnerable to attacks

and generate proles for these. Hardening a system thus comes down to building and

maintaining the AppArmor prole set and monitoring any policy violations or exceptions

logged by AppArmor's reporting facility.

Building AppArmor proles to conne an application is very straightforward and intu-

itive. AppArmor ships with several tools that assist in prole creation. AppArmor does

not require you to do any programming or script handling. The only task that is required

from the administrator is to determine a policy of strictest access and execute permissions

for each application that needs to be hardened.

Introduction to Novell AppArmor 7

Updates or modications to the application proles are only required if the software

conguration or the desired range of activities changes. AppArmor offers intuitive tools

to handle prole updates or modications.

Users will not notice AppArmor at all. It runs “behind the scenes” and does not require

any user interaction. Performance will not be affected noticeably by AppArmor. If some

activity of the application is not covered by an AppArmor prole or if some activity

of the application is prevented by AppArmor, the administrator needs to adjust the

prole of this application to cover this kind of behavior.

This guide outlines the basic tasks that need to be performed with AppArmor to effec-

tively harden a system. For more in-depth information, refer to Novell AppArmor

Installing Novell AppArmor

Users installing either a GNOME or the KDE desktop selection can skip this section,

because Novell® AppArmor is installed by default as part of these selections.

If installing neither of these desktops or even going for en entirely text-based environ-

ment, do the following to install the required packages using the YaST package manager.

1Log in as root and start YaST.

2In the YaST Control Center, select Software →Software Management.

3Use the search functionality of YaST (keywords “AppArmor” and “subdomain”)

to install the following packages:

• subdomain-parser-demo

• subdomain-parser-common

• libimmunix

• libimnxcert

• subdomain-docs

• yast2-subdomain

• subdomain-proles

• subdomain-leaf-cert

• subdomain-utils

Installing Novell AppArmor 9

4Select all these packages for installation then select Accept. YaST resolves any

dependencies and installs all the packages for you.

5After YaST has nished updating the system conguration, select Finish to leave

the package manager.
