Security Guide

This manual introduces the basic concepts of system security on openSUSE. It covers extensive documentation about authentication mechanisms available on Linux, such as NIS or LDAP. It also deals with aspects of local security like access control lists, encryption and intrusion detection. In the network security part you learn how to secure your computers with a firewall and masquerading and how to set up virtual private networks (VPN). This manual also shows how to make use of the product inherent security software like Novell AppArmor (which lets you specify per program which files the program may read, write, and execute) or the auditing system that reliably collects information about any security-relevant events.

Many chapters in this manual contain links to additional documentation resources. This includes additional documentation that is available on the system as well as documentation available on the Internet.
