Documentation Conventions

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

Many chapters in this manual contain links to additional documentation resources. These include additional documentation that is available on the system, and documentation available on the Internet.
