Red Hat Training

A Red Hat training course is available for Red Hat Enterprise Linux

Part VII. Security And Authentication

Whether system administrators need to secure their mission-critical systems, services, or data, Red Hat Enterprise Linux provides a range of tools and methods to serve as part of a comprehensive security strategy.
This chapter provides a general introduction to security, and from the perspective of Red Hat Enterprise Linux in particular. It provides conceptual information in the areas of security assessment, common exploits, and intrusion and incident response. It also provides conceptual and specific configuration information on how to use SELinux to harden Workstation, Server, VPN, firewall and other implementations.
This chapter assumes a basic knowledge of IT security, and consequently provides only minimal coverage of common security practices such as controlling physical access, sound account-keeping policies and procedures, auditing, etc. Where appropriate, reference is made to external resources for this and related information.
