Chapter 6. Maintaining System Security Using OpenSCAP

The Security Certification and Authorization Package (SCAP) is a standardized compliance checking solution for enterprise-level Linux infrastructures. It is a line of specifications maintained by the National Institute of Standards and Technology (NIST) for maintaining system security for enterprise systems.
Red Hat Satellite Server 5.5 and later use OpenSCAP to implement the SCAP specifications. OpenSCAP is an auditing tool that utilizes the Extensible Configuration Checklist Description Format (XCCDF). XCCDF is a standard way of expressing checklist content and defines security checklists. It also combines with other specifications such as Common Platform Enumeration (CPE), Common Configuration Enumeration (CCE), and Open Vulnerability and Assessment Language (OVAL), to create a SCAP-expressed checklist that can be processed by SCAP-validated products.

6.1. OpenSCAP Features

OpenSCAP verifies the presence of patches by using content produced by the Red Hat Security Response Team (SRT), it checks system security configuration settings, and examines systems for signs of compromise by using rules based on standards and specifications.
