This course is designed to provide strategies on securing a Red Hat Enterprise Linux® system to comply with security policy requirements. The course addresses specific user authentication concerns, application of updates, system auditing and logging, file system integrity, and more. After attending this course, participants will be able to address security vulnerabilities in system configurations and installed packages. The course will provide insights on how to understand and respond to Common Vulnerabilities and Exposure (CVE) and Red Hat Security Advisory (RHSA) reports. The course equips participants with the essential skills such as deploying identity management to facilitate user account security policies and applying relevant errata to maintain system integrity.

This course is based on Red Hat Enterprise Linux 6.4.
