About this Course
Red Hat® Server Hardening (RH413) builds on a student's Red Hat Certified Engineer (RHCE®) certification or equivalent experience to teach how to secure a Red Hat Enterprise Linux® system to comply with security policy requirements. Many security policies and standards require systems administrators to address specific user authentication concerns, application of updates, system auditing and logging, file system integrity, and more. Red Hat Server Hardening provides strategies for addressing specific policy and configuration concerns.
