Redhat Server Hardening (RH413) builds on a student’s Redhat Certified Engineer (RHCE) certification or equivalent experience to teach how to secure a Redhat 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. Redhat Server Hardening provides strategies for addressing specific policy and configuration concerns.
Prerequisite: Knowledge of linux and Networking
Redhat Server Hardening (RH413) is the security level certification from Redhat. Redhat Server Hardening certification training in addition to the Redhat Certified Engineer (RHCE) certification provides in depth exposure to secure a Redhat Enterprise Linux system in compliance with the security policy requirements. Systems administrators have to address many security policies and standards, which require specific to user authentication concerns, application of updates, system auditing and logging, file system integrity, etc. Redhat Server Hardening . RH413 training provides the strategies for addressing specific policy and configuration concerns.
In computing, server hardening is usually the process of securing a system by reducing its surface of vulnerability. A system has a larger vulnerability surface as it fulfills more functions; in principle a single-function system is more secure than a multi-purpose one. Reducing the available vectors of attack typically includes the removal of unnecessary software, unnecessary usernames or logins and disabling or removal of unnecessary services.
Duration: 10days or 4 days (Full Day Training)
