Build on your Red Hat Certified Engineer (RHCE) certification or equivalent experience by learning 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.
1. Manage Software Updates
Develop a process for applying updates to systems, including verifying properties of the update.
2. Create File Systems
Allocate an advanced file system layout, and use file system encryption.
3. Manage File Systems
Adjust file system properties through security-related options and file system attributes.
4. Manage Special Permissions
Work with set user ID (SUID), set group ID (SGID), and sticky (SVTX) permissions, and locate files with these permissions enabled.
5. Manage Additional File Access Controls
Modify default permissions applied to files and directories, and work with file access control lists.
6. Monitor for File System Changes
Configure software to monitor the files on your machine for changes.
7. Manage User Accounts
Set password-aging properties for users; audit user accounts.
8. Manage Pluggable Authentication Modules (PAMs)
Apply changes to PAMs to enforce different types of rules on users.
9. Secure Console Access
Adjust properties for various console services to enable or disable settings based on security.
10. Install Central Authentication
Install and configure a Red Hat Identity Management server and client.
11. Manage Central Authentication
Configure Red Hat Identity Management rules to control both user access to client systems and additional privileges granted to users on those systems.
12. Configure System Logging
Configure remote logging to use transport layer encryption, and manage additional logs generated by remote systems.
13. Configure System Auditing
Enable and configure system auditing.
14. Control Access To Network Services
Manage firewall rules to limit connectivity to network services.
