Objective

To guide users through the process of creating a job in SanerCVEM that sets the SELinux status on Unix-based systems. This is essential for managing system security policies and ensuring appropriate enforcement levels.

Need for the Task

SELinux (Security-Enhanced Linux) is a critical security module that enforces access control policies. Administrators may need to switch between "enforcing" and "permissive" modes depending on operational requirements, troubleshooting needs, or policy testing.

Form Field Explanations

- Operating System Family: Select "Unix" to target Linux systems.

- Action: Choose "Set SELinux Status" to configure SELinux mode.

- SELinux Status: Select either "enforcing" (active policy enforcement) or "permissive" (log-only mode).

- Response Name: Provide a clear name like "set selinux status".

- Response Description: Describe the purpose, e.g., "Switch SELinux to permissive mode".

- Target: Select the appropriate Unix-based device(s), such as "ubuntu".

- How Often: Choose "Immediate" or schedule as needed.

Note on Importance of SELinux

SELinux is a powerful security feature that confines user programs and system services to the minimum privileges required. Setting SELinux to "enforcing" ensures strict policy enforcement, enhancing system security. In "permissive" mode, actions are logged but not blocked, which is useful for testing and troubleshooting.

Conclusion

Using SanerCVEM to manage SELinux status provides administrators with centralized control over security enforcement. This approach ensures consistent policy application across multiple Unix endpoints and simplifies compliance management.
