What command could be used to provide a summary of the SELinux policy and current context?

The command that provides a summary of the SELinux policy and the current context is "sestatus." When executed, it displays information about the SELinux status, the current mode (enforcing, permissive, or disabled), the loaded policy name, and potentially any additional relevant context information. This summary is crucial for understanding the SELinux configuration and whether the system is actively enforcing security policies or not.

This command is part of the SELinux management toolkit and is commonly used by system administrators to verify and manage SELinux settings effectively. It is particularly valuable for troubleshooting and ensuring that security policies are correctly implemented and functioning as intended.

The other commands listed serve different purposes: "chage" is used to manage user password expiry information, "ulimit" deals with user process resource limits, and "getenforce" checks the current SELinux mode but does not provide as comprehensive a summary as "sestatus."
