Where is the SELinux configuration file located?

The SELinux configuration file is indeed located at /etc/selinux/config. This file is critical for configuring the Security-Enhanced Linux (SELinux) settings on a system. It defines the SELinux policy that the system should be using, as well as the mode in which SELinux operates, such as enforcing, permissive, or disabled.

This location is standard across most Linux distributions that implement SELinux, making it a reliable reference point for system administrators and security professionals who need to manage SELinux policies. By accessing the /etc/selinux/config file, administrators can easily modify the SELinux settings to enhance the security posture of their systems by defining how applications comply with predefined security policies.

The other suggested locations are not used for the SELinux configuration file. /usr/share/selinux/config, for instance, is not a standard path where configuration files for SELinux are kept. Similarly, /var/lib/selinux/config and /bin/selinux/config do not serve this purpose and do not follow the conventional structure expected for configuration files related to SELinux. Therefore, recognizing /etc/selinux/config as the correct and established location is essential for effective SELinux management and configuration.
