What command switches SELinux into permissive mode?

• A. setenforce 0
• B. /etc/init.d/selinux stop
• C. selinux passive
• D. /etc/init.d/selinux startpassive

Answer: (A)

To enable permissive mode in SELinux, the command used is "setenforce 0." This command instructs the SELinux system to change its enforcement mode from enforcing to permissive. In permissive mode, SELinux does not enforce policies that govern process execution and access but instead logs actions that would have been denied if in enforcing mode. This is particularly useful for troubleshooting and development purposes, allowing administrators to see what would be blocked without actually enforcing the policies. The other commands listed do not achieve this functionality. For example, stopping SELinux or starting it in some passive mode is either not valid or does not correspond to changing enforcement states. Understanding the specific function of the "setenforce" command is critical for effectively managing SELinux configurations.
