Methods of Checking SELinux Status on CentOS 8įor checking the status of SELinux on CentOS 8, you can use any of the three methods described below. If it is enabled, then in which mode is it operating? Is it “Enforcing” or “Permissive”? In this situation, we must have proper ways where we can inquire for the status of SELinux.įor knowing the different methods of checking SELinux status on CentOS 8, you need to go through the following section of this article. They need to specifically query for its status to know if SELinux is enabled or disabled. Since it is a mechanism that runs in the background, therefore, the users are not aware of its status. It means that you should ensure all the time that SELinux is enabled and running on your system, unless you encounter a situation in which you have to disable it explicitly. We have already stated that the security of the Linux based systems relies entirely on SELinux. Use Case of Checking the Status of SELinux on CentOS 8Īfter reading the introduction of this article, you might be wondering why do we need to check the status of SELinux in the first place. However, today we would like to share with you the method of checking the status of SELinux on CentOS 8. For this reason, unless you have a valid purpose to disable it, it is suggested to keep SELinux in enforcing mode. SELinux allows you the power to restrict the rights related to the process execution and mitigate the damage that might emerge from the exploitation of vulnerabilities in applications and systems. In our previous article on SELinux, we shared with you the method of disabling it. Each of these modes serves a different purpose and you should understand it fully before changing the default mode of SELinux. This security mechanism has three different modes of operation, i.e., “Enforcing”, “Permissive”, and “Disabled”, and you can toggle between these three modes according to your specific work requirements. SELinux 8 is a built-in security mechanism on which the security of all the Linux based systems depends. As a substitute for Discretionary Access Control (DAC) that ships with most Linux distributions, SELinux was formed.
SELinux is a Mandatory Access Control (MAC) system that is developed by the NSA.
