Files and directories have permissions that establish who can read, write, or execute content. Also, regular users are not allowed to do certain things that the root user can do. But these forms of security are not enough for today's world of sophisticated cyber attacks. They're just too generic and not fine tuned enough. And a simple read or write permission gives a user or process too much power over a particular area of the system. Fortunately, the Linux kernel can be easily extended with so-called modules, and there's a security module called SELinux that adds a very advanced capabilities of restricting access.
