If configured, this prevents users from executing malicious files from their home directories. For example, mapping a Linux user to the SELinux user_u user, results in a Linux user that is not able to run (unless configured otherwise) set user ID (setuid) applications, such as sudo and su, as well as preventing them from executing files and applications in their home directory. Linux users can be mapped to confined SELinux users to take advantage of the security rules and mechanisms applied to them. A number of confined SELinux users exist in SELinux policy. If an SELinux policy rule does not exist to allow access, such as for a process opening a file, access is denied. SELinux can be used to enforce data confidentiality and integrity, as well as protecting processes from untrusted inputs. For example, if the Apache HTTP Server is compromised, an attacker cannot use that process to read files in user home directories, unless a specific SELinux policy rule was added or configured to allow such access. If a process is compromised, the attacker only has access to the normal functions of that process, and to files the process has been configured to have access to. SELinux policy rules define how processes access files and other processes. Processes run in domains, and are therefore separated from each other.

Improved mitigation for privilege escalation attacks. SELinux policy is administratively-defined and enforced system-wide. Stepping beyond traditional UNIX permissions that are controlled at user discretion and based on Linux user and group IDs, SELinux access decisions are based on all available information, such as an SELinux user, role, type, and, optionally, a security level. Access is only allowed if an SELinux policy rule exists that specifically allows it.įine-grained access control. SELinux policy rules define how processes interact with files, as well as how processes interact with each other.
