semanage

semanage is a command line tool used in Linux based operating systems, developed by the National Security Agency (NSA). It stands for Security Enhanced Linux (SELinux) management tool and is used to manage SELinux policies.

The primary purpose of semanage is to manage and control various aspects of SELinux policies. It allows system administrators to modify SELinux settings, assign labels to files and directories, define policy modules, and tweak other security-related configurations.

With semanage, administrators can add, modify, and delete SELinux policy rules. They can also view the current SELinux policy configurations and run diagnostics to troubleshoot policy issues.

Apart from managing SELinux policies, semanage also provides the ability to manage SELinux user mapping, allowing administrators to map SELinux users to Linux users and vice versa.

It provides a user-friendly and straightforward command line interface, making it suitable for both experienced administrators and newcomers to SELinux. The tool offers extensive documentation, helping users understand various commands and their functionalities.

semanage is a powerful utility in securing Linux systems by implementing fine-grained access control and enforcing mandatory access controls through SELinux policies. It greatly enhances the security and helps prevent unauthorized access or malicious activities on the system.
