SELinux is a Linux kernel security module that provides mandatory access control policies and confines user programs and system services. Learn about its history, architecture, features, and applications from the NSA and Red Hat developers.
Security-Enhanced Linux (SELinux) is a security architecture for Linux® systems that allows administrators to have more control over who can access the system.
What Is SELinux? SELinux is a special security system built into Linux computers. SELinux was created by the U.S National Security Agency and Red Hat company. The main purpose of the SELinux is to control what different programs and users are allowed to access on the computer. It does this by setting the strict rules. Without SELinux, if a program gets a virus or hacker access, that program ...
SELinux is a powerful security tool that enhances system protection through mandatory access control policies. While it can seem complex at first, understanding its modes, labels, and policy management tools makes it a valuable addition to any Linux system.
Learn how to use SELinux, a powerful security architecture that enforces mandatory access control and reduces vulnerabilities on Linux systems. This article explains the basics of SELinux, its policy models, and how to configure it for different modes and scenarios.
Learn what SELinux is, why it's important, and how to configure it on your Linux system. This article covers SELinux modes, policies, tools, and troubleshooting tips with examples and resources.
A given SELinux policy can be customized further based on a set of compile-time tunable options and a set of runtime policy booleans. system-config-selinux allows customization of these booleans and tunables. Many domains that are protected by SELinux also include SELinux man pages explaining how to customize their policy.
Learn what SELinux is, how it works, and how to manage it in Linux. This article covers the core concepts, modes, contexts, and practical examples of SELinux for beginners.
Security-Enhanced Linux (SELinux) is a Linux kernel security module that provides a mechanism for supporting access control security policies. It is a mandatory access control (MAC) mechanism that enhances the security of the Linux system by restricting access to system resources.
Learn how Security Enhanced Linux (SELinux) provides an additional layer of system security with fine-grained access control and policy rules. Find out the benefits, concepts, and examples of SELinux for Linux users and processes.
