SELinux (Security-Enhanced Linux) is a security module that provides a mechanism for supporting access control security policies. It helps to limit the resources a process can access, enhancing overall system security. Best practices are procedures or steps in a particular field of expertise that are generally accepted as being effective. They are formed by professionals reaching an agreement and share consensus-based tips with others in and outside the field.

This way you always have the option to go back to a previous configuration, if for some reason things fail. Hardening the operating system means changes to its configuration will happen.

High availability and reliability help provide uninterrupted access to services, maintain data integrity and deliver exceptional user experiences. New features in RHEL streamline Linux Hardening and Security Lessons recovery operations across hybrid cloud environments. Safeguarding sensitive data, protecting against cyber threats and adhering to regulatory requirements are essential tasks.

The following is a list of security and hardening guides for several of the most popular Linux distributions. The multi-arch build farm feature lets you dispatch builds to Podman hosts on different platforms, easing multiarchitecture container builds. You can also combine multiple command line options in a single, reusable module to simplify management of complex sets of flags. It’s no surprise that today’s IT environments are more complex than ever before. A mix of old and new technologies, disparate teams and outdated manual processes often result in inefficient operations, security and compliance risks and overburdened IT teams.
