This section describes Oracle Linux features that administrators can use to manage system security.

Oracle Linux provides a complete security stack, from network firewall control to access control security policies, and is configured to be secure by default. Oracle Linux includes features that can help you to enhance system security, such as real-time patching, automated software updates, certificate management tools, a built-in firewall, mandatory access controls, and public key cryptography and data encryption tools. This section describes each of these features and discuss where you can find more information.

Consider using a combination of these tools and facilities to manage access that's provisioned on the system and improve the security of the OS, applications that run on the system and network connectivity.
