Definition: I believe "AppArmor.conf" refers to a file used in Linux kernel for security, defining configuration parameters that can be applied to all apparmor entries. Detailed definition: AppArmor is an application layer security policy that provides context-specific security policies on applications running as root or other privileged processes. It enables the use of secure apps with minimal system requirements and uses a configuration file called "apparmor.conf" to define these policies. The term comes from "Application Profile Mode, Security" in Unix/Linux, which refers to the way Linux handles security policies for user-initiated applications. To apply these policies, an apparmor entry is typically created that specifies the context it wants to protect and how to treat certain types of files or data. It can also provide additional settings such as permissions, access modes, and other flags used by security policies. The apparmor.conf file defines these contexts for various types of apps based on their configuration parameters.
