Capability lists, often referred to as capability lists or caplists, are a fundamental concept in security and access control systems. They represent a set of permissions or rights granted to a specific entity, such as a user, a group, or a process. These lists define what actions an entity is allowed to perform on certain resources.

The core idea behind capability lists is to associate permissions directly with the entity that needs them, rather than centrally managing permissions on the resources themselves. This approach can offer a more decentralized and flexible way to handle access control. When an entity possesses a capability, it can exercise the associated right without further checks, as the capability itself serves as proof of authorization.

In practice, capability lists can be implemented in various ways. They might be stored as part of a user's profile, embedded within security tokens, or managed by a dedicated access control service. The granularity of capabilities can vary widely, from broad permissions like "read access to all files" to highly specific actions like "edit this particular record in the database."

The use of capability lists can enhance security by providing a clear and auditable record of granted permissions. However, managing them effectively requires careful design to avoid complexity and potential security loopholes. Organizations often combine capability lists with other access control mechanisms, such as role-based access control (RBAC), to create robust security frameworks.
