capability

[‚kāp·ə′bil·ə·dē]
(computer science)
A permission that is given to a user of a computing system in advance to access a particular object in the system in a particular way, and that the user can later present to a reference monitor as a prevalidated ticket to gain access.

capability

(operating system, security)
An operating system security or access control model where specific types of access to a specific object are granted by giving a process this data structure or token.

The token may be unforgeable (typically by using encryption or hardware "tagged" memory). Capabilities are used in OSes such as Hydra, KeyKOS, EROS, Chorus/Mix, and the Stanford V system. Similar to Kerberos, but in an OS context.

Compare access control list.

capability

In information security, an indicator (token, semaphore, etc.) that authorizes an access mode to an object such as a file or a device for a specific user or process. See also privilege.
