Capability-based security is a concept in the design of secure computing systems, one of the existing security models. A capability (known in some systems as a key) is a communicable, unforgeable token of authority. It refers to a value that references an object along with an associated set of access rights. A user program on a capability-based operating system must use a capability to access an object. Capability-based security refers to the principle of designing user programs such that they directly share capabilities with each other according to the principle of least privilege, and to the operating system infrastructure necessary to make such transactions efficient and secure. Capability-based security is to be contrasted with an approach that uses hierarchical protection domains.

  • Con il termine capability si intende in informatica un meccanismo di protezione delle risorse orientato agli oggetti complementare alle ACL. I sistemi che utilizzano le capability associano a ciascun processo una lista di capability (o C-list), che descrive per l'appunto a quali oggetti (per esempio file) il processo può accedere. Una C-list può essere formata da dei nodi, ciascuno dei quali rappresenta i permessi su un determinato oggetto puntato.
