Permission

Definitions

1. A rule or attribute that grants or denies a subject (user, role, or process) the ability to perform a specific action on a resource. In Unix, file permissions are expressed as read/write/execute bits for owner, group, and others; in applications, permissions are often managed through RBAC or ACL systems.

   In plain English: A setting that controls who is allowed to do what with a specific file, feature, or resource.

   Example: "The deploy bot only has read permission on the secrets vault — it can fetch credentials but can't rotate them."
