Privilege

A privilege is the specific authorization granted to a user, application, or process to perform actions or access resources within an information system, forming a core element of access control and cybersecurity.

In cybersecurity, a privilege refers to the specific authorization granted to an authenticated entity—such as a user, application, or system process—to perform particular actions or access designated resources within an information system. Privileges define the precise permissions that dictate what an entity can do, including reading, writing, modifying, executing, or deleting files, accessing databases, or administering critical system functions. They are a fundamental component of Identity & Access Management (IAM) and serve as a key security control for safeguarding sensitive data and digital assets.

The meticulous management of privileges is essential for establishing a strong security posture. Adherence to the principle of least privilege—granting only the minimum permissions necessary for legitimate tasks—is a cornerstone practice that significantly reduces the attack surface. Proper privilege management helps prevent unauthorized access, limits the impact of security incidents, supports regulatory compliance, and defends against both internal misuse and external threats across an organization's entire digital ecosystem.
