privileged function
163584·updated Sep 1, 2026A category of system operation whose execution carries security- or integrity-relevant consequences that ordinary users are not authorized to trigger—such as disabling or altering security controls, establishing accounts, performing integrity checks, administering cryptographic key material, or circumventing detection mechanisms. NIST SP 800-53 enumerates canonical examples as "disabling, circumventing, or altering implemented security or privacy controls, establishing system accounts, performing system integrity checks, and administering cryptographic key management activities." The category typically encompasses control, monitoring, or administration of a system and its security measures. In practice, the field uses the term to anchor least-privilege and separation-of-duties controls: misuse of privileged functions—whether intentional or unintentional, by authorized insiders or external actors who have compromised accounts—is treated as a serious risk, and logging their execution is a primary mitigation.

A web lookup ran when this term was proposed
An operation or capability within a system to which the delegation of authority — and therefore security consequence — is attached, meaning its execution can affect the security posture of the system. What distinguishes it from ordinary operations is that it encompasses actions such as disabling, circumventing, or altering implemented security or privacy controls, or establishing system accounts — including performing system integrity checks, conducting patching operations, or administering cryptographic key management activities — all of which ordinary, non-privileged users are not authorized to perform. In practice, privileged functions typically involve the control, monitoring, or administration of the system and its security measures, and misuse of privileged functions — whether intentional or unintentional, by authorized users or by unauthorized entities — is treated as a serious risk, which is why logging their execution is a standard control mechanism.
Advisory only. A term this product ships is defined by an authority document, not by a search result.
