Certificate Authority.
A Certificate Authority is a trusted entity that issues, signs, and revokes digital certificates. CAs verify the identity of certificate requestors before issuing certificates. Root CAs are pre-trusted by operating systems and browsers. Intermediate CAs, signed by root CAs, issue most end-entity certificates in practice.
Compromised CAs are among the most severe security incidents possible, as they undermine trust for millions of connections. Security engineers manage internal CAs for enterprise environments. GRC analysts audit CA practices against standards like WebTrust. Understanding CA trust chains helps analysts detect fraudulent certificates in the wild.
