PKI: Public Key Infrastructure in Cybersecurity
Never 'pi-KEY'.
PKI stands for Public Key Infrastructure. Public key infrastructure is the set of roles, policies, hardware, software, and procedures needed to create, manage, distribute, and revoke digital certificates. PKI enables encrypted communication and identity verification across networks.
How PKI Is Used in Cybersecurity
Security engineers manage PKI to issue TLS certificates for web servers, VPNs, and internal services. Architects design certificate hierarchies with root and intermediate CAs. Incident responders investigate certificate-based attacks like man-in-the-middle interceptions.
