PKI

Cryptography

Acronym for Public Key Infrastructure—the trust framework for digital certificates.

PKI stands for Public Key Infrastructure. See 'Public Key Infrastructure' for the full definition. PKI certificate management is increasingly important as more services require trusted certificates.

Why It Matters

The DSC Perspective:

PKI issues affect everyone—expired certificates cause outages, mismanaged certificates create security risks. Ensure certificate lifecycle management is part of your operational processes.
