Episode 45 — Public Key Infrastructure — Concepts and Cloud Use Cases

In this episode, we explore the architecture and functions of Public Key Infrastructure (PKI), which supports secure communications through encryption, authentication, and digital signatures. We explain the components, including certificate authorities, registration authorities, and key pairs, and how they work together to establish trust in a cloud environment. PKI underpins many critical services, from securing APIs to enabling VPN access.We also discuss cloud-specific PKI considerations, such as integrating with managed certificate services, automating renewals, and securing private keys in hardware security modules. In the Cloud+ exam, PKI-related questions often appear in the security domain, requiring both conceptual knowledge and practical application skills. Produced by BareMetalCyber.com, where more prepcasts, books, and PKI deployment resources are available.
