Episode 26 — Control external access by limiting public endpoints and enforcing private connectivity
External access design determines whether attackers can reach your services at all, so this episode connects network exposure decisions to governance outcomes and exam-ready reasoning. You’ll define public endpoints, private connectivity, and the operational motivations that lead teams to expose services, then evaluate those choices through risk, blast radius, and monitoring needs. We’ll cover best practices such as defaulting to private access for admin and sensitive data paths, using controlled ingress points, and designing connectivity that supports segmentation and identity-based authorization. You’ll also troubleshoot common pitfalls like accidental internet exposure, inconsistent DNS and routing that bypasses intended controls, and “temporary” public access added during troubleshooting that never gets removed. The outcome is an actionable approach for reducing exposure without blocking legitimate business workflows.
