Episode 48 — Design VPN and IPsec Strategies That Preserve Identity, Integrity, and Scale
This episode covers how to design VPN and IPsec solutions that do more than create encrypted tunnels, which is directly relevant to ISSAP because exam questions often test identity binding, access scope, and operational scalability. You’ll learn how to choose between remote access and site-to-site designs, how to align authentication with enterprise identity, and how to prevent broad network access when the true need is limited application access. We’ll discuss practical design topics like split tunneling decisions, per-user versus per-device authentication, certificate lifecycle management, and routing and segmentation that preserves least privilege. Examples include securing partner connectivity, protecting administrative access to management networks, and designing high availability so a VPN outage does not become an incident-driven control bypass. Troubleshooting considerations include brittle certificate processes that cause widespread failures, misconfigured crypto suites that break interoperability, routing mistakes that create hidden trust paths, and tunnel sprawl that makes monitoring and incident response harder than it needs to be.
