Episode 30 — Lock down web applications and exposed APIs
This episode focuses on web applications and APIs because payment environments increasingly rely on browser-based flows and service-to-service integrations, and the ISA exam often tests how you assess exposure, authentication strength, and input handling under real constraints. You’ll define what it means for an application or API to be “exposed,” including public endpoints, partner integrations, internal APIs reachable from shared networks, and cloud-managed gateways that are easy to misconfigure. We’ll discuss core protection concepts such as strong authentication, authorization checks, session management, rate limiting, and input validation, then connect them to evidence you can collect, like configuration settings, access logs, test results, and documented secure coding standards. You’ll work through scenarios such as an e-commerce checkout page with third-party scripts, an API that trusts client-side authorization, and a service that leaks data through verbose error messages, and you’ll learn best practices for hardening while preserving reliability. By the end, you’ll be able to explain how web and API controls reduce risk and how to validate those controls in a way that supports both exam answers and real assessments.
