SEC522: Application Security: Securing Web Applications, APIs, and Microservices - Live Online

HTTP stopped being a website protocol a long time ago. It is now the connective tissue between cloud services, microservices, API gateways, and AI inference endpoints, and a flaw in one of those paths rarely stays contained to one application.

SEC522 teaches defense across that whole surface, virtually in real-time, with your questions answered as they come up. The lab environment is a running application rather than a slide deck: you attack it, defend it, then see what your control blocked. The course is programming-language agnostic, so the patterns hold whether your stack is Java, Python, .NET, or something newer.

During the Week, You'll Work Through

  • 17 hands-on labs
  • A competitive Defend the Flag capstone
  • SQL injection, XSS, CSRF, Unicode, and file upload handling
  • OAuth and access control, session fixation, and TLS traffic inspection
  • Content Security Policy, clickjacking, and cross-domain request defenses
  • GraphQL, API gateway, and JSON security exercises
  • Securing AI Endpoints and APIs

Securing AI Endpoints and APIs

The course closes its API and microservices section with securing AI components inside modern applications, including how AI inference endpoints inherit the same weaknesses as anything else built on HTTP. You’ll get 30 CPE credits for this course, and it’s aligned to the GIAC Certified Web Application Defender (GWEB) certification.

Who Should Take This Course?

Application security analysts and managers, application architects, technical leads of development teams, auditors who need to evaluate web defenses rather than just check for them, penetration testers who want the defensive side, and teams working under PCI DSS requirements. A basic working knowledge of HTML, JavaScript, and SQL is assumed.
