Welcome to the Server-Side Request Forgery course. Server-Side Request Forgery (SSRF) is increasingly relevant in microservices, cloud-native systems, and other distributed application architectures. SSRF exploits the way an application makes outbound connections. The more outbound connections an application can initiate, the more important it becomes to validate, restrict, and monitor those requests. This course explains how SSRF vulnerabilities are exploited, what they look like in source code, and the corresponding mitigation strategies. The course uses .NET source code for illustration, but the concepts can be applied to any programming language.
