Understanding Server Side Request Forgery (SSRF).pptx

Discover the intricacies of Server-Side Request Forgery (SSRF), a critical vulnerability that allows attackers to trick a server into making unauthorized requests. This comprehensive presentation explains the core concepts of SSRF, its potential impact on web applications, and how attackers can exploit it to access sensitive internal systems or services. Dive into real-world examples of SSRF attacks, learn about various attack vectors, and explore the most effective mitigation techniques to secure your applications. This presentation is perfect for cybersecurity professionals, penetration testers, developers, and anyone interested in strengthening their knowledge of web security and protecting systems from SSRF threats.
