Glimpse of a real-world DiD approach
Having explored a myriad of concepts across various security domains and learned how to construct a layered defense strategy, let’s now put that knowledge into practice by designing defensive controls against one of the most common vulnerabilities found in modern web applications.
Threat
Server-side request forgery (SSRF) occurs when an attacker takes advantage of a server-side flaw to coerce it to fetch resources and access or manipulate information locally in the server context that the attacker should not have access to [10].
SSRF allows attackers to manipulate a web application into sending unauthorized requests from the server. This exploit typically occurs when an application processes user-supplied URLs to fetch resources. Attackers can abuse this vulnerability to access internal systems, pivot to other parts of the network, or execute attacks against different servers, bypassing access controls and posing significant security...
