The IP address 169.254.169.254 hosts the AWS Instance Metadata Service (IMDS), a critical endpoint for retrieving IAM security credentials from EC2 instances. Exploiting this path, specifically through Server-Side Request Forgery (SSRF), allows unauthorized access to temporary credentials and risks full infrastructure compromise. To mitigate these risks, it is recommended to adopt IMDSv2, which introduces token-based authentication to prevent SSRF vulnerabilities.

This is the most effective defense. Unlike the original service (IMDSv1), requires a "Session Token." An attacker cannot simply "fetch" the URL; they must first perform a PUT request to create a token, which most SSRF vulnerabilities cannot do. Action: Force "IMDSv2 Required" on all EC2 instances. 2.
