Summary

SSRF attacks occur when an attacker coaxes a server into returning sensitive information residing on the server itself or in its internal network. To protect against SSRF attacks, Svix recommends a multi-tiered approach to security, including restricting applications' access to only needed internal resources and using subnet filtering, which allows users to whitelist specific IP addresses or subnets to prevent requests to unauthorized resources. The open-source Svix platform provides protection out of the box, but users can also configure this feature to customize their settings, such as disabling SSRF protection entirely if necessary.
