Server-Side Request Forgery (SSRF) happens when an attacker tricks your server into making unauthorized requests.
Instead of hitting your public API, the attacker forces your server to talk to internal systems. This gives them access to things they should never see.
Common targets include:
- Cloud metadata endpoints
- Internal services
- Localhost resources
Protect your systems with these steps:
- Use network segmentation to isolate sensitive services.
- Implement allow lists for outgoing requests.
- Validate all user-provided URLs strictly.
Building secure systems requires a disciplined approach. Follow these principles to avoid common mistakes:
Keep it simple. Complexity causes bugs and security holes. Build a working foundation first. Add complexity only when you have a real reason.
Measure everything. Do not guess where your risks are. Use data to find bottlenecks and security gaps.
Automate your defenses. Manual checks fail. Use automated testing to catch errors before they reach production.
Test for failure. Write tests for normal use and edge cases. Ensure your system fails safely when it meets unexpected input.
Monitor in production. Watch your error rates and resource use. Set up alerts so you know when something goes wrong immediately.
Complexity is the enemy of reliability. Focus on small, manageable pieces. Break large problems down so you can test and deploy them independently.
Start small. Pick one part of your system to audit this week. Fix one gap. Learn from the process.
