What is server info disclosure?
HTTP headers like Server and X-Powered-By can reveal software and version details. Attackers use these to target known vulnerabilities.
How to minimize exposure
- Strip or generalize Server/X-Powered-By
- Avoid leaking framework versions
- Harden error pages and stack traces
Examples (good vs bad)
Bad: Server: nginx/1.16.1, X-Powered-By: Express
Better: Server: cloud, no X-Powered-By
Tool-specific questions
Is hiding versions security by obscurity?
Can CDNs override these headers?
