+# Reverse Proxy Fingerprint Hardening Plan
+
+Date: 2026-04-07
+Scope: Public FQDNs listed in `results/targets.txt`.
+
+## Required hardening actions
+
+1. Disable server tokens/version banners on nginx/Apache/other reverse proxies.
+2. Remove or minimize `X-Powered-By` and framework-identifying headers.
+3. Standardize generic error pages for unauthenticated endpoints; remove app-specific stack hints.
+4. Validate with:
+   - `whatweb`
+   - `nmap --script http-headers`
+5. Track unavoidable disclosures (for example, app title in HTML) as accepted risk.

+## Command set to run per host
+
+```bash
+whatweb https://<fqdn>
+whatweb http://<fqdn>
+nmap -Pn -p 80,443 --script http-headers <fqdn>
+```
+
+## Environment note (this run)
+
+`whatweb` and `nmap` are not installed in the current execution environment, so live validation was not completed in this run.
+
+## Accepted-risk register template
+
+| FQDN | Unavoidable disclosure | Justification | Owner | Review date |
+|---|---|---|---|---|
+| <fqdn> | App title / product branding | Required for user navigation and SSO trust context | Security + App owner | 2026-07-07 |
