# Pentest Config Hardening

## Purpose
Shannon checks only 2 of 14 WSTG-CONF items. The remaining 12 are "low-hanging fruit" findings expected in every professional pentest report — straightforward to test systematically.

## Prerequisites

### Authorization Requirements
- **Written authorization** with infrastructure testing scope
- **Target URL list** for all web-facing endpoints
- **CDN/WAF awareness** — some headers may be set by infrastructure, not application

### Environment Setup
- testssl.sh for comprehensive TLS analysis
- nmap with ssl-enum-ciphers script
- curl for manual header inspection
- nuclei with misconfig templates

## Core Workflow
1. **HTTP Security Headers**: Audit HSTS (+ preload), CSP policy analysis, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy, CORP/COEP/COOP (WSTG-CONF-07/14).
2. **TLS Configuration**: Protocol versions (TLS 1.0/1.1 deprecation), cipher suite strength, certificate validity, HSTS preload status, certificate transparency.
3. **HTTP Method Handling**: OPTIONS enumeration, PUT/DELETE on static resources, TRACE for XST, method override headers (WSTG-CONF-06).
4. **Infrastructure Exposure**: Admin interfaces (WSTG-CONF-05), default credentials on management consoles, exposed monitoring endpoints (/metrics, /health, /debug).
5. **Cloud Storage Misconfig**: Public S3 buckets, Azure blob containers, GCP storage referenced in app code or responses (WSTG-CONF-11).
6. **CSP Bypass Analysis**: unsafe-inline, unsafe-eval, overly broad source lists, JSONP on allowed domains, missing base-uri (WSTG-CONF-12).
7. **Cookie Security**: Secure flag, HttpOnly flag, SameSite attribute, cookie scope, session cookie entropy.
