# Performing SSL/TLS Security Assessment

## Quick Start

```bash
# testssl.sh
testssl.sh https://target.com
# sslyze
sslyze --regular https://target.com
```

## Overview

Assess SSL/TLS server configurations using sslyze, a fast Python-based scanning library. This skill covers evaluating supported protocol versions (SSLv2/3, TLS 1.0-1.3), cipher suite strength, certificate chain validation, HSTS enforcement, OCSP stapling, and scanning for known vulnerabilities including Heartbleed, ROBOT, and session renegotiation weaknesses.


## When to Use

- When conducting security assessments that involve performing ssl tls security assessment
- When following incident response procedures for related security events
- When performing scheduled security testing or auditing activities
- When validating security controls through hands-on testing

## Prerequisites

- Python 3.9+ with `sslyze` library (pip install sslyze)
- Network access to target HTTPS servers on port 443
- Understanding of TLS protocol versions and cipher suite classifications

## Workflow
### Step 1: Configure Server Scan
Create ServerScanRequest with ServerNetworkLocation specifying target hostname and port.

### Step 2: Execute TLS Scan
Use sslyze Scanner to queue and execute scans for all TLS check commands concurrently.

### Step 3: Analyze Results
Evaluate accepted cipher suites, certificate validity, protocol versions, and vulnerability scan results.

### Step 4: Generate Security Report
Produce a JSON report with compliance findings and remediation recommendations.

## Output Format

JSON report with supported protocols, accepted cipher suites, certificate details, vulnerability results (Heartbleed, ROBOT), and HSTS status.

## Validation Criteria

A successful discovery of this vulnerability class must demonstrate:

- [ ] POC reproducible against fresh target instance (timestamp documented)
- [ ] Impact scope quantified (data leaked / privilege gained / RCE achieved)
- [ ] CVSS or business risk score assigned
- [ ] Authorization scope documented (B SRC vs target, A 项目 vs 全量)
- [ ] No destructive side effects (if RCE, sandboxed proof preferred)
- [ ] Affected endpoint clearly identified with full URL/request

If any of these cannot be demonstrated, treat the finding as inconclusive and run `111-fp-check` for cross-verification.

## Workflow

1. **Recon** — Identify the target endpoint via `96-osint-methodology` or `009-osint-with-spiderfoot`
2. **Fingerprint** — Confirm component/version using `01-component-nday` or Burp Suite passive detection
3. **Probe** — Send payload variations matching the vulnerability class
4. **Verify** — Run `111-fp-check` to confirm with second tool
5. **Document** — Fill report template (project-pentest / cnvd-common / edusrc / butian)
6. **Submit** — Manual submission (never auto-submit)
## Tools & Systems

- **Burp Suite Pro / Community** — Intercepting proxy, scanner, and Repeater for manual testing
- **OWASP ZAP** — Open-source alternative to Burp with active scanner
- **sqlmap** — Automated SQL injection detection (for hunt-sqli)
- **Nuclei** — Template-based vulnerability scanner
- **ffuf** — Fast web fuzzer for endpoint discovery
- **curl / wget** — Manual HTTP request crafting
- **httpx** — HTTP probing and fingerprinting

Run all tools with `-rate-limit 20` to avoid OPSEC issues. For deeper investigation, prefer manual testing with Burp over automated scanners (lower false-positive rate).


## Advanced Techniques

### Chained Vulnerability Exploitation
Combine multiple low-severity findings (open redirect + cookie theft + session hijacking) to demonstrate high-impact chains in reporting.

### WAF Evasion Patterns
Use case variations, encoding (URL, double-URL, Unicode), chunked transfer, and parameter pollution to bypass WAF/IDS during testing.
