- Add validated mitre_attack frontmatter to all 754 skills (286 distinct techniques), verified against MITRE ATT&CK v19.1 via the official mitreattack-python library: 0 revoked, deprecated, or invalid IDs - Curate precise per-skill technique IDs for forensics, malware-analysis, threat-intel, and red-team skills (e.g. DCSync -> T1003.006, Kerberoasting -> T1558.003, Pass-the-Ticket -> T1550.003) - Reconcile v19.1 tactic restructuring: Defense Evasion split into Stealth (TA0005) and Defense Impairment (TA0112); revoked T1562.* family and T1070.001/.002 remapped to active equivalents (T1685.*) - Normalize word-split tags across 35 skills (remove filename-derived stopword tags, add semantic cybersecurity tags) - Add api-reference.md for 3 skills that were missing it - Update README ATT&CK section with accurate v19.1 tactic distribution

# Performing SSL/TLS Security Assessment
|
|
|
|
## 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
|
|
|
|
## Steps
|
|
|
|
### 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.
|
|
|
|
## Expected Output
|
|
|
|
JSON report with supported protocols, accepted cipher suites, certificate details, vulnerability results (Heartbleed, ROBOT), and HSTS status.
