Each rewritten description now states both what the skill does (concrete capability, named tools/artifacts) and an explicit when-to-use trigger, improving agent discovery/activation. Grounded in each skill's own body; changes confined to the `description` field only (bodies and all other frontmatter untouched). Produced by a gated audit->rewrite->recheck loop (548 -> 0 flagged) with a sampled anti-invention check (0 ungrounded). Schema: 817/817 pass. Framework-ID gate: 0 defects.

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
sslyzelibrary (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.
