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
