SSL/TLS Analysis

The SSL/TLS Analysis feature examines your website’s secure connection implementation, providing detailed insights into certificate configuration, protocol support, and potential security vulnerabilities.

Key Features

Section titled “Key Features”

SiteOne Crawler’s SSL/TLS Analysis offers:

  1. Certificate Validation: Checks certificate validity, expiration dates, and trust chain
  2. Protocol Support: Identifies supported SSL/TLS protocol versions
  3. Cipher Security: Evaluates the security of supported cipher suites
  4. Security Features: Checks for modern security features like OCSP stapling and HTTP Strict Transport
  5. Configuration Best Practices: Validates against current SSL/TLS best practices

Certificate Information Table

Section titled “Certificate Information Table”

The analyzer generates a detailed certificate information table:

SSL/TLS Property               Value
------------------------------------
Protocol Version               TLS 1.3
Certificate Issuer             Let's Encrypt Authority X3
Certificate Expiry             2024-06-15 (Valid: 82 days)
Certificate SANs               example.com, www.example.com
OCSP Stapling                  Enabled
HTTP Strict Transport          Enabled (max-age=31536000)
TLS Cipher Suite               ECDHE-RSA-AES256-GCM-SHA384

Comprehensive Security Assessment

Section titled “Comprehensive Security Assessment”

The analysis provides a comprehensive assessment of SSL/TLS security:

Certificate Details

Section titled “Certificate Details”
  • Validity Period: Confirmation that certificate is current and not expired
  • Subject Alternative Names (SANs): Verification of all domains covered by the certificate
  • Certificate Authority: Information about the issuing certificate authority
  • Certification Path: Validation of the complete certificate chain

Protocol Security

Section titled “Protocol Security”
  • Supported Protocols: Identification of supported SSL/TLS versions (TLS 1.2, TLS 1.3, etc.)
  • Insecure Protocols: Detection of deprecated protocols (SSL 3.0, TLS 1.0, TLS 1.1)
  • Forward Secrecy: Verification of support for Perfect Forward Secrecy
  • Cipher Suites: Analysis of supported cipher suites and their security levels

Implementation Features

Section titled “Implementation Features”
  • OCSP Stapling: Verification of OCSP stapling implementation
  • HSTS: Validation of HTTP Strict Transport Security configuration
  • Certificate Transparency: Check for Certificate Transparency compliance
  • Key Type and Size: Assessment of key type (RSA, ECDSA) and key size

Security Recommendations

Section titled “Security Recommendations”

Based on the analysis, the crawler provides actionable SSL/TLS recommendations:

  • Protocol Updates: Suggestions to disable outdated protocols
  • Cipher Prioritization: Recommendations for secure cipher suite configuration
  • Certificate Improvements: Advice on certificate implementation and renewal
  • Security Header Configuration: Guidance on related security headers

Implementation Details

Section titled “Implementation Details”

The SSL/TLS Analyzer works by:

  1. Establishing a secure connection to the website
  2. Retrieving and parsing certificate information
  3. Analyzing protocol and cipher support
  4. Checking for modern security features
  5. Validating against current best practices

Real-World Benefits

Section titled “Real-World Benefits”

The SSL/TLS Analysis provides several practical benefits:

  • Security Validation: Ensure your SSL/TLS implementation meets current security standards
  • Expiration Monitoring: Get advance notice of certificate expiration dates
  • Vulnerability Detection: Identify potentially insecure configurations
  • Compliance Verification: Validate against security requirements and best practices
  • Trust Indicators: Ensure your site meets the requirements for browser security indicators

💡Further Development Ideas

Section titled “💡Further Development Ideas”

Future enhancements to the SSL/TLS Analysis could include:

  • Protocol Negotiation Analysis: Deeper inspection of protocol negotiation behavior
  • Client Simulation: Testing with different client capabilities
  • Certificate Revocation Checking: More comprehensive revocation status validation
  • CAA Records: Verification of Certificate Authority Authorization DNS records
  • CT Log Monitoring: Integration with Certificate Transparency log monitoring
  • Scoring System: Standardized security score based on SSL/TLS implementation
