Summary

  • Implements ApplicationLayerProbe to detect HTTP on TLS ports (fixes Add Property for "Speaks HTTP on TLS Port" #38)
  • Adds SPEAKS_HTTP property to track whether server responds to HTTP requests
  • Integrates with existing application layer detection framework

Implementation Details

  • New probe sends HTTP GET request after successful TLS handshake
  • Detects HTTP by checking for valid HTTP response status codes
  • Merges results with existing application protocols (e.g., from DTLS probe)
  • Follows existing probe patterns and conventions

Changes

  • Added SPEAKS_HTTP to TlsAnalyzedProperty enum
  • Added APPLICATION_LAYER to TlsProbeType enum
  • Created ApplicationLayerProbe class with HTTP detection logic
  • Registered probe in TlsServerScanner
  • Added property to rating influencers XML
  • Added unit tests for the new probe

Test Plan

  • Code compiles successfully
  • Unit tests written and passing
  • Spotless formatting applied
  • Integration testing with real HTTPS servers
  • Verify probe correctly identifies HTTP-speaking TLS services
  • Test with non-HTTP TLS services to ensure no false positives

Closes #38

Add ApplicationLayerProbe for HTTP detection on TLS ports
a9209a0 
- Add new SPEAKS_HTTP property to TlsAnalyzedProperty enum
- Add APPLICATION_LAYER probe type to TlsProbeType enum
- Implement ApplicationLayerProbe that sends HTTP GET request after TLS handshake
- Register new probe in TlsServerScanner probe list
- Add SPEAKS_HTTP property to rating influencers XML
- Add unit tests for ApplicationLayerProbe

This addresses issue #38 to detect when a server speaks HTTP on a TLS port,
which is useful for identifying HTTPS services.
