HTTP/2 and HTTP/3 Support

Phase 2config mgmtWSTG-CONF

Description

Checks whether the site is served over HTTPS (a prerequisite for HTTP/2) and whether HTTP/3 is advertised via the Alt-Svc response header.

Security Impact

HTTP/2 provides multiplexing and header compression that reduces attack surface from TCP connection flooding. HTTP/3 over QUIC adds connection migration and improved handshake security.
