 While scanning the ports’ (like 8443, 5000, 8200) vulnerabilities, such message is returned

"HSTS Missing From HTTPS Server"


All the services (8443: K8s apiserver, 8200: vault, 5000: local registry) are https-only services that don’t have an http listener and with that, so no need to set HSTS.

Localhost:5000 is the local docker image registry – in newer versions of CDF like 2019.11, it is constrained to TLS1.2 (standard list of strong ciphers)
