Configuration Guide:
-
HTTPS Security Best Practice (I) - SSL/TLS Deployment -
HTTPS Security Best Practices (II) Security Reinforcement -
HTTPS Security Best Practices (III) - Server Software
explain:
-
SNI: Server name indicates that this is a TLS extension that allows servers to deploy multiple certificates on the same IP and port. -
PFS: PFS (perfect forward secure) is completely forward secure. It requires that one key can only be used for one connection. If one key is cracked, the security of other keys will not be affected. -
HPKP: Public key fixation, which is a security mechanism for https websites to prevent attackers from man in the middle attacks using certificates incorrectly issued by CA. -
HSTS: This is a response header used to force the HTTPS protocol to solve the hijacking problem of 301 jump. -
OCSP: Online Certificate Status Protocol. -
OCSP Stapling: OCSP binding transmits the revocation status during TLS handshake to speed up the completion of SSL handshake.
