Protocol HTTPS (TLS)

Transport Layer Security (TLS) is a secure data transfer protocol that creates secure communication to leverage higher privacy. Widely used on the Internet, it is the successor of the ancient SSL. Several versions of the protocol are used in applications and services, TLS 1.3 is the most recent, but TLS 1.2 is very common too. Many protocols rely on TLS, for instance, the HTTPS (Hypertext Transfer Protocol Secure) is a security layer over the unencrypted HTTP, but several e-mail protocols (eg: IMAPS, SMTPS, POP3S) use as well to get a secure connection.

Weak Public Key Revocation Check (OCSP stapling not supported)
Server does not support revocation check mechanism Online Certificate Status Protocol (OCSP) stapling[527][528][529][530][531]. Revocation check mechanisms of X.509 public key[493][494][495][496][497] certificates have many flaws [518][519][520][521] and now, the only practically working and used vendor independent mechanisms is OCSP stapling.Without using a certificate revocation check mechanism a client applications (eg: browser, email client, ...), cannot determine whether X.509 public key the server provides still valid or it has already been revoked by the issuer of the certificate. Without this information it cannot be reliably proved that message caomes from the stated sender (its authenticity) or it has been changed, so connections could be open for a man-in-the-middle attack[61].
Always chose certificate authority[88][89][90]s which support Online Certificate Status Protocol (OCSP)[522][523][524][525][526]. Prefer server implementations which support Online Certificate Status Protocol (OCSP) stapling[527][528][529][530][531] or use a proxy application make up for this shortcomings.
