Resolution: According to TLS/SSL specification, when a SSL client first negotiates a SSL connection with its peer (the server,in the language of TLS specification), the server may choose to return an assigned session ID to the client.

Session hijacking - Wikipedia Methods to prevent session hijacking include: Encryption of the data traffic passed between the parties by using SSL/TLS; in particular the session key (though ideally all traffic for the entire session). This technique is widely relied-upon by web-based banks and other e-commerce services, because it completely prevents sniffing-style attacks. EMS TLS extension enforcement causing capacity issue In ADC Transport Layer Security (TLS) protocol for any mechanism that relies on the master secret for authentication, an example being session resumption. To prevent against any vulnerabilities for “man-in-the-middle” attack, in the October 2019 patch, Microsoft enabled the EMS extension by default for all Microsoft clients and servers. diffie hellman - How is session key generated for TLS A problem with this scheme is that the encrypted pre-master secret can be stored by the attacker - together with the rest of the TLS session. The attacker can then try and find the private key value. Once that is found all the data of that particular session and all other sessions protected with the private key can be decrypted.

This negotiated version is the one that is used for the connection. If the server doesn't support the version presented by the client, the server message will specify the highest version it can use.

TLS Caching Explained on BIG-IP DevCentral For Client SSL profile, BIG-IP uses Session ID or Session Ticket to look up TLS session entries in local SSL cache. If Session ID or Session Ticket is changed, it is a cache miss. For Server SSL profile, BIG-IP uses back end server's IP address and destination port for the lookup in order to find corresponding Session ID or Session Ticket to be Session Management - OWASP Transport Layer Security¶ In order to protect the session ID exchange from active eavesdropping and passive disclosure in the network traffic, it is essential to use an encrypted HTTPS (TLS) connection for the entire web session, not only for the authentication process where the user credentials are exchanged.
