As part of the new best practices in hardening server communications I need to deny TLS 1.0 on the web server, before doing so I wish to identify the number of clients who connect with this level of encryption.
Therefore I would like to know how to filter incoming communications with different encryption methods like TLS 1. 0, 1. 1 and 1. 2. If there is a different method to identify or quantify these communications which will be easier than whireshark I would be glad to hear about it.
