Logs for used cipher suites

Hello,

We are using istio ingress gateway with AKS and would like to know how could I get logs for which ciphers are being used by clients. I want logs on server side. Security tests have detected some week ciphers and wants to see if they are being used. Below is list of week ciphers:

  • TLS_RSA_WITH_AES_128_CBC_SHA (0x002F)
  • TLS_RSA_WITH_AES_256_CBC_SHA (0x0035)
  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (0xC013)
  • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA (0xC014)

Thank you in advance.
