Please use the following steps to improve security of connection to AhsayCBS (Strong Cipher, TLS protocol and PFS).

To change the TLS setting:

  1. Go to C:\Program Files\AhsayCBS\conf
  2. Open the server.xml file with a text editor.
  3. Search for the line protocols="TLSv1+TLSv1.1+TLSv1.2"
  4. Change it to protocols="TLSv1.2"
  5. Save the changes to the server.xml file.


To change the cipher settings:

  1. Go to C:\Program Files\AhsayCBS\conf
  2. Open the server.xml file with a text editor.
  3. Search for the line ciphers="HIGH:!aNULL:!MD5"
    • Option 1 - For AhsayCBS server with version 7 and 8 backup clients
      • Change it to ciphers="TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256"
    • Option 2 - For AhsayCBS server with version 8 backup clients only (DO NOT use this option if there is version 7 AhsayOBM / ACB client connecting to your CBS)
      • Change it to ciphers="TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_CHACHA20_POLY1305_SHA256"
  4. Save the changes to the server.xml file.
