Cipher Suits

Hi,

UTM latest version. Email: TLS1.2 active.

Ran a scan using Hardenize and the result is:

TLS v1.2
Unknown preference

TLS_RSA_WITH_AES_128_CBC_SHA 128 bits
TLS_RSA_WITH_AES_256_CBC_SHA 256 bits
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA 128 bits (ECDHE 256 bits)
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA 256 bits (ECDHE 256 bits)
TLS_ECDH_anon_WITH_AES_128_CBC_SHA 128 bits
TLS_ECDH_anon_WITH_AES_256_CBC_SHA 256 bits
TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 128 bits (ECDHE 256 bits)
TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 256 bits (ECDHE 256 bits)
TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 128 bits (ECDHE 256 bits)
TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 256 bits (ECDHE 256 bits)
TLS_DHE_RSA_WITH_AES_128_CBC_SHA 128 bits (DHE 2048 bits)
TLS_DHE_RSA_WITH_AES_256_CBC_SHA 256 bits (DHE 2048 bits)
TLS_RSA_WITH_AES_128_CBC_SHA256 128 bits
TLS_RSA_WITH_AES_256_CBC_SHA256 256 bits
TLS_RSA_WITH_CAMELLIA_128_CBC_SHA 128 bits
TLS_DHE_RSA_WITH_CAMELLIA_128_CBC_SHA 128 bits (DHE 2048 bits)
TLS_DHE_RSA_WITH_AES_128_CBC_SHA256 128 bits (DHE 2048 bits)
TLS_DHE_RSA_WITH_AES_256_CBC_SHA256 256 bits (DHE 2048 bits)
TLS_RSA_WITH_CAMELLIA_256_CBC_SHA 256 bits
TLS_DHE_RSA_WITH_CAMELLIA_256_CBC_SHA 256 bits (DHE 2048 bits)
TLS_RSA_WITH_AES_128_GCM_SHA256 128 bits
TLS_RSA_WITH_AES_256_GCM_SHA384 256 bits
TLS_DHE_RSA_WITH_AES_128_GCM_SHA256 128 bits (DHE 2048 bits)
TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 256 bits (DHE 2048 bits)

 Where do these 2 come from:
TLS_ECDH_anon_WITH_AES_128_CBC_SHA 128 bits
TLS_ECDH_anon_WITH_AES_256_CBC_SHA 256 bits

This is what I see in the reversproxy.conf:

SSLProtocol -all +TLSv1.2
SSLCipherSuite ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:RSA+AESGCM:RSA+AES:!aNULL:!MD5:!DSS

Can I get rid of these anon-suits?

Thanks

  • Hallo and welcome to the UTM Community!

    You might try adding !anon to the end of the SSLCipherSuite line - that's a guess.  Let us know if Sophos Support has the answer.

    Cheers - Bob
