Always prefer cipher suites with PFS property over the non-PFS ones. Note that performance considerations implies preferring Ephemeral Elliptic-curve Diffie–Hellman over Ephemeral Diffie-Hellman.
Remove the cipher suite from the list of cipher suites supported by your server or at least set the cipher suite order explicitly and any cipher suite modes be preferred over ciphers suites with CBC modes.
Encryption Key Size
The symmetric key withkey size more than 128 bits as it is should be according to National Institute of Standards and Technology so it is not vulnerable to preimage attack and it cannreliably prove that message came from the stated sender (its authenticity) and has not been changed, so connection is not open for a man-in-the-middle attack.
