Information in this document applies to any platform.
After some PCI Security scan, we are asked to do this for our Infiniband Switches in our X5-2 Quarter rack :
The server-side TLS endpoint's configuration should be updated to allow only TLSv1.2 connections with cipher suites that use:
• Ephemeral Diffie-Hellman for key exchange (optionally, allow RSA for key exchange if necessary for supporting some clients)
• Block ciphers with key lengths of at least 128 bits (AES-128 and AES-256)
• Block ciphers in GCM mode.
Note: If CBC mode must be allowed for supporting some clients, use only CBC mode cipher suites that use the SHA2 family of hash functions (SHA256, SHA384, SHA512) Note that all modern browsers support TLSv1.2.
