* Avoid RC4. RC4 has never been approved by CSE for the protection of GC information. Modern browsers no longer support RC4-based cipher suites, and servers should no longer need to be configured to support RC4.

* Servers should be configured to ensure that the server and client ephemeral key-pairs (see PFS below) satisfy the key length requirements specified in ITSP.40.111.

In the following table, the first column lists all ciphers which satisfy the cryptographic guidance provided in ITSP.40.111. It is recommended that servers be configured to exclusively support the cipher suites listed in the second column, preferring them in the listed order:
