Fix Recommendation

Configure the Riverbed Optimization System (RiOS) to support TLS version 1.1 as a minimum and preferably TLS version 1.2.

Navigate to the device Management Console.
Navigate to Configure >> Optimization >> Advanced Settings
Select "Add a New Peer Cipher".
Scroll down options list until the following is reached:

"TLSv1.2+FIPS:kRSA+FIPS:!eNULL:!aNULL"

Select that string and a "Rank" of "2".
Click "Add".
Select "Rank 1" "Default" Cipher String.
Click "Remove Selected".
Select "Add a New Client Cipher".
Scroll down options list until the following is reached:

"TLSv1.2+FIPS:kRSA+FIPS:!eNULL:!aNULL"

Select that string and a "Rank" of "2".
Click "Add".
Select "Rank 1" "Default" Cipher String.
Click "Remove Selected".
Select "Add a New Server Cipher".
Scroll down options list until the following is reached:

"TLSv1.2+FIPS:kRSA+FIPS:!eNULL:!aNULL"

Select that string and a "Rank" of "2".
Click "Add".
Select "Rank 1" "Default" Cipher String.
Click "Remove Selected".

Navigate to the top of the web page and click "Save" to save these settings permanently.

Check Contents

Verify that the Riverbed Optimization System (RiOS) is configured to support TLS version 1.1 as a minimum and preferably TLS version 1.2.

Navigate to the device Management Console.
Navigate to Configure >> Optimization >> Advanced.
Verify that "Peer Ciphers:" "Rank 1" contains the following string:

"TLSv1.2+FIPS:kRSA+FIPS:!eNULL:!aNULL"

Verify that "Client Ciphers:" "Rank 1" contains the following string:

"TLSv1.2+FIPS:kRSA+FIPS:!eNULL:!aNULL"

Verify that "Server Ciphers:" "Rank 1" contains the following string:

"TLSv1.2+FIPS:kRSA+FIPS:!eNULL:!aNULL"

If any of the above Ciphers contains strings or groups other than what is listed, this is a finding.
