The article describes how to disable 3DES and DES ciphers on the command center.
Instructions
1. Backup transportprovider.conf.
2. Login to GUI of Command Center.
3. Go to Administration >> Change Cipher Settings.

4. Remove the 3DES Ciphers:
In the above screenshot we have : SSL_RSA_WITH_3DES_EDE_CBC_SHA,SSL_DHE_RSA_WITH_3DES_EDE_CBC_SHA,SSL_DHE_DSS_WITH_3DES_EDE_CBC_SHA
5. Save the configuration.
6. Restart the CC Service using following command :
/etc/init.d/NSCCService restart
7. After doing the same verify the changes done under server.xml. We should not see the Ciphers removed.
Server.xml location: opt/citrix/citrix command center/conf/server.xml
In case the Command Center is in High Availability:
Follow the above step from 1 to 5.
6. Stop the CC Service on Primary using following Command :
/etc/init.d/NSCCService stop
7. This will perform a faillover and the other node will become primary.
8. Perform step 1 to 5 on the other node.
9. Stop the CC Service on current Primary Node.
10. This will make other node as Primary again.
Following the above steps we will be able to remove DES ciphers
