Information
This requirement requires the use of secure protocols instead of their unsecured counterparts, such as SSH instead of telnet, SCP instead of FTP, and HTTPS instead of HTTP. If unsecured protocols (lacking cryptographic mechanisms) are used for sessions, the contents of those sessions will be susceptible to eavesdropping, potentially putting sensitive data (including administrator passwords) at risk of compromise and potentially allowing hijacking of maintenance sessions.
Solution
Configure the Symantec ProxySG to use only AES ciphers for nonlocal maintenance and diagnostic communications.
1. Log on to the CLI via SSH.
2. Type 'enable', enter the enable password.
3. Type 'configure terminal' and press 'Enter'.
4. Type 'management-services' and press 'Enter', type 'edit HTTPS-Console' and press 'Enter'.
5. Type 'view' to display the list of configured cipher suites.
6. Type 'attribute cipher-suite' followed by a space-delimited list of only cipher suites from step 5 containing AES and press 'Enter'.
