The protocols and/or ciphers used by Symantec LiveUpdate Administrator (LUA) need to be customized.
First, change the LUA communication protocol to HTTPS. Next, follow these steps to adjust the protocols and ciphers used in server.xml and java.security.
To modify server.xml
To modify java.security
Restart the LUA Apache Tomcat service. Log in to the LUA to confirm it's still accessible.
If the wrong combination of protocol and ciphers are entered when editing server.xml and java.security, the LUA console may not load. Revert the server.xml and java.security to the backed up files and make any adjustments necessary.
