One of your remote Security Gateway’s suddenly stops sending logs, and you cannot install the Security Policy on the Gateway. All other remote Security Gateways are logging normally to the Security Management Server, and Policy installation is not affected. When you click the Test SIC status button in the problematic Gateway object you receive an error message. What is the problem?
A.
There is no connection between the Security Management Server and the remote Gateway.
Rules or routing may block the connection.
B.
The remote Gateway’s IP address has changed, which invalidates the SIC Certificate.
C.
The time on the Security Management Server’s clock has changed, which invalidates the remote Gateway’s Certificate.
D.
The Internal Certificate Authority for the Security Management Server object has been removed from objects_5_0.C.
