Physically installing the Sensors

Installing McAfee

Network Security Sensors (Sensors) at this point may seem premature.

After all, you will no doubt perform tests once the failover pair has been configured. The

logic here is to confirm connectivity and proper scanning with as few variables as possible.

If basic connectivity and scanning prove to be fine now, but fail after configuring the

failover pair, you at least know the issue is specific to the failover pair.

Ideally, you should test each Sensor individually. This includes, if need be, manually failing

over the Primary path, so traffic will flow across the Secondary path.

You can use common utilities like

Ping and Traceroute (tracert.exe on Windows) to test basic

connectivity. You can also look at the statistics from the Threat Analyzer for each Sensor

port to confirm that traffic is properly flowing through it.

Note: For step-by-step procedures on verifying how to verify traffic is flowing

through the Sensor, see the System Status Monitoring Guide.

An easy and benign way to confirm that Network Security Platform is scanning for exploits

is to trigger a FTP directory traversal signature.
