I am working today at a Client Site where I installed several months ago a Cisco IPS 4240 Sensor. The Sensor is currently running Version 6.0(3)E1.
I am not certain how to proceed with respect to signature updates on this box.
Under signature definition, it lists the following:
Signature Update S291.0 2007-06-18
I have noticed on the Security Software Page for IPS that the latest Signature File is S336. Should I install this on the IPS? In order to perform this, will it take down the IPS unit?
Also, there are several Management applications listed under the "Network IPS/IDS Management/Monitoring Software" heading, including: IME, IPC MC, and ICS. I am already using IDM as well as IEV respectively to Configure/ Monitor and then IEV to Alarm on certain Events. What are IME, IPC MC, and ICS and how are they different from IDM and IEV??
