IDS signatures disappear on ids viewer

Folks,

I have an IDS 4210, with 4.x running on it. I recetly purchased it and testing it these days.

when i run a port scanner on my network the alarms are generated on the IDS.But, when i come the next day and look at the IDS viewer all the alarms are gone?? is their anyway i can preserve these alarms?

Also, could someone tell me the practical use of "IP LOGGING" Feature of the IDS. Does it enable IDS to collect extra data when it sees an alarm. Can i configure it to start logging when it sees a specific signature. Any feedback would be highly appreciated.

Thanks,

Re: IDS signatures disappear on ids viewer

Hi,

to your first question:

Go to your EventViewer - Views window, press the mouse right key on the proper view (SigNameGroup, e.g.). Choose DataSource from the pop-up menu which appeared. Select the yesterday's archive file to see the older alarms.

Another tuning:

Go to the Device window, choose your IDS device.

Pres right mouse key, choose Properties from pop-up menu.

Change Event Start Time from Latest Alarms (default) to a date in the past. If you don't make this change, the EventViewer only accepts new alarms coning from IDs and omites the older ones.

Read http://www.cisco.com/univercd/cc/td/doc/product/iaabu/csids/csids10/idmiev/swchap6.htm

for more details.

to the second question:

You can configure a signature EventAction parameter to "Log" value to start logging when IDS sees the specific signature.

see http://www.cisco.com/univercd/cc/td/doc/product/iaabu/csids/csids10/idmiev/swchap3.htm#32326

and

for details.
