Correlation Rule Not Firing Properly

Jump to solution

Hi,

I am trying to set up a rule (and alarm) for detecting admins off business activity.

it should fire when-

1. Sunday to Thursday authentication succeeded between midnight and 6 AM

OR

2. Friday and Saturday authentication succeeded

for some reason it fires even when it shouldn't. can someone help with detecting the problem?

could not follow McAfee documentation instructions regarding "correlation details" in order to track rule activity because I couldn't locate where exactly this information relies.

attached a screenshot

I would take a look at the built in rules and possibly copy and just modify them.  There are rules for off-hours that would be good examples.  

Note: Hours are based on GMT, not local timezone.  Take that into consideration.

On your rules, if you are using signature ID, it is not necessary to identify WMI data source and Normalization.  The signature ID is specific enough for the correlation.

Is the Time of Day filter in the first match component properly created?

I do not see an End time. I only see a Start time of 00:00 followed by a hyphen.
