Whitelist scanner IP address

Contributor

We have a regular vulnerability scan against the workstations and it keeps triggering incidents as it trying to login with known, easy to guess, passwords. Is there a way to whitelist connections from a private IP so we don't MDATP alerts during scans?

I should also mention that this scan triggers an "Internal brute-force attack" incident that doesn't have an IOC attached to it so it is not possible to create a suppression rule. Since this is an internal IP, I cannot add it to the list of custom IOCs either (though not sure how would that help if the incident doesn't include it as an IOC). 

 

The best I can do is to suppress this type of alert completely but that would leave the computers open to real internal brute-force attacks.

Have a try of this article

i was looking for a kind of ActiveList to exclude our scanners too and it works great.
