SEC - PUA exceptions not working?

Louis-M

We constantly have warnings about remcomsvc.exe.

We know the software so it's a bit of a false positive for us. So to save alerts, we placed exceptions under antivirus (C:\Windows\System32\RemComSvc.exe) and also authorized the PUA RemCom under Authorization.

We still keep getting email alerts from loads of our clients. It looks like the exceptions we put in don't work. Any ideas?

 

regards,

Louis

    Hi  

    I am also interested to know whether exclusions are not working on a few of the devices or it's not working on any of the devices. Please make sure that all the devices have been updated with the latest policy push from enterprise console.

    Hi  

    Please suggest on my previous question whether you are receiving alerts for a few systems or all the systems.

    Hello Louis-M,

    first of all, you shouldn't use exclusions unless the integrity of the files is sufficiently safeguarded by some other means or the exclusion is absolutely necessary. Authorization is the proper way.

    I haven't seen that exclusions or authorizations aren't honoured (BTW: on-access and on-demand/scheduled scans have independent exclusions). The affected endpoints do comply with the AV&HIPS policy?

    The exclusions were put in as an attempt to stop the alerts. I didn't think we needed them at the time but put them in to see if they made any difference. I've now taken them out.

    So all that we have is the authorisation enabled as shown.

    The pc's affected (and there are more) do comply with the policy set.
