Malicious IP address log sudden increasein traffic

L0 Member

Our Malicious IP Traffic Alert typically registers a few dozen hits a day. However over the last weekend this has suddenly increased to a couple of thousand a day. I cannot see anything different apart from the quantity. The IP addresses are the same or from the same subnet.  Should I just leave it or what actions would you suggest.

Are you seeing these hits in a security policy. Probably using the PAN "malicious IPs"  dynamic address group?  Have you tried configuring a "Zone Protection Profile".  The default action is alert but you can configure it to drop or even drop for X minutes. If you are being scanned there is not much you can do other than drop the packets. If this was my network I would look at threat logs and try to determine what resource they are attacking. You probably have something exposed that has a vulnerability.

Yes they are set up to be dropped and that is working. It has always worked, its just that there has been a sudden and dramatic increase in these types of alerts so I am wondering if there is something else I should be alert to , as you mentioned, something exposed that has piqued some external interest.
