Multiple malicious scans from the same source address - can I block IP automatically

[LucaMarchiori]

Occasionally, I notice that the firewall has been blocking tens or even hundreds of attempts from a single source address for multiple threats.  In a case like this, it seems obvious, for someone looking at the logs, that that source IP should have been temporarily blocked and possibly banned, but that does not happen automatically.  

We do have some exception in our vulnerability profile that change the action from reset to block-IP, for instance, but this only applies to a specific TID.  When you have a host combining say 5 or 10 different exploits in one minute, is there a way to configure the firewall to automatically block the offending IP?

Thanks,

Hi @ash83 

You need to start with a log forwarding profile, there you define a specific filter for the threatlogs (you either filter on the severity or on specific threat ID or something completely different). As action you then choose to tag the source or destination IP (depending on your filter) and assign a Tag to these IPs. After that you create a dynamic address group with the criteria the tag you created for that. From this point you can use the address group in your policy to block connections from or to these IPs.

Hope this helps.
