Feed with mixed IP \ domains

apackard — Thu, 21 Mar 2019 19:29:02 GMT

I have an IoC that is a mixture of IP addresses and hostname\domains; what is the best way of handling this?

The processed output will be a mixture of PA firewalls and other non-PA systems so, to be absolutely sure I'd like to split them out.

The best way I can think of is to create 2 miners and use regex filters to access the same feed twice, once to extract the IP's and the second time to extract the domains, but just wanted to make sure I'm not missing a trick with inherant aggregation\output capabilities.

Thanks

Im pretty confident that, at least for Palo Alto, you can import an EDL which contains both, but the firewall will only import the assigned type.

Example:

Output feed has the following indicators:

8.8.8.8

dns.google.com

EDL config in firewall, type set to IPv4. or domain respectively.
