How to block command & control traffic on IP address

L0 Member

Targeted Command & control processes or nefarious data extractions primarily go outbound using a IP address rather than a FQDN for the URI.

In PRISMA how can i create a rule to block all all outbound traffic directed at IP addresses (not preknown) , unless address is in an exception group ?

Aware that IP directed requests like https://1.2.3.4 can be detected as medium risk,  category unknown , but applying a rule to that, blocks all traffic, as its applied at the HIP profile. I can apply to specific sites but that defeats the purpose, which is to auto block C&C activity or data extractions as i don't know in advance where the attackers are going to direct traffic.

 

If PRISMA is only getting the IP address, then is it possible to have a rule enforced client side by the agent maybe
