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://126.96.36.199 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
