How to track inbound and outbound traffic from firewall logs

[ashferns08]

Hi helpful people,

I am trying to create a use case which will monitor source and destination traffic(like both communicating with each other)

For eg, malicious src connecting with internal IP's and Internal Ip's responding back to the same destination.

The idea is monitor internal sources that communicating outside and outside responding back to same source and to record the bytes_out, bytes_out and port details.
