I don't only want to find 10.20.30.1 I want to find 10.20.30.x anything in that /24. than The use of data filtering security profiles in security rules can help provide protections of data exfiltration and data loss. There are two ways to make use of URL categorization on the firewall: By grouping websites into categories, it makes it easy to define actions based on certain types of websites. This action column is also sortable, which you can click on the word "Action".You will see how the categories change their order and you will now see "allow" in the Action column. After determining the categories that your company approves of, those categories should then be set to allow, which will not generate logs. Network beaconing is generally described as network traffic originating from victim`s network towards adversary controlled infrastructure that occurs at regular intervals which could be an indication of malware infection or compromised host doing data exfiltration.
