This is achieved by populating IP Type as Private and Public based on PrivateIP regex. At the top of the query, we have several global arguments declared which can be tweaked for alerting. In order to use these functions, the data should be in correct order achieved from Step-3. Hi @RogerMccarrick You can filter source address as 10.20.30.0/24 and you should see expected result. Because we have retained the threat-prone sites, you will see that the action for some sites is set to "block". An alternate means to verify that User-ID is properly configured, view the URL Filtering and Traffic logs is to view the logs. ALLOWED/DENIED TRAFFIC FILTER EXAMPLES, ALL TRAFFIC THAT HAS BEEN ALLOWED BY THE FIREWALL RULES, Explanation: this will show all traffic that has been allowed by the firewall rules. WebConfigured filters and groups can be selected. We're sorry we let you down. Images used are from PAN-OS 8.1.13. In addition, the custom AMS Managed Firewall CloudWatch dashboard will also The same is true for all limits in each AZ. We can add more than one filter to the command. Do not select the check box while using the shift key because this will not work properly. CloudWatch logs can also be forwarded I created a Splunk dashboard that trends the denies per day in one pane and shows the allows in another pane. Add Security Profile to Security Policy by adding to Rule group used in security policy or directly to a security policy: Navigate to Monitor Tab, and find Data Filtering Logs. The timestamp of the next event is accessed using next function and later datetime_diff() is used to calculate time difference between two timestamps. So, with two AZs, each PA instance handles viewed by gaining console access to the Networking account and navigating to the CloudWatch CloudWatch Logs Integration: CloudWatch logs integration utilizes SysLog The logic or technique of the use-case was originally discussed at threat hunting project here and also blogged with the open source network analytics tool (flare) implementation by huntoperator here.
