Palo Alto Firewall 9 Cloud Security Monitoring and Analytics
The Palo Alto Firewall app helps you to analyze traffic and gain a better understanding of your Palo Alto Networks environments. Dig deep into the data, broken down by threat detection indicators, malware type, and so in order to break out data for higher granularity.
The app uses Traffic and Threat logs.

Collecting Logs for Palo Alto Firewall 9
This section provides instructions for configuring log collection for the Sumo Logic App for Palo Alto Firewall 9, as well as sample log messages and a query example from an app dashboard. This includes the following tasks:
- Create a hosted collector with a Cloud Syslog source
- Define the destination for the logs.
- Configure syslog forwarding.
- Verify logs in Palo Alto Networks.
Step 1. Create a hosted collector and Cloud Syslog source
In this step, you configure a hosted collector with a Cloud Syslog source that will act as Syslog server to receive logs and events from Palo Alto Networks devices.
To configure a hosted collector with a Cloud Syslog source, do the following:
- Log in to Sumo Logic and create a Hosted Collector.
- Create a Cloud Syslog Source on the hosted collector, specifying the following:
- Enter a Source Name.
- Provide a Source Category: NW/PAN/V9
- Click Save.
- Copy the Token, host URL, and TCP TLS Port to a safe place. You will need this information in the tasks that follow.
Step 2. Define the destination for the logs
In this step, you create a server profile where you can define the log destination. This will be the hostname, port, and protocol (TLS) of the Sumo Logic Cloud Syslog source.
To create a server profile specifying the log destination, do the following:
- Login to the Palo Alto Networks Web interface as an administrative user.
- Select Device tab > Server Profiles > Syslog.
- Click Add at the bottom of the screen and provide endpoint details and a profile name, such as
- In the Syslog Server Profile window, select the Servers tab and click Add.
- In the Servers window, specify the following information:
- In the Syslog Server Profile window, select the Custom Log Format tab, and use the following custom format for the following log type:
$rule_uuid,$http2_connection #<Add your token from Step 1>
$rule_uuid,$http2_connection #<Add your token from Step 1>
- Click OK.
- Commit the changes.
Step 3. Configure syslog forwarding
To configure syslog forwarding for Traffic logs, follow the steps to Configure Log Forwarding as described in the Palo Networks documentation.
Step 4. Verify logs in Palo Alto Networks
In this step, you view logs using the Palo Alto Network Web interface to confirm the logs are generated on the firewall.
To verify the logs in Palo Alto Networks, do the following:
- In the Palo Alto Networks UI, select Monitor > Logs.
- Once the setup is done, log in to Sumo Logic.
- To validate that the logs are flowing to Sumo Logic, run a query using the source category you configured during Step 1, such as:
_sourceCategory = NW/PAN/V9.
Installing the PAN Firewall 9 Security App
Now that you have set up collection for the Palo Alto Networks Firewall 9 app, you can install the app and use the preconfigured searches and dashboards that provide insight into your data.
This app supports PAN-OS v8 and v9.
To install the app:
Locate and install the app you need from the App Catalog. If you want to see a preview of the dashboards included with the app before installing, click Preview Dashboards.
- From the App Catalog, search for and select the app.
- Select the version of the service you're using and click Add to Library. Version selection is applicable only to a few apps currently. For more information, see the Install the Apps from the Library.
- To install the app, complete the following fields.
- App Name. You can retain the existing name, or enter a name of your choice for the app.
- Data Source. Select either of these options for the data source.
- Choose Source Category, and select a source category from the list.
- Choose Enter a Custom Data Filter, and enter a custom source category beginning with an underscore. Example: (
- Advanced. Select the Location in Library (the default is the Personal folder in the library), or click New Folder to add a new folder.
- Click Add to Library.
Once an app is installed, it will appear in your Personal folder, or other folder that you specified. From here, you can share it with your organization.
Panels will start to fill automatically. It's important to note that each panel slowly fills with data matching the time range query and received since the panel was created. Results won't immediately be available, but with a bit of time, you'll see full graphs and maps.
Viewing Palo Alto 9 Security Dashboards
Security Analytics - Communication via Critical Ports
Palo Alto 9 - Security Analytics - Communication via Critical Ports dashboard provides analytics including trending for outbound communications via well known ports. Also provides additional analysis of application communications attempts across the firewall.
Use case: You can use this dashboard to analyze daily traffic patterns in outbound volumes of traffic for the following ports: 21, 22, 23, 53, 123, 137, 138, 389, 445, and 3389. The graph on the left compares the current day’s traffic volumes with the volumes of the same time one, two, and three days ago. The table on the right provides a sortable list of those connections.
Additionally at the top of the dashboard are two table containing analytics on known and unknown applications connections using the ports listed above.
Security Analytics - Outbound Traffic and Potential Exfiltration Activity
Palo Alto 9 - Security Analytics - Outbound Traffic and Potential Exfiltration Activity dashboard provides outbound traffic analysis including DNS activity for potential indicators of exfiltration activity.
Use case: You can use this dashboard to review volumes of outbound traffic by host, by application, and timeframe comparisons with last week. Increased and unaccounted for increases in traffic may be the result of unauthorized exfiltration of information. Additional analysis is provided for DNS traffic alone as large amounts of DNS traffic are not part of normal operations.
Security Analytics - Potentially Malicious Activity
Palo Alto 9 - Security Analytics - Potentially Malicious Activity dashboard provides information about traffic to and from IP addresses called out as potentially malicious by threat intelligence, countries that are on the OFAC (embargoed) list, and potential port scans.
Use case: You can use this dashboard to analyze attempted and successful connections to IP addresses on threat intelligence lists both inboudn and outbound. Additionally you can view connections to geolocation IP addresses associated with countries on the OFAC list (USA embargo list). Finally the bottom panel provides analysis on vertical port scans (one target, scanned on multiple network ports) and horizontal port scans (same port scanned across multiple destinations.)
Security Monitoring - THREAT Log by Category
Palo Alto 9 - Security Monitoring - THREAT Log by Category dashboard provides analytics about the THREAT type logs provided by the firewall. These are the indications of security events detected by the firewall’s defensive measures such as anti-malware, network intrusion detection, and the like.
Use case: You can use this dashboard to review THREAT events in summary or broken down by category: Command-and-control, Phishing, Malware, Proxy Anonymizers, Newly Registered Domains, Cryptocurrency, Questionable, and High-Risk.
Security Monitoring - THREAT Logs by Severity
Palo Alto 9 - Security Monitoring - THREAT Logs by Severity dashboard provides analytics about the THREAT type logs provided by the firewall. These are the indications of security events detected by the firewall’s defensive measures such as anti-malware, network intrusion detection, and the like.
Use case: You can use this dashboard to review THREAT events broken down by severity, allowing you to focus on the critical events first but also providing events of lesser severity for additional triage and investigation if necessary.
Security Monitoring - TRAFFIC Log Overview
Palo Alto 9 - Security Monitoring - TRAFFIC Log Overview dashboard provides monitoring of allowed and denied traffic over time by volume and host.
Use case: You can use this dashboard to monitor allowed and denied traffic through the firewall. Analysis is provided over time and in lists of top 10 sources, destinations, and hosts.
