Fortinet FortiSIEM integration with Security Validation

This integration provides the following benefits:

• Validates that security tools are writing log events to Fortinet FortiSIEM to ensure compliance with security policies and regulations
• Collects events generated by Fortinet FortiSIEM to test the efficacy and configuration of security controls using Security Validation jobs

To configure an integration, this document walks you through the following high-level steps:

1. Configure the third-party technology
2. Configure Security Validation
3. Verify connectivity

API Calls

Supported Versions

• Fortinet FortiSIEM 7.5.0+

Before You Begin

To configure this integration, you need:

• The protocol used to connect to your Fortinet FortiSIEM instance (HTTPS is recommended)
• The hostname or IP address of the Fortinet FortiSIEM Supervisor
• The port of your Fortinet FortiSIEM instance (default is 443)
• A valid username and password for a user account with permissions to use the API endpoints described in the API calls table

Accounts and Permissions

To query the API, the user account associated with the credentials requires specific permissions. Ensure that the role assigned to the user account has read access to Incident and Event logs.

Configure Security Validation

1. Go to Settings > Integrations.

2. From the Integrations table, click Add Integration > Fortinet FortiSIEM.
   You can add this as either a Direct or Remote Integration.
3. Enter a meaningful Integration Name.
4. Optional: From the Proxy drop-down, choose a proxy profile if one is available. If one isn't available and all outbound connections go through a proxy, first, set up a Proxy Rule.
5. Optional: Change the HttpProtocols value to determine what protocol is used for requests (Https or Http). The default is Https.
6. Enter the Host value (hostname or IP address) for the Fortinet FortiSIEM Supervisor.
7. Enter a Port value. The default is 443.
8. Enter the Username for authentication. Use the format ORGANIZATION/USERNAME (for example, Super/apiAdmin or Super/my.user@mandiant.local), where Super is the default organization.
9. Enter the Password for authentication.
10. Optional: Check Verify Ssl if you want this verification done for requests to an upstream server.
11. Optional: Change the Timeout value if you want a different frequency of requests to an upstream server. The default is 30 (seconds).
12. Optional: Add or remove Queries, as needed. Defaults are provided for IP Query and Hostname Query.
13. Optional: Modify the FieldMapModel values, as necessary.
    • Each field map box can hold a JSON-formatted comma-separated list of columns returned by the API to be considered for each field when translating into the normalized event object format. Example: description could be configured to be 'msg_s' or 'SyslogMessage' in some environments. The field map tries both if set to: ['msg_s','SyslogMessage'] and whichever matches first is the column that is used.
    • When configuring an integration in Security Validation, you can assign additional host values in the Field Map settings. If none of the assigned fields return a valid host name, Network Actions may miss matched events from the third-party technology. Additional hosts values helps ensure the likelihood of a match between the two environments.
14. Optional: Change the value for Page Size (default 500) if needed.

15. Optional: Expand Advanced options and update the information as necessary.

    1. Update Query Time and Delay Time.
       The Query time is the amount of time (minutes) before and after the query runs that the platform looks for events, while the Delay time is the amount of time (minutes) that the platform waits to run the first query after a Job Action starts. For example, you configure your integration with the following values: Query time = 5, Query interval = 30 seconds, and Delay time = 0. When a Job Actions starts at 12:00:00, the first time the query runs, the platform looks for events from 11:55:00 to 12:00:00. Then 30 seconds later, it looks for events from 11:55:30 to 12:00:30. This interval continues, with the last query looking from 12:00:00 to 12:05:00. If you instead configured the Delay time to equal 10, it would run the same query, but it wouldn't start that query until 12:10:00.
       If your monitors are set to run more frequently than the query time, this configuration impacts the pass/fail results for AEDA monitors.
    2. Update Query Interval (seconds).
    3. If supported by your integration, configure correlation queries:
       1. Select Correlation Query Enabled and fill in the Correlation Query.
       2. Modify the Correlation Query Interval, if necessary (minutes).
    4. Select Discover network devices automatically, the default and recommended option.
       If unselected, reported events won't include product information for any matching network security technology.
    5. Select Save Suspicious Events.
    6. Modify the Event Time Adjustment (seconds). The default is 0.

    7. Modify the Limit value if you need to prevent a flood of results. This value is set to 10000 by default. This limit applies to both events and alerts individually, so if you set it to 10, you can still see a maximum of 10 events and 10 alerts.

16. Click Save.

Verify connectivity

1. Go to Settings > Integrations.
2. From the Direct Integrations table, click  > Test to verify that:
   • The Director can communicate with the integration host on the port and protocol specified.
   • The integration credentials are valid and working.

For more information on setting up queries, see Manage Integrations.
