Out-of-the-Box Detection Rules

Scanner provides pre-configured detection rules for common enterprise log sources, enabling immediate security monitoring capabilities across your cloud and SaaS infrastructure. These detections are maintained as YAML files in public GitHub repositories, making them easy to review, import, and customize.

Adding Detection Rules to Scanner

To add these detection rules in your Scanner environment:

• Navigate to Detections.

• Click New > Add Rules From Github:

• Under Connected Repositories, click Add Repository:

• Under Repository, enter the name of the repository containing the out-of-the-box detection rules you want to add, eg. scanner-inc/detection-rules-aws-cloudtrail. A matching option should appear in the dropdown list - click it:

• Under Branch, select main.

• Once the repository and branch have been selected, you should see Assign Event Sinks, which will allow you to send alerts of different severity levels to different destinations as you wish:

• Click Add Repository.

The out-of-the-box detection rules will be continuously synced to your environment as new commits are pushed to the main branch of the repository.

Customization

Scanner's detection rules are designed to be flexible and adaptable to your organization's specific needs. You can fork any of the detection rule repositories to create your own customized version while maintaining the ability to pull updates from the official repositories. Through Scanner's interface, individual rules can be enabled or disabled, allowing you to activate only the detections relevant to your environment.

Detection rules include configurable parameters that can be adjusted to match your security requirements, such as detection thresholds, time windows, and severity levels. These parameters can be modified in the YAML files to optimize detection sensitivity for your environment.

If you develop improvements that could benefit the broader community, you can contribute them back to the main repositories through pull requests.
