fAST Dynamic checkers

The fAST Dynamic scan engine uses multiple checkers to detect vulnerabilities in the target web application or API.

Checkers are either active or passive:

• Active checkers directly interact with the target website or API. They will craft and send attack payloads and then observe the target web application or API's behavior in order to identify security concerns.
• To enable active checkers in scans, you must select the Perform Active Attacks checkbox when creating the DAST project. See Create DAST projects for web applications and APIs.
• Passive checkers do not directly interact with the target web application or API. They observe requests and responses sent to and from the fAST Dynamic scan engine.

Checkers in DAST scans

This table lists all checkers used in DAST scans by fAST Dynamic.

Each checker is assigned a unique code. To enable or disable checkers from DAST scans, add or remove checker codes from your scan-settings.json configuration file. See Configure JSON scan settings and authentication profiles for more information. You can also modify the Checkers settings on the Scan settings subtab—see DAST scan settings for more information.
