 # Configure System-Wide CVE Whitelists
 
 When you run vulnerability scans, images that are subject to Common Vulnerabilities and Exposures (CVE) are identified. According to the severity of the CVE and your security settings, these images might not be permitted to run. As a Harbor system administrator, you can create whitelists of CVEs to ignore during vulnerability scanning.

 To connect Harbor to additional vulnerability scanners, you must install and configure an instance of the additional scanner according to the scanner vendor's requirements. The scanner must expose an API endpoint to allow Harbor to trigger the scan process or get reports. You can deploy multiple different scanners, and multiple instances of the same type of scanner.

 # Vulnerability Scanning
 
 Harbor provides static analysis of vulnerabilities in images through the open source [Clair](https://github.com/coreos/clair) project. 
 
 **IMPORTANT**: Clair is an optional component. To be able to use Clair you must have enabled Clair when you installed your Harbor instance. 
 
-You can also connect Harbor to your own instance of Clair or to additional vulnerability scanners by using an interrogation service. You configure additional scanners in the Harbor interface, after you have installed Harbor. For the list of additional scanners that are currently supported, see the [Harbor Compatibility List](harbor_compatibility_list.md#scanner-adapters).

For the list of additional scanners that are currently supported, see the [Harbor Compatibility List](../../install_config/harbor_compatibility_list.md#scanner-adapters).
 
 It might be necessary to connect Harbor to other scanners for corporate compliance reasons, or because your organization already uses a particular scanner. Different scanners also use different vulnerability databases, capture different CVE sets, and apply different severity thresholds. By connecting Harbor to more than one vulnerability scanner, you broaden the scope of your protection against vulnerabilities.

+For information about installing Harbor with Clair, see the [Run the Installer Script](../../install_config/run_installer_script.md). 
 
 You can manually initiate scanning on a particular image, or on all images in Harbor. Additionally, you can also set a policy to automatically scan all of the images at specific intervals.
