   • Scanning an image
     1. In the Operation column of an image, click Scan.
     2. Confirm the image information and click OK to start the scan.
   • Manually scanning images
     1. In the upper right corner of the page, click Scan.

        Table 2 Manual scan parameters

        Parameter	Description	Example Value
        Risk Type	Select the types of risks to be scanned. HSS scans for software information, file information, and base images by default.	Select all
        Speed Limit for Third-party Image Repositories	If you have a large number of third-party images to be scanned, but you are worried that too much network bandwidth will be occupied if they are all scanned at once, you can click to set the number of images to be scanned per hour.	Unlimited
        Scan Tasks	A scan task occupies one pod. You can set the number of scan tasks running in the cluster. For example, if the number of scan tasks is set to 2, only two scan tasks can run in the cluster.	2
        Image Scope	Select All or specify images. A full scan takes a long time and cannot be stopped after it starts. Exercise caution when performing this operation.	All

     3. Click OK.
   • Scheduling image scans
     1. In the upper right corner of the page, click Scheduled Scan Policy.
     2. Set the scheduled scan parameters. For details, see Table 3.

        Table 3 Parameters of a scheduled scan policy

        Parameter	Description	Example Value
        Scheduled Scan Policy	Whether to enable scheduled scan. After this function is enabled, you can view and configure scheduled scan parameters. : disabled : enabled
        Scheduled Scan Period	Click to select the scan period. The scan time range is fixed to 00:00:00 - 07:00:00.	Every 3 days

        Speed Limit for Third-party Image Repositories	If you have a large number of images to be scanned, but you are worried that too much network bandwidth will be occupied if they are all scanned at once, you can click to set the number of images to be scanned per hour.	Unlimited
        Image Update Time Range	Select a range of image update time. It determines which images will be scanned. For example, if you set the scan time range to Last 15 days, HSS scans only the images updated in the last 15 days.	Last 15 days
        Scan Tasks	A scan task occupies one pod. You can set the number of scan tasks running in the cluster. For example, if the number of scan tasks is set to 2, only two scan tasks can run in the cluster.	2
        Image Repositories	Select the type of the images to be scanned.	Swr-private
