Vulnerability Scan

HSS can scan for Linux, Windows, Web-CMS, application, and emergency vulnerabilities. Automatic, scheduled, and manual scans are supported.

• Automatic scan

  By default, Linux, Windows, and Web-CMS vulnerabilities are automatically scanned every day. Application vulnerabilities are automatically scanned every Monday. The time of an automatic application vulnerability scan changes with the middleware asset scan time. For details about how to view and set the latter, see Asset Discovery.

  If a manual or scheduled vulnerability scan has been performed in a day, HSS will not automatically scan for vulnerabilities on that day.

• Scheduled scan

  By default, a full server vulnerability scan is performed once a week. To protect workloads, you are advised to set a proper scan period and scan server scope to periodically scan server vulnerabilities.

• Manual scan

  If you want to view the vulnerability fixing status or real-time vulnerabilities of a server, you are advised to manually scan for vulnerabilities.

This section describes how to manually scan for vulnerabilities and configure a scheduled scan policy.

Constraints

• If the agent version of the Windows OS is 4.0.18 or later, application vulnerability scan is supported.
• The Server Status is Running, Agent Status is Online, and Protection Status is Protected. Otherwise, vulnerability scan cannot be performed.
• For details about the types of vulnerabilities that can be scanned by different HSS editions, see Types of Vulnerabilities That Can Be Scanned and Fixed.
• For details about the OSs supported, see Table 1.

2. In the navigation pane, choose Prediction > Vulnerabilities.
3. Click Scan in the upper right corner of the Vulnerabilities page.

   To scan for emergency vulnerabilities, locate the row of an emergency vulnerability, and click Scan in the Operation column.

4. In the Scan for Vulnerability dialog box displayed, set the vulnerability types and scope to be scanned. For more information, see Table 2.

   Table 2 Parameters for manual scan vulnerabilities

   Parameter	Description	Example Value
   Type	Select one or more types of vulnerabilities to be scanned. Possible values are as follows: Linux Windows Web-CMS Application Emergency	Select all
   Scan	Select the servers to be scanned. Possible values are as follows: All servers Selected servers You can select a server group or search for the target server by server name, ID, EIP, or private IP address. NOTE: The following servers cannot be selected for vulnerability scan: Servers that are not in the Running state Servers whose agent status is Offline	All servers

5. Click OK.
6. Click Manage Task in the upper right corner of the Vulnerabilities page. On the Manage Task slide-out panel displayed, click the Scan Tasks tab to view the status and scan result of the vulnerability scan task.
