Vulnerability Scan

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

  • Automatic scan

    When collecting asset fingerprints, HSS automatically scans vulnerabilities. For Linux, Windows, and Web-CMS vulnerabilities, HSS scans them based on the software collection period. For application vulnerabilities, HSS scans them based on the middleware collection period. For details about the asset fingerprint collection period, see Collecting Server Asset Fingerprints.

    If vulnerabilities have been manually scanned or a scheduled vulnerability scanning task has been triggered within the asset fingerprint collection period, HSS will automatically scan vulnerabilities when collecting asset fingerprints next time. This collection mode is affected by the other two scanning modes, and the scanning period is not fixed. You are advised to use the other two scan methods.

  • Scheduled scan

    By default, HSS performs a full server vulnerability scan once a week. To ensure service security, 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. If the agent version of the Linux OS is 3.2.9 or later, emergency vulnerability scan is supported. For details about how to upgrade the agent, see Upgrading the Agent.
  • 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 by Linux and Windows vulnerability scan, see Table 1. Emergency vulnerability scan supports Ubuntu, CentOS, EulerOS, Debian, and AlmaLinux.

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

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

  5. In the Scan for Vulnerability dialog box displayed, select the vulnerability type and scope to be scanned. For more information, see Table 2.

    Table 2 Parameters for manual scan vulnerabilities

    Parameter

    Description

    Type

    Select one or more types of vulnerabilities to be scanned. Possible values are as follows:

    • Linux
    • Windows
    • Web-CMS
