Procedure

The following procedure shows how to run a manual scan task to scan for server vulnerabilities.

Log on to the Security Center console.
In the left-side navigation pane, choose Precaution > Vulnerabilities.
On the Vulnerabilities page, click Scan now below Latest System Vul Time.
In the One-click detection dialog box, select the types of vulnerabilities or issues that you want to detect and click OK.
The quick scan feature can be used to check the following items:
- Vul: Linux software vulnerabilities, Windows system vulnerabilities, Web-CMS vulnerabilities, application vulnerabilities, and urgent vulnerabilities.
  
  Note For more information, see Check items supported by each edition.
- Baseline problems: The baseline check feature is a value-added service provided by Security Center. Only the users of the Advanced, Enterprise, and Ultimate editions can enable and use this feature. You can select an existing baseline check policy or create a policy to use the quick scan feature. Only users of Security Center Enterprise can create policies. Users of Security Center Advanced can select only the default policy to run baseline checks. For more information about how to create a baseline check policy, see Set baseline check policies.
- Configuration Assessment: Security Center checks whether the configurations of Alibaba Cloud services contain risks.
After you click Scan now, Security Center scans all protected assets. It may take 1 to 5 minutes to run the scan task. Wait for the task to complete.
After the scan is complete, you can view the latest scan results.
