Security Center:Use the CSPM feature

更新時間:Dec 13, 2024

The configuration errors of cloud services can cause risks such as vulnerabilities, performance bottlenecks, data leaks, and hacker attacks. The risks seriously affect the reliability of the cloud services. We recommend that you perform regular scans to check the configurations of cloud services and handle the risk items that are detected at the earliest opportunity. This helps improve the security, performance, and reliability of the cloud services and ensure service continuity and data security.

Prerequisites

  • Security Center is authorized to access your cloud resources. The Cloud Security Posture Management (CSPM) feature is purchased based on the pay-as-you-go billing method or a sufficient quota for the feature is purchased. For more information, see Authorization and purchase.

  • The cloud services that you want to check are added to Security Center. For more information, see Add cloud services.

Step 1: (Optional) Modify the configurations of a check item

Security Center allows you to modify the configurations of specific check items, such as Hotlink Protection Configurations, Ensure users not logged on for 90 days or longer are disabled for console logon, and Password Validity Check. You can modify the configurations of check items based on your business requirements to increase the accuracy of check results.

  1. Log on to the Security Center console. In the top navigation bar, select the region of the asset that you want to manage. You can select China or Outside China.

  2. In the left-side navigation pane, choose Risk Governance > Cloud Security Posture Management.

  3. Click the Configuration Check tab and click the name of a check item.

  4. In the details panel of the check item, click Parameter Configuration.

    Important

    In the details panel of a check item, if the Parameter Configuration button is displayed, the configurations of the check item can be modified. If the button is not displayed, the configurations of the check item cannot be modified.

  5. In the Parameter Configuration panel, select a parameter from the drop-down list in the Modifiable Parameter column, configure the parameter in the Edit Parameter column, and then click OK.

    You can click Add Modifiable Parameter to add and modify a parameter of the check item.

    The modification immediately takes effect. You can view the check result of the modified check item in the next configuration check.

Step 2: Run a configuration check

The CSPM feature supports full scans and scans by policy.

Full scan

If you want to immediately check whether risks exist in the configurations of your cloud services, perform the following operations to run a full scan:

  1. In the left-side navigation pane, choose Risk Governance > Cloud Security Posture Management.

  2. Click the Configuration Check tab, click Immediate Scan in the Actions section, and then select Full Scan.

Note

A full scan requires a period of time to complete.

Scan by policy

If you want to check whether risks exist in the configurations of specific cloud services, you must run periodic configuration checks or add specific check items for specific cloud service instances to the whitelist by creating the corresponding policies. To create the policies, perform the following operations:

  1. In the left-side navigation pane, choose Risk Governance > Cloud Security Posture Management.

  2. In the upper-right corner of the Cloud Security Posture Management page, click Check Policy Settings.

  3. In the Policy Management panel, configure a scan policy and a whitelist policy.

    • Scan Policy

      Configure items such as the check items used by a configuration check and the check cycle.

      1. On the Scan Policy tab, turn on Automatically Enable Cloud Security Posture Management.

      2. Configure the Detection Cycle and Detection Time parameters, select the required check items, and then click OK.

        After you select check items, the quota that is estimated to be consumed by a scan policy is displayed above the check item list. The estimated quota is for reference only because data may be created or released during a scan.

    • Whitelist Policy

      Exclude specific check items that are not required for configuration checks by cloud service instance or check item. Before you run a scan policy, you can specify check items and cloud service instances to create a whitelist policy. The configurations of a whitelist policy immediately take effect after you create the policy.

      1. On the Whitelist Policy tab, click Create Whitelist Policy.

      2. In the panel that appears, configure the Cloud Service Provider, Cloud Service, Check Item, and Policy Effective Scope parameters and click OK.

        If you set the Policy Effective Scope parameter to All Instances, the whitelist policy takes effect by check item. In subsequent configuration checks on new cloud service instances by policy, the check item that you specify for the whitelist policy is not used and is not displayed in the risk item list.

        If you set the Policy Effective Scope parameter to Specific Instances, the whitelist policy takes effect by cloud service instance. In subsequent configuration checks on new cloud service instances by policy, the check item that you specify for the whitelist policy is used.

      Note

      Check items that are added to the whitelist are automatically displayed in the list on the Whitelist Policy tab. You can find a check item on the Whitelist Policy tab and click Edit in the Actions column to modify the Policy Effective Scope parameter or click Delete in the Actions column to delete a whitelist policy.

After you configure a policy for the CSPM feature, Security Center runs configuration checks based on the time range that you specify in the policy. You can also select Scan By Policy to immediately check your cloud services.

  1. On the Cloud Security Posture Management page, click the Configuration Check tab.

  2. In the Actions section, click Immediate Scan and select Scan By Policy.

    Security Center immediately scans the configurations of cloud services based on the policy that you configure.

Step 3: View check results

  1. On the Configuration Check tab, view the check results.

    • View the overall information

      The section in the upper part of the Cloud Security Posture Management page displays the overall information about check results. You can view the pass rates for check items of the CIEM, Risk, and Compliance Risk types. You can move the pointer over the lines above Pass Rate to view the numbers of high-risk, medium-risk, low-risk, and passed check items.

      Important

      High-risk items pose major threats to your assets. We recommend that you handle these risk items at the earliest opportunity.

    • View risk items

      • In the All Check Items section, click a check item type. In the list of risk items on the right, view the risk items of the selected check item type.

      • Use the filter widget above the list to search for the risk items that you want to view. You can filter risk items by conditions such as the levels, status, and names of the risk items.

      • Above the list of check items, choose Yes in Fixing Supported or Not to view the check items that can be quickly fixed in the Security Center console.

Step 4: Handle the detected configuration risks

  1. In the Impact section of the details panel of a risk item, you can perform the following operations in the Actions column to handle the detected risks based on your business requirements.

    Operation

    Description

    Fix the risk item

    You can fix the risks detected in the configurations of the cloud service based on the information in the Solution and Help sections.

    Important
    • Security Center provides the quick fix feature for more than 100 check items. You can manually configure the fixing parameters in the Security Center console to directly fix the detected risks for cloud service instances.

    • In the Impact section, if the Fix button is displayed in the Actions column of an instance in the Not Passed state, the check item supports the quick fix feature. If the Fix button is not displayed, the check item does not support the quick fix feature.

      You can refer to Step 3: View check results to filter the risk items that can be quickly fixed in the Security Center console.

    • Quickly fix the check item in the Security Center console

      Find the instance that you want to manage and click Fix in the Actions column. In the panel that appears, you can view the information about the at-risk instance, scan time, and fixing parameters. Click Handle Now. If the fixing parameters can be modified, you can click Check Item Parameters in the panel. In the Parameter Configuration panel, modify parameter values in the Edit Parameter column. Then, click OK.

      You can also select multiple instances and click Fix below the instance list to quickly fix multiple instances at a time.

      Note
      • If the current account is not authorized to modify the configurations of cloud services of another account, you cannot perform quick fix on the cloud services of that account. To resolve this issue, click Authorize in the dialog box that appears.

      • When you modify the configuration parameters of a cloud service, if you are not reminded that the modification cannot be rolled back, you can roll back the configurations of the cloud service.

      • After you modify the configuration parameters of an instance, if you are required to restart the instance, restart the instance as prompted.

    • Fix the check item in the console of the cloud service

      Click the ID of an at-risk instance, such as an instance ID, an account ID, or a policy name, to go to the console of the cloud service and fix the detected risks.

    Add the risk item to the whitelist

    Important

    After you add a risk item to the whitelist, the risks that are detected for the risk item are no longer reported in subsequent configuration checks. We recommend that you add risk items to the whitelist only after you confirm that the risk items do not pose threats.

    If you confirm that a risk item does not pose threats to specific instances, you can add the risk item to the whitelist for the instances. Risk items that are added to the whitelist are not counted in the total number of risk items. You can click Check Policy Settings to go to the Policy Management panel, and click the Whitelist Policy tab to view the details of the check items that are added to the whitelist.

    You can also remove risk items from the whitelist.

  2. Verify fixes.

    If you have modified the configurations of an instance based on the information in the details panel of a risk item that affects the instance, you can click Verify in the Actions column to check whether the new configurations contain security risks.

    You can also select multiple instances and click Verify below the list to check whether the new configurations of the selected instances contain security risks.

    If the new configurations of an instance do not contain risks, the instance is removed from the list in the Impact section. After the new configurations of all at-risk instances are verified, the state of the risk item changes to Passed.

  3. Optional. After you use the quick fix feature of Security Center to fix risk items, you can click sas.configcheck.fix.manage in the upper-right corner of the CSPM page to view the history of quick fix.

    You can view information such as the fixing task ID, check item, and status. You can click the image icon in the Actions column and select Details to view the check item description, solution, help documentation, and fixing timeline. You can also perform operations such as rolling back and verifying configurations in the sas.configcheck.fix.manage panel.

View risk reports

You can view a risk report on the Risk Overview tab of the CSPM page. The report visualizes the overall configuration risks of your cloud assets and allows you to identify and handle configuration errors at the earliest opportunity.

  1. In the left-side navigation pane, choose Risk Governance > Cloud Security Posture Management.

  2. On the Risk Overview tab, select the cloud service provider of the cloud assets that you want to view. If you do not select an option, you can view the risk data of all cloud assets.
