About the security baseline check feature

In compliance with the Information Security Technology - Data Security Capability Maturity Model (GB/T 37988-2019), DSC supports the following security baselines: the China Personal Information Protection Law (PIPL) and the best practices of Alibaba Cloud for data security. The preceding security baselines are intended for complex database environments in the cloud and different types of structured and unstructured data. DSC provides seven types of check policies and check items, an overview and a list of configuration risks by type and level, and suggestions on how to handle the detected configuration risks. The actual check items that are displayed on the Baseline Check > Baseline Management page shall prevail. We recommend that you handle configuration risks at the earliest opportunity based on the suggestions. This helps enhance the security of your data assets and protect the assets against attacks.

Security baselines

• The China PIPL: provides full-lifecycle security monitoring for personal information and data assets based on the PIPL.

  You can perform baseline checks on the database instances and Object Storage Service (OSS) buckets that contain personal information or sensitive personal information scanned by data identification tasks.

• Best practices of Alibaba Cloud for data security: provide full-lifecycle security monitoring for data assets based on the best practices of Alibaba Cloud for data security.

  You can perform baseline checks on the database instances and OSS buckets that DSC is authorized to access.

Check policies

Supported data types

The security baseline check feature can scan for configuration risks only for Alibaba Cloud databases that are connected to DSC. The following Alibaba Cloud database services are supported by the security baseline check feature.

Enable or disable the check items in check policies

By default, all check items in the check policies are enabled in the DSC console. You can enable or disable check items based on your business requirements.

1. Log on to the DSC console.

2. In the left-side navigation pane, choose Baseline Check > Baseline Management.

3. On the Alibaba Cloud Data Security Best Practices or PIPL-based Security Baseline Check tab of the Baseline Management page, view the baseline check policies.

4. In the check policy list, select a check item and turn on or off the switch in the Status column to enable or disable the check item.

   You can also enable or disable a check policy to enable or disable all check items of the policy.

   

Perform checks

View the time when the last check was performed.

On the Baseline Management page, click the Alibaba Cloud Data Security Best Practices or PIPL-based Security Baseline Check tab to view the value of the Last Checked Time parameter.

Automatically perform checks

By default, DSC automatically performs a check on the databases connected to DSC at approximately 01:00:00 (UTC+8) every day.

Manually perform checks

When a new data asset is connected to DSC or the database configurations are modified, you can click Re-check in the DSC console to immediately perform a check. A re-check takes about 10 minutes.

1. In the left-side navigation pane, choose Baseline Check > Risk Trends.

2. Click the Alerts tab. Select a policy and click Details in the Actions column.

3. On the Risk Situation or Assets tab, click Re-check to perform a re-check based on check items or data assets.

   

View the trend of asset risks

DSC integrates security baseline checks and sensitive data detection results to provide charts that display the security risks in data assets of different sensitivity levels, the security risks in personal and private data, the risk scan progress, and sensitive data detection results. The information helps you learn about the trend of your asset risks.

1. In the left-side navigation pane, choose Baseline Check > Risk Trends.

2. Select a baseline type from the drop-down list on the right side of Risk Trends.

3. On the Asset Risks tab, you can view the following information:

   • Data Asset Sensitivity Situation

     A column chart that displays the numbers of detected high-risk assets, medium-risk assets, and low-risk assets.

   • Security Situation of Sensitive Data

     A column chart that displays the numbers of detected high-risk assets, medium-risk assets, and low-risk assets of sensitive personal information, personal information, and general information.

   • Risk governance progress

     • The number displayed in the Progress column indicates the number of passed check items and the total number of check items for each asset. For example, if 2/3 is displayed for an asset, it means that a total of 3 check items apply to the asset and the asset has passed 2 check items. If Completed is displayed in the Progress column, it means that the asset has passed all applied check items.

     • The Risk Level column displays the risk levels of failed check items. If multiple levels of risks are detected in a failed check item, only risks of the highest level are displayed.

Handle asset risks

DSC allows you to view and handle asset risks from different perspectives. You can view information about asset risks from different perspectives on different pages. The details of risks on different pages are consistent. You can choose a perspective based on your business requirements.

From the asset perspective

To view risks from the asset perspective, go to the DSC console, choose Security Posture > Baseline Check in the left-side navigation pane, and then click the Asset Risks tab. You can view the list of datasets that can be scanned by DSC. This tab also provides entries to the scan result and risk handling.

   • Handle risks

     DSC provides suggestions for risk handling. You need to manually handle the detected risks. Select a data asset and click Handle in the Actions column to view the failed check items and the suggestions for risk handling.

     In the Risk Details section, click Handle to handle the risk on the page that appears.

     

• Add an asset to the scan whitelist

  If security baseline checks are not required for a database according to the evaluation result of the security engineer, you can click Add to Whitelist in the Actions column to add all check items that apply to the database to the scan whitelist. After you add the asset to the whitelist, Completed is displayed in the Progress column.

• Add a specific check item that applies to a data asset to the whitelist

  If a specific check item is not required for a database according to the evaluation result of the security engineer, click Handle in the Actions column. In the Risk Governance panel, select the check item and click Add to Whitelist on the right side of the check item. After you add the check item to the whitelist, Added to Whitelist is displayed for the check item.
