Meeting Database Audit Compliance Requirements

To meet compliance requirements, DBSS allows you to configure the retention period for audit logs, audit reports, and privacy audit logs

Configuring Audit Log Retention Duration

According to relevant audit laws and regulations, audit logs must be retained for at least half a year. DBSS automatically predicts whether the remaining storage space of the audit instance meets the compliance requirements. If the remaining storage space is insufficient, a message is displayed.

Figure 1 Insufficient disk space notice

If the message shown in Figure 1 is displayed, enable automatic backup. For details, see Automatically Backing Up Database Audit Logs.

If automatic backup is enabled, set Backup Period to Hourly.

If the total size of backup files generated every day is less than 50 MB, you are advised to select Daily.

Configuring Audit Reports

To check whether compliance requirements are met in a timely and accurate manner, you are advised to enable audit report for schedule tasks.

You are advised to configure reports as shown in Figure 2.

Configuring Privacy Data Protection

The SQL request statements and result sets in audit logs may contain users' privacy data. Therefore, you are advised to enable privacy data protection for audit logs.

Configure the following functions to meet privacy data compliance requirements:

  • Toggle on Mask Privacy Data. Privacy data in audit logs is masked for storage.
  • Toggle off Store Result Set. Result sets that contain privacy information will not be stored in audit logs.
  • Enable all privacy protection rules.
