Configuring the Database Audit Logs

Prerequisites

Database audit logs are configured on the Security Settings page. You can change security settings only when the cluster status is Available and Unbalanced, and Task Information cannot be Creating snapshot, Scaling out, Configuring, or Restarting.

Procedure

1. Log in to the GaussDB(DWS) console.
2. Choose Cluster > Dedicated Cluster.
3. In the cluster list, click the name of a cluster. Choose Security.

   By default, Configuration Status is Synchronized, which indicates that the latest database results are displayed.

4. In the Audit Settings area, set the audit items:
   

   The default audit log retention policy is space-first, which means audit logs will be automatically deleted when the size of audit logs on a single node exceeds 1 GB. This function prevents node faults or low performance caused by high disk space occupied by audit logs.

   Figure 1 Audit items
   

   Table 1 describes the detailed information about the audit items.

   Table 1 Audit items

   Audit Item	Description
   Unauthorized access	Specifies whether to record unauthorized operations. This parameter is disabled by default.
   DQL operations	SELECT operations can be selected. NOTE: 8.1.1.100 and later versions support the DQL operations audit item.
   DML operations	Specifies whether to record INSERT, UPDATE, and DELETE operations on tables. This parameter is disabled by default. NOTE: The cluster supports fine-grained audit items in 8.1.1.100 or later. COPY and MERGE are added.
   DDL operations	Specifies whether to record the CREATE, DROP, and ALTER operations of specified database objects. DATABASE, SCHEMA, and USER are selected by default. NOTE: The cluster supports TABLE, DATA SOURCE, and NODE GROUP operations in 8.1.1.100 or later. These operations are enabled by default.
   Other operations	Specifies whether to record other operations. Only the TRANSACTION and CURSOR operations are selected by default. NOTE: 8.1.1.100 and later versions support the Other operations audit item. You are advised to select TRANSACTION. Otherwise, statements in a transaction will not be audited. You are advised to select CURSOR. Otherwise, SELECT statements in a cursor will not be audited. The Data Studio client automatically encapsulates SELECT statements using CURSOR.

   Except the audit items listed in Table 1, key audit items in Table 2 are enabled by default on GaussDB(DWS).

   Table 2 Key audit items

   Parameter	Description
   Key audit items	Records successful and failed logins and logout.
   	Records database startup, stop, recovery, and switchover.
   	Records user locking and unlocking.
   	Records the grants and reclaims of user permissions.
   	Records the audit function of the SET operation.

5. Enable or disable audit log dumps.
