Comprehensive Guide to TiDB Data Audit Trail

Introduction

For many businesses using relational databases like TiDB that handle sensitive customer data, implementing comprehensive audit trail systems has become a fundamental security requirement. As a result, organizations utilizing these audit capabilities can better meet modern security standards while ensuring compliance for their stored data.

Recent data from Check Point Research highlights the urgency – cyberattacks surged by 30% in Q2 2024 compared to the previous year, marking the highest increase in two years. This therefore underscores the critical importance of implementing robust database audit solutions for TiDB and other database systems.

Understanding TiDB Data Audit Trail

TiDB provides robust monitoring and auditing capabilities through its integrated monitoring framework. While the monitoring features are primarily designed for performance analysis and system health tracking rather than compliance auditing, understanding these capabilities is important for a complete security strategy.

Core Monitoring Interfaces

The monitoring infrastructure consists of two main components:

1. PD Dashboard
2. Accessible via http://{IP}:2379/dashboard
3. Provides real-time visualization of:
   • Cluster status and performance metrics
   • Storage usage statistics
   • Node status monitoring
   • Region distribution data

For detailed information about the PD Dashboard, see the Dashboard Introduction.

1. Grafana Integration
2. Commonly accessible via http://{IP}:3000/login
3. Features pre-configured monitoring dashboards
4. Offers visualization for:
   • Query execution metrics
   • Resource utilization data
   • Performance statistics
   • System health indicators

Learn more in the TiDB Monitoring Framework documentation.

Monitoring vs. Auditing

While TiDB's monitoring capabilities provide excellent operational visibility, it's important to note that these features are distinct from true audit logging. For compliance-focused auditing requirements, organizations should consider additional solutions or enterprise features that provide proper audit trail capabilities.

TiDB Data Audit Trail Configuration and Tracking

For proper audit trail management, TiDB provides dedicated auditing features. Here's a basic setup:

-- Enable audit logging
SET GLOBAL tidb_audit_enabled = ON;
SET GLOBAL tidb_audit_log_format = 'text';  -- or 'json'

-- Create and test an audit filter
SELECT audit_log_create_filter('all_dml', '{
    "filter": [
        {
            "class": ["QUERY_DML"],
            "status_code": [0,1]
        }
    ]
}');

-- Apply the filter to all users
SELECT audit_log_create_rule('%@%', 'all_dml');

After configuration, you can perform some test operations:

CREATE TABLE test_audit (id INT, data VARCHAR(255));
INSERT INTO test_audit VALUES (1, 'test data');
UPDATE test_audit SET data = 'modified data' WHERE id = 1;

The resulting audit log (in text format) would look like:

[2024/02/11 10:15:20.123 +00:00] [INFO] [ID=x-123] [EVENT="QUERY,QUERY_DML,INSERT"] 
[USER=root] [CONNECTION_ID=123] [TABLES="test.test_audit"] [STATUS_CODE=1] 
[SQL_TEXT="INSERT INTO test_audit VALUES (1, 'test data')"]

[2024/02/11 10:15:25.456 +00:00] [INFO] [ID=x-124] [EVENT="QUERY,QUERY_DML,UPDATE"] 
[USER=root] [CONNECTION_ID=123] [TABLES="test.test_audit"] [STATUS_CODE=1] 
[SQL_TEXT="UPDATE test_audit SET data = 'modified data' WHERE id = 1"]

This audit trail provides:

• Detailed user activity tracking
• SQL statement recording
• Timestamp and connection information
• Operation status and affected tables
• Structured format for compliance reporting

Unlike monitoring metrics which focus on performance and resource usage, these audit logs are designed specifically for compliance and security tracking purposes.

Note: TiDB database auditing is an Enterprise Edition feature, as mentioned in the documentation. It's not available in the standard Community Edition or in the playground.
