CockroachDB Audit Tools

In today’s data-driven landscape, organizations face increasing pressure to protect their database assets. According to the 2024 Ponemon Institute Database Security Report, 78% of surveyed organizations experienced at least one database breach in the past two years, with 42% attributing inadequate audit capabilities as a contributing factor.

For organizations using CockroachDB, implementing robust audit tools is critical for maintaining data security, achieving regulatory compliance, and ensuring data integrity. This article explores CockroachDB’s built-in audit functionalities and examines how third-party tools like DataSunrise can enhance your database security posture.

Native CockroachDB Audit Tools

CockroachDB provides several built-in mechanisms for auditing database activities. These native tools offer fundamental capabilities for tracking user actions, query execution, and system events.

1. System Tables and Event Logs

CockroachDB maintains internal system tables that capture valuable audit information. The system.eventlog table records significant events like cluster membership changes, schema alterations, and privilege modifications:

-- Query recent schema changes
SELECT 
  timestamp, 
  "reportingID", 
  info 
FROM system.eventlog 
WHERE event_type = 'schema_change' 
ORDER BY timestamp DESC 
LIMIT 5;

2. SQL Statistics Tables

CockroachDB maintains detailed statistics about query execution through its internal crdb_internal.statement_statistics view:

-- Examine recent SQL statement execution
SELECT 
  application_name,
  query_summary,
  execution_count,
  mean_service_latency,
  max_retries
FROM crdb_internal.statement_statistics 
ORDER BY last_execution_timestamp DESC
LIMIT 5;

3. Custom Audit Tables with Triggers

For more comprehensive auditing, database administrators can implement custom audit tables with triggers:

-- Create audit table
CREATE TABLE audit_events (
  id UUID DEFAULT gen_random_uuid() PRIMARY KEY,
  event_time TIMESTAMPTZ DEFAULT current_timestamp(),
  username STRING NOT NULL,
  action STRING NOT NULL,
  table_name STRING,
  query_text STRING,
  row_data JSONB
);

-- Create function for audit logging
CREATE FUNCTION log_table_changes() RETURNS TRIGGER AS $$
BEGIN
  INSERT INTO audit_events (username, action, table_name, query_text, row_data)
  VALUES (
    current_user,
    TG_OP,
    TG_TABLE_NAME,
    current_query(),
    CASE 
      WHEN TG_OP = 'DELETE' THEN to_jsonb(OLD)
      ELSE to_jsonb(NEW)
    END
  );
  RETURN NULL;
END;
$$ LANGUAGE plpgsql;

-- Apply trigger to sensitive table
CREATE TRIGGER audit_customer_data
AFTER INSERT OR UPDATE OR DELETE ON customer_data
FOR EACH ROW EXECUTE FUNCTION log_table_changes();

4. Using CockroachDB’s Command Line Interface for Auditing

The CockroachDB CLI offers capabilities for extracting and analyzing audit information:

# Export audit records to CSV for analysis
cockroach sql --execute="
COPY (
  SELECT 
    event_time, 
    username, 
    action, 
    table_name, 
    query_text 
  FROM audit_events 
  WHERE event_time > current_timestamp - INTERVAL '7 days'
) TO '/tmp/weekly_audit.csv' WITH CSV HEADER;"

5. CockroachDB Web UI for Monitoring

CockroachDB provides a web-based interface that includes monitoring capabilities for real-time observation of database activities:

1. Access the web UI (typically at http://localhost:8080)
2. Navigate to the “SQL Activity” dashboard
3. Review active sessions, recent queries, and transaction statistics
4. Examine the “Statements” tab for comprehensive query analysis

Limitations of Native Audit Tools

While CockroachDB’s native audit capabilities provide essential functionality, they have several limitations:

• Limited Granularity: Native tools may not capture all required details for comprehensive database activity monitoring
• Manual Configuration: Implementing custom audit solutions requires significant effort and maintenance
• Performance Impact: Extensive auditing can affect database performance without careful optimization
• Basic Alerting: Limited real-time notification capabilities for security events
• Compliance Gaps: May not fully satisfy complex regulatory requirements without additional tooling
