CockroachDB Audit Log

In today’s complex data landscape, maintaining comprehensive audit logs, especially through systems like the CockroachDB Audit Log, has become essential for organizations managing sensitive information. According to IBM’s Cost of a Data Breach Report 2024, organizations with properly implemented audit logs identify breaches 74 days faster, thus reducing costs by up to 28%. Undoubtedly, robust audit trails enhance security posture while simultaneously improving compliance readiness.

Though a powerful distributed SQL platform, CockroachDB provides native audit features that nevertheless offer the foundation needed to track database activities and identify suspicious behavior. Furthermore, these features help meet regulatory requirements without complex configuration. Unlike other solutions, this platform achieves this with minimal setup.

Our article explores native audit capabilities in CockroachDB and examines how third-party solutions enhance monitoring and security. Indeed, combining these approaches often yields the most comprehensive protection. Let’s examine the built-in features first.

Native CockroachDB Audit Log Capabilities

Various built-in mechanisms are available to establish audit logging through SQL interface and system tables. Although not as comprehensive as dedicated audit solutions, these native features still provide essential functionality for basic monitoring. Many organizations initially start with these features before eventually exploring advanced options. Understanding the core capabilities remains critical regardless of your implementation approach.

1. System Tables for Audit Logging

Internal system tables within the database capture valuable audit information. Administrators can query these tables to retrieve historical data. Automatic tracking of events occurs without requiring explicit configuration, which is certainly a time-saving benefit. Built-in functionality represents one of the platform’s key advantages:

-- Query recent login attempts
SELECT 
  event_timestamp,
  username,
  application_name,
  client_address,
  session_id
FROM 
  system.eventlog
WHERE 
  event_type = 'session_log' 
  AND "eventType" = 'CLIENT_SESSION_CONNECT'
ORDER BY 
  event_timestamp DESC
LIMIT 5;

Example output:

2. Creating Custom Audit Tables

Greater granular control comes from creating custom audit tables populated using triggers. Such an approach provides more flexibility than system tables alone. Custom tables allow storing context crucial for forensic analysis, thereby enhancing investigation capabilities. Additional benefits include tailored retention policies based on data sensitivity:

-- Create audit log table
CREATE TABLE audit_log (
    id UUID DEFAULT gen_random_uuid() PRIMARY KEY,
    timestamp TIMESTAMPTZ DEFAULT current_timestamp(),
    user_id STRING,
    action STRING,
    table_name STRING,
    query TEXT,
    old_value JSONB,
    new_value JSONB
);

-- Create indexes for performance
CREATE INDEX idx_audit_log_timestamp ON audit_log(timestamp);
CREATE INDEX idx_audit_log_user ON audit_log(user_id);
CREATE INDEX idx_audit_log_table ON audit_log(table_name);

After this structure is in place, you can set up triggers to populate the audit log. These triggers execute whenever data changes occur. Any modification automatically generates a corresponding audit entry. Overall, this approach provides comprehensive monitoring without requiring application changes:

-- Example trigger function for audit logging
CREATE OR REPLACE FUNCTION log_data_changes()
RETURNS TRIGGER AS $$
BEGIN
    IF (TG_OP = 'INSERT') THEN
        INSERT INTO audit_log (user_id, action, table_name, query, new_value)
        VALUES (current_user, 'INSERT', TG_TABLE_NAME, current_query(), to_jsonb(NEW));
    ELSIF (TG_OP = 'UPDATE') THEN
        INSERT INTO audit_log (user_id, action, table_name, query, old_value, new_value)
        VALUES (current_user, 'UPDATE', TG_TABLE_NAME, current_query(), to_jsonb(OLD), to_jsonb(NEW));
    ELSIF (TG_OP = 'DELETE') THEN
        INSERT INTO audit_log (user_id, action, table_name, query, old_value)
        VALUES (current_user, 'DELETE', TG_TABLE_NAME, current_query(), to_jsonb(OLD));
    END IF;
    RETURN NULL;
END;
$$ LANGUAGE plpgsql;

3. SQL Audit Views for Analysis

Creating views simplifies audit log analysis for security use cases. Views enable filtering of complex audit data and focus on high-risk activities. Sharing with security teams becomes possible without granting access to underlying tables. Security layers form naturally through views themselves. Most implementations align this approach with least-privilege security principles:

-- View for suspicious activities
CREATE VIEW suspicious_audit_events AS
SELECT
    timestamp,
    user_id,
    action,
    table_name,
    SUBSTRING(query, 1, 50) AS query_preview
FROM
    audit_log
WHERE
    (action = 'DELETE' AND table_name IN ('users', 'roles', 'permissions'))
    OR (action = 'UPDATE' AND table_name = 'user_roles')
    OR (user_id NOT IN (SELECT username FROM authorized_users) AND table_name IN ('sensitive_data', 'financial_records'));

4. Using CockroachDB CLI for Audit Log Management

Command-line interface allows querying and managing audit logs with powerful automation capabilities. Despite its text-based nature, CLI excels at scheduled tasks. Tools can be incorporated into scripts for regular reporting. Seamless integration with existing operational workflows becomes possible through this approach:

# Extract recent audit events to a CSV file
cockroach sql --execute="
COPY (
    SELECT timestamp, user_id, action, table_name, query
    FROM audit_log
    WHERE timestamp > current_timestamp - INTERVAL '24 hours'
    ORDER BY timestamp DESC
) TO '/tmp/recent_audit.csv' WITH CSV HEADER;"

Accessing Audit Logs via CockroachDB Web UI

Web-based administration interface with comprehensive monitoring capabilities comes built into the platform. Users can access visual tools for audit analysis effortlessly due to intuitive design. Many audit tasks are simplified through the web UI, offering the most user-friendly approach to monitoring. Advanced analysis might require exporting data for specialized tools:

1. Access the Web UI: Navigate to the CockroachDB Admin UI (typically at http://localhost:8080)
2. SQL Activity Dashboard: Review query execution and session information
3. Statement Statistics: Analyze query patterns and identify anomalies
4. Jobs Page: Monitor background processes and operations
