Database Audit in CockroachDB

Implementing a robust database audit for CockroachDB has become essential for modern organizations managing sensitive data. Recent findings from Gartner’s 2024 Database Security Trends Report indicate that 65% of data breaches involve inadequate database auditing practices, highlighting the critical importance of comprehensive audit solutions for database systems like CockroachDB.

Understanding Database Audit in CockroachDB

Database activity monitoring in CockroachDB involves systematically tracking and recording database operations to maintain accountability and security. This includes monitoring user sessions, query execution, schema changes, and access patterns. While CockroachDB provides native auditing capabilities, organizations often need to implement additional measures to meet comprehensive security requirements.

Native Database Audit Features

1. System Tables and Views

CockroachDB maintains system tables that track various aspects of database activity history. Here’s an example of creating a login audit view:

CREATE VIEW login_audit AS
SELECT 
    event_timestamp,
    user_name,
    client_address,
    auth_scheme,
    status
FROM system.authentication_audit_events
WHERE event_type = 'LOGIN_ATTEMPT'
ORDER BY event_timestamp DESC;

Example output:

event_timestamp	user_name	client_address	auth_scheme	status
2024-02-18 10:15	admin	192.168.1.100	password	success
2024-02-18 10:14	john_doe	192.168.1.101	certificate	failed
2024-02-18 10:12	system	192.168.1.102	password	success

2. Custom Audit Tables

Implementing custom audit trails allows for more detailed tracking:

CREATE TABLE database_audit_log (
    audit_id UUID DEFAULT gen_random_uuid(),
    event_timestamp TIMESTAMP DEFAULT current_timestamp(),
    user_name STRING NOT NULL,
    operation_type STRING NOT NULL,
    object_name STRING,
    INDEX (event_timestamp DESC)
);

Sample audit log entries:

audit_id	event_timestamp	user_name	operation_type	object_name
a001	2024-02-18 10:20	admin	INSERT	users
a002	2024-02-18 10:19	admin	UPDATE	accounts
a003	2024-02-18 10:18	john_doe	SELECT	customers

3. Sensitive Data Monitoring

For tracking access to sensitive data, create specialized views:

CREATE VIEW sensitive_data_audit AS
SELECT 
    event_timestamp,
    user_name,
    operation_type,
    object_name,
    status
FROM database_audit_log
WHERE object_name IN ('customer_data', 'financial_records');

Example sensitive data audit results:

event_timestamp	user_name	operation_type	object_name	status
2024-02-18 11:15	admin	SELECT	customer_data	success
2024-02-18 11:14	analyst	UPDATE	financial_records	denied
2024-02-18 11:12	system	SELECT	customer_data	success

Using CockroachDB Web UI for Auditing

CockroachDB’s web interface provides built-in monitoring capabilities accessible through your browser:

1. Access the web UI (typically at http://localhost:8080)
2. Navigate to the “SQL Activity” dashboard to view:
   • Active queries and sessions
   • Query statistics
   • User activity patterns
   • Performance metrics
3. Use the “Transactions” page to analyze query patterns and identify potential security issues
4. Monitor authentication events through the “Security” section
