Apache Cloudberry Audit Log

Apache Cloudberry audit logging capabilities provide organizations with essential tools for Database Activity Monitoring and securing their database operations. As detailed in the Cloudberry Security Guide, proper audit logging is fundamental to maintaining database security. According to the latest Cloud Security Alliance Report, 63% of organizations experienced cloud-based data breaches in 2024, with inadequate audit logging cited as a contributing factor in 45% of cases. This underscores the critical importance of implementing robust Audit Trails tracking mechanisms.

For organizations managing sensitive data in cloud environments, Cloudberry’s Audit Logs features offer comprehensive tracking and analysis capabilities that support both Data Security requirements and compliance mandates. This article explores how to implement and optimize Cloudberry’s audit logging functionality while ensuring optimal system performance.

Native Cloudberry Audit Log Features

Cloudberry includes built-in audit logging capabilities that track database operations, user activities, and system events. The audit logging system leverages Apache’s proven logging infrastructure while adding Database Security Goal enhancements for comprehensive monitoring.

Core Components

The Cloudberry audit logging system consists of several key components:

• Log Collectors: Distributed agents that capture Learning Rules and Audit data across database nodes
• Central Log Repository: Consolidated storage for audit logs with built-in redundancy
• Log Analyzers: Tools for processing and analyzing audit data
• Alert System: Real-time notification mechanism for Security Threats

Setting Up Basic Audit Logging

To enable audit logging in Cloudberry, you’ll need to configure the appropriate settings in the configuration file:

audit:
  enabled: true
  log_level: DETAILED
  storage:
    path: /var/log/cloudberry/audit
    retention_days: 90
  events:
    - type: DATABASE_ACCESS
    - type: DATA_MODIFICATION
    - type: SECURITY_EVENTS

After configuring these settings, you can verify the audit log status using the command line interface:

cloudberry audit-status

Example output:

Parameter	Value
Status	ACTIVE
Log Level	DETAILED
Storage Location	/var/log/cloudberry/audit
Current Log Size	156MB
Active Event Types	3
Last Log Entry	2025-02-21 09:15:22 UTC

Creating Custom Audit Rules

Cloudberry allows you to create custom audit rules to focus on specific activities:

CREATE AUDIT RULE sensitive_data_access AS
SELECT event_type, user_id, table_name, query_text
FROM audit_events
WHERE table_name IN ('customer_data', 'financial_records')
AND event_type = 'SELECT'
LOG LEVEL DETAILED;

Example audit rule output:

Event Type	User ID	Table Name	Query Text
SELECT	analyst_1	customer_data	SELECT * FROM customer_data WHERE region=’WEST’
SELECT	admin_user	financial_records	SELECT sum(amount) FROM financial_records
SELECT	service_acc	customer_data	SELECT email FROM customer_data

Advanced Audit Log Management

Log Rotation and Retention

Cloudberry implements automatic Audit Storage to manage storage efficiently:

# Configure log rotation
cloudberry-cli audit-config --rotate-size 500MB --rotate-time 24h

# Set retention policy
cloudberry-cli audit-config --retention-days 90 --compress-logs true

Log Rotation Configuration:

Parameter	Value
Size Threshold	500MB
Time Threshold	24 hours
Compression	Enabled
Current Log Files	12
Total Size	4.2GB
Oldest Log	2025-01-22

Analyzing Audit Logs

Cloudberry provides built-in tools for analyzing audit logs:

SELECT 
    DATE_TRUNC('hour', event_timestamp) as time_period,
    event_type,
    COUNT(*) as event_count,
    COUNT(DISTINCT user_id) as unique_users
FROM audit_log
WHERE event_timestamp >= CURRENT_DATE - INTERVAL '7 days'
GROUP BY 1, 2
ORDER BY 1 DESC;

Example analysis results:

Time Period	Event Type	Event Count	Unique Users
2025-02-21 09:00	SELECT	1,245	32
2025-02-21 09:00	UPDATE	156	8
2025-02-21 09:00	DELETE	12	3
2025-02-21 08:00	SELECT	987	28
