Database Audit for Cloudberry

Database audit for Cloudberry provides essential security controls in an environment of increasing data risks. The Identity Theft Resource Center reported 3,205 data breaches in 2023. These breaches affected 349 million people. This is a 78% increase from last year. Organizations can strengthen their security posture through effective database auditing practices. This article examines Cloudberry’s audit capabilities and practical implementation approaches for protecting organizational data.
Understanding Cloudberry Native Database Audit
Cloudberry provides powerful native database auditing capabilities that help organizations track and monitor database activities. These features leverage SQL language components, including views and stored procedures, to maintain detailed audit trails of database operations.
Core Audit Features
Cloudberry’s native audit functionality includes:
- Real-time monitoring of database operations
- Detailed activity logging with timestamp and user information
- Customizable audit rules and filters
- Integration with existing security frameworks
- Performance optimization for minimal impact on database operations
Setting Up Basic Database Auditing
To implement native database auditing in Cloudberry, follow these steps:
-- Create audit table CREATE TABLE audit_log ( audit_id SERIAL PRIMARY KEY, table_name VARCHAR(50), operation_type VARCHAR(20), modified_by VARCHAR(50), modification_time TIMESTAMP, old_value TEXT, new_value TEXT ); -- Create audit trigger function CREATE OR REPLACE FUNCTION audit_trigger_function() RETURNS TRIGGER AS $$ BEGIN IF TG_OP = 'INSERT' THEN INSERT INTO audit_log ( table_name, operation_type, modified_by, modification_time, new_value ) VALUES ( TG_TABLE_NAME, TG_OP, current_user, current_timestamp, row_to_json(NEW)::text ); END IF; RETURN NEW; END; $$ LANGUAGE plpgsql;
Using Cloudberry CLI for Audit Management
Cloudberry’s command-line interface provides essential tools for managing audit settings and viewing audit logs. Here are executed examples with their outputs:
Enable auditing for login events:
ALTER DATABASE CloudberryDB SET AUDIT_CONTROL = 'LOGIN_AUDIT'; -- Output: Database altered.
Query recent login audit events:
SELECT event_time, login_name, client_ip, action_name FROM sys.dm_audit_actions WHERE event_time > DATEADD(hour, -24, GETDATE()) ORDER BY event_time DESC;Example Output:
event_time | login_name | client_ip | action_name |
---|---|---|---|
2024-02-04 15:30:22 | admin_user | 192.168.1.100 | LOGIN |
2024-02-04 15:28:15 | app_service | 192.168.1.101 | FAILED_LOGIN |
2024-02-04 15:25:01 | audit_user | 192.168.1.102 | LOGOUT |
View audit specifications:
SELECT audit_id, name, status_desc, audit_file_path FROM sys.server_audits;Example Output:
audit_id | name | status_desc | audit_file_path |
---|---|---|---|
1 | SecurityAudit | ACTIVE | /var/log/audit/ |
2 | AccessAudit | ACTIVE | /var/log/audit/ |
Check failed login attempts in the last hour:
SELECT event_time, server_principal_name, client_ip, error_number FROM sys.fn_get_audit_file WHERE action_name = 'FAILED_LOGIN' AND event_time > DATEADD(hour, -1, GETDATE());Example Output:
event_time | server_principal_name | client_ip | error_number |
---|---|---|---|
2024-02-04 15:45:22 | unknown_user | 192.168.1.150 | 18456 |
2024-02-04 15:42:15 | test_account | 192.168.1.151 | 18452 |
Analyzing Audit Data
To connect and analyze audit data, use the following SQL queries:
-- Query audit logs for specific time period SELECT table_name, operation_type, modified_by, modification_time, new_value FROM audit_log WHERE modification_time >= NOW() - INTERVAL '24 hours' ORDER BY modification_time DESC;
