Manage Data Compliance for IBM Netezza

Managing data compliance effectively in IBM Netezza includes components such as ongoing auditing, active data masking, precise data identification, strong security measures, and strict adherence to regulatory standards. This article outlines a practical framework for leveraging these elements to enhance data protection and simplify compliance processes. Explore additional insights into Data Compliance and Regulatory Compliance.

Introduction

Companies utilizing IBM Netezza for complex analytics tasks must carefully handle sensitive information to remain compliant with strict regulations. An effective data management strategy lowers potential risks, guarantees compliance, and boosts business productivity. This guide provides detailed steps to establish effective data compliance tailored specifically for IBM Netezza environments.

Real-Time Audit Implementation with IBM Netezza Tools

Continuous audit processes actively monitor user activities and executed queries. IBM Netezza's Advanced Query History tool provides detailed tracking and extensive logging capabilities.

Audit Setup Steps:

1. Create a user designated for audit tasks:

CREATE USER audituser WITH PASSWORD 'password';
GRANT CREATE DATABASE TO audituser;

1. Set up a dedicated database for audit history:

nzhistcreatedb -d auditDB -t query -v 1 -u audituser -o audituser -p password

1. Define audit configuration parameters:

CREATE HISTORY CONFIGURATION all_hist HISTTYPE QUERY DATABASE auditDB USER audituser PASSWORD 'password' COLLECT QUERY,COLUMN LOADINTERVAL 5 LOADMINTHRESHOLD 4 LOADMAXTHRESHOLD 20 STORAGELIMIT 40 LOADRETRY 0 VERSION 1;
SET HISTORY CONFIGURATION all_hist_on;

1. Restart the IBM Netezza system:

su - nz
nzstop
nzstart

1. Validate the audit setup:

SELECT SESSIONID, DBNAME, TABLENAME FROM AUDITDB.AUDITUSER."$hist_table_access_1";

These auditing features facilitate forensic analysis and adherence to regulations such as GDPR, HIPAA, and PCI DSS. Additional insights can be gained from exploring Audit Trails and Database Activity History.

Dynamic Data Masking

Active data masking safeguards sensitive data in real-time without modifying the original records. IBM Netezza implements dynamic masking through encryption approaches:

Example Masking Setup:

CREATE VIEW nz_masked_vw AS
SELECT
  usr_id,
  usr_login,
  usr_email,
  '****' || SUBSTR(usr_phone, LENGTH(usr_phone)-3, 4) AS usr_phone_masked,
  SUBSTR(usr_card, 1, 4) || '-****-****-' || SUBSTR(usr_card, LENGTH(usr_card)-3, 4) AS usr_card_masked
FROM nz_sensitive_data;

SELECT * FROM nz_masked_vw;

This ensures sensitive information remains protected from unauthorized access, as explained in the IBM Dynamic Data Masking documentation. Further details on masking techniques are available under Data Masking Types.
