Self-led training Module 2 - Data Masking - Introduction

Masking databases with Curiosity Software

Introduction

Data masking involves replacing sensitive information in databases with fabricated, yet realistic data, thereby protecting the actual data while still enabling the use of the database system for various tasks such as software testing, development, user training, or data analysis. This ensures sensitive data, including Personally Identifiable Information (PII) and commercially sensitive data, remains inaccessible to unauthorised users, minimising the risk of data breaches especially during non-production activities where full security measures may not be implemented.

Additionally, database masking is crucial for regulatory compliance, as many industries are subject to regulations like HIPAA, PCI DSS, and GDPR that mandate the protection of sensitive customer data. Non-compliance can result in substantial fines and reputational damage, making database masking essential for businesses to meet these requirements and protect stakeholders. 

Training Overview:


This training course will take you through the journey of creating a data masking activity using a data dictionary and connection which have already been scanned with PII identified. This is shown visually below as a process diagram:


By the end of this self-led training you will be able to:

  • Mask a database
  • Mask multiple databases keeping referential integrity
  • Expose masking routines to be run how you would like

Prerequisites for the Masking training course:

For this data activity, you will need:
