Data Masking is a core data privacy and protection concept that every cybersecurity and GRC professional should understand.
What Is Data Masking?
Data Masking refers to the practices, processes, or technologies related to data masking within the context of information security and risk management. Understanding data masking helps organizations protect their systems, data, and operations from relevant threats.
How It Works
Data Masking is applied through a combination of policies, technical controls, and organizational procedures. Security teams implement data masking as part of a broader security program aligned to industry frameworks and regulatory requirements.
Why It Matters
Organizations that correctly implement data masking reduce their exposure to cyber risk, improve regulatory compliance, and strengthen their overall security posture.
