Data Leakage

What is Data Leakage?

The unauthorized transmission of data from within an organization to an external destination, whether intentional or accidental.

Each of these is named in at least one of the same controls as data leakage. The number is how many controls name both.

What the standards actually require on data leakage

Questions people ask about data leakage

What is Data Leakage?
The unauthorized transmission of data from within an organization to an external destination, whether intentional or accidental.
Why is Data Leakage important for compliance?
Data Leakage is a key concept in Information Security. Understanding data leakage helps organizations meet regulatory requirements, reduce risk, and demonstrate due diligence during audits. Our compliance platform maps 686 frameworks with 311K cross-framework control mappings.
Which compliance frameworks address Data Leakage?
Data Leakage appears in the requirement text of ISO 27001:2022, ISO 27002:2022, ISO/IEC 27011:2024, ASIC Cyber Resilience Good Practices, EIOPA Guidelines on ICT Security and Governance (EIOPA-BoS-20/600). Across these standards we have identified 6 controls that name it directly, each linked to the control text on the compliance platform.
