Introduction to Clause 6.11.3: Safeguarding Test Data
Test data (whether dedicated or sourced from an operational environment) needs to be closely managed and logged, to ensure that privacy information is not used inappropriately, or compromised in any way when moving from one environment to another.
What’s Covered in ISO 27701 Clause 6.11.3
ISO 27701 6.11.3 contains one sub-clause that deals with the protection of test data (ISO 27701 6.11.3.1).
There are no additional PIMS or PII-specific guidelines to adhere to, and a single UK GDPR article to consider alongside guidance from ISO 27002 (see below).
Please note that GDPR citations are for indicative purposes only. Organisations should scrutinise the legislation and make their own judgement on what parts of the law applies to them.

Organisations should carefully select test data to ensure that testing activity is both reliable, and secure. Organisations should pay extra attention to ensuring that PII is not copied into the development and testing environments.
In order to protect operational data throughout testing activities, organisations should:
- Utilise a homogenous set of access control procedures across testing and operational environments.
- Ensure that authorisation is required every time operational data is copied to a test environment.
- Log the copying and use of operational data.
- Safeguard privacy information through techniques such as masking (see ISO 27002 Control 8.11).
- Removing operational data from a testing environment, once it’s no longer needed (see ISO 27002 Control 8.10).
- Securely store test data, and ensure that employees are aware that it is only to be used for testing purposes.
