ISO 27002 Control 8.33: Key Security Considerations for Test Data
While non-production test environments such as staging environments are essential to building high-quality software products and applications free of bugs or errors, the use of real data and lack of security measures in these environments expose information assets to heightened risks.
For example, developers may use easy-to-remember credentials(e.g “admin” for both username and password) for testing environments in which sensitive data assets are stored.
This may be exploited by cyber attackers to gain easy access to test environments and steal sensitive information assets.
Therefore, organisations should put in place appropriate controls and procedures to protect real-world data used for testing.
Purpose of Control 8.33
Control 8.33 enables organisations to achieve two purposes:
- To protect and maintain the confidentiality of information used in the testing environment.
- Selection and use of test information that will yield reliable results.
Attributes Table of Control 8.33
Control 8.33 is a preventive type of control that requires organisations to select and protect the most appropriate information for the testing stage so as to maintain the confidentiality and integrity of information.
| Control Type | Information Security Properties | Cybersecurity Concepts | Operational Capabilities | Security Domains |
|---|---|---|---|---|
| #Preventive | #Confidentiality | #Protect | #Information Protection | #Protection |
| #Integrity |

Ownership of Control 8.33
Considering that Control 8.33 entails the selection, protection, and management of the most appropriate test information to be used for testing, information security officers, in cooperation with the development team, should be ultimately responsible for establishing appropriate controls and procedures.
General Guidance on Compliance
Organisations should not use sensitive information, including personal data, in the development and testing environments.
To protect the test information against loss of confidentiality and integrity, organisations should comply with the following:
- Access controls applied in real-world environments should also be implemented in test environments.
- Establishing and implementing a separate authorisation procedure for the copying of real information into test environments.
- To keep an audit trail, all activities related to copying and use of sensitive information in test environments should be recorded.
- If sensitive information will be used in the test environment, it should be protected with appropriate controls such as data masking or data removal.
- Once the testing is completed, information used in the test environment should be safely and permanently removed to eliminate the risk of unauthorised access.
Furthermore, organisations should apply appropriate measures to ensure the secure storage of information assets.
Supplementary Guidance on Control 8.33
It is noted that system and acceptance testing may require an enormous amount of test information, equivalent to operational information.

Changes and Differences from ISO 27002:2013
27002:2022/8.33 replaces 27002:2013/(14.3.1)
Although the 2022 version is similar to the 2013 version to great extent, the 2022 Version introduces the following requirement:
- If sensitive information will be used in the test environment, it should be protected with appropriate controls such as data masking or data removal.
The 27002:2013 version, in contrast, did not include this requirement.
