ISO 27001:2022 8.19: Installation of software on operational systems
ISO 27001:2022 8.19 covers Installation of software on operational systems. The held text names 5 evidence records for it, the first being Statement of Applicability entry for control A.8.19, showing inclusion or justified exclusion, implementation status and the risks it.... The common gap an assessor flags is Users can install any software on servers or workstations.
Procedures and measures are to be put in place so that installing software on operational systems is managed securely. Purpose (stated in ISO/IEC 27002:2022): ensures the integrity of operational systems and prevents exploitation of technical vulnerabilities. As an Annex A reference control, it is compared with the controls determined in risk treatment (6.1.3 c) and recorded in the Statement of Applicability as included or excluded, with the justification and implementation status (6.1.3 d); implementation guidance is ISO/IEC 27002:2022 8.19.
What evidence supports 8.19?
- Annex A technological controlStatement of Applicability entry for control A.8.19, showing inclusion or justified exclusion, implementation status and the risks it treats
- Annex A technological controlProcedures for installing and updating operational software, including authorization, testing and rollback planning
- Annex A technological controlChange and deployment records showing management authorization, successful testing and the administrator who performed the installation
- Annex A technological controlConfiguration control records for operational software and documentation, and an audit log of updates
- Annex A technological controlEvidence that development tools and compilers are absent from production systems
Where this requirement comes from
This is our own statement of ISO 27001:2022 8.19, read from the copy we hold (licensed complete copy) and stated in our words, not the standard verbatim. The framework as we hold it.
Common gaps an assessor flags
- Users can install any software on servers or workstations
- Production systems contain compilers and development code
- Unsupported software versions remain in production without a risk decision
- Externally hosted dependencies are pulled at build or run time without integrity controls
How it maps to SOC 2
- CC6.8 high Controlling software installation on operational systems prevents unauthorised software.
A link is a topical overlap with a confidence and a reason. It does not establish that meeting one requirement satisfies the other, and it is not certification.
