Annex A 8.19 verified ISO/IEC 27001:2022
Secure Software Installation Procedures
Ensure software installations are controlled to prevent security risks.
record_voice_over
Plain language
This control is about making sure that whenever software is installed on company computers, it's done in a way that keeps everything safe and secure. If this isn't done properly, it could lead to vulnerable systems that hackers could exploit, which might result in stolen data or disrupted operations.

Why it matters
Without controlled software installation, unauthorised apps can introduce security holes and malware, risking data breaches and operational failures.

Operational notes
Only install approved, signed software from trusted repositories; require change approval, least-privilege installers, and log installs with tested rollback/uninstall steps.

Implementation tips
- The IT manager should ensure that only approved and trained staff can install or update software. This can be done by setting strict permissions on user accounts to limit who can install software, following policies and procedures aligned with ISO 27002:2022.
- The operations team should establish a process for authorising software updates, in which changes are reviewed and approved by management. Use a checklist or system to document the request, approval, and proof of testing, referencing Australian regulations like CPS 234.
- IT staff should conduct thorough testing of software updates before implementation. Set up a testing environment where new software can be trialed to identify potential issues, ensuring alignment with secure configurations as per ASD Essential Eight.
- The IT department should maintain an up-to-date inventory of all software versions used. Use a software management tool that tracks versions, update histories, and ensures compliance with the Privacy Act 1988 regarding data collection and use.
- Managers should ensure a fallback plan is ready in case of failed installations. Create a rollback strategy that includes backing up current software states so you can quickly restore systems if something goes wrong during updates.
03 - Audit
fact_check
Audit / evidence tips
- AskRequest access to the list of personnel authorised to install software. GoodAll listed individuals should have clear approval records and relevant training documentation.
- AskAsk for the documentation process of software update authorisations. GoodThe records should show a clear chain of command with every update authorised by management.
- AskRequest evidence of software testing procedures. GoodTesting logs should demonstrate rigorous processes, noting any issues identified and resolved.
- AskRequest an inventory of current software versions. GoodThe inventory should be complete, accurately reflecting what is in use, and include update histories.
- AskAsk for documentation of rollback plans for software installations. GoodThere should be explicit plans detailing how to revert installations, protecting data integrity during software failures.
