ISO 27001 Annex A 8.30 Management of outsourced system development
What it says
The organization shall direct, monitor and review the activities related to outsourced system development.
Quoted as published. Everything else on this page is written by Control Stack.
What it means
In plain EnglishEnsure your organisation oversees and checks outsourced development to maintain security.
When your organisation hires someone else to develop software systems, you must make sure they're doing it securely. If you don't watch over this process, your business could end up with software that exposes you to data leaks or cyberattacks. That's why it's important to check that the people developing your software are doing it to the right standards and securely handling any sensitive information.

Why it matters
Without oversight, outsourced development can introduce security flaws, leading to hidden vulnerabilities and increased supply chain risks.
How to implement
The procurement manager should set clear contractual terms for outsourced development, including security requirements.
This means writing agreements that specify the need for secure design, coding, and testing based on ISO 27002:2022 guidance and relevant Australian regulations like the Privacy Act 1988.
The IT manager should regularly monitor the outsourced development process.
This can be done by scheduling frequent progress meetings and requesting evidence of testing and security practices from the developers to ensure they're following the agreed standards.
The legal team should review licensing agreements and intellectual property rights.
Ensure that the contracts give your organisation access to the source code and the right to audit the development process to protect against supplier bankruptcy.
The compliance officer should ensure the development processes meet regulatory requirements.
This involves understanding the legal obligations under Australian laws such as CPS 234 and ensuring developers adhere to them through security and performance benchmarks.
The security team should conduct acceptance testing for deliverables before completion.
Make sure to review the software for vulnerabilities and confirm all security features are functioning as intended by engaging both internal testers and independent third parties if needed.
Keep it running
Set security requirements in contracts, track supplier KPIs, and review deliverables (code, tests, fixes) via defined reporting and audits.
Evidence and audit

The security clauses and intellectual property terms. Good means these documents explicitly mention security practices and rights to audit.
- Check 2 of 5What an auditor asks for
Ask for
Records of progress meetings between your organisation and the developers.
Look at
Meeting minutes and changes in the development approach.
Good evidence
Documented discussions about security and adjustments made in response to issues.
- Check 3 of 5What an auditor asks for
Ask for
The results of security testing on the developed systems.
Look at
Test reports and vulnerability scans. Good shows comprehensive testing results with action taken on identified weaknesses.
- Check 4 of 5What an auditor asks for
Look at
Documentation of past projects and security certifications. Good indicates the supplier is trusted and experienced in secure system development.
- Check 5 of 5What an auditor asks for
Ask for
Proof of auditing rights and any audits conducted.
Look at
Audit reports and risk assessments done on the supplier's processes. Good means regular audits occurred, and issues were addressed promptly.
Mappings
Closest match in ASD Information Security Manual: ISM-0401, Implement secure by design in software development, which partially overlaps with this control.
ASD Information Security Manual: 10 mappings
This control partially overlaps ISM-0401.
ISM-0401 requires embedding Secure by Design into both internal and outsourced SDLC processes. ISO/IEC 27001:2022 Annex A 8.30 mandates oversight of outsourced development activities, creating overlap where Secure by Design must be enforced contractually. However, Annex A 8.30 centres on supplier management.
This control partially overlaps ISM-0731.
Annex A 8.30 requires the organisation to direct, monitor and review outsourced system development activities so security is maintained when development is performed externally. ISM-0731 requires CISO oversight of cyber supply chain risk management, which includes governance of risks introduced by outsourced developers and their dependencies. ISM-0731 is broader across supply chain risk domains beyond development delivery, while Annex A 8.30 is specifically focused on managing outsourced development execution and oversight.
This control partially overlaps ISM-1395.
Annex A 8.30 requires directing, monitoring and reviewing outsourced system development to ensure security requirements are met by external developers. ISM-1395 requires service providers (including subcontractors) to provide an appropriate level of protection for data entrusted to them, which is often a key requirement in outsourced development arrangements. Annex A 8.30 is centred on controlling development activities and outcomes, whereas ISM-1395 is centred on data protection obligations irrespective of whether development is occurring.
This control partially overlaps ISM-1452.
Annex A 8.30 requires directing, monitoring and reviewing outsourced system development, which inherently involves managing third-party delivery risk. ISM-1452 requires performing a supply chain risk assessment for suppliers of systems, applications, equipment and services, which includes assessing risks associated with outsourcing development to a supplier. ISM-1452 is broader (covering many supplier types and impacts to a system's risk profile), while Annex A 8.30 is more operationally focused on oversight of outsourced development activities once sourced.
This control partially overlaps ISM-1738.
Annex A 8.30 requires directing, monitoring and reviewing outsourced system development activities on an ongoing basis. ISM-1738 supports this by requiring the organisation to regularly exercise its right to verify service provider compliance with security requirements, providing concrete assurance activities that feed monitoring and review. ISM-1738 is limited to exercising contractual verification rights, while Annex A 8.30 also includes setting direction and broader oversight of development practices and outputs.
This control partially overlaps ISM-1780.
ISM-1780 requires SecDevOps practices to be used for software development, including embedding security controls into build, test, and release activities regardless of who performs the development. Annex A 8.30 requires the organisation to direct, monitor and review outsourced system development, which overlaps where SecDevOps requirements (security testing, code integrity, pipeline controls) must be flowed down to vendors and verified. Annex A 8.30 is supplier-governance focused, while ISM-1780 is delivery-practice focused and applies equally to in-house development.
This control partially overlaps ISM-1791.
Annex A 8.30 requires the organisation to direct, monitor and review outsourced system development activities to maintain security and quality. ISM-1791 strengthens this by requiring integrity assessment as part of acceptance of delivered products and services, which is a practical review/assurance step for outsourced development deliverables. ISM-1791 focuses on acceptance testing and integrity verification, while Annex A 8.30 covers broader governance across the outsourced development lifecycle (direction, ongoing monitoring, and review).
This control partially overlaps ISM-1826.
ISM-1826 requires choosing server application vendors that demonstrate secure design and secure programming practices, including preference for memory-safe languages. Annex A 8.30 requires the organisation to direct, monitor and review outsourced system development activities. They overlap where server applications are custom-built or developed by vendors on the organisation's behalf, but ISM-1826 focuses on vendor selection criteria whereas Annex A 8.30 is about governance and oversight of the development work regardless of the vendor's secure-by-design maturity.
This control partially overlaps ISM-2033.
ISM-2033 requires software security requirements to be documented, stored securely, and maintained throughout the SDLC. This overlaps with Annex A 8.30 because directing and reviewing outsourced development commonly includes ensuring security requirements are captured, controlled, versioned, and kept current between the organisation and supplier. Annex A 8.30 is specifically about governance of the supplier's development activities, while ISM-2033 applies regardless of whether development is in-house or outsourced and focuses on the requirements artefacts themselves.
This control supports ISM-0402.
ISM-0402 requires comprehensive vulnerability testing (SAST, DAST, SCA) before release and periodically to identify previously unknown vulnerabilities. Annex A 8.30 requires the organisation to direct, monitor and review outsourced development activities, which can be used to mandate and evidence that suppliers perform the SAST/DAST/SCA testing required by ISM-0402. Annex A 8.30 is governance over third parties, while ISM-0402 is the specific technical assurance outcome to be achieved regardless of who develops the software.
ASD Essentials for enterprise IT: 1 mapping
This control partially overlaps IT.GOV-11.2.
IT.GOV-11.2 requires ongoing assurance that suppliers continue to meet their cyber security commitments, with action taken when assurance lapses or supplier risk changes. Where the supplier performs system development, that assurance forms part of the monitoring and review of outsourced development activities required by ISO/IEC 27001 Annex A 8.30. IT.GOV-11.2 covers all suppliers, while Annex A 8.30 is limited to outsourced system development and also requires the organisation to direct that work.
