ISO 27001 A.8.19 Installation of Software on Operational Systems Checklist
A.8.19 Installation of Software on Operational Systems within ISO 27001:2022 focuses on ensuring that the installation of software on operational systems is controlled and managed to prevent unauthorised or harmful software from being introduced.
This control aims to maintain the integrity, security, and functionality of operational systems. This comprehensive guide will delve into the key aspects of this control, common challenges a CISO may face during its implementation, and provide a detailed compliance checklist. Additionally, we will highlight how ISMS.online features can be leveraged to demonstrate compliance effectively.
Scope of Annex A.8.19
ISO/IEC 27001:2022 is an internationally recognised standard for Information Security Management Systems (ISMS). It provides a systematic approach to managing sensitive company information, ensuring it remains secure. Annex A of ISO 27001:2022 outlines specific controls that organisations should implement to mitigate risks and safeguard their information assets. Among these, control A.8.19 addresses the installation of software on operational systems, ensuring that only authorised, secure, and verified software is installed to maintain system integrity and security.
Implementing this control is critical as unauthorised or malicious software can compromise system security, leading to data breaches, operational disruptions, and financial losses. Therefore, organisations must establish robust processes for software approval, verification, documentation, and change management. This guide will cover these processes, the challenges a CISO might face, and practical solutions to overcome them.

Why Should You Comply With Annex A.8.19? Key Aspects and Common Challenges
Approval Process
- Solutions: Streamline the approval workflow to make it as efficient as possible, and provide clear communication about the importance of this process in maintaining system security.
- Related ISO 27001 Clauses: Clause 5.3 (Organisational roles, responsibilities, and authorities), Clause 7.5 (Documented information)
Challenges: Ensuring that all stakeholders adhere to the formal approval process can be difficult, especially in large organisations with complex structures. Resistance to additional layers of approval from various departments can slow down the process.
Verification and Validation
- Solutions: Implement automated tools for software verification and validation, and establish a robust testing environment that mirrors the operational systems to avoid disruptions.
- Related ISO 27001 Clauses: Clause 8.1 (Operational planning and control), Clause 8.2 (Information security risk assessment)
Challenges: Verifying the authenticity and integrity of software before installation can be complex, especially when dealing with third-party software or open-source tools. Ensuring thorough testing without impacting operational timelines is another challenge.
Documentation
- Solutions: Utilise centralised documentation management systems and automate record-keeping where possible. Regular audits and training can reinforce the importance of accurate documentation.
- Related ISO 27001 Clauses: Clause 7.5 (Documented information), Clause 9.2 (Internal audit)
Challenges: Maintaining detailed and up-to-date records of all software installations can be labour-intensive. Ensuring that documentation practices are followed consistently across the organisation can be challenging.
Change Management
- Solutions: Foster a culture that embraces change management as a critical component of operational security. Use collaboration tools to enhance communication and coordination between teams.
- Related ISO 27001 Clauses: Clause 8.3 (Information security risk treatment), Clause 6.1.3 (Actions to address risks and opportunities)
Challenges: Integrating software installation into the change management process requires alignment between different teams and departments. There can be resistance to change, especially if it impacts productivity.
Security Measures
- Solutions: Implement continuous monitoring and automated security tools to detect and mitigate threats in real-time. Regularly update security protocols and conduct training sessions to keep staff informed.
- Related ISO 27001 Clauses: Clause 6.1.4 (Information security risk treatment), Clause 7.2 (Competence), Clause 7.3 (Awareness)
Challenges: Keeping up with the latest security threats and ensuring that all security measures are up-to-date can be overwhelming. Ensuring that all installations are free from malware and vulnerabilities requires constant vigilance.
Compliance
- Solutions: Use compliance management tools to stay up-to-date with regulatory requirements and integrate compliance checks into the software installation process. Regular compliance audits can help identify and address any gaps.
- Related ISO 27001 Clauses: Clause 9.3 (Management review), Clause 10.1 (Nonconformity and corrective action)
Challenges: Ensuring that all software installations comply with relevant regulatory and organisational policies can be complex, especially with evolving regulations and standards. Maintaining compliance across multiple jurisdictions adds another layer of difficulty.
