Assign System Ownership for Better Oversight
Every system should have a specific person responsible for managing it.
Plain language
Every system in your organisation needs someone in charge of it. Think of it like assigning a captain for each ship. This matters because when no one is responsible, issues like security holes can slip through the cracks, leading to data loss or costly downtime.

System ownersOfficial control statement
Each system has a designated system owner.
Why it matters
Without a designated system owner, accountability falters, leaving systems vulnerable to unchecked security gaps and unmanaged incidents.
Operational notes
Maintain a system ownership register and review it quarterly; update the named owner and delegations when staff or responsibilities change.
Implementation tips
- System owners should be assigned by the manager responsible for business operations to take charge of each system. Identify someone who understands the system well and can oversee its management and protection effectively.
- The system owner should document what the system does, who uses it, and how it supports the business. They can do this by listing the system's primary functions, users, and business applications in a simple document.
- The IT team should support the system owner by providing technical details about software updates and security patches. This can involve regular meetings or reports summarising recent changes and any risks identified.
- System owners should work with HR to ensure they have the necessary training and support in cybersecurity practices. They can accomplish this through workshops or online training courses focused on cybersecurity awareness.
- Each system owner should hold regular meetings with their team to discuss any issues or updates related to their system. These meetings should include a brief review of security logs and user feedback to identify any unusual activity or user experience issues.
