ASD ISM 0663 Develop and maintain data transfer procedures
What it says
Data transfer processes, and supporting data transfer procedures, are developed, implemented and maintained.
Quoted as published. Everything else on this page is written by Control Stack.
What it means
In plain EnglishEnsure data transfers are securely conducted with proper procedures in place.
This control is about making sure that when you move data from one place to another, it's done safely and securely. If the process isn't secure, sensitive data could be exposed to wrong parties, leading to privacy breaches, financial loss, or damage to your business's reputation.
Free. Save your status, tasks and notes.
Why it matters
Insecure data transfers can leak sensitive information in transit, leading to privacy breaches, legal penalties and reputational harm.
How to implement
IT manager should develop a written plan for data transfers, outlining the specific steps required and tools to use.
This plan should detail how to securely send information, such as using encryption and secure connections.
Office manager should train staff on the new data transfer procedures.
Organise a session where you explain why secure data transfer is important and demonstrate how to follow the procedures correctly.
HR should include data transfer requirements in employee contracts and policies.
Make sure all employees sign off on understanding these procedures as part of their onboarding process.
IT team should regularly update software used for data transfers to ensure security.
This includes installing updates or patches for any tools or platforms used in the process, as outdated systems can be vulnerable to attacks.
Business owner should review the data transfer procedures annually.
You could set a calendar reminder to check if the processes are still effective and make improvements based on any incidents or technological changes.
Keep it running
Maintain documented transfer procedures (methods, encryption, approvals and recipients) and review them regularly to address new threats and changes.
Evidence and audit
- Check 1 of 5What an auditor asks for
Ask for
The documented data transfer procedure manual: Request to see the written guidelines that describe the data transfer process.
Look at
The steps included for their clarity and thoroughness.
Good evidence
Includes a well-organised document that specifies tools, encryption standards, and roles.
- Check 2 of 5What an auditor asks for
Ask for
Training records: Request documentation showing when and how employees were trained on data transfer procedures.
Look at
Dates, names of participants, and training material.
Good evidence
Is a comprehensive list showing regular training sessions attended by all staff.
- Check 3 of 5What an auditor asks for
Ask for
Records showing that data transfers were checked for compliance with the procedures.
Look at
The frequency of audits and any actions taken from findings.
Good evidence
Is an audit log showing timely reviews and documented responses to any issues found.
- Check 4 of 5What an auditor asks for
Ask for
IT maintenance logs: These should detail updates and patches applied to software used for data transfers.
Look at
The timing and frequency of updates.
Good evidence
Is a log showing regular updates in line with the latest security recommendations.
- Check 5 of 5What an auditor asks for
Ask for
A policy review schedule: Request the timeline or calendar for reviewing and updating data transfer procedures.
Look at
Evidence that reviews are planned and happen consistently.
Good evidence
Includes a clear schedule with past and future review dates.
Mappings
Closest match in ISO/IEC 27001: A.5.14, Information transfer policies and procedures, which asks for the same thing.
ISO/IEC 27001: 1 mapping
This control is equivalent to A.5.14.
Annex A 5.14 requires rules, procedures, or agreements to govern secure information transfer internally and with external parties. ISM-0663 directly requires that data transfer processes and supporting procedures are developed, implemented, and maintained. Both controls focus on establishing and maintaining formalised information transfer procedures across transfer methods, with very similar intent and scope.
Mappings show how controls relate across frameworks. They do not imply full equivalence or certification.
