Questions to ask your AI suppliers about data

Most organisations use AI through a supplier, so a supplier's weakness becomes yours. The NCSC tells leaders to understand their supply chains and ask the right questions.

Why it matters

Your data, their systems

The NCSC says leaders should understand their data, model and machine learning software supply chains, and that developers of AI models and systems should take responsibility for the security outcomes their customers rely on, because customers usually lack the expertise to address AI-specific risks [3]. The ChatGPT incident began in an open-source library the service depended on [7].

The questions

Group them by topic

Storage and retention

Where is our data stored, for how long, and can we delete it? Samsung's memo described data on external AI servers as hard to retrieve or delete [8].

Training use

Is our data used to train models, and can we opt out? OWASP lists the ability to opt out of training as good practice [4].

Access

Who at the supplier can read our prompts and outputs, and how is access controlled and logged?

Incident notification

How and how fast will you tell us about an incident? UK GDPR's 72 hour clock runs from the controller's awareness [1], so late notice from a supplier shortens your window.

Secure development

Do you follow recognised guidance? The NCSC's guidelines, developed with CISA and agencies from other countries, cover secure design, development, deployment and operation [2].

Contract points

What to look for

Check these as well:

  • Whether the supplier acts as your processor for personal data
  • Notification terms for incidents and sub-processor changes
  • Deletion on request and at the end of the contract
  • Whether your data is used for training by default
  • Where the data is processed

Put it into practice

Send the questions to each AI supplier and file the answers with your incident plan. Use what to do this week to track the rest.

How CyPro can help

Need a hand working through this?

Finding out whether an incident reaches you is one job. Checking your own systems, tightening access and briefing the board are several more. CyPro's responders and consultants can take any of them on.

Worried this affects you?

If data has leaked through an AI tool or an exposed AI database, the first hours decide how much is lost and what you must report. An incident response team helps you contain it, work out what was exposed and meet your notification duties.
