Your First AI Control Set: Policies, Permissions and Proof

Spinning up an LLM takes a day. Proving you’re using it responsibly - when auditors come knocking, when a customer asks how their data is protected, when a regulator requests documentation that doesn’t exist yet - that takes something entirely different.

Here’s what I’ve seen play out in most organisations: AI adoption starts in pockets. One team uses ChatGPT for marketing copy. Another uses a code assistant. A third is running a vendor pilot. Each team has its own setup, its own risk tolerance, and no shared standards. When a customer asks “how do you protect our data?” or an auditor wants to see AI policies, the organisation scrambles - because there’s nothing consistent to show.

The NIST AI RMF is explicit: controls must be aligned with legal and regulatory requirements. Inconsistency across teams isn’t just an operational headache. It’s a compliance exposure waiting to become a liability.

Start with an authorised tools register

A first control set doesn’t need to be exhaustive. It needs to be real. Start here: a list of AI tools and models that have been reviewed and approved. Every entry gets a business justification, a brief risk assessment, and a designated owner. Unapproved tools are not permitted until they go through the process.

This single control closes the largest gap in most organisations. Not because the register is sophisticated - it doesn’t need to be - but because it replaces the implicit “anything goes” approach with an explicit standard. That shift in posture matters more than any specific rule in the register.

Define role-based permissions

Who can access which models, and what data can those models touch? Map permissions to your existing identity management systems. A junior analyst shouldn’t have the same AI access as your head of finance. Review permissions regularly - quarterly is a reasonable baseline - and update them when roles change. Stale permissions are a silent risk that grows over time.

Log everything - and I mean everything

Log prompts, outputs, and significant decisions made with AI assistance. This isn’t surveillance. It’s the audit trail that makes everything else defensible.

Link logs to your data classifications and risk ratings so that when an incident requires investigation, context is already in place. Logs also surface adoption patterns - which teams are using AI effectively, and which need more support or clearer guidance. That operational intelligence is genuinely useful beyond the compliance function.

Evaluate models and watch for drift

Establish what “good” looks like for each model you deploy, then check it periodically. Document the results. When performance degrades or outputs start drifting from expected behaviour, you want a record that shows you caught it and acted on it.

This feels technical, but the concept is simple: models change over time, and the business changes around them. What worked well six months ago may not work well today. Regular evaluation is how you find out before your customers or auditors do.

Have an incident response plan before you need one

Define what counts as an AI incident - a misleading output acted upon, a data exposure through a prompt, a bias complaint from a customer. Assign owners and response steps. Build in human oversight checkpoints. The first time something goes wrong is not the moment to figure out your escalation path.

Training that actually changes behaviour

Not the checkbox kind. The kind where participants practise on their own tasks, not generic demos. People need to understand what the policies mean in the context of their actual work. Effective training uses real examples, creates space for questions, and recurs as tools and regulations evolve.

The important caveat

Controls shouldn’t become a straitjacket. Don’t burden early-stage experiments with the same governance overhead as a production deployment. Scale controls proportionally as initiatives mature. And encourage teams to report anomalies rather than hide them - a culture where people surface problems is more secure than one where they fear the consequences of raising them.

A minimal, well-implemented control set builds more trust than an elaborate one that exists only on paper. By establishing an authorised tools register, role-based permissions, logging, model evaluation, incident response, and effective training, you demonstrate responsibility - and create the groundwork for confident growth.
