A Practitioner's Field Guide
First edition · 2026 · 78 pages

AI is in production. The controls around it were built for a different problem.

Chatbots became copilots, copilots became agents, and agents acquired credentials, tool access and the ability to act on systems of record. Data now moves through normal, correctly-functioning AI operation in ways conventional controls were never designed to see.

A practitioner's field guide that brings the technical, privacy, regulatory, governance and operational dimensions of enterprise AI risk together in one place — with a control library, a ninety-day plan and checklists you can take to work.

The problem

AI changed the shape of the security problem.

Ask an internal assistant to summarise the quarter's underperforming accounts and it retrieves from half a dozen repositories, assembles a context window and returns an answer. No file moved. No perimeter was crossed. No DLP rule fired. Yet a synthesis of material the employee may never have been entitled to see has just been created and delivered.

01

Aggregation without transfer

Fragments from many sources combine into a single answer more sensitive than any one of them. Per-document classification does not capture the combination.

02

Instructions share a channel with data

A model reads its instructions and the content it processes through the same input, with no reliable structural means of telling them apart.

03

Non-determinism

The same input can produce different outputs. Testing establishes a distribution of behaviour, not a guarantee — so "it passed the test" does not transfer.

04

Delegated action

Once a model can call tools, its output stops being text and becomes an instruction to a real system: a database write, an email, a payment, a deployment.

The stakes

The dominant failure mode is the absence of a programme.

Chapter 1 sets out the cost data and reads the governance signal inside it. The organisations paying the premium are, in the main, the ones that deployed AI faster than they governed it.

USD 4.99M

Global average cost of a data breach in 2026, up 12% on the prior year.

1 in 4

Malicious breaches were AI-enabled — a 56% increase year on year — costing roughly USD 6M.

20% → 43%

Share of breached organisations with incidents involving unsanctioned AI tools, year on year.

What's inside

Seventeen chapters, in the sequence a real programme takes.

Five parts: why AI breaks the assumptions behind conventional data security, the threat landscape, privacy as a distinct discipline, the regulatory and standards landscape, and the conversion of all of it into controls.

PART II · CH 3–7

Understand the modern AI attack surface

The OWASP Top 10 for LLM Applications and what changed in 2026 — prompt injection, sensitive information disclosure, excessive agency, supply chain — plus where that list stops. Shadow AI as an ungoverned perimeter, and the retrieval layer's permission-loss problem.

Six case files of documented failures, and the pattern across all of them.

PART II · CH 6

Contain agents before they become operational risk

What changes when a model can act: the identity problem for non-human actors, designing for containment, and the connector and protocol surface.

Tool scope · credentials · approval gates · step and spend ceilings · memory isolation · kill switches.

PART III · CH 8–9

Treat privacy as its own discipline

Why security controls do not discharge privacy obligations. Lawful basis and the training question, purpose limitation and function creep, transparency, data subject rights against an AI system, and accuracy where the system fabricates confidently.

Privacy-enhancing technologies: the categories, choosing one, and a realistic assessment of each.

PART IV · CH 10–12

Turn regulation and standards into obligations

The EU AI Act, India's Digital Personal Data Protection framework, data protection law generally, and the United States. Cross-border transfer, sovereign and regional AI, and sector-specific overlays.

NIST AI RMF and ISO/IEC 42001 — how they fit together, and what none of them cover well.

PART V · CH 13

Build an operating model that survives the business

The accountability question, the four artefacts, the lifecycle gates, and risk tiering so the process survives contact with delivery teams.

Inventory · assessments · control evidence · governance forum with decision authority.

PART V · CH 14–17

Put controls into practice

The control library, the first ninety days, vendor due diligence and contracting, and incident response for AI systems from preparation through notification and recovery.

Plus a glossary, board questions, checklists, a regulatory calendar and a sources appendix.

Not just theory

A control you can name, assign and test.

Every chapter closes with a short set of deliberately concrete actions. Part V is a reference layer: a structured control library organised by the layer each control operates on, each one carrying a priority and a test.

The book's own instruction: test each control rather than declaring it. A control you cannot demonstrate under test is a control you do not have.

Sample control — D1 · P1: enforce authorisation at the retrieval layer, before content enters model context. Test: query from an under-privileged account; confirm no unauthorised content returned.

The first ninety days

Days 1–30, see the estate. Days 31–60, close the loudest gaps. Days 61–90, build the system that persists — plus what to do differently if you are further along.

Procurement and contracting

Where AI enters through procurement, the due diligence questions to ask, terms worth insisting on, and how to assess open-weights and self-hosted options.

Incident response

What an AI incident looks like, then preparation, detection, containment, investigation, notification, recovery and learning.

Ten questions for the board

Appendix B — questions phrased for an executive risk committee, each with a right answer that is a document rather than a reassurance.

Quick-reference material

Things you can take into work on Monday.

Appendix C collects the operational material into checklists — a pre-deployment list, an operating cadence, and the five tests that find the most.

Before deploying any AI system

  • Inventory entry created, owners named
  • Purpose defined; permitted purposes explicit
  • Risk tier assigned against published criteria
  • Data categories identified across all five entry doors
  • Lawful basis documented; privacy assessment if threshold met
  • Retrieval authorisation designed and tested
  • Hidden context reviewed for credentials and authorisation logic
  • Tool scope minimised; approval gates for irreversible actions
  • Step, token and spend ceilings configured
  • Logging with redaction at capture; store classified
  • Adversarial test completed for Tier 2 and above
  • Kill switch documented and tested
  • Provider contract confirms training exclusion, retention, region, incident window
  • Review date set

Abridged from Appendix C

Operating cadence

WeeklyRetrieval, spend and tool-call anomalies; triage staff reports
MonthlyInventory update; new AI features in existing tools; non-human identity register
QuarterlyForum metrics review; policy refresh; red team a rotating system; vendor changes
AnnualFramework mapping refresh; assessment renewal; certification surveillance

The five tests that find the most

  1. The under-privileged query
  2. The revocation test
  3. The ingested injection
  4. The agent scope enumeration
  5. The reconstruction test
Who it's for

Written for the people who have to hold the line.

It assumes no prior background in machine learning. It does assume you are responsible for something.

Security leaders

You need the AI-specific delta: what is new, what is different, and which controls actually address it. Parts II and V are written for exactly that read.

Privacy and compliance officers

Part III treats privacy as a discipline separate from security — lawful basis, purpose limitation, subject rights and assessments against systems that do not hold data the way older ones did.

Risk and internal audit

Every control in the library carries a test, which is what an audit programme needs. Tiering criteria, evidence and lifecycle gates are set out explicitly.

Data and platform engineers

Chapters 2, 5 and 6 go layer by layer: where enterprise data enters and leaves, retrieval authorisation, hidden context, tool scope and agent containment.

AI governance professionals

Chapter 13's operating model, the framework mapping across NIST AI RMF and ISO/IEC 42001, and the artefacts that make accountability demonstrable.

Executives signing off on AI programmes

Appendix B gives ten questions that surface the real state of a programme, each with a right answer that is a document rather than a reassurance.

Not written for: readers looking for an introduction to AI, a prompting guide, or a machine learning textbook.

What you'll be able to do

Thirteen things you will understand differently.

The book is educational material, not legal advice. Regulatory obligations depend on your jurisdiction, sector, corporate role and the specific systems you operate.

  • 01Where enterprise data enters and leaves an AI system
  • 02How retrieval can quietly lose the permissions of its source systems
  • 03Why agency changes the consequence of a model error
  • 04How prompt injection and indirect, ingested attacks work
  • 05Why prohibition drives shadow AI underground, and what works instead
  • 06Why security controls do not discharge privacy obligations
  • 07Which privacy-enhancing technologies are worth the cost, and when
  • 08How to read the EU AI Act and India's DPDP framework against your systems
  • 09Where cross-border transfer and sovereignty constrain deployment
  • 10How NIST AI RMF and ISO/IEC 42001 fit together in one programme
  • 11How to structure accountability, tiering and lifecycle gates
  • 12How to build evidence for audits and customer questionnaires
  • 13How to prepare for, detect, contain and report an AI incident
Where the material comes from

Every figure in the book has a source you can check.

Appendix E lists the primary sources by subject. The book states its own position clearly: figures, framework versions and regulatory dates reflect the position as at August 2026, and three areas — the OWASP GenAI lists, the Commission's implementing guidance, and India's phased DPDP commencement — were under active revision at the time of writing.

Questions

Before you buy

Who is this ebook for?+

Security leads, privacy and compliance officers, risk and audit professionals, data and platform engineers, AI governance professionals, and the executives who sign off on AI programmes.

Do I need a machine learning background?+

No. The book states that it assumes no prior background in machine learning. It does assume you are professionally responsible for something — a system, a control, a programme or a sign-off.

Is this a programming or machine learning book?+

No. There is no code and no model training material. It is architectural and control-oriented: where data flows, where authorisation must live, what to test, and what to write down.

Does it cover agentic AI and RAG?+

Yes — a chapter each. Chapter 5 covers RAG, vector stores and permission loss, including where the control must live. Chapter 6 covers agentic AI: identity, containment, and the connector and protocol surface. Control groups D and F carry the matching controls and tests.

Does it cover the EU AI Act and India's DPDP framework?+

Yes. Chapter 10 covers both, along with data protection law generally and the position in the United States. Appendix D is a consolidated regulatory calendar with the maximum penalties for reference. Dates reflect the position as at August 2026 and the book advises verifying against primary sources.

Does it include checklists and implementation guidance?+

Yes. A control library organised in eight groups, each control with a priority and a test; a ninety-day roadmap; vendor due diligence questions and contract terms; an incident response sequence; ten board questions; and Appendix C's pre-deployment checklist, operating cadence and five tests.

Is this legal or compliance advice?+

No. The book is educational material. It states plainly that regulatory obligations depend on your jurisdiction, sector, corporate role and the specific systems you operate, and that you should engage qualified counsel and your regulator's published guidance before making compliance decisions.

What format is it, and how do I get it after payment?+

A 78-page digital PDF. The flow is: payment on the gateway, automatic redirect to a thank-you page, download from there.

AI adoption is accelerating. The controls around it cannot remain an afterthought.

AI systems read what they are permitted to read, act within the scope they are given, and produce confident output that people and other systems act upon. This field guide sets out how to control the reading, the scope and the output — in one place, with the tests to prove it.
