AIR ISMS Portfolio

ISO/IEC 27001:2022 — Information Security Management System

Aetheria Infrastructure Research (AIR) is a fictional European research organisation created for portfolio purposes. All documents, data, risks, and findings in this repository are simulated. The organisation, its systems, personnel, and government partnerships do not exist.


Overview

This repository contains a complete, end-to-end Information Security Management System (ISMS) portfolio built to the requirements of ISO/IEC 27001:2022. It was developed to demonstrate practical knowledge of the standard, from organisational context and risk assessment through policy development, control evaluation, internal audit, and improvement planning.

The fictional organisation (AIR) is a 145-person critical infrastructure research firm operating across three EU locations (Madrid, Brussels, Riga), handling sensitive research and infrastructure-related data, and developing proprietary AI models. The scenario was chosen to reflect a complex, realistic information security environment (multiple jurisdictions, sensitive data classifications, contractor access risks, and a mix of cloud and on-premises infrastructure).

Certification target (simulated): ISO/IEC 27001:2022 — Q1 2027 Standard clause coverage: All mandatory clauses (4–10) and all 93 Annex A controls assessed

What Each Section Covers

01 — Context and Scope

The foundation of the ISMS. The Organisation Profile documents AIR's internal and external context: governance structure, strategic objectives, regulatory obligations (GDPR, NIS2, EU AI Act), and the threat landscape specific to a critical infrastructure research organisation. The Scope Statement formally defines the ISMS boundary across all three locations, 145 personnel, and 12 systems, with justified exclusions and documented interface controls.

02 — Asset Management

The Asset Inventory catalogues 11 primary information assets (from government-classified research data to AI model weights) and 12 supporting technical assets. Each asset carries an owner, a classification level (Restricted through Public), a CIA impact rating, and links to the risks that apply to it.

03 — Risk Management

The Risk Assessment Methodology defines a 5×5 likelihood-impact matrix, risk appetite thresholds, and the four treatment options available to asset owners. The Risk Register applies this methodology to 13 identified risks across identity and access, data protection, AI infrastructure, and legal compliance domains.

04 — Policies

Three topic-specific policies exist beneath the top-level Information Security Policy:

  • Information Security Policy — management mandate, five measurable security objectives, information classification scheme, and the policy hierarchy
  • Access Control Policy — full access lifecycle with defined timeframes, MFA requirements, Privileged Identity Management, and a contractor access framework
  • Incident Response Policy — P1–P4 severity classification, six-phase response lifecycle, GDPR 72-hour notification obligations, and evidence handling procedures

05 — Operations

A fully scripted tabletop exercise (Operation Stale Key) simulating the exploitation of a stale contractor account to access 4.1 GB of Restricted research data. Six timed injects test the team's detection, classification, containment, legal notification, and media handling capability, with facilitator notes, expected responses, and a structured debrief framework.

06 — Compliance

The Statement of Applicability assesses all 93 ISO/IEC 27001:2022 Annex A controls, none are excluded. 9 are fully implemented, 63 are partially implemented, and 21 are not yet implemented, each with an evidence reference and recommended action. The Internal Audit Report documents a simulated first audit: 2 major non-conformities, 5 minor non-conformities, 5 observations, and 8 conformities, with a full findings log tracking corrective actions and target dates.

07 — Improvement

A 10-month Security Improvement Roadmap across 9 workstreams, covering 48 prioritised initiatives. Includes a 15-gate pre-certification checklist mapping every condition AIR must satisfy before submitting for Stage 1 external audit.


Simulated Certification Pathway
