Risk Assessment and Treatment in AI and Machine Learning Environments: A Guide to ISO 27001:2022 and ISO 27002:2022

Jram February 20, 2025

Artificial Intelligence (AI) and Machine Learning (ML) are transforming industries, enabling innovation and efficiency. However, these technologies also introduce new security risks, such as data breaches, adversarial attacks, and model manipulation. To address these challenges, organizations can leverage the ISO 27001:2022 and ISO 27002:2022 frameworks. This article explores how these standards can help secure AI and ML environments, the risks organizations face, and actionable mitigation strategies.  

Risk Assessment and Treatment Approach

  1. Risk Identification
    • Objective: Identify risks specific to AI and ML environments.
    • Examples:
      • Data poisoning: Attackers manipulate training data to corrupt ML models.
      • Model theft: Unauthorized access to proprietary ML models.  
      • Adversarial attacks: Inputs designed to deceive ML models.
      • Privacy breaches: Exposure of sensitive data used in AI/ML systems.
  2. Risk Analysis:
    • Objective: Assess the likelihood and impact of identified risks.
    • Tools: Use risk assessment frameworks like FAIR (Factor Analysis of Information Risk) or OCTAVE. 
    • Example: A data poisoning attack could lead to incorrect predictions, causing financial losses and reputational damage.
  3. Risk Evaluation
    • Objective: Prioritize risks based on their severity.
    • Example: A high-impact risk like model theft may require immediate attention, while a low-impact risk like minor data leakage may be addressed later.
  4. Risk Treatment
    • Objective: Implement controls to mitigate risks.
    • Strategies:
      • Avoid: Discontinue high-risk AI/ML projects.
      • Reduce: Implement technical and organizational controls.
      • Transfer: Use cyber insurance to cover potential losses.
      • Accept: Acknowledge low-impact risks that are not cost-effective to mitigate.  
How ISO 27001:2022 Improves AI/ML Security 
ISO 27001:2022 provides a structured framework for managing information security risks, including those in AI and ML environments. Here’s how it helps:  
  1. Holistic Risk Management:
    • Identifies and addresses risks across people, processes, and technology.
  2. Continuous Improvement:
    • Encourages regular reviews and updates to the ISMS to adapt to new threats.
  3. Compliance:
    •  Helps organizations meet regulatory requirements for AI/ML systems (e.g., GDPR, CCPA). 
Risks and Challenges in AI/ML Security 
  1. Data Integrity Risks:
    • Challenge: Attackers can manipulate training data to corrupt ML models.
    • Mitigation: Use data validation techniques and implement access controls.
  2. Model Security Risks: 
    • Challenge: ML models can be stolen or reverse-engineered.
    • Mitigation: Encrypt models and restrict access to authorized users. 
  3. Adversarial Attacks: 
      • Challenge: Attackers can craft inputs to deceive ML models. 
      • Mitigation: Use adversarial training and robust model testing.
  4. Privacy Risks:
    • Challenge: Sensitive data used in AI/ML systems can be exposed.  
    • Mitigation: Implement data anonymization and encryption. 
  5. Lack of Explainability:
    • Challenge: Complex AI/ML models can be difficult to interpret, leading to trust issues.
    • Mitigation: Use explainable AI (XAI) techniques to improve transparency.  

Mitigation Strategies with ISO 27002:2022 Controls
ISO 27002:2022 provides detailed guidance on implementing security controls. Here’s how it can address AI/ML risks:  

  1. A.5.1 Policies for Information Security
    • Objective: Establish clear policies for securing AI/ML systems.

  2. A.5.9 Inventory of Information and Other Associated Assets
    • Objective: Maintain an inventory of AI/ML assets.
    • Application:
      • Identify and document all AI/ML models, datasets, and infrastructure.
      • Regularly update the inventory to reflect changes in the AI/ML environment.
  3. A.5.12 Information Classification
    • Objective: Classify information based on sensitivity.
    • Application:
