Andrew Pattison, a seasoned expert with over 30 years in information security and risk management, emphasizes the pragmatic nature of ISO 27001 in this interview. He explains that ISO 27001 is often misunderstood as a rigid framework when, in fact, it takes a flexible, risk-based approach. This misconception arises because many implementers prioritize certification, leading them to adopt a “you must do X” attitude, which gives the impression that the standard’s clauses are more rigid than they are. Pattison stresses that organizations can tailor controls based on risk, selecting or excluding controls as needed, provided they can justify these decisions.
He explains that a true risk-based approach to ISO 27001 involves understanding risk as the combination of a vulnerability, a threat to that vulnerability, and the likelihood of that threat being exploited. Organizations often focus on sensationalized, niche technical risks rather than practical issues like staff awareness training, which can be addressed easily and cost-effectively. Pattison advises focusing on risks that have a real-world impact, rather than obscure ones that are less likely to materialize.
To keep risk assessments manageable, Pattison advocates for simplicity. He favors straightforward risk matrices and encourages organizations to focus on what truly matters. According to him, risk management should answer two questions: “What do I need to worry about?” and “How do I address those worries?” Complicated risk assessments, often bogged down by mathematical models, fail to provide clear, actionable insights. The key is to maintain focus on where the real risks lie and avoid unnecessary complexity.
Pattison also believes in actively involving clients in the risk assessment process, rather than conducting it on their behalf. By guiding clients through the process, he helps them develop a deeper understanding of their own risks, linking these risks to their business objectives and justifying the necessary controls. This collaborative approach ensures that clients are better equipped to manage their risks in a meaningful and practical way, rather than relying on third parties to do the work for them.
