In the current threat landscape, it is no longer a matter of if an organization will face a security incident, but when. For business leaders, the transition from a chaotic, reactive stance to a structured, repeatable process is the hallmark of operational resilience. At iExperts, we advocate for the adoption of ISO/IEC 27035, the international standard for information security incident management, as the definitive blueprint for achieving this maturity.

Why ISO 27035 Matters for Modern GRC

While ISO/IEC 27001 provides the high-level framework for an Information Security Management System (ISMS), ISO 27035 zooms in on the granular details of managing vulnerabilities and incidents. It provides a structured approach that ensures nothing is left to chance when a crisis hits. By aligning with this standard, organizations can reduce the financial impact of breaches and maintain the trust of stakeholders.

"True incident response maturity is measured not by the absence of incidents, but by the speed and precision of the response."

The Five Pillars of the ISO 27035 Lifecycle

• Plan and Prepare: Establishing the policy, the Incident Response Team (IRT), and the technical tools required for effective action.
• Detection and Reporting: Implementing robust monitoring to identify anomalies and ensuring a clear path for internal reporting.
• Assessment and Decision: Rapidly evaluating the severity of an event to determine if it constitutes a formal security incident.
• Response: Executing containment, eradication, and recovery strategies while preserving evidence for forensic analysis.
• Lessons Learned: The most critical phase for maturity, where the organization analyzes the response to prevent future recurrences.

Key Deliverables for a Mature IR Program

To move toward full compliance and maturity, iExperts recommends focusing on the following tangible outputs:

• Incident Management Policy
• Standard Operating Procedures (SOPs)
• Post-Incident Report (PIR) Templates
• Continuous Training and Tabletop Exercises

Pro Tip

Automating the initial stages of the lifecycle using a SOAR (Security Orchestration, Automation, and Response) platform can significantly lower your Mean Time to Respond (MTTR), which is a key metric in ISO 27035 auditing.

Achieving excellence in incident management is a journey. By adopting the principles of ISO 27035, your organization ensures that it remains resilient in the face of adversity.
