In the world of cybersecurity, it is no longer a matter of “if” an incident will occur, but “when.” ISO 27001 has always prioritised being ready for that moment, but the way it asks us to prepare has evolved significantly. If you are shifting from the 2013 version of the standard to the 2022 update, you will notice that the requirements for incident management have been modernised and streamlined under Annex A 5.24: Information Security Incident Management Planning and Preparation.
While the goal of staying resilient remains the same, the structural and qualitative changes in the 2022 version demand a more proactive approach. Let’s break down the key differences and what you need to do to bridge the gap.

Consolidation: From A.16.1.1 to Annex A 5.24
In the 2013 version, incident management preparation was primarily covered by A.16.1.1 (Responsibilities and procedures). It was one of several controls in a somewhat fragmented domain that dealt with reporting, responding, and learning from security events in a more linear, “one-and-done” fashion.
The 2022 update has reclassified this as Annex A 5.24 and moved it into the “Organizational Controls” theme. This isn’t just a simple renumbering; it’s a shift in philosophy. The 2022 standard treats incident management as a continuous cycle of planning and preparation rather than just a set of instructions you follow when something goes wrong. According to the experts at Hightable.io, this change ensures that the organisation maintains a state of constant readiness, making the transition from “business as usual” to “emergency response” seamless.
A Higher Standard for Training and Competence
One of the most noticeable differences in the 2022 version is the increased emphasis on competence. While the 2013 version touched on training, Annex A 5.24 is much more explicit about ensuring that those responsible for managing incidents actually have the skills to do so.
As noted by Hightable.io, the new standard requires organisations to identify the specific training needs of personnel assigned to incident response. This includes not just knowing the policy, but being “battlefield tested” through tabletop exercises and simulations. Auditors now look for evidence that your team has practiced high-pressure scenarios, ensuring that communication and technical responses are second nature before a real breach occurs.
Strengthened Communication and Reporting
In 2013, reporting was often seen as an internal task, telling your boss when a laptop went missing. The 2022 version of Annex A 5.24 broadens the scope of communication significantly. It now places a much heavier emphasis on how you interact with external stakeholders during an incident.
This includes having pre-defined protocols for communicating with:
- Regulatory bodies (like the ICO for GDPR compliance).
- Affected clients and customers.
- Law enforcement or specialized forensic investigators.
- Critical suppliers who may be impacted by your downtime.
The update essentially mandates a “communication matrix” that defines who talks to whom, what they are allowed to say, and how quickly they must say it. This prevents the “panic and pray” response and replaces it with professional, coordinated transparency.
Integration with Modern Detection Tools
While the 2013 standard felt very manual, the 2022 update for Annex A 5.24 acknowledges the modern tech stack. It encourages (and for some, practically necessitates) the use of automated detection and reporting tools. Whether it’s a SIEM (Security Information and Event Management) system or an automated ticketing tool, the standard now expects a “consistent and orderly” reporting mechanism that isn’t just reliant on an employee remembering to send an email.
Hightable.io highlights that an effective transition involves mapping these automated alerts directly to your incident classification levels, ensuring that a “Critical” alert immediately triggers the correct response team without human delay.
Practical Impact: Updating Your Documentation
If you are moving from the 2013 to the 2022 version, you will likely need to overhaul your Incident Response Plan (IRP). It needs to be more than just a policy; it needs to be a functional playbook. Key updates should include:
- Defined Severity Thresholds: Clear criteria for what constitutes a “low,” “medium,” or “high” severity incident.
- Role Handbooks: Brief, actionable guides for different team members (IT, Legal, HR, PR) so they know their specific tasks instantly.
- Evidence Logs: A structured way to capture lessons learned and audit trails, which is now a requirement under the broader incident management theme.
Why the Change is Better for Resilience
The transition to ISO 27001:2022 Annex A 5.24 is about moving from “reactive defense” to “proactive resilience.” By focusing on planning and preparation as a core organizational capability, the standard helps you minimize the reputational and financial damage that inevitably follows a security event.
Ultimately, the 2022 update makes your incident management more professional. For organisations looking to simplify this transition, using the battle-tested incident management templates and tabletop exercise guides from Hightable.io can help you meet the new 2022 standards while genuinely improving your ability to survive a cyber-attack.
