A security playbook is a written guide that describes the steps an organisation should follow when handling various security scenarios. It brings together detailed procedures, roles and responsibilities into a single resource so that teams know exactly what to do when an incident occurs.
Within a playbook each scenario, be it detecting suspicious activity or responding to a data breach, is laid out in order. It outlines how to identify the issue, who to notify, which tools to use and how to communicate internally and externally. By having these instructions in advance, the response can begin immediately without confusion or delay.
Using a security playbook helps support consistent handling of incidents across different teams and shifts. It also provides a basis for training exercises and post-incident reviews. Over time the playbook is refined as new threats emerge and lessons are learned, ensuring an organisation’s defences remain up to date.
