Incident response is about addressing and managing the aftermath of a security breach or cyber attack against your business

Since 2013 I have investigated hundreds of security incidents to help my clients minimise the residual risk, understand how the attack has happened and what they can do to minimise the risk of security incidents happening in the future.

Incident response is a coordinated effort to rapidly respond to a security incident in the most efficient, cost-effective manner. The goal of incident response is to quickly identify an attack, minimise its effects, contain the damage, as well as identify and remediate the root cause of the incident to reduce the risk of future incidents.

By having a well-defined IRP, rapid detection and response capabilities, a skilled incident response team, including when appropriare external advisers and consultants, continuous training and testing, and effective communication and collaboration, an organisation can be better prepared to successfully respond to cyber security incidents and minimise their impact.
