Incident response management (IRM) is an increasingly important, and popular, part of cyber security. It enables organisations to avoid the potentially disastrous consequences of disruption by helping them detect incidents promptly and respond appropriately.
Despite its growing prominence, many are still unsure of how IRM works, so we’ve provided four tips to help you get started.
Understand cyber security incidents
You won’t be able to manage incident response effectively if you don’t understand the threats your organisation faces. They come in many guises and each one needs to be managed appropriately. A phishing attack targets a different vulnerability than, say, an electrical fire, so organisations must prepare differently.
Make sure your scope is appropriate
The number of threats you identify will be incredibly long, and, realistically, you won’t be able to handle them all. You should therefore decide which threats to prioritise. Your decision should be based on an assessment of the potential damage of each threat and the likelihood of it occurring.
Create an incident response plan
With your most important threats identified, it’s time to create an incident response plan (IRP) to deal with them. This is a six-step process:
- Preparation: the policies, procedures, governance, communication plans and technological controls you’ll need to continue operations after an incident has occurred.
- Detection: the measures you need to spot incidents promptly.
- Containment: the way you’ll isolate the problem and stop it causing further damage.
- Investigation: how you intend to learn more about the attack and the way it can be resolved.
- Remediation: the process of returning to business as usual.
- Review: the processes for assessing procedural and policy implications, gathering metrics and identifying what lessons need to be learned.
Train your staff
The success of your IRP hinges on how well your staff execute it. The people responsible for creating the plan obviously need to be taught about the importance of cyber security and incident response, but organisations often forget to include other employees. In fact, it’s not uncommon for staff to be unaware that their organisation even has an IRP, so when disaster strikes, they’re not equipped to follow it.
You therefore need to make staff aware of the IRP, why it’s in place and what their responsibilities are.
Become an IRP expert
Those who want to learn more about incident response and how they can become a valued member of their organisation’s planning team should consider our Incident Response Management Foundation Training Course.
This course covers everything you need to know to effectively detect, analyse and respond to a variety of threats. An expert practitioner will guide you through:
- The role of the incident response team;
- Formulating an incident response plan;
- Incident scenarios for common attack vectors; and
- The ways in which an IRP helps you comply with the EU General Data Protection Regulation (GDPR) and the Network and Information Systems (NIS) Regulations.
