With such high volumes of attacks, it's crucial that organisations have effective incident response measures in place to mitigate the damage they cause and prevent further attacks.
In this blog, we explore the importance of having a strong Incident Response Plan, and how you can ensure it will stand up in the event of an incident.
What Is an Incident Response Plan?
An Incident Response Plan is a detailed set of instructions that outline the steps an organisation should follow in response to a security incident. This plan should cover all aspects of incident response, including preparation, identification, containment, eradication, and recovery. It should also outline the roles and responsibilities of everyone involved in the incident response process.
The Importance of Having a Strong Incident Response Plan
Having a strong Incident Response Plan in place can make all the difference in the event of an incident. They can help your organisation:
Minimise damage - A well-designed Incident Response Plan can minimise the damage caused in the event of a security incident as it allows you to respond quickly and effectively, limiting the extent of the incident and data compromised.
Maintain business continuity - By having a suitable plan in place, your organisation can quickly get back to business as usual as soon as possible following an incident, minimising the impact on your workforce, customers and stakeholders.
Helps with compliance -Incident Response Plans are required in order to achieve compliance with various standards including the GDPR (General Data Protection Regulation) and PCI DSS (Payment Card Industry Data Security Standard).
Mitigate reputational risk - By responding quickly and containing the impact of a security incident, your organisation can demonstrate to customers and stakeholders that your organisation takes data privacy and security seriously.
How to Evaluate Your Incident Response Plan
There are several ways you can evaluate your Incident Response Plan:
Review Your Incident Response Plan Regularly
Your plan should be reviewed and updated regularly to ensure that it is up-to-date and still relevant to your business operations. Changes in business practices, technology or the threat landscape could make your current plan obsolete.
Have Clearly Defined Roles and Responsibilities
Everyone involved in the incident response process should have clearly defined roles and responsibilities, and be aware of these ahead of having to respond to an incident. This helps ensure that all the incident response measures are coordinated and carried out efficiently.
Test Your Incident Response Plan
Cyber Incident Tabletop Exercises are commonly used by organisations as a way to test their current incident response procedures, processes and policies. By running through scenarios in a controlled environment, these exercises are a great way to identify any gaps or weaknesses in an organisation’s existing Incident Response Plans and develop better strategies for responding to an incident.
Incorporate Lessons Learned
After Cyber Incident Tabletop Exercises and real-life security incidents, it's essential to review what worked and what didn't work. Incorporating lessons learned into your plans can help improve your response to future incidents.
Where to Start With Your Incident Response Planning
Developing an effective Incident Response Plan can be challenging, especially for organisations that lack the resources and internal expertise.
Your Incident Response Plan can make or break your organisation in the event of an incident, so it’s vital that your plans are tailored specifically to your organisation, have been tested, and are robust enough to withstand an incident.
