Understanding how to craft an effective incident response plan in cybersecurity is paramount in these times where cyber threats proliferate with growing speed and volatility. Responding to these threats in a timely and efficient manner can be the determining factor between an organisation's survival or downfall. In this guide, we will cover the steps required to create a 'simple incident response plan', making it an essential cybersecurity resource.

Introduction

The primary aim of an Incident response plan is to allow organisations to quickly identify, contain, eradicate, and recover from an ongoing cyber attack, mitigating the potential risks and damage. But, how do we create a 'simple Incident response plan'? It may seem like a daunting task, but taking it step by step makes it manageable.

Define a Cybersecurity Incident

Firstly, you must define what a cybersecurity incident is within the context of your organisation. Naturally, not all security events are defined as incidents. A cybersecurity incident can be any event that breaches an organisation's security policies and poses a significant risk to the integrity, confidentiality, or availability of its systems or data.

Establish an Incident Response Team

The second step is to establish a dedicated Incident response team. This team should be composed of a diverse skill set and include staff from various parts of your organisation. The team would typically include IT staff, HR, PR, and Legal teams.

Organise Incident Classification & Prioritisation

Not all cyber incidents are created equal, some may require immediate attention while others are less critical. Having a classification and prioritisation system in place will streamline the Incident response process, by enabling the response team to focus on major incidents first.

Create Incident Response Procedures

Having laid the foundational aspects of your 'simple Incident response plan', the next step is to establish a detailed response procedure. This involves setting out the steps to be followed when an incident is happening, which should be able to guide the Incident response team from the initial detection phase, through reaction, and until recovery is achieved.

Testing and Constant Update

The Incident response plan should never be set in stone; rather, it calls for continuous reviewing, testing, and updating, to ensure its effectiveness against ever-evolving threats. Regular practice scenarios should also be enacted to ensure all members of the Incident response team are familiar with their roles and the procedures to be followed.

Document Incident Analysis and Learn from It

Upon closing an incident, it is important to document what happened, how it was handled, and what can be learned from it. These "post-mortem" analysis reports can provide valuable insights for future incidents and identify areas of improvement in the Incident response process.

In conclusion, creating a 'simple Incident response plan' is not as daunting as it may initially seem. By following these steps, your organisation can be well-equipped with an effective defense mechanism to contain, eradicate, and recover from any potential cybersecurity threats. Because when it comes to cybersecurity, it is not a matter of 'if' but 'when' an incident will occur, and being prepared is always the best offense.
