Yes, you do. Information security breaches are inevitable in today's highly complex and extremely interconnected world. A well-thought-out incident response plan will help to ensure that you have all of the necessary processes and procedures to hunt for threats in your environment, ensure that those threats are properly contained and eradicated, and that you are able to properly restore your organization to a state where business can resume.
Regardless of the size of your organization, you need to ensure that you have a well-thought-out process for how your organization will respond in the event of an information security incident. Of course, the size and complexity of your incident response plan will vary greatly depending on the size and complexity of your organization. Additionally, an incident response plan is not weighed by the pound. Your incident response plan should be concise and to the point.
The incident response plan is key to the success of a well-functioning information security program. The incident response plan ensures that the information security program, IT organization, and business stakeholders have repeatable and agreed upon processes for the following:
- Containing
- Eradicating
- Recovering
These help guard against threats that actively engage your organization.
