Why Is It Important to Have an Incident Response Plan?
You don’t want to discover that you don’t have an Incident Response (IR) plan during a crisis. Not only will having an IR plan allow you to detect, contain, and eradicate incidents more quickly, but it can also help mitigate the financial, reputation, and customer losses that can occur due to an incident.
Controlling communications is perhaps the most complex and essential to responding to an incident. A communications plan outlining roles and responsibilities and who handles any required communications will allow a controlled message that safeguards your company.
Cyber incidents can be devastating both financially and in terms of your company’s reputation. According to Security Intelligence, in a 2021 study, the average total cost of a data breach increased by nearly 10 percent to $4.24 million — the highest ever recorded. This is even worse for our healthcare system. According to Becker Health IT, data breaches in healthcare were the most expensive by industry at $9.23 million on average; that cost increased by $2 million from last year.
Having an IR Plan is the first step to keeping your company, employees, and client information safe. You can be targeted no matter how small or large your business is. Despite every measure you put into place to avoid a data breach, if (or when) a data breach occurs, being prepared means being ready!
What Is an Incident Response Plan?
An incident response plan outlines the people, processes, and technology required to respond effectively during a security breach. Having the right people and procedures in place is critical for dealing with a threat swiftly and successfully. The significant phases of an incident response include preparation, detection, containment, eradication, recovery, and post-incident lessons learned.
A central element of an IR Plan is a communications plan that defines who can say what to whom. It is also worth considering engaging an attorney to provide a guided approach that can leverage attorney-client privilege.
Steps to Take to Get Started
The National Institute of Standards (NIST) documents critical steps to developing an IR Plan. The following are cybersecurity incident response steps you will want to follow:
- Develop an incident response policy, plan, and procedures.
- Define the incident response team structure and services.
- Prepare the team according to the documented procedures, acquire necessary tools, establish incident scenarios, and develop a detection and response process.
- Develop a containment, eradication, and recovery process.
- Define post-incident activities.
In practice, your company should start by assessing current plans and available resources for incident response. Evaluating whether you have the skills and capacity to develop an IR Plan will allow you to determine the best course of action. You may consider a trusted external source for assistance. AISN is here to help and can provide a range of assistance — from working with your team to driving the development of the entire plan.
One last note. It isn’t enough to have a plan. It needs to be communicated, adopted, and practiced! Don’t forget: you wouldn’t just put locks on your house and leave home without locking them. Being prepared means being ready! Even if you think you aren’t a target, you probably are.
Communicating with your team about a potential breach and the steps you took to eliminate the threat can help if that threat returns. Remember, it starts with an informed team to protect the organization’s data.
