In the world of business, we plan for everything. We have marketing plans, sales plans, and financial plans. But what about a plan for when a cyberattack happens? Many small to medium-sized businesses (SMBs) operate under the assumption that a major cyber incident will never happen to them. Unfortunately, that’s a dangerous myth. A recent study found that nearly two-thirds of SMBs experienced a cyberattack in the last year. The truth is, it’s not a matter of if your business will face a cyber incident, but when.

The good news is that you don’t need a team of cybersecurity experts to build a solid foundation. An effective cyber incident response plan (IRP) is a roadmap that guides your team through the chaos of an attack, minimizing damage and getting you back on your feet quickly. The cost of not having a plan can be catastrophic—from data loss and regulatory fines to a complete halt of business operations. Here’s a 5-step guide to help you build your own IRP.

Step 1: Preparation is Everything

An IRP isn’t something you create after the fact; it’s a document that you build and refine before an incident occurs. This is the most crucial step.

• Form a Response Team: Identify the key players on your team. This may include your IT manager (or Krypto IT!), a representative from management, a legal counsel (if possible), and a communications point person. Everyone needs to know their role and responsibilities ahead of time.
• Identify Your Assets: What are your most critical digital assets? This includes customer data, financial records, intellectual property, and key business applications. You can’t protect what you don’t know you have.
• Create a Communication Plan: Who do you need to notify and when? This includes employees, customers, partners, and even law enforcement. Have pre-written email templates and social media posts ready to go to save valuable time during a crisis.
• Establish a “Go-Bag”: Think of this as your emergency kit. It should contain key information, such as contact lists, system diagrams, and backup procedures—all stored securely offline in case your network is compromised.

Step 2: Detection and Analysis

Once an incident occurs, your first priority is to quickly and accurately identify the issue. This is where your preparation pays off.

• Monitor Your Systems: Use tools to monitor your network for unusual activity, such as a sudden increase in data traffic or unauthorized logins.
• Collect Evidence: Once a threat is detected, you need to gather as much information as possible without contaminating the evidence. This includes logs, malware samples, and system data. This information will be vital for understanding the attack and preventing future incidents.
• Determine the Scope: Is the breach limited to a single computer, or has it spread across your entire network? The scope of the attack will dictate the rest of your response.

Step 3: Containment, Eradication, and Recovery

This is the core of your response plan. Your goal is to stop the bleeding, clean up the mess, and restore normal business operations.

• Containment: The immediate priority is to isolate the affected systems to prevent the attack from spreading. This might mean unplugging devices, isolating network segments, or shutting down servers.
• Eradication: Once contained, you can begin to remove the threat. This involves deleting malware, removing compromised accounts, and patching vulnerabilities that were exploited.
• Recovery: When you are confident the threat has been eliminated, you can begin the process of restoring your systems. This includes restoring data from secure backups, bringing systems back online, and verifying that everything is functioning correctly.

Step 4: Post-Incident Review

The incident may be over, but your work isn’t. The lessons learned from an attack are your most valuable tool for strengthening your defenses.

• Hold a “Lessons Learned” Meeting: Bring your team together to discuss what went right and what went wrong during the incident.
• Update Your Plan: Based on your findings, revise your IRP to address any gaps or weaknesses you discovered.
• Enhance Your Defenses: The information from the review should lead to concrete actions, such as implementing stronger security tools, providing additional employee training, or updating your policies.

Step 5: Practice, Practice, Practice

A plan is only as good as its execution. You wouldn’t wait for a fire to practice your fire drill, and the same applies to cybersecurity. Conduct tabletop exercises or simulated attacks at least once a year. This helps your team become comfortable with their roles and responsibilities and uncovers weaknesses in your plan before you have to use it in a real-world scenario.
