Incident Response Plan Template: What to Do When You Get Hacked (Minutes Matter)

If you run a business in Denmark, you probably haven't spent a lot of time thinking about what happens the moment your systems get attacked. That's actually a problem. A lot of companies operate under the assumption that a cyberattack is something that happens to other people, to bigger targets, to organizations they don't know. The reality is different. Every business connected to the internet is a potential target, and the question isn't whether you'll face a security incident—it's whether you'll be prepared when you do.

An incident response plan cybersecurity framework isn't some luxury item reserved for Fortune 500 companies or banks. It's a practical tool that every business needs. When a cyberattack happens, minutes matter. The difference between a contained incident and a catastrophic one often comes down to whether your team knows exactly what to do in those critical first moments. This guide walks you through building a real, actionable incident response plan that your organization can actually use when pressure is highest.

Why You Need an Incident Response Plan Before You Need One

Let's be direct: waiting until after you're attacked to figure out who does what is a losing strategy. Most companies that aren't prepared waste their first crucial hours trying to understand what just happened, arguing about who should handle it, or worse, destroying evidence while they panic.

A solid incident response plan cybersecurity approach means you've already made the hard decisions. You know who calls whom. You know what data matters most. You know whether you're going to involve external experts immediately or try to handle it internally. You've already thought about communication strategies for your employees, customers, and potentially regulators.

The statistics back this up consistently. Organizations with documented incident response procedures recover faster, lose less data, and face smaller financial consequences. For a small to mid-sized Danish business, that might mean the difference between a contained breach affecting a few systems versus a company-wide shutdown that costs 50,000 DKK or more per day in lost productivity.

The Five Phases of Incident Response: What Your Plan Should Cover

Every serious incident response plan cybersecurity framework follows a similar structure. Think of these phases as your playbook—you move through them sequentially, though sometimes you'll loop back.

Phase 1: Detection and Analysis

This is where everything starts. Someone notices something wrong. Maybe your IT team sees unusual network traffic. Maybe an employee reports that their login credentials aren't working. Maybe a customer calls to say they received a suspicious email pretending to be from your company.

Your plan needs to spell out exactly how detection happens. Do you have monitoring systems in place? What alerts trigger a response? Who gets notified first? In a typical Danish company, this might be your IT manager or a designated security contact. That person's job is to immediately validate whether this is actually a security incident or a false alarm.

Validation is critical because not every alert means you've been breached. You want to avoid both extremes—missing a real attack because you dismissed it too quickly, and mobilizing your entire organization because someone forgot their password.

Phase 2: Containment and Isolation

Once you've confirmed an actual incident, the immediate goal is to stop the bleeding. Stop the attacker from accessing more systems. Prevent data from leaving your network. Isolate infected devices.

Your incident response plan should identify which systems are most critical. Which databases contain customer information? Which systems run your core business operations? If you run an e-commerce business, your payment processing systems get isolated and protected first. If you manage employee records, that's priority two. You're essentially creating a triage system for your digital assets.

Containment decisions aren't always obvious, and that's why you need them written down beforehand. Do you shut down affected systems entirely or keep them running to gather forensic information? This is the kind of question that should be decided by your incident response team in advance, not debated while the attack is actively happening.

Phase 3: Eradication

After you've stopped the active attack, you need to remove whatever malware, backdoors, or vulnerabilities the attacker exploited. This is where many companies make mistakes by jumping back online too quickly.

Your plan should specify that infected systems don't just get cleaned—they get rebuilding or reimaged. They get upgraded patches applied. They get thoroughly tested before they return to normal operation. For many businesses, this phase might mean working with external security consultants if you don't have specialized expertise internally. Budget-wise, this phase typically costs 15,000 to 35,000 DKK depending on complexity.

Phase 4: Recovery and Restoration

Now you're bringing systems back online, but carefully. You restore from clean backups. You validate that restored data is actually clean. You monitor closely for any signs that the attack wasn't fully eradicated.

This is also where you verify that your business processes are actually working again. It's not enough that servers are running—you need to confirm that customers can place orders, that employees can access their email, that critical workflows function normally.

Phase 5: Post-Incident Review and Improvement

After you've recovered, resist the urge to just move on. The most valuable security learning comes from examining what actually happened. Your incident response plan should schedule a formal post-incident review meeting within one to two weeks.

That meeting covers: What exactly happened? How did it happen? What did we do right? What could we have done better? What systems or processes need to be fixed to prevent this specific attack from working again? What early warning signs did we miss?

The answers to these questions become updates to your incident response plan cybersecurity process and improvements to your overall security posture. This is how your organization gets better at handling threats.

Building Your Incident Response Team

Your incident response plan needs a team, but you don't need a huge, dedicated team. For most Danish businesses, you're looking at between three and eight people with clearly defined roles.

The Incident Commander makes the critical decisions. This should usually be your IT director, security manager, or senior technical leader. They coordinate everyone else and decide when to escalate.

Technical specialists handle the actual forensic and remediation work. They know your systems inside and out. They understand where data flows and which devices matter most.

Communications lead handles notifying employees, customers, and authorities. This is often your HR lead or a designated PR contact. They manage the tone, timing, and content of all communications about the incident.

Senior management representative provides decision authority on business continuity questions. Should we keep systems down longer to be thorough, or restore them quickly to resume operations? Should we involve external consultants? These often have budget and strategic implications that need executive input.

The key is clarity. Everyone on your incident response team should know their role before an incident happens, not learn it during one.

Creating Communication Templates Before You Need Them

One of the most challenging parts of handling a security incident is figuring out what to say and to whom. Your incident response plan cybersecurity framework should include pre-written templates for different audiences.

Internal Communication Template

Your employees need to know what's happening, what they should do, and what's being done to protect them. A template might look like:

Subject: Security Incident Update – Action Required

We've detected unusual activity on our network that we're currently investigating. We've taken immediate steps to secure our systems and prevent any further impact. Here's what you need to know:

• Do not open any unexpected emails or click links from unknown senders
• If you notice anything unusual with your computer or login, notify IT immediately
• Change your password when IT directs you to do so
• We'll provide updates every [X hours/as they become available]

We're working around the clock to resolve this. Thank you for your patience.

Customer Communication Template

Transparency builds trust, but you also need to avoid panic. Keep it factual and action-oriented:

We're writing to inform you of a security incident affecting some of our systems. We've immediately launched an investigation and engaged security experts. Here's what you should do:

• Monitor your account for unusual activity
• Consider changing your password (here's how)
• Contact us if you notice anything suspicious
• We'll provide more details as our investigation progresses

Your security is our priority. We're committed to resolving this quickly.

Authority and Regulatory Communication

Depending on the type of data involved and its scope, you might need to notify authorities. Your legal counsel should review your templates, but they should be straightforward and factual. Include details about what data was affected, when you discovered it, and what you're doing about it.

The Practical Checklist: What Your Incident Response Plan Should Include

Here's what a working incident response plan cybersecurity document actually contains:

• Contact list with names, phone numbers, and email addresses for your response team and external resources (IT consultants, lawyers, authorities)

• Clear criteria for what constitutes different levels of incidents (minor vs. major vs. critical)

• Step-by-step procedures for each phase of response

• Inventory of critical systems and data you need to protect

• Backup and recovery procedures with documented recovery times

• Communication templates for different scenarios and audiences

• List of external resources you might need (forensics firms, PR consultants, legal counsel) with contact details and estimated costs

• Documentation and preservation procedures (logging what happened for both legal and learning purposes)

• Testing schedule (quarterly reviews, at minimum)

Testing and Updating Your Plan

A written plan that sits in a drawer and never gets tested is almost as bad as having no plan at all. You need to validate that your team can actually execute it when pressure is real.

Start with tabletop exercises quarterly. Gather your incident response team and run through a realistic scenario. Walk through decisions step by step. You'll quickly spot gaps—maybe someone's phone number is outdated, or the person you designated as incident commander has left the company, or your backup systems don't actually work the way everyone assumed they did.

Every time you update your incident response plan cybersecurity procedures—whether because you've discovered a gap or because you've changed your systems—communicate those changes to your team and test them. This is particularly important after any actual incident. The lessons you learned should immediately feed back into your procedures.

Budget roughly 4,000 to 8,000 DKK per year for professional tabletop exercises and plan updates if you work with external consultants, or handle them internally if you have the expertise.

Common Mistakes to Avoid

Having seen dozens of incident response plans across Danish companies, I can tell you what usually goes wrong.

Making the plan too complex. A 200-page document that nobody understands is worthless. Your plan should be clear, concise, and usable under stress. Aim for 10-20 pages, maximum. Complexity belongs in detailed procedures attached as appendices, not in the main document.

Assuming you don't need external help. Most organizations need outside specialists at some point during a serious incident. You need to know who you'd call, what they cost, and what their availability looks like. Having those relationships and contracts in place beforehand saves critical time. External security response can cost 20,000 to 50,000 DKK for initial assessment and containment, depending on scope.

Ignoring the legal side. Data breaches trigger requirements. In Denmark, you need to notify authorities in certain cases. Your incident response plan should include legal input, and your legal counsel should review your response procedures. Don't discover legal obligations during a crisis.

Forgetting about your backups. Your incident response plan is only as good as your ability to recover. If you can't restore systems from backup, you're not really contained or recovered—you're just dealing with the mess longer. Test your backups regularly and include backup recovery procedures in your incident response playbook.

Frequently Asked Questions

How long should it take to develop an incident response plan cybersecurity framework?

For a typical mid-sized Danish business, expect 4-8 weeks if you do it yourself with your IT staff, or 2-3 weeks if you work with an external consultant. The work includes inventorying critical systems, identifying team members, developing procedures, and creating templates. Most of the time goes into thinking through realistic scenarios, not writing documentation. Once you have a baseline plan, annual reviews typically take 1-2 weeks.

What's the difference between incident response planning and disaster recovery planning?

Incident response focuses on handling active security threats—detecting them, stopping them, investigating them, and recovering from them. Disaster recovery is broader and covers any significant disruption to your business, including natural disasters, hardware failures, or cyber attacks. Your incident response plan cybersecurity framework is a subset of your overall business continuity strategy. You should have both.

Do we need to involve external consultants in our incident response plan?

Not necessarily for planning, but having relationships in place with external specialists is smart. Many organizations use a hybrid approach: they handle the initial response and containment internally using their own expertise and procedures, but they have contracts with security forensics firms and other specialists ready to engage if needed. This balance between internal expertise and external resources works well for most companies.

How often should we test our incident response plan?

At minimum, quarterly. Run a tabletop exercise at least four times per year. After any significant change to your systems, infrastructure, or team, test your response procedures again to make sure they still work. Many organizations also run annual full-scale simulations where they actually simulate an attack in a controlled way and test their full response, though tabletop exercises are sufficient for most businesses.

What should we do with the incident response plan after we've written it?

Distribute it to your incident response team so everyone understands their role. Keep an updated physical copy accessible during emergencies—not just on your network, which might be compromised. Store it in a secure location that your team can access even if normal systems are down. Review and update it annually, and more often after actual incidents or significant organizational changes. Most importantly, actually use it. Treat it as a living document that guides your response, not a checkbox compliance exercise.

Conclusion

Building an incident response plan cybersecurity framework is one of those security investments that feels unnecessary right up until the moment you actually need it. Then suddenly, all those hours spent planning and all those details you documented become the difference between a bad day and a catastrophic one.

The good news is that you don't need to reinvent the wheel. You're not looking for perfection—you're looking for a clear, practical guide that your team understands and can execute when pressure is highest. Start with the five phases outlined above, identify your team, write down your procedures, create your communication templates, and then test everything.

Your incident response plan cybersecurity approach doesn't need to be complicated, but it does need to be real. It needs to reflect your actual systems, your actual team, and your actual capabilities. Make it specific to your business, make it clear enough that your team can follow it under stress, and treat it as something you'll actually use, not just something you check off.

The businesses that handle security incidents well aren't necessarily the ones with the biggest budgets or the most advanced technology. They're the ones that thought about what could go wrong, prepared for it, and trained their team to execute when it actually happens. You can do that too. Start today.
