How to respond to a cyber threat – a step-by-step guide

Introduction

Setting the scene…

You’re working through your day-to-day operations when suddenly, you get an alert: suspicious activity detected.

What do you do?

Having a cyber incident response plan is key to your business survival. When threats are identified and managed quickly, damage can be minimised.

When organisations don’t know what to do, the threats and the costs of resolving them skyrocket.

The first 24 hours are critical. Research shows that the faster an organisation detects and responds to a breach, the lower the damage. The difference between detecting a breach in hours versus days can be measured in thousands of pounds.

Step 1: Detect and alert

Early detection is absolutely key, helping to reduce impact and cost. Remaining vigilant using continuous monitoring systems, like CybaOps, keeps you ahead of the threat, allowing you to check for anomalies and alerting you to suspicious activity. If and when something untoward is detected, alerts go to your team immediately.

Step 2: Isolate and contain

Once alerted, your first action should be containment. If an infected system is identified, isolate it from your network to prevent the threat from spreading.

This doesn’t mean shutting everything down; it means taking precise and decisive action to separate the compromised asset from others while maintaining business continuity.

Step 3: Investigate and document

Keeping a clear record of the threat will help you to understand what happened, how the attack unfolded and what was accessed. Just the same as you would with a physical crime, document everything.

This information will prove crucial to your response, understanding your vulnerabilities, and potentially for legal or regulatory reporting.

Step 4: Remediate and eradicate

Remove the threat. This might mean patching vulnerabilities, resetting credentials, removing malware or rebuilding systems.

Whatever needs to be done, your goal is to eliminate the threat entirely so it can’t resurface.

Step 5: Communicate

Depending on the severity and what data was involved, you may need to notify affected parties. Clear communication helps maintain trust and meet legal obligations. Many compliance frameworks mandate breach notification within specific timeframes. Transparency builds trust, even in difficult situations.

Step 6: Review and improve

After the incident, conduct a post-mortem. What went wrong? What did you do well? Use these insights to strengthen your defences and prevent similar incidents in the future.

Build your response plan now

A thorough and well-executed response will help your business to minimise cyber threat disruption in the face of an attack.

It’s essential to act now to plan your cyber threat protocol; don’t wait for the worst to happen before you act.

In addition to a step-by-step guide, your plan should include the following:

• Key team members and their roles
• Escalation procedures
• Communication templates

Get your team on board and be prepared

Having a proactive and responsive team will help you significantly in the face of a cyberattack.

Make sure your staff:

• Understand your cyber threat response plan
• Know how to respond and report should they notice anything suspicious
• Know what they should or shouldn’t say to customers

Cyber incidents are a matter of “when,” not “if.” Organisations with solid response plans survive breaches with minimal damage. Those without them often face catastrophic consequences. Investment in detection, response capabilities and planning pays dividends when threats emerge.

“When it comes to cyberattacks, prevention is undoubtedly the best way to ensure your systems are safe – but breaches do happen. Even the most well-protected organisations are susceptible, which is why having a clear action plan to deal with attacks is key.

“Knowing your process and acting swiftly can be the difference between minimal disruption and total shutdown. It’s vital to create your plan, understand it and review it regularly to keep yourself a step ahead of cybercriminals.

“With a well-documented strategy and a well-informed team, you can keep your business protected.”
