Mastering the Art of Incident Response: From Chaos to Control

Today it is no longer about If Your organization will be exposed to a cyberattack, but WhenImagine this: an employee’s PC suddenly starts behaving strangely, displaying a threatening message that files have been encrypted and data has been exfiltrated. This is every IT professional’s nightmare – a ransomware attack unfolding in real time.

Your response in the first hours, days and weeks can make the difference between a minor hiccup and a catastrophic collapse. Drawing on the extensive experience of Nuspire’s cybersecurity experts Mike Pedrick, VP of Cybersecurity Consulting, and Chris Roberts, Chief Strategy Executive & Evangelist, we guide you through the critical phases of incident response, from the initial chaos to long-term recovery.

The first 72 hours: A race against time
When ransomware strikes, the incident response team must work tirelessly for the first 12 to 24 hours to keep the company afloat while reconstructing what happened. After 72 hours, regulatory and fiduciary obligations come into play. Many states’ breach notification laws require that interested parties be notified within this time frame.

“There is blood in the water… someone is ready to file a class action lawsuit against your organization,” warns Mike. “Trying to cover up or downplay the incident will only make the situation worse.”

The key is having a clear, documented process to validate the incident, contain it, eliminate the source, and proceed with recovery. But you can’t stop the bleeding if you don’t know where the damage is. Understanding your environment and assets is critical to quickly identifying affected systems and prioritizing containment efforts.

Beyond the initial reaction: Mastering the consequences
Once the immediate threat is contained, the real work begins. One of the first challenges is to determine the root cause. How did the attackers gain access? What was the initial point of attack?

“Unfortunately, in a great many cases, you won’t find the root cause,” Chris explains. “This frustrates more people than it should, especially senior management.” While it’s important to investigate, companies must balance the time to analyze with the need to eliminate and recover from the threat.

Recovery: It is a personal matter
There is no one size fits all solution for recovery. A manufacturing company that relies on just-in-time delivery has a much smaller window of tolerable downtime than other industries.

“Recovery means something different to everyone,” Chris explains. “This is where we move away from the technology standpoint and focus on communication, collaboration, cooperation and coordination with the business.”

Mike emphasizes the importance of aligning IT recovery capabilities with the organization’s risk tolerance and business continuity requirements.

“If the company says they can’t be down for more than four hours, but you know it will take 24 hours to restore service, you’ve got a date with destiny in the fifth hour,” Mike warns. “Torches and pitchforks will be fetched down the hall.”

Lessons Learned: Your Future Lifeline
One of the most overlooked aspects of incident response is conducting a thorough autopsy.

“Unless you’re sitting in front of two screens working on technical things and have a note document open on one screen, taking screenshots and documenting, you’re not going to remember what happened two, four or 24 hours later,” Chris points out.

This documentation is critical not only for internal improvements, but also for answering questions from regulators, law enforcement and insurance providers. It allows you to identify gaps in your response capabilities and should feed into a rapid test and improvement cycle.

Get external help: Together we are strong
Even large, established organizations turn to outside experts to review their plans and provide emergency support in the event of a major incident.

“My preferred external providers are those who will help you progress,” says Mike. “It should be a mentoring relationship to some extent.”

Chris agrees, pointing out that outside experts offer expertise and guaranteed response times. But it’s not a “set it and forget it” arrangement – you need to invest in the relationship and make sure everyone understands roles and responsibilities.

Strengthen your defense before the next attack
The principles presented here can help organizations bring order to the chaos of a cyberattack and emerge stronger. But the time to build that cyber resilience is now, before the next incident occurs. Waiting until you’re in the middle of a crisis to figure out how to respond is a recipe for disaster.

Here is Nuspires Incident Response On-call Service comes in. Our cybersecurity experts develop customized simulations that reflect your unique risks and lead your team through dynamic, interactive simulations. These aren’t just annual checkbox activities, but important rehearsals that ensure everyone knows their role when chaos ensues.
