In the ever-intensifying digital landscape, organizations face a relentless barrage of threats. Ransomware is emerging as a particularly pervasive menace. In 2023, a staggering 73% of organizations paid a ransom to recover critical data. But amidst the backdrop of cyberattacks that loom ominously over businesses worldwide, the prevailing belief of invincibility paints a stark and sobering picture for IT leaders.
This is the “it couldn’t possibly happen to us” mindset coupled with antiquated incident response strategies.
Anticipate the future… or endure the aftermath.
Jeremy Nelson, Chief Information Security Officer, Insight North America, has seen this happen to organizations time and time again. “Underestimating the risk of being targeted is akin to leaving castle gates unguarded, enabling even a single knowledgeable individual to breach defenses and wreak havoc,” says Nelson.

The absence of a well-crafted incident response plan can exacerbate the detrimental consequences when an attack occurs. Unprepared organizations often encounter financial instability, operational disarray, reputational harm, emotional strain, and erosion of customer trust.
The gravest error lies in assuming immunity to cyberthreats and disregarding the lasting repercussions. That’s why business leaders tasked with safeguarding company assets must have a comprehensive — and current — incident response plan.
Cybersecurity is a multifaceted issue that demands strategic focus and investment — and a thoughtful incident response plan is a critical (though often neglected) component. Proper planning can mean the difference between a minor service disruption and a catastrophically disabling event. So, here’s everything you need to know to help safeguard your business from potential devastation.
Underestimating the risk of being targeted is akin to leaving castle gates unguarded, enabling even a single knowledgeable individual to breach defenses and wreak havoc.
A comprehensive incident response plan is comprised of several key components, each addressing different stages of a potential breach. Foundationally, this involves preparation; detection and analysis; containment, eradication, and recovery; and post-incident activities.
Each of these elements synergize to form a cohesive framework, enabling you to proactively handle potential threats and enhance your organization’s overall security posture.
Preparation
Establish a solid foundation by defining and documenting essential policies, roles, responsibilities, and procedures critical for a robust response to potential threats. This includes identifying vital assets, conducting comprehensive risk assessments, and assembling a proficient incident response team to implement effective offensive and defensive strategies.
Already have this complete? Excellent. Set deadlines to have it routinely reviewed and updated. Irregular updates might be necessary after events such as a merger or acquisition, employee turnover, major technology changes, or other team shifts.
Detection and analysis
In addition to meticulous preparation, security teams should assess their methods for detecting and analyzing potential security incidents. This involves setting up monitoring systems, establishing incident classification criteria, and creating protocols for collecting and analyzing data to determine the severity of attacks.
Containment, eradication, and recovery
Upon detecting a threat, the response plan should delineate precise steps for containment. This helps prevent further harm, address the root cause, and restore affected systems and data. These measures are crucial for minimizing the impact on business operations and swiftly restoring functionality.
In addition to limiting the breach, this piece of your incident response plan quiets the chaos following an incident. Teammates and partners are empowered to act swiftly and confidently during a stressful scenario.
Post-incident activities
Following the successful containment of a cyberthreat, essential post-incident activities should start immediately. Tasks should include a thorough review to comprehend the events, reasons behind them, and management of the response. This entails documenting key takeaways, updating the incident response plan, and implementing enhancements to bolster future response capabilities.
By thoroughly addressing each of these areas, your teams can respond to incidents more effectively. You can also limit potential damage and accelerate recovery measures for your organization.
Developing the initial framework for an incident response plan is only the beginning; ensuring its efficacy requires ongoing practice and evaluation.
Enter tabletop exercises — a dynamic and engaging method to put your plan through its paces (a step that organizations often overlook). Picture key personnel gathering to immerse themselves in hypothetical scenarios, where roles and responses are brought to life. As they tackle simulated challenges in a controlled setting, vulnerabilities are exposed, roles are clearly defined, and team collaboration reaches peak performance.
Practicing the incident response plan is the most often overlooked step in the process, and yet Nelson can’t emphasis enough its value and importance for success.
“You have to practice,” Nelson insists. “If you’re not going through and developing that muscle memory and bringing the people together that are actually going to be responsible for executing that plan at the time of crisis, when you’re not in crisis, it’s going to be exponentially worse when you are in the middle of watching all of your IT systems melt down, and you’re thinking about the longevity and survivability of your company.”
If you can take it up a notch, full-scale simulations and drills provide a hands-on method for testing the plan. Unlike tabletop exercises, these sessions often involve real-time scenarios that require participants to respond as they would during an actual incident. From phishing simulations to comprehensive mock attacks, these drills aim to assess the plan’s efficacy under pressure and guarantee the swift execution of essential actions by the incident response team. They also aid in evaluating detection and communication shortcomings, offering valuable insights for ongoing enhancement.

Another effective method for evaluating preparedness is through Business Continuity/Disaster Recovery (BC/DR) tests, a practice endorsed by Insight’s team of security experts to actively hone the restoration process. These tests familiarize individuals with new roles and leadership positions, fostering the development of diverse skill sets within the team.
Finally, regular reviews and updates are vital to keep incident response plans relevant and effective in the face of evolving cyberthreats. Given the persistent and innovative nature of attacks, countermeasures that were previously effective may no longer suffice in the present environment.
By incorporating insights from recent incidents, threat trends, and technological advancements, you can ensure the plan is up-to-date and responsive to emerging risks.
In terms of timing, Nelson advises updating an incident response plan at least twice a year.
This will enable you to adapt processes, personnel, and policies to mitigate potential threats effectively. Coupled with regular practice sessions, this approach ensures that your team remains adaptable and well-prepared to handle any challenges that may arise.
Developing a robust incident response plan is not only a technical decision but also a crucial business strategy. The financial repercussions of a data breach can be significant, encompassing expenses such as legal fees, regulatory fines, customer compensation, and revenue loss. Furthermore, the harm to a company’s reputation can have enduring consequences — eroding customer trust and potentially resulting in a decline in business.
As skepticism persists, IT leaders must ramp up cybersecurity efforts to tackle the rising concerns around privacy and compliance.
Still, convincing certain stakeholders and IT decision-makers to prioritize investment in incident response planning can be challenging. Especially with competing initiatives like multicloud adoption, AI, and infrastructure enhancements vying for attention and resources. Yet, the argument for investment gains greater traction when viewed through the lens of a business imperative rather than a mere technical necessity. A shift in perspective is crucial in an environment where cyberattacks are not a matter of “if” but “when.”
Nelson sheds light on the common struggle organizations face in prioritizing long-term planning, noting that those untouched by the direct impact of security incidents may find it arduous to justify preemptive strategies: “When a CISO has firsthand experience with a security incident, they understand the risks and drive proactive investments, unlike those who haven’t faced such challenges and struggle to prioritize incident response.”
Conversely, organizations that have weathered the storm of security breaches are more inclined to grasp the critical significance of preparedness. They will be more open to committing resources to incident response planning.
As attacks become more sophisticated, it’s clear that investing in both offensive and defensive measures is crucial for ensuring a comprehensive, robust approach to safeguarding your organization’s most valuable assets.
