Why Incident Response Planning is Critical for Cybersecurity Resilience

Cyber threats are inevitable, making preparedness necessary. In 2023, the average cost of a data breach reached $4.45 million. Implementing an incident response plan is vital for minimizing damage, ensuring rapid recovery, and maintaining customer trust and competitive advantage.

When it comes to cybersecurity, it’s not a question of if something will go wrong, but when. Online threats are becoming sophisticated, reminding us to be prepared at all times.

To grasp the growth of threats and how seriously companies take them, you can take a look at some numbers. For instance, global spending on cybersecurity is larger now than it was in 2021. Only last year, companies spent around $80 billion on cybersecurity, and there is a suggestion the number might reach 87 billion US dollars in 2024. 

One way to keep yourself safe is by using incident response planning. Think of it as a digital fire drill: it ensures that once the alarm goes off, everyone knows their role and how to handle the chaos.

Beyond the obvious, why is incident response planning so important for cybersecurity resilience? Let’s take a look.

The calm before the storm 

Imagine your company as a ship sailing smoothly through calm seas. The sun is shining, the crew is at ease, and everything appears perfect. Suddenly, without warning, dark clouds gather, the wind picks up, and a storm looms on the horizon.

In this scenario, would you prefer your crew to scramble in panic, or would you rather have them know exactly what to do because they’ve practised for this situation? The latter is the essence of incident response planning.

Cyber threats are like the storms on the horizon, and without a well-thought-out plan, you’re essentially leaving your company at the mercy of the waves. An incident response plan is designed to minimize damage and ensure that, no matter how severe the situation, your ship keeps sailing.

The anatomy of an incident response plan

Have you ever wondered what exactly goes into an incident response plan? It’s not just a document collecting dust in a company’s cloud storage with the label ‘Open in case of emergency.’ An effective plan is a living, breathing entity that evolves alongside your organization and the threats it faces. Here are the key components:

Preparation 

Preparation is the key. This is where you can assess your current security posture, identify potential threats, and define roles and responsibilities. You can use AI for better performance. For instance, SEON has a fraud prevention platform that uses AI-driven insight to stop fraud before it happens. 

This stage also includes training your team, which we will discuss later in greater detail.

Identification 

In the event of an incident, the first step is recognizing that something is not quite right. This involves monitoring systems for unusual activity and having protocols in place to determine whether it’s just a minor issue or something more serious.

Containment 

Once you have a thief in your grasp, you’ll want to secure him safely in prison. If you can’t catch him right away, you can still prevent further damage by isolating him in a single room, thus protecting the rest of the compound.

Containment strategies can be immediate or long-term, depending on the severity of the incident.

Eradication

After containing the incident, the next step would be to eliminate the threat. This could mean removing malware, shutting down compromised systems, or even revoking access for certain users. 

The goal is to make sure the threat is completely neutralized. 

Recovery

When the threat has been eliminated, the focus shifts to getting everything back to normal. This may involve restoring data from backups, patching vulnerabilities, or rebuilding systems. Utilizing some of the best compliance audit software can help achieve this by meeting regulatory requirements, assessing risks, and securely storing the necessary evidence for potential audits. The key is to ensure everything is secure before resuming normal operations.

Lessons learned 

Perhaps the most important part of the plan is what happens after the dust settles. A thorough review of the incident can provide valuable insights into what went wrong and how to prevent it from happening again. This is where the plan evolves and improves over time.

The cost of not being prepared 

The numbers don’t lie—companies caught off guard by cyber incidents often face serious consequences. According to a 2023 report by IBM, the average cost of a data breach worldwide is 4.45 million US dollars. And that’s just the financial impact. Companies also have to deal with the loss of customer trust, damage to their reputation, and potential legal ramifications. Now, compare that to the cost of implementing an incident response plan. It’s like choosing between paying a small insurance premium or risking everything in a disaster.

For instance, when Sony Pictures was hit by a massive cyberattack in 2014, the damage was extensive. Sensitive data was leaked, including unreleased films, employee information, and confidential emails. Although Sony Pictures had some security measures in place, they lacked a proper incident response plan. For years, this case has been a topic of numerous cybersecurity studies, highlighting the importance of having a comprehensive incident response strategy.

As for the Maersk ransomware attack in 2017, that was a big mess. The NotPetya virus crippled the entire company, causing an estimated 300 million dollars in damages. The attackers demanded 300 Bitcoins for the decryption key, but it turned out that there was no key available. Maersk wasn’t the only victim; the global impact of the NotPetya attack was so severe that it was likened to “using a nuclear bomb to achieve a small tactical victory.”

Maersk, a shipping giant with operations in over 70 ports worldwide, managed to recover from the NotPetya ransomware attack, but it was largely due to sheer luck. At the time of the attack, their facility in Ghana was experiencing a blackout, which prevented the virus from infecting their systems there.

Fortunately, backup data was found at this facility. This data was then transferred onto a disk, which had to be physically retrieved—a process that involved a complicated logistical operation, including obtaining visas and arranging flights. Although Maersk didn’t have a proper incident response plan before the attack, they certainly implemented one afterwards.

The human element

Have you ever heard the saying, “Fire is a great servant but a bad master”? The same can be said for technology. Its strength depends on the people using it. Even the most advanced cybersecurity tools can be rendered useless if the human element is overlooked.

This is why training and awareness are crucial parts of incident response planning. Your team needs to be aware of the latest threats and know how to respond effectively.

This isn’t just about technical training for your IT staff. Everyone in the organization should understand basic cybersecurity practices and their role in responding to potential incidents. By organizing drills and simulations, you can ensure that their responses are quicker and more confident in the face of threats.

Automaton and AI 

You’ve likely heard a lot about artificial intelligence (AI) and its numerous benefits. In cybersecurity, AI-driven tools can be particularly helpful by analyzing vast amounts of data to identify patterns that might indicate a cyber threat. Automation can then take immediate containment actions, such as isolating affected systems or blocking malicious traffic, to prevent further damage.

Incident response as a competitive advantage 

Cybersecurity resilience isn’t just about protecting your assets—it’s also a competitive advantage. If you and your company can demonstrate a strong incident response, you’re more likely to earn the trust of your customers, partners, and stakeholders.

In the aftermath of a cyber incident, the speed and efficiency of your response can significantly impact your company’s reputation. A well-handled incident can actually enhance your reputation, showing that you can manage crises effectively and maintain trust even in challenging situations.

Keep the plan fresh 

Regular reviews, testing, and updates ensure that your incident response plan remains effective and relevant in the face of new threats. One way to keep your plan up-to-date is by conducting regular tabletop exercises. These simulated incidents allow your team to practice their responses in a controlled environment, without the risk of panic.

Additionally, staying informed about the latest cyber threats and trends is crucial for refreshing your incident response plan. You can organize seminars or send your employees to attend them to gain the latest insights. Subscribing to a cybersecurity newsletter is also beneficial, as it will keep you updated with emails about any changes or emerging threats in the field.

The bottom line

Incident response planning in cybersecurity is like a safety net—it’s there to catch you when things go wrong. Having proper security measures, like guards, firewalls, and advanced technologies, is important, but it’s equally crucial to have a plan for when a security breach occurs. Incident response planning serves as a vital plan B, complementing your primary defences. As one martial artist wisely put it: “To win the battle, it doesn’t matter how hard you strike, but how fast you recover from your opponent’s strike.”

The same principle applies to cybersecurity threats. When a breach happens (and it inevitably will), the key is how quickly and effectively you can recover. That’s where an incident response plan becomes essential. By preparing, training, and continuously improving your response strategies, you can transform potential threats into manageable challenges. This ensures that your company remains resilient and your operations steady, no matter what threats come your way.
