Cyber Resilience in Action: Advanced Incident Response Strategies

Published On: March 26, 2024Categories: Blog, Uncategorized

Welcome to the second part of our blog series, “Cyber Resilience in Action: A Two-Part Guide to Transforming Data Breach Response.” Having explored the strategic role of AI and automation in reducing data breach costs in Part 1, “Empowering Defenses: The Role of AI and Automation in Reducing Data Breach Costs,” we now shift our focus to advanced incident response strategies. Today’s post explores the six essential steps of incident response planning, providing a blueprint to enhance your organization’s cyber resilience in the face of ever-evolving threats.

Why Incident Response Can’t Wait

The escalating complexity and frequency of data breaches underscore the critical need for a comprehensive incident response (IR) plan. With IBM’s 2023 Cost of Data Breach Report highlighting a steep rise in breach costs to USD 4.95 million for incidents lasting over 200 days, it’s clear: time is money, and every second counts in mitigating the fallout. Each day a breach goes uncontained not only inflates the financial toll but also compounds the operational and reputational damage.

Mitigation is the goal, but it’s not always achievable. When breaches occur, the focus shifts to rapid containment, eradication, and recovery, facilitated by a well-structured incident response plan. But it’s not just about the financial repercussions. The SEC’s new Cybersecurity Disclosure Rule adds another layer, requiring publicly traded companies to disclose material cybersecurity breaches within a tight four-day window.

Here’s the kicker: IBM’s report reveals a potential cost saving of USD 1.49 million for organizations with well-honed incident response strategies.

Incident Response: The Strategic Linchpin

A robust incident response plan is more than a procedural document; it’s a strategic blueprint that enables organizations to transition from reactive to proactive postures, effectively managing the aftermath of security breaches to limit damage, reduce recovery time, and cut costs. Effective IR planning is about foresight and preparation. It’s about having a playbook ready, so your team isn’t left scrambling when a breach occurs. This approach is not just about minimizing damage but also about ensuring business continuity and compliance.

Notably, IBM’s 2023 Data Breach report highlights a growing trend: 51% of organizations plan to increase their security spending, focusing significantly on enhancing their IR capabilities. This strategic shift underscores the recognition of IR’s critical role in today’s cybersecurity landscape.

Building an Effective Incident Response Plan

Developing and implementing a robust IR plan involves several key steps, from understanding the incident response lifecycle to defining communication strategies and ensuring legal and regulatory compliance. Each stage, from preparation to post-incident review, is designed to not only address current threats but also to bolster your organization’s defenses against future challenges.

An effective IR plan is tailored to specific threat scenarios, outlining detailed actions for containment, eradication, and recovery. It’s designed to address distinct threats with tailored strategies, ensuring a rapid and coordinated response. For example, consider supply chain attacks, a prevalent scenario where attackers target an organization’s systems through third-party vendors. Despite a staggering 2,600% increase in such attacks since 2018, the IBM report reveals that only 32% of organizations have specific IR plans for such attacks. Proactive planning for these and other scenarios is crucial, significantly mitigating their potential impact and safeguarding your organization’s systems and data.

6 Critical Steps for Effective Incident Response Planning

How you develop and enact specific response plans will vary based on your industry and organization, but there are six steps to help you get started.

  1. Understand the Incident Response Lifecycle

What is the overall lifecycle of incident response planning in cyber security? Let’s take a look at how the NIST incident response framework breaks down the incident response cycle:

  • Preparation: Define your IR team and assign clear roles and responsibilities. This foundation sets the stage for a coordinated and rapid response to threats when every second counts.
  • Detection and Analysis: Equip your team with the tools and processes to quickly identify when a breach occurs. Early detection is critical to minimizing impact.
  • Containment: Rapidly isolate and contain the threat to prevent further damage. Effective containment strategies are crucial to limiting the scope of a breach.
  • Eradication: Once contained, eliminate the threat from your environment, ensuring that the attacker’s presence is completely removed.
  • Recovery: Methodically restore affected systems and data, returning to normal operations while maintaining vigilance for any signs of lingering issues.
  • Communication: Establish clear communication protocols to ensure seamless coordination among team members and stakeholders during and after an incident.
  • Legal and Regulatory Compliance: Understand and adhere to legal requirements and compliance mandates to mitigate additional risks and penalties.
  • Post-Incident Review: Analyze the incident and your team’s response to it. Identify what worked, what didn’t, and how you can strengthen your defenses for the future.
  1. Identify and Prioritize IT Assets

Risk assessments begin by identifying and prioritizing all IT assets, then usually dive deeper into vulnerabilities and mitigation controls. Developing response plans should begin with the same process — understanding the highest protected assets is valuable for any scenario.

Data discovery and classification are foundational elements of this step in the process, so you know where everything is stored. Then, this information can be used to inform how individual response plans are developed to protect the most sensitive data. Similarly, understanding which systems and infrastructure components are necessary for the business to operate will greatly inform response plans.

  1. Define Communication Strategies

Incidents usually involve compromising IT systems, which means your usual communication platforms may no longer be secure or even available. How will your teams communicate?

While incident response plans are scenario-based, defining an overall communication strategy that’s more broadly applicable is highly valuable. Making sure management and teams all understand how they should communicate while addressing an incident goes far in rapid recovery times.

  1. Create Robust Strategies for Handling an Active Crisis

Earlier, we touched on NIST’s containment, eradication, and recovery stages for incident response planning. This general workflow should form the foundation of response strategies, focusing on specific steps based on the scenario.

These three incident response steps can be defined as:

  • Containment: Identifying the extent of the damage and taking steps to keep the threat contained is the first step of any response plan. Generally, the goal is to make sure sensitive data and critical systems remain protected.
  • Eradication: Usually, incident responses take place while the threat is still active and causing damage. Identifying and stopping the source of the incident is a central and often lengthy component of a response plan and often the main focus.
  • Recovery: Once eradicated, the extent of the damage needs to be evaluated so steps can be taken to recover. For example, recovery might mean bringing communication tools back online or gathering evidence of the breach for further analysis.

The bulk of incident response planning covers the above three phases specific to a range of scenarios. Containment won’t always look the same, but it will almost always be an important first step.

  1. Include Legal and Regulatory Compliance

There are legal and compliance aspects of many types of incidents that must be considered. One study found that many organizations have indicated that multiple aspects of the law are still challenging, including:

  • Knowing when to contact legal counsel (47%)
  • Lacking right-to-audit clauses (47%)
  • Teams not prepared to preserve evidence (46%)

Keeping these concerns in mind while creating incident response plans is critical to remaining fully compliant in the face of a cyber-attack or other disruptive incidents. Dictating when to contact legal teams will help navigate many other issues and provide robust training.

  1. Post-Incident Reviews and Refinement

Once an incident is resolved, post-incident reviews should take place soon after. Managers and teams should meet to discuss what went well and what could have gone better. The primary goal of the review phase is to find opportunities for valuable corrective action.

Corrective actions may focus more on how the response plan could have been better but often also include identifying if teams need additional training in some areas. Post-incident reviews may also discover that entirely new tools or processes need to be adopted to become more resilient.

Testing and Practicing the Incident Response Plan

Practicing your IR plan is as crucial as creating it. Teams should practice incident response plans before they’re used in a live incident. While this step is certainly part of building an effective plan, it’s worth discussing on its own — it’s a never-ending process.

The first draft of an incident response plan will likely have some issues that aren’t discovered until it’s put to work. Testing and practicing these plans in a contained or simulated environment help identify these problems and uncover ways to improve them. Regular drills and simulations will expose weaknesses, allowing for timely refinement. This proactive testing ensures your team is ready to execute the plan efficiently under real-world conditions.
