Is Your Incident Response Plan Ready for the Spotlight?
This article is meant to be a checklist for your IR team to ensure that the tool will function as intended when it is used.
Introduction
In the ever-evolving world of cybersecurity, having an Incident Response Plan (IRP) is like having a fire extinguisher in your kitchen. You hope you never have to use it, but when a fire breaks out, you'll be incredibly grateful it's there.
However, just like a fire extinguisher, an IRP isn't a "set it and forget it" tool. With regulatory bodies increasing scrutiny and cyber threats becoming more sophisticated, a dusty, outdated IRP is as useful as a chocolate teapot. Many organizations have existing incident response programs, but given recent regulatory developments, these plans need to be expanded to increase the depth and scope of escalation, as well as to clarify roles, responsibilities, and communication channels.
The Critical Role of Incident Triage
When a security incident occurs, the first few moments are critical. It's the difference between a small, contained spark and a raging inferno. This is where incident triage comes in.
During the incident triage process, while an initial impact assessment is being performed, a quick checkpoint should be in place to determine which stakeholders should receive early notification of the incident. Think of it as the "should I shout 'FIRE!' yet?" moment. The key is to have a pre-defined process for this, so you're not making it up on the fly while the digital flames are licking at your servers.
When to Sound the Alarm: Escalation Criteria
Your organization must have clearly defined, documented escalation criteria that specify when an incident should be escalated after the triage stage is completed.
Of course, these criteria will vary from organization to organization. They will be based on several factors, like the incident's severity, relevant regulatory and compliance requirements, materiality, potential impact, and specific policies. For example, a data breach involving a certain number of customer records or a security incident with a particular risk rating might trigger an automatic escalation. Without these clear triggers, you risk either crying wolf for every minor issue or, worse, fiddling while your digital Rome burns.
Who Needs to Know?
Not every incident requires a full-blown, all-hands-on-deck response.
Your board of directors probably doesn't need to be woken up at 3 AM because a single employee clicked on a phishing link. Therefore, a clearly defined hierarchy of escalation levels should be developed, with each level representing a higher degree of severity.
For example, an organization might have three levels:
Level 1: Minor Incidents: Handled by the IT/security team with no immediate external reporting required.
Level 2: Moderate Incidents: Requiring involvement from legal and communications teams, with potential reporting to regulators.
Level 3: Major or Critical Incidents: Involving the executive leadership team (ELT), the board, and immediate notification to relevant authorities.
This tiered approach ensures that the right people are involved at the right time, without causing unnecessary panic or alert fatigue.
Roles and Responsibilities
Your incident response program should have clearly defined and documented roles and responsibilities for the individuals or teams involved in each incident escalation level.
This includes specifying who is responsible for coordinating the response, communicating with stakeholders, conducting investigations, and making decisions. Without this clarity, you'll have a chaotic situation where everyone is pointing fingers, and no one is taking charge. It's like a scene from a disaster movie, but with more spreadsheets and less dramatic music.
Incident Communication
Your IRP should also clearly define and document plans for internal and external communications, including communication channels, methods, and responsible parties for each escalation level.
The plan should include information on whom to notify and how to notify them, as well as any templates or scripts for incident reporting. This is not the time to be winging it. Having pre-approved communication templates can save you valuable time and prevent you from saying the wrong thing in the heat of the moment.
Reporting and Response Timeframes
In the world of incident response, the clock is always ticking. Regulatory bodies are imposing increasingly strict deadlines for reporting cybersecurity incidents.
For example, the EU's General Data Protection Regulation (GDPR) requires notification within 72 hours of becoming aware of a data breach [1]. In the US, the Health Insurance Portability and Accountability Act (HIPAA) requires notification without unreasonable delay and in no case later than 60 days following the discovery of a breach of unsecured protected health information [2].

Real-World Incident Response Failures
The headlines are filled with stories of companies that have suffered massive data breaches. While the technical details of these attacks are often complex, the incident response (or lack thereof) is often a key factor in the severity of the outcome. Let's look at a few examples:
The Change Healthcare Catastrophe
In February 2024, Change Healthcare, a subsidiary of UnitedHealth Group, was hit by a ransomware attack that crippled the US healthcare system [3]. The attackers, the BlackCat group, exfiltrated sensitive data and deployed ransomware, halting electronic payments and medical claims processing. The financial fallout was staggering, with UnitedHealth estimating the response cost at approximately $2.87 billion. To make matters worse, the company confirmed it paid a $22 million ransom. This incident exposed the massive vulnerabilities in the healthcare sector's cybersecurity and the devastating consequences of a poorly executed incident response.
The Snowflake Fiasco
In May 2024, the cloud data platform Snowflake experienced a significant data breach that affected over 100 of its customers, including major corporations like AT&T and Ticketmaster [3]. The attackers, associated with the Scattered Spider group, exploited the compromised credentials of a Snowflake employee account. The breach highlighted critical security lapses, particularly the absence of multi-factor authentication (MFA) and inadequate credential management among Snowflake's clientele. The attackers demanded ransoms ranging from $300,000 to $5 million from affected companies, underscoring the importance of a robust and well-rehearsed incident response plan.
The UK Ministry of Defence's Supply Chain Nightmare
Also in May 2024, the UK's Ministry of Defence (MoD) experienced a significant data breach when a contractor-operated payroll system was compromised [3]. The personal information of approximately 270,000 current and former UK military personnel was exposed. This incident highlighted the critical importance of robust cybersecurity measures, particularly in relation to third-party service providers. It's a stark reminder that your security is only as strong as your weakest link, and your IRP needs to account for your entire supply chain.
Don't Wait for the Smoke to Clear
Don't think that an effective Incident Response Plan is a luxury. Nor is it something your small organization cannot attain. With the right guidance and some effort, your team can also develop a robust plan that may make the difference between life and death for your organization when the time comes.
The cost of a data breach is not just financial; it also affects reputation. As the regulatory landscape becomes more stringent and cyber threats become more sophisticated, organizations can no longer afford to treat their IRP as a checkbox exercise. It's time to dust off that plan, put it to the test, and make sure it's ready for the spotlight. Because when a crisis hits, you don't want to be left holding a chocolate teapot.
Over and out.
