Cybersecurity Incident Response Plan: How Your MSP Can Help

A cybersecurity incident occurs. What do you do? You know that every minute that passes after a cybersecurity incident is potentially thousands of dollars or thousands of records stolen. But if you don’t have a proper cybersecurity incident response plan, you may not know what the next step is. By the time you need a cybersecurity incident response plan, it’s already too late to formulate one. The time to make one is now.

Key Takeaways: 

• A cybersecurity incident response plan is a documented, pre-approved framework that defines how your organization detects, contains, eradicates and recovers from security incidents.
• The plan covers who is responsible at each stage, how decisions get escalated, what gets communicated to whom and how the organization learns and improves after each event.
• Without a plan, critical time is lost to improvisation while the incident continues to spread.
• An MSP can help develop, implement and continuously improve your incident response plan while providing the 24/7 monitoring and response capability to execute it.

What is a Cybersecurity Incident Response Plan?

A cybersecurity incident response plan is very similar to a disaster preparedness plan. Employees have to be trained to identify cybersecurity incidents; they then need to be empowered to act. They need to know what to do and who to contact. Everyone should know who has to be notified when a cybersecurity threat occurs, and how and when incidents should be escalated.

A solid cybersecurity incident response plan should include:

• Your team. This includes those who are empowered to act, but it also needs to educate employees on what they should do as well. Everyone should be aware of the incident response plan, so they can make better decisions in the moment.
• Detection. What actions should they take to detect and mitigate the threats? What tools should they use? What should be immediately protected and isolated? These are the first things that a cybersecurity team should do.
• Contain. A security incident can spread very quickly. Anything that should be protected immediately needs to be isolated so that the spread can be contained.
• Assess. Once the incident has been detected and contained, the team will need to assess the damage. How severe has the issue been? Some companies spend months trying to figure out how much damage has been caused through the use of forensics.
• Notify. If data has been breached, people need to be notified in a timely fashion. You may want to assess the severity of the event first, but you will need to notify them as soon as possible.
• Protect. Once the issue has been addressed, action should be taken to protect the system in the future, both from this event and other similar events.

And, of course, the process of repair will also need to begin. Having a comprehensive cybersecurity incident response plan means that this type of planning doesn’t need to be done on the fly.

Without a cybersecurity response plan, many employees don’t take actions when they identify threats. Important time can be lost as employees struggle to figure out what to do and who to contact, and it may not be immediately obvious who is responsible for addressing the issues.

Common Cybersecurity Incidents Your Plan Must Address

A cybersecurity incident response plan is only useful if it accounts for the threats your organization actually faces. The most common incident types in enterprise and mid-market environments include:

• Ransomware: Malware that encrypts systems or data and demands payment for decryption. Ransomware incidents often involve weeks of prior attacker access and may include data exfiltration before encryption occurs.
• Phishing: Social engineering attacks that trick users into revealing credentials or downloading malware. Phishing is the most common initial access vector in enterprise breaches.
• Insider threats: Misuse of access by employees, contractors or partners, whether intentional (e.g., data theft, sabotage) or accidental (e.g., misconfiguration, unintentional data exposure).
• Data breaches: Confirmed unauthorized access to or exfiltration of sensitive data. Breaches trigger regulatory notification obligations with specific deadlines that your plan must account for.
• DDoS attacks: Distributed denial-of-service attacks that flood systems to disrupt availability. Response focuses on mitigation and maintaining business continuity rather than forensic investigation.
• Credential theft: Attackers harvesting valid usernames and passwords through phishing, keyloggers or dark web purchases. Compromised credentials enable lateral movement and privilege escalation.
• Supply chain attacks: Compromise delivered through a trusted vendor, software update or third-party integration. These are particularly dangerous because they exploit trust relationships and may be difficult to detect.
• Cloud account compromise: Unauthorized access to cloud environments through stolen credentials or misconfigured permissions. Cloud incidents require a distinct response playbook due to the shared responsibility model and different forensic constraints.

Incident Response Lifecycle

The incident response lifecycle plan outlined below gives security teams a repeatable framework for moving from detection to recovery in a structured, defensible way. Each stage has a defined goal and a clear handoff to the next. 

Cybersecurity Incident Response Plan Example: The 6 Stages

The six-stage model formalized by the SANS Institute is the most widely adopted incident response framework in enterprise security programs. Your plan should map directly to these stages, defining what your team does at each one.

Stage 1: Preparation

Preparation is everything your organization does before an incident occurs. This is the stage your plan primarily lives in, e.g., documented roles and responsibilities, deployed tooling, communication protocols, escalation paths and tested playbooks. Preparation is also the stage most organizations underinvest in, which means it’s the one most responsible for how badly a breach plays out when it does happen.

Stage 2: Identification

Identification is the detection and confirmation of a security incident. The plan needs to define what constitutes a confirmed incident, who has authority to declare one, what documentation is required and what notification timelines are triggered at declaration. A confirmed incident declaration is a formal event, not just a ticket in the queue.

Stage 3: Containment

Containment stops the spread while preserving forensic evidence. Your plan should distinguish between short-term containment (i.e., isolating affected systems immediately) and long-term containment (i.e., establishing a stable defensive posture that allows business operations to continue during eradication). Critically, your playbooks need to address the tension between speed and evidence preservation, since acting too fast can destroy what you’ll need later.

Stage 4: Eradication

Eradication removes the root cause(s), e.g., malware, persistence mechanisms, compromised credentials and the initial entry point. Your plan should make clear that nothing comes back online until eradication is confirmed. Restoring systems before the environment is clean is one of the most common – and most expensive, since it can lead to follow-up incidents – mistakes in incident response.

Stage 5: Recovery

Recovery restores operations safely. The plan should define restoration priorities (customer-facing systems first), validation requirements before systems reconnect and who has sign-off authority. A system that boots is not the same as a system that’s safe to return to production.

Stage 6: Lessons Learned

“Lessons learned” is the stage most organizations skip. A structured post-incident review should produce specific, assigned action items, rather than vague commitments to, for instance, “improve detection.” The output of this stage feeds directly back into Preparation, closing the loop on the lifecycle. 

For organizations under CMMC, NIST 800-171 or similar frameworks, documenting lessons learned also serves as evidence of a functioning incident response program.

Who Should Be on an Incident Response Team?

We’ve previously mentioned “your team” as a component of the plan, but the composition of that team deserves more specificity. Incident response is not solely a security function; it spans everything from legal and communications to HR and executive leadership. Every person mentioned below should have a defined role in your plan before an incident occurs.

Role assignments should be documented by name and backup, not just by title. If your CISO is unreachable at 2 in the morning, your plan needs to specify who has authority to make containment decisions in their absence. Ambiguity about decision-making authority is one of the most common causes of delayed response.

How to Create a Cybersecurity Incident Response Plan

A cybersecurity incident response plan isn’t a single document; rather, it’s like a computer program. You’re putting together a path that will, ideally, address the needs in front of you when executed properly. However, much like a program, building one that holds up under pressure requires working through each of the following components deliberately.

Identify Critical Assets

You can’t protect what you haven’t mapped. Before writing a single response procedure, your organization needs a current inventory of the systems, data and processes that would cause the most damage if compromised. This includes customer data repositories, financial systems, operational technology, cloud environments and third-party integrations. Priority in your response playbooks should follow the criticality of the assets involved.

Define Roles and Responsibilities

Every stage of the response lifecycle needs a named owner. The plan should specify who declares an incident, who leads the technical investigation, who approves containment actions that take systems offline and who communicates externally. Overlapping responsibilities and unclear authority are common failure modes in live incidents, as one member of the team assumes their coworker has it covered – while the coworker is making that exact same assumption in reverse.

Establish Escalation Procedures

Not every security alert is an incident, and not every incident requires executive involvement. Your escalation procedures define the thresholds: what severity level triggers what response, who gets notified at each level and what decisions require senior authorization. Documented escalation paths compress response time by eliminating the uncertainty of who to call next.

Create Communication Plans

Your plan needs pre-defined communication channels and templates for internal stakeholders, legal counsel, your cyber insurer, regulators and – if any relevant data is breached – affected customers. One frequently overlooked element: establish an out-of-band communication channel before an incident. If your email system is compromised, you need a way to coordinate your response that doesn’t run through the infrastructure you’re trying to recover.

Build Response Playbooks

A plan tells your team what to do. Playbooks tell them how to do it for specific incident types. A ransomware playbook looks different from a phishing playbook, which looks different from a cloud account compromise playbook. Each should define the specific steps, tools and decision points relevant to that incident type, layered on top of the core six-stage framework.

Test and Update Regularly

A plan that’s never been tested is just a piece of paper. Tabletop exercises that walk your team through simulated scenarios expose gaps in the plan before a real incident does. Most frameworks recommend at least one tabletop per year; organizations under active compliance obligations like CMMC or HIPAA should run them at least twice annually. The plan should also be updated after every real incident where it was invoked, and after any major infrastructure change.

How MSPs Support Incident Response

Cyber incident response is complex, and it requires that a company be able to trust its employees to act swiftly and correctly. An MSP can help. An MSP provides a number of services, including:

• Creating an incident response plan for your organization. As your MSP will be managing your security, they will be a critical part of your response plan.
• Providing your employees with incident response training. Employees can be trained when onboarded and at intervals regarding what they should do when threats are found.
• Monitoring the system 24/7. The incident response team cannot act if the incident is never uncovered. An MSP improves the chances that an incident will be identified quickly.
• Mitigating the threats. MSPs are skilled at mitigating threats quickly, and therefore saving an organization a tremendous amount of time.
• Proactively preventing threats. An MSP that is familiar with your network setup will be able to suggest changes and good practices accordingly, thereby proactively mitigating any potential threats.
• Managed Detection and Response (MDR). An MSP with MDR capabilities provides the tooling and analyst coverage to detect threats faster than most internal teams can manage, reducing the dwell time that determines how much damage an attacker can cause before containment begins.
• Incident containment support. When an incident is confirmed, an MSP can execute containment actions immediately, isolating affected systems, revoking compromised credentials and blocking attacker infrastructure – rather than waiting for internal teams to convene.
• Recovery support. MSPs with incident response experience can assist with validated restoration, helping ensure that systems return to production clean and that the organization doesn’t repeat the most common recovery mistake: restoring from backups before the environment is confirmed clear.
• Security assessments. Regular vulnerability assessments, penetration testing and tabletop exercises conducted by your MSP keep the incident response plan current and expose gaps before attackers find them.

Your MSP can help you not only create a cybersecurity incident response plan, but also can help you follow it. Moreover, your MSP can reduce the chances that you’re going to experience a major cyber security event.
