How To Build A Strong Cybersecurity Incident Plan For Your Firm

Cyber threats pose a serious risk that all businesses must contend with. As an organization’s leader, you have a duty to implement robust protections that reduce your firm’s vulnerability to cyberattacks.

A key part of any cybersecurity strategy is developing an effective incident response plan. This comprehensive plan will enable your company to respond quickly and minimize impacts if a security breach does occur.

Given the potential harm cyber incidents can inflict, it is not a matter of if you will need to use your response plan but when. Investing the time now to create a detailed plan will pay dividends through enhanced readiness when you face a real-world attack. Follow these essential steps to build a resilient incident response plan tailored to your firm’s needs.

Assemble Your Cybersecurity Incident Response Team

Cybersecurity Incident Response Team

Establishing a prepared and empowered cybersecurity incident response team is a critical first step. You need the right experts involved to assess threats, manage the response, and minimize potential impacts. At a minimum, the team should include representatives from:

  • Information Technology: Your IT team has in-depth knowledge of your technical infrastructure, systems, and security capabilities. Their role is to manage the monitoring, detection, analysis, and remediation of any compromise or attack on your networks and data. Designate your Chief Information Security Officer, and other key IT leaders focused on ICT services.
  • Legal: In-house legal counsel or an external legal partner is essential to provide guidance on compliance issues and liabilities associated with a cyber incident. They can advise on proper evidence gathering, notifications, and actions to take during investigations or lawsuits. Select seasoned lawyers with data privacy and cybersecurity expertise.
  • Communications: Your public relations specialists should lead efforts around internal and external communications before, during, and after an incident. They will help craft messaging, liaise with media outlets, and control the public narrative regarding the event and your response. Pick communicators experienced in crisis scenarios.
  • Human Resources: HR partners understand your workforce considerations and policies. They can assist with employee notifications and actions, investigate insider threats, and manage any fallout or anxieties among personnel. Identify HR leaders with strong interpersonal engagement skills.
  • Business Operations: Leaders of core business units and functions bring key insights on potential operational impacts, continuity risks, and recovery priorities. They can help assess and manage disruptions to time-sensitive operations. Engage ops/production specialists, which is integral to daily workflows.

IT security experts like your Chief Information Security Officer, forensic investigators, security engineers, and technical project managers should join these stakeholders. You may also appoint an Incident Commander to lead the team’s overall strategic direction.

Define roles like Communications Lead, Legal Counsel, Technical Lead, and Operations Lead. Document each member’s distinct responsibilities during incident planning and response. Empower them to make security decisions within their domain. With the right team in place, you’ll have the diverse expertise to address any type of cyber incident your organization may face.

Establish Incident Classification Levels

A strong incident response plan will define a scale for categorizing the severity of cybersecurity events. This provides your team with consistent criteria for evaluating threats and determining the appropriate response. Many organizations use a three-tiered scale:

  • Low – Isolated, routine incident with minimal impact
  • Moderate – Malicious activity with potential operational disruption
  • High – Widespread attack on critical systems or data

You may expand on the above by assigning specific characteristics or examples to each tier. The severity level of an incident will dictate the scale and urgency of your response efforts. Define escalation protocols linked to each classification to formalize incident reporting, alert procedures, and resource engagement based on severity.

Develop Detailed Incident Response Playbooks

At the core of your cybersecurity response plan are the playbooks that outline sequential response procedures. Your team should have access to detailed playbooks that map response activities specific to incidents classified at each severity tier.

Solid playbooks will provide established workflows for:

  • Detecting and reporting incidents through proper channels
  • Escalating the incident to activate your response team
  • Investigating threat characteristics and impacted areas
  • Containing the incident to prevent additional exposure or harm
  • Analyzing root causes and vulnerabilities enabling the incident
  • Recovering compromised systems and data to normal operations
  • Preserving evidence and indicators of compromise
  • Notifying leadership and external stakeholders per protocol
  • Documenting the incident response and learnings

With rigorous procedures governing each phase, your team can follow the prescribed playbooks aligned to the incident severity detected. This enables consistent and compliant response execution.

Formalize Your External Partnerships

An integral component of response planning is establishing trusted relationships with third-party partners qualified to supplement your incident response capabilities. These may include specialized cybersecurity firms, forensic investigators, communications consultants, legal counsel, cyber insurers, and law enforcement.

Research and maintain formal agreements with proven vendors that provide emergency response services relevant to your organization. Defining these partnerships in advance will accelerate access to expertise when facing a real-world incident.

Your playbooks should outline when and how to engage each partner depending on the severity tier. Providing pre-authorization and response integration procedures will help you tap into external capabilities faster.

Communicate Effectively Throughout The Response

Cybersecurity incidents present complex communications challenges. Your plan should establish policies and procedures for communicating with stakeholders during and after a cyber event.

Internally, instruct employees on proper reporting procedures for suspicious activity. Emphasize the importance of quick notification through approved channels. Outline standards for ongoing internal communications to keep personnel informed on response progress and required actions.

For external communications, designate specific team members authorized to issue statements and interface with customers, media, law enforcement, and other entities. Define the review and approval process for any materials released. Timely and accurate communications will enable you to control the narrative and demonstrate your response efforts.

Conduct Ongoing Training To Test And Validate The Plan

An effective cybersecurity incident response plan requires consistent maintenance and validation. Schedule regular simulated exercises to test your plan and response capabilities. Use post-exercise debriefs to identify gaps and areas for improvement. Revise the plan based on lessons learned.

Review and update key elements of the plan periodically. Refresh contact information for internal/external partners. Incorporate relevant changes in technologies, business operations, regulations, or threats into your procedures. Keeping your plan current and battle-tested will reinforce preparedness over time.


Constructing a robust cybersecurity incident response plan is a foundational investment every firm must undertake. Defining response team roles, severity classifications, playbooks, communications protocols, and more will enable your organization to navigate crises with confidence.

While cyberattacks cannot be fully prevented, proper planning and preparedness will empower your business to effectively manage incidents and mitigate damages. Don’t leave your firm’s response readiness to chance – make building a strong cybersecurity incident plan a top priority today.
