The fifth action is to recover from the incident by restoring data and services, and verifying that systems are functioning properly.

The final action is to conduct a post-incident review to identify any lessons learned and make improvements to the incident response plan for future incidents.

Action 1: Preparation and Planning

The first action recommended by NIST is preparation and planning. This action involves developing an incident response plan that defines the roles, responsibilities, and procedures for responding to cybersecurity incidents. The incident response plan should include a detailed risk assessment, incident response team structure, communication plan, and a process for testing and updating the plan.

Furthermore, it is important to ensure that all employees are trained on the incident response plan and understand their roles and responsibilities in the event of a cybersecurity incident. Regular training and awareness programs can help to ensure that employees are equipped with the knowledge and skills necessary to respond effectively to incidents.

In addition, organizations should consider conducting tabletop exercises and simulations to test the incident response plan and identify any gaps or areas for improvement. These exercises can help to ensure that the incident response team is prepared to respond quickly and effectively to a real-world incident.

Action 2: Detection and Analysis

The second action recommended by NIST is detection and analysis. This action involves detecting cybersecurity incidents and assessing their impact. Organizations should have the right tools and technologies in place to detect cybersecurity incidents, such as network monitoring and intrusion detection systems. The incident response team should work to gather and analyze information about the incident to determine the scope, severity, and source of the incident.

Once the incident has been detected and analyzed, it is important for the organization to take appropriate action to contain and mitigate the incident. This may involve isolating affected systems, blocking malicious traffic, or disabling compromised accounts. The incident response team should work quickly and efficiently to minimize the impact of the incident and prevent further damage.

After the incident has been contained and mitigated, it is important for the organization to conduct a thorough post-incident analysis. This analysis should include a review of the incident response process, an assessment of the effectiveness of the organization’s security controls, and a determination of any necessary improvements or changes to prevent similar incidents from occurring in the future. By conducting a comprehensive post-incident analysis, organizations can improve their overall cybersecurity posture and better protect themselves against future threats.

Action 3: Containment, Eradication, and Recovery

The third action recommended by NIST is containment, eradication, and recovery. This action involves containing the incident to prevent further damage, eradicating the threat, and recovering from the incident. Organizations should have a clear process for containing the incident and minimizing the impact on the organization’s operations. The incident response team should work to eradicate the threat and recover critical data and systems.

It is important for organizations to regularly test their incident response plan to ensure that it is effective and up-to-date. This can involve conducting simulated incidents and evaluating the response of the incident response team. Regular testing can help identify any weaknesses in the plan and allow for improvements to be made before a real incident occurs.

Action 4: Post-Incident Activity and Review

The fourth action recommended by NIST is post-incident activity and review. This action involves documenting the incident, evaluating the effectiveness of the incident response plan, and identifying opportunities for improvement. Organizations should document the incident and conduct a post-incident review to identify areas for improvement in the incident response plan, processes, and procedures.

During the post-incident activity and review, it is important for organizations to analyze the root cause of the incident. This analysis can help identify any underlying issues that may have contributed to the incident and allow for corrective actions to be taken. Additionally, organizations should ensure that any necessary updates or changes to the incident response plan are made based on the findings of the review. By conducting a thorough post-incident review, organizations can improve their incident response capabilities and better prepare for future incidents.

Action 5: Communication and Coordination

The fifth action recommended by NIST is communication and coordination. This action involves communicating with stakeholders and coordinating with external organizations as needed. Organizations should have a communication plan in place that outlines the procedures for communicating with stakeholders, such as customers, employees, and regulatory agencies. The incident response team should work to coordinate with external organizations, such as law enforcement agencies or other affected organizations.

Effective communication and coordination during an incident response is crucial for minimizing the impact of a security breach. It is important for organizations to establish clear lines of communication and designate specific individuals or teams responsible for communicating with stakeholders and external organizations.
