Reporting and Documentation

Reporting and documentation are important aspects of incident response planning. Organizations must document incidents for compliance and reporting purposes and provide information for future incident response planning. MSS providers can assist organizations in reporting and documentation by providing templates and workflows for incident reporting and documentation and by helping organizations comply with regulatory requirements.

There are various frameworks that organizations can use to guide their reporting and documentation during incident response planning. Some commonly used frameworks include

NIST Cybersecurity Framework

Developed by the National Institute of Standards and Technology (NIST), this framework provides a comprehensive approach to managing and reducing cybersecurity risk. It includes five core functions: Identity, Protect, Detect, Respond, and Recover. Organizations can use this framework to guide their incident response planning and reporting.

ISO 27001

This international standard provides information security management systems (ISMS) framework. It includes a set of controls organizations can implement to manage and protect their information assets. ISO 27001 can be used to guide incident response reporting and documentation.

SANS Incident Handling Framework

Developed by the SANS Institute, this framework provides a step-by-step approach to incident handling. It includes six phases: Preparation, Identification, Containment, Eradication, Recovery, and Lessons Learned. Organizations can use this framework to guide their incident response planning and reporting.

CIS Critical Security Controls

Developed by the Center for Internet Security, this framework provides a prioritized set of best practices for securing an organization's IT systems and data. It includes 20 critical security controls organizations can implement to improve their security posture. The CIS Critical Security Controls can guide incident response reporting and documentation.

These frameworks provide organizations with a structured approach to incident response planning and reporting and can help ensure that incidents are documented consistently and comprehensively. Organizations should choose a framework that aligns with their business needs and security requirements.

2. Continuous Improvement

Analyzing IR Effectiveness

Analyzing incident response effectiveness is an important component of incident response planning. It helps organizations identify areas for improvement and ensure that their incident response plan (IRP) remains effective in the face of evolving cyber threats. MSS providers can assist organizations in analyzing incident response effectiveness by providing metrics and analytics to measure the effectiveness of the IRP, and by recommending improvements to the IRP based on the analysis.

Several methods can be used to analyze the effectiveness of incident response:

Post-Incident Review

This is a review process conducted after an incident has occurred to assess the effectiveness of the incident response plan. The review should include an analysis of the response process, the effectiveness of the response team, and the efficiency of the tools and technologies used.

Key Performance Indicators (KPIs)

Organizations can use KPIs to measure the effectiveness of their incident response program. Some examples of KPIs include time to detect an incident, time to contain an incident, and time to resolve an incident.

Tabletop Exercises

These exercises simulate an incident and test the response plan and the effectiveness of the response team. The exercise results are use to identify gaps and areas for improvement.

Incident Simulation

Like tabletop exercises, incident simulations create a realistic environment for incident response testing. These simulations can measure the effectiveness of the response team and the response plan.

Incident Metrics

Incident metrics can be used to measure the effectiveness of the incident response process. These metrics can include the number of incidents detected, the number of incidents successfully contained, and the number of incidents resolved within a specific timeframe.

By analyzing the effectiveness of the incident response, organizations can identify areas for improvement and refine their incident response plan to ensure they are prepared for future incidents. Combining methods is important to get a comprehensive view of incident response effectiveness.

Updating and Testing the IR Plan

Updating and testing the IRP is crucial for ensuring it remains effective and relevant. MSS providers can assist organizations in updating and testing the IRP by providing expertise and resources to update the IRP based on changes in the threat landscape and by conducting regular testing and simulation exercises to ensure that the IRP is effective in the event of a real incident.

To update and test an incident response plan, organizations should follow these steps:

Review the Plan

Organizations should review the incident response plan regularly to ensure that it is up to date and reflects the current threat landscape and organizational structure.

Identify Gaps and Areas for Improvement
