 The correct flow of stages in an Incident Handling and Response (IH&R) process typically follows a structured approach that begins with Preparation, which is crucial for an effective response to incidents. This is followed by Incident Recording, where details of the incident are documented. Incident Triage is the next stage, where incidents are prioritized based on their impact. Containment strategies are then employed to limit the spread of the incident. Eradication involves removing the threat from the affected systems. Recovery is the process of restoring systems to normal operation. Finally, Post-Incident Activities involve learning from the incident and improving future response efforts.

References: The stages of the IH&R process are outlined in various EC-Council resources, including the EC-Council’s Certified Incident Handler (E|CIH) program and related training materials, which emphasize the importance of a structured and methodical approach to incident handling and response123.

The eradication stage is where the root cause of the incident is determined from the forensic results. This stage involves not only removing the threat from the affected systems but also identifying and fixing the vulnerabilities that were exploited. It’s crucial to understand how the incident occurred to prevent future occurrences. After the containment stage, where the immediate threat is isolated, eradication ensures that the threat is completely removed and that the root cause is addressed.

References: The EC-Council’s Certified Incident Handler (E|CIH) program outlines the stages of incident handling and response, which include preparation, identification, containment, eradication, recovery, and lessons learned. The eradication stage specifically deals with eliminating the threat and addressing the root cause based on forensic analysis. This information is covered in the E|CIH program and can be found in the official EC-Council learning resources1.

The Incident Response Procedures contain the performance measures and proper project and time management details. These procedures are designed to guide the incident response team through each phase of incident management, ensuring that all activities are performed efficiently and effectively. They include specific steps to follow, roles and responsibilities, timelines, and performance metrics to measure the effectiveness of the response.

References: The answer is verified as per the EC-Council’s SOC Analyst documents and learning resources, which outline the structure and content of incident response plans and procedures. For further study, refer to the EC-Council’s Certified SOC Analyst (CSA) course material and study guides, which provide detailed information on the incident response lifecycle, including preparation, identification, containment, eradication, recovery, and lessons learned. These resources will offer a comprehensive understanding of the procedures involved in managing and responding to security incidents.

After collecting the evidence in a forensic investigation, the next critical step is to create a Chain of Custody Document. This document is essential as it records the evidence’s chronological history, detailing every person who handled the evidence, the date/time it was collected, transferred, analyzed, or otherwise processed. This ensures the integrity and security of the evidence, maintaining its admissibility in legal proceedings.
