Certified Incident Handler (CIH) Practice Ecam

What should incident handlers prioritize when investigating email-related security incidents?

1. Resolving API integration issues

2. Identifying the source of the breach

3. Training employees in cybersecurity

4. Updating the organization’s email service

The correct answer is: Identifying the source of the breach

Prioritizing the identification of the source of the breach is crucial when investigating email-related security incidents. Understanding where the breach originated allows incident handlers to assess the extent of the incident, determine how attackers gained access, and formulate an effective response strategy. This step is vital for stopping further unauthorized access, protecting sensitive information, and preventing future incidents. By tracing the source, incident handlers can identify compromised systems, investigate vulnerabilities, and strengthen security measures against similar threats. While the other options are relevant to a comprehensive cybersecurity strategy, they do not directly address the immediate needs of responding to an active email-related security incident. Resolving API integration issues and updating the organization's email service may be important maintenance tasks but do not directly contribute to the urgent response required in a breach scenario. Training employees in cybersecurity is essential for long-term deterrence against breaches, but it cannot resolve the immediate challenges posed by a specific incident. Therefore, focusing on identifying the source of the breach is the most critical action for incident handlers in this context.
