Certified Incident Handler (CIH) Practice Ecam

Which guideline aids incident handlers during preparation for network security incidents?

1. Review historical attack vectors

2. Define live analysis laboratory configurations

3. Update antivirus definitions

4. Install intrusion detection systems on all endpoints

The correct answer is: Define live analysis laboratory configurations

The guideline that aids incident handlers during preparation for network security incidents focuses on defining live analysis laboratory configurations. This practice is essential because creating a controlled environment allows incident handlers to simulate attacks and analyze malware behavior without risking their production environment. By setting up specific configurations, including the types of operating systems, software, and networks to be used in simulations, handlers can practice their response strategies, enhance their skills, and ensure they are well-prepared for real incidents. Moreover, having a live analysis laboratory enables teams to gain insights into potential vulnerabilities and test different incident response techniques. It allows them to better understand the tools and methodologies that might be employed during an actual incident, thereby enhancing the organization's overall readiness and effectiveness in dealing with security threats. Reviewing historical attack vectors, while important, is more about understanding past incidents than about preparing for future ones in a practical setting like a lab. Updating antivirus definitions is a critical ongoing maintenance task but does not constitute a preparatory guideline for incident handling practices specifically. Installing intrusion detection systems is essential for protective measures but is more about prevention than preparation for handling an incident.
