Question: 1 / 400

With regard to network security, why would an incident responder enforce system isolation?

To improve system performance

To ensure that there is no interface between a compromised system and the rest of the network

Enforcing system isolation is a critical step for an incident responder when dealing with network security breaches. This practice is primarily aimed at ensuring that there is no interface between a compromised system and the rest of the network. By isolating the affected system, the incident responder can prevent the spread of malware or further compromise of network resources, thereby containing the threat.

Isolating a compromised system limits the ability of attackers to move laterally through the network, potentially accessing sensitive data or additional systems. It establishes a controlled environment for investigation and remediation without the risk of impacting other systems. This protective measure is essential during an incident response to preserve evidence, analyze the breach, and implement recovery strategies effectively without jeopardizing the entire network's integrity.
