What describes the immediate action taken to isolate a system in the event of a breach?

1. Containment

2. Destruction

3. Isolation

4. Limitation

The correct answer is: Containment

The term that describes the immediate action taken to isolate a system in the event of a breach is containment. This action is critical to prevent the further spread of the breach, limit damage, and protect other systems and data within the network. Containment involves implementing measures to restrict access to the compromised system while retaining its integrity for investigation purposes. In a security incident, swift containment helps to minimize the potential impact of the breach on the organization. It can involve isolating the affected system from the network or applying temporary security controls to prevent the attack's lateral movement to other systems. This proactive approach not only addresses the immediate threat but also plays a vital role in the overall incident response strategy. The other terms do not accurately describe this urgent action. Destruction implies permanently removing or deleting data or systems, which is not the focus in initial response efforts. Isolation, while similar to containment, does not encapsulate the broader strategy of managing the breach and limiting its effects. Limitation refers more generally to restricting actions or functions but lacks the specific connotation related to breaches and incident response. Thus, containment is the most precise and relevant term in the context of cyber security response to breaches.
