What is the main objective when addressing a security incident?

The main objective when addressing a security incident focuses on containment. Containment involves taking immediate steps to limit the impact of the incident and to prevent it from spreading further. This is a critical phase in the incident response process because it aims to isolate affected systems or networks, allowing for a more secure environment in which to investigate and address the incident.

While early detection and assessment are important components of an effective incident response strategy, they serve as preparatory and evaluative steps rather than the immediate action taken during an incident. Early detection helps to identify incidents as soon they occur, which is beneficial for minimizing damage, while assessment is about evaluating the incident's impact and understanding its scope. However, in the context of responding to an ongoing security incident, containment is prioritized to mitigate damage and secure the environment for further analysis and remediation efforts.

In conclusion, containment is a crucial step that comes after incidents are detected and assessed, making it the focal point of response efforts during a security incident.
