What does "incident response" entail?

Incident response refers to an organized and structured approach taken by an organization to prepare for, detect, respond to, and recover from security breaches or cyber incidents. This process is crucial for minimizing damage and protecting sensitive information. It involves several key phases, such as preparation, detection, containment, eradication, recovery, and lessons learned, ensuring that an organization can effectively manage incidents when they occur.

In contrast, the other options do not align with the definition of incident response. Marketing strategies relate to promoting products or services, designing computer networks focuses on the architecture of IT infrastructure, and upgrading software systems pertains to enhancing or replacing existing software for improved functionality. None of these options involve the specific processes or protocols necessary for effectively managing security incidents.
