Which of the following best describes an incident response team?

An incident response team is fundamentally characterized by its focus on managing security incidents. This dedicated group is specifically trained and equipped to respond to security breaches, system outages, data leaks, and other types of incidents that can compromise an organization's security posture. The team's primary responsibilities include identifying the incident, containing its impact, eradicating the threat, recovering affected systems, and implementing lessons learned to prevent future occurrences.

The other options illustrate different functions that do not align with the core mission of an incident response team. Monitoring social media pertains to threat intelligence and public perception rather than directly managing incidents. Routine IT tasks are typically handled by operational or support teams that focus on day-to-day technology management. Finally, a legislative body overseeing security regulations would deal with compliance and policy-making, which is distinct from the direct response to security incidents that an incident response team would engage in. Thus, option C accurately describes the essential role and purpose of an incident response team in the context of cybersecurity.
