There is no replacement for crafting an incident response plan and assigning dedicated individuals to be responsible for it. An incident response team is a group of people — either IT staff with some security training or full-time security staff in larger organizations — who collect, analyze, and act upon information from an incident. An incident response plan is not complete without a team that can carry it out — the Computer Security Incident Response Team (CSIRT). Important decisions at this stage are from which time and date to restore operations, how to verify that affected systems are back to normal, and monitoring to ensure activity is back to normal.
