What does incident response encompass?

Incident response encompasses the actions and processes taken to address and manage the aftermath of a security incident, disaster, or major event affecting an organization's information systems. This includes detecting, investigating, and resolving security breaches or cyberattacks to minimize impact and recover affected systems.

By focusing on responding to disasters and major events, incident response aims to restore normal operations as quickly as possible while ensuring that any vulnerabilities are addressed to prevent future incidents. It involves a systematic approach that includes preparation, identification, containment, eradication, recovery, and lessons learned.

The other choices, while important aspects of an organization's overall IT and security strategy, do not specifically define incident response. Implementing new technology strategies may help improve security but isn't a direct response to incidents. Conducting user training sessions enhances general security awareness but isn't focused on reactive measures following an incident. Performing routine software updates is crucial for maintaining security hygiene, yet it does not involve responding to incidents or events that have already occurred.
