Incident response in cybersecurity refers to an organizations processes and technologies for detecting and responding to cyber threats, security breaches, or cyber attacks. The goal of incident response is to prevent cyber attacks before they happen and to minimize the cost and business disruption resulting from any cyber attacks that occur. Incident response is a specialized form of incident management, which involves the monitoring and detection of security events on a computer or computer network, and the execution of proper responses to those events.

An incident response plan (IRP) is a documented, systematic process that defines how an organization should deal with a cybersecurity incident. Ideally, an organization defines incident response processes and technologies in a formal IRP that specifies exactly how different types of cyber attacks should be identified, contained, and resolved. An effective incident response plan can help cybersecurity teams detect and contain cyber threats and restore affected systems faster, and reduce the lost revenue, regulatory fines, and other costs associated with these threats.

The incident response process is a set of steps performed by incident response teams to prevent, detect, and mitigate security incidents. The process is a recurring one that is improved with each cycle by feedback and a review of any actions taken. The steps involved in incident response include:

1. Preparation: This step involves preparing for potential incidents by developing an incident response plan, identifying critical assets, and training personnel.

2. Identification: This step involves detecting and identifying potential security incidents by monitoring systems and networks for suspicious activity.

3. Containment: This step involves containing the incident to prevent further damage by isolating affected systems and networks.

4. Investigation: This step involves investigating the incident to determine the cause, scope, and impact of the incident.

5. Eradication: This step involves removing the threat from affected systems and networks.

6. Recovery: This step involves restoring affected systems to normal operations and evaluating the source of the incident to identify improved security measures to prevent its recurrence.

Incident response is typically handled by an organizations cybersecurity team, which may include a Computer Security Incident Response Team (CSIRT) . The CSIRT is responsible for managing the response to an emergency security incident.

In summary, incident response in cybersecurity involves the processes and technologies used by organizations to detect and respond to cyber threats, security breaches, or cyber attacks.
