The primary objective of incident response in ICS environments is to restore normal operations as quickly as possible, while also ensuring the safety and security of the system.

Denial-of-service attacks are not as common in ICS environments as they are in traditional IT environments, as ICS systems are typically designed to be resilient to this type of attack.

The first step in the incident response process is to identify the incident, which involves gathering information about the incident, such as the time and date it occurred, the systems affected, and the potential impact.

Applying security patches is not a common containment measure in ICS environments, as it can introduce new vulnerabilities and disrupt operations.

An incident response plan provides a roadmap for responding to incidents, assigns roles and responsibilities for incident response, and documents the incident response process.

Applying security patches is not a common eradication measure in ICS environments, as it can introduce new vulnerabilities and disrupt operations.

The final step in the incident response process is to recover from the incident, which involves restoring affected systems to normal operation and implementing measures to prevent future incidents.

Applying security patches is not a common recovery measure in ICS environments, as it can introduce new vulnerabilities and disrupt operations.

A post-incident review is conducted to identify lessons learned from the incident, improve the incident response plan, and assign blame for the incident.

Ignoring incidents until they become major problems is not a common best practice for incident response in ICS environments, as it can lead to more severe consequences and disruption.

The incident commander is responsible for overseeing the incident response process, making decisions about how to respond to the incident, and coordinating the activities of the incident response team.

Lack of funding for ICS security is not a common challenge in incident response in ICS environments, as most organizations recognize the importance of investing in ICS security.

An incident response exercise is conducted to test the incident response plan, train incident response team members, and identify gaps in the incident response process.

Mean time to recover from an incident is not a common metric for measuring the effectiveness of incident response in ICS environments, as it can be difficult to measure accurately.

The best way to prevent incidents in ICS environments is to implement a layered security approach, educate employees about ICS security, and regularly patch and update ICS systems.
