Incident prevention and mitigation are not key components of an incident response plan. They are part of a proactive approach to cybersecurity, which aims to prevent incidents from happening in the first place.

The primary goal of an incident response plan is to minimize the impact of an incident on the organization. This includes containing the incident, eradicating the threat, and restoring systems and data to their normal state.

Information Security Teams (ISTs) are responsible for developing and implementing an organization's information security program. They are not typically responsible for incident response.

The first step in an incident response plan is to detect and analyze the incident. This involves identifying the type of incident, the scope of the incident, and the potential impact of the incident.

Patching vulnerable systems is not a common method for containing an incident. It is a preventive measure that can be taken to reduce the risk of an incident occurring in the first place.

The final step in an incident response plan is to communicate and coordinate with stakeholders. This includes providing updates on the status of the incident, coordinating the response effort, and communicating with the media.

After-action reviews are not a type of incident response exercise. They are conducted after an incident has occurred to evaluate the response effort and identify areas for improvement.

An incident response plan serves all of the purposes listed above. It defines the roles and responsibilities of incident response team members, provides a step-by-step guide for responding to incidents, and ensures that all incidents are handled in a consistent manner.

Cost per incident is not a common type of incident response metric. It is a financial metric that can be used to measure the overall cost of an incident.

The most important factor to consider when developing an incident response plan is the specific threats that the organization faces. This will help to ensure that the plan is tailored to the organization's unique needs.

Penetration testing tools are not a common type of incident response tool. They are used to identify vulnerabilities in an organization's systems and networks.

All of the methods listed above can be used to test an incident response plan. Tabletop exercises are a good way to test the plan's overall effectiveness, while simulation exercises can be used to test the plan's specific procedures. Walkthrough exercises can be used to test the plan's technical aspects.

On-the-job training is not a common type of incident response training. It is a general type of training that can be used to teach employees how to perform their jobs.

All of the things listed above are important to remember when responding to an incident. Staying calm and not panicking will help you to think clearly and make good decisions. Following the incident response plan will ensure that you are taking the appropriate steps to respond to the incident. Communicating with stakeholders will keep them informed of the status of the incident and help to ensure that everyone is working together to resolve the incident.

Incident containment policy is not a common type of incident response policy. It is a specific type of policy that defines the steps that should be taken to contain an incident.
