Which of the following is an outcome of a well-defined security incident response plan?

A well-defined security incident response plan is crucial for minimizing damage during a security breach. This plan outlines the steps that organizations must take when a security incident occurs, ensuring a rapid and organized response. By having predefined roles, responsibilities, and procedures, the organization can effectively contain the incident, limit its impact, and mitigate potential losses.

An efficient incident response allows teams to quickly identify the breach's scope, assess vulnerabilities, and implement measures to prevent further damage. It also helps in preserving evidence for investigation, which is critical for understanding how the breach occurred and for compliance with regulatory requirements. Consequently, the ability to respond promptly and effectively can significantly reduce downtime, protect sensitive data, and uphold the organization's reputation in the face of an attack.

Other choices, while they might be beneficial in their own right, do not directly relate to the primary objective of a security incident response plan.
