What is the purpose of incident response in email security?

The purpose of incident response in email security is fundamentally about managing the response to email security breaches. When an incident occurs—such as a phishing attack, data breach, or unauthorized access—an effective incident response plan is essential for identifying the threat, mitigating its impact, and restoring normal operations. This process involves several crucial steps, including detection, assessment, containment, eradication, recovery, and lessons learned.

Having a structured incident response plan ensures that organizations can rapidly and effectively address vulnerabilities and respond to emerging threats. This includes documenting incidents, analyzing how they occurred, and implementing measures to prevent similar issues in the future. Overall, the goal is to protect sensitive information, maintain trust with users, and comply with relevant regulations.

In contrast, options that involve creating more email accounts, enhancing spam filter settings, or developing marketing strategies do not align with the core focus of incident response, which is specifically centered on managing and mitigating security incidents and risks.
