Who is typically responsible for developing and maintaining an Incident Response Plan?

The cybersecurity or information security team is typically responsible for developing and maintaining an Incident Response Plan because they possess the specific expertise and knowledge related to cyber threats, vulnerabilities, and the technologies used within the organization's infrastructure. This team understands the risks associated with information systems and can design a response plan that effectively addresses potential incidents.

Furthermore, they are likely to collaborate with various other departments, such as legal and human resources, to ensure the plan complies with laws and regulations while aligning with organizational policies. The information security team is also best equipped to assess incidents, coordinate responses, conduct post-incident analysis, and implement improvements based on lessons learned, making them critical to the effectiveness of the incident response process.

The other departments listed, such as human resources, marketing, and legal, may have supporting roles in incident response, but they do not have the specialized focus on the security landscape that is essential for developing and maintaining an effective Incident Response Plan.
