Which stakeholder would typically be responsible for developing an incident response plan and its estimated budget?

The security manager is typically responsible for developing an incident response plan and its estimated budget. This role encompasses overseeing the organization's cybersecurity strategies and ensuring that incident response is effectively integrated into the overall security framework. The security manager is tasked with identifying potential threats, establishing protocols for response, and allocating adequate resources for these initiatives.

Creating an incident response plan involves careful consideration of potential risks, response strategies, team roles, and communication pathways. The security manager must work to align the incident response plan with business objectives and compliance requirements, which includes managing the budget effectively to support necessary tools, training, and personnel.

While other roles are important in the broader context of cybersecurity management, the security manager is specifically positioned to take on the responsibility of crafting a comprehensive plan and justifying its financial implications, thereby ensuring the organization is prepared for potential incidents.
