Which role can act as a liaison between lower-level users and management in security incidents?

The role of a Chief Information Security Officer (CISO) is pivotal in bridging the gap between the lower-level users and management during security incidents. A CISO typically possesses both technical expertise and business acumen, making them well-suited to communicate effectively with various stakeholders. They can interpret and convey security concerns in a way that is understandable to non-technical personnel while also presenting the implications of these issues to upper management.

In the context of security incident response, this role is crucial for facilitating information flow about incidents, ensuring that management is kept informed of the situation, its potential impact, and any necessary actions. They often lead the strategy and policy decisions regarding incident response and are involved in the decision-making process at the highest level. This central position allows them to advocate for the necessary resources and support from management while ensuring that the concerns and insights from lower-level users are properly represented in the decision-making process.

The other roles mentioned do not serve this liaison function effectively. They are more specialized and do not have the same level of cross-functional engagement or authority as a CISO.
