What is the baseline function of a Chief Information Security Officer (CISO)?

The baseline function of a Chief Information Security Officer (CISO) is to oversee and manage the organization's information security strategy. This role is critical in establishing and maintaining the organization's overall security posture, ensuring that policies, procedures, and practices are in place to protect sensitive information and mitigate risks related to cybersecurity threats.

The CISO is responsible for developing a comprehensive security framework that aligns with the organization's goals and complies with legal and regulatory requirements. This includes identifying potential security risks, implementing protective measures, and overseeing incident response plans. Additionally, the CISO plays a crucial role in educating and training employees on security best practices and advocating for a culture of security within the organization.

While overseeing employee training and managing the IT department are important components of an organization's operations, they are not the primary function of a CISO. The focus on enhancing performance metrics, although relevant, falls outside the core responsibilities specifically tied to information security strategy management. Thus, the role of the CISO directly aligns with overseeing and managing the organization's information security strategy, making it the correct answer.
