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

The role of a Chief Information Security Officer (CISO) is pivotal in safeguarding an organization's information assets. The CISO is responsible for developing and implementing a comprehensive information security strategy that protects sensitive data from threats such as cyber attacks and data breaches. This involves not only crafting policies and measures to secure IT systems and networks but also ensuring compliance with regulatory requirements and industry standards regarding data protection.

In addition to strategic oversight, the CISO also leads a team of security professionals in monitoring threats, responding to incidents, and conducting risk assessments to identify vulnerabilities. They collaborate with other departments to promote a security-aware culture within the organization, ensuring that employees understand their role in maintaining security.

This role is distinct from others that focus on different operational aspects of the organization, such as marketing or human resources, which are not directly related to information security. Thus, the answer correctly highlights the CISO's responsibility in overseeing and enhancing the information security framework of the organization.
