2.1 Chief Privacy Officer(CPO) and CISO

The roles of CPO and CISO are critical in contemporary organizations, especially given the increasing importance of data privacy and cybersecurity. While both roles focus on protecting information, they differ significantly in their areas of responsibility and expertise. This literature review examines the definitions, roles, responsibilities, and integration of CPOs and CISOs within organizations, highlighting their unique contributions and the interplay between these two positions.

The CPO is primarily responsible for overseeing an organization's data privacy strategy and ensuring compliance with relevant laws and regulations. The role of the CPO has gained prominence with the advent of stringent data protection regulations such as the General Data Protection Regulation(GDPR) in Europe and the California Consumer Privacy Act (CCPA) in the United States[10]. CPOs ensure that personal data is collected, stored, and processed in a manner that respects individuals' privacy rights and complies with legal requirements. CPOs also play a crucial role in risk management by identifying potential privacy risks and implementing measures to mitigate them[8]. They work closely with various departments within an organization to develop privacy policies and procedures, conduct privacy impact assessments, and train employees on data privacy best practices[11]. Moreover, CPOs often serve as the point of contact for data protection authorities and manage responses to data breaches and privacy-related incidents[9].

The CISO is responsible for an organization's overall information security strategy. This role encompasses protecting the organization's information assets from cyber threats and ensuring the confidentiality, integrity, and availability of data[12]. CISOs develop and implement comprehensive security policies, conduct regular security assessments, and lead incident response efforts in the event of a cyber attack[13]. CISOs must stay abreast of the latest cybersecurity trends and threats, adapting the organization's security posture accordingly. They are responsible for implementing technical controls such as firewalls, encryption, and intrusion detection systems, as well as promoting a security-conscious culture within the organization[5]. Additionally, CISOs often liaise with other executives to align the cybersecurity strategy with the organization's overall business objectives[14].

While the roles of CPOs and CISOs are distinct, their collaboration is essential for a holistic approach to data protection and cybersecurity. Effective communication and coordination between these officers can enhance an organization's ability to protect sensitive data and comply with legal requirements[6]. For instance, during a data breach, the CISO focuses on mitigating the threat and securing the network, while the CPO handles legal compliance and communication with stakeholders[7].

The literature underscores the importance of both CPOs and CISOs in safeguarding an organization's information assets. While their responsibilities differ, their collaboration is crucial for achieving comprehensive data protection and cybersecurity. Future research could explore the evolving dynamics between these roles as regulatory landscapes and cyber threats continue to evolve. This study focuses on CISOs due to the growing complexity of cyber threats and the critical role CISOs play in developing and implementing robust cybersecurity strategies, ensuring the protection of organizational data and systems.
