As a CISO tasked with protecting sensitive customer data, which type of control should be implemented?

Implementing a technical control is crucial for protecting sensitive customer data because these controls involve the use of technology to mitigate risks and secure data. Technical controls include tools and solutions such as encryption, firewalls, intrusion detection systems, and access control mechanisms, which are specifically designed to prevent unauthorized access and breaches. These measures directly address the vulnerabilities in systems and networks where sensitive data resides, ensuring that data is only accessible to authorized users and is protected against various types of cyber threats.

In the context of a CISO's responsibilities, employing technical controls aligns closely with the need for robust security measures that actively monitor, detect, and respond to potential incidents affecting sensitive information. This proactive approach establishes a strong security posture that protects customer data effectively.

Other types of controls, such as operational, managerial, and physical controls, play significant roles in a comprehensive security strategy but do not focus primarily on the technological safeguards necessary to maintain data confidentiality and integrity. While operational controls refer to the processes and procedures for personnel behavior, managerial controls involve policies and oversight from management, and physical controls protect the physical infrastructure, none of these directly employ the technology needed to respond to evolving cyber threats in real-time. Therefore, the implementation of technical controls is essential for a CISO focused on safeguarding sensitive
