Final answer:
The person responsible for handling a data breach at a bank involving the theft of personal identification information would be the Chief Information Officer (CIO), who oversees IT and cybersecurity measures.
Step-by-step explanation:
When unknown hackers hack into the network security of a bank and steal personal identification information of clients, the primary person responsible for handling the situation would be the Chief Information Officer (CIO). The CIO is responsible for the information technology and computer systems that support enterprise goals, which includes ensuring online privacy and security. The role involves managing IT staff, establishing best practices for electronic data processing and computer systems operations, as well as designing and implementing robust cybersecurity measures to protect against data breaches.
In the face of a security breach, the CIO would typically lead a response team to assess the damage, communicate with key stakeholders like customers and law enforcement, and mitigate any immediate threats to additional data loss. This also includes working on a recovery plan and strengthening security infrastructure to prevent future incidents. While the Chief Financial Officer (CFO) may be concerned with financial implications, the Chief Marketing Officer (CMO) with public relations, and the Chief Operating Officer (COO) with operational continuity, it is the CIO's direct responsibility to address and resolve cybersecurity incidents.
