In which industry did the first case study demonstrate the use of IAM to prevent data breaches?RetailHealthcareEducationManufacturing

The first case study demonstrating the use of Identity and Access Management (IAM) to prevent data breaches was in the Healthcare industry.

Explanation:

The healthcare industry has long been a primary target for data breaches due to the sensitive nature of the information it handles, such as patient records and health histories. As a response to threats, healthcare organizations were among the first to implement IAM solutions. These systems help ensure that only authorized personnel have access to specific data, thereby enhancing security and compliance with regulations like HIPAA (Health Insurance Portability and Accountability Act). The initial case studies involved tracking access to electronic health records, managing user roles, and implementing strict authentication methods. The success of these implementations not only improved security but also set a precedent for other sectors to adopt IAM practices to mitigate data breach risks.

Thus, the correct answer is Healthcare.
