How does Oracle Analytics ensure data security?

Oracle Analytics ensures data security primarily through user authentication, access controls, and data encryption, which are critical components in protecting sensitive information and maintaining data integrity.

User authentication verifies the identity of users before granting access to data, ensuring that only authorized personnel can access specific datasets. This process helps prevent unauthorized access and potential data breaches. Access controls work in conjunction with authentication by establishing permissions and roles, allowing administrators to limit what users can see or do within the system. Different users may require varying levels of access depending on their roles within the organization, thus enhancing security by minimizing exposure to sensitive data.

Data encryption further strengthens data security by converting data into a coded format that can only be read by those who have the appropriate decryption keys. This ensures that even if data is intercepted during transmission or accessed by unauthorized users, it remains protected and unreadable.

While the other options present different approaches, they do not encompass the comprehensive measures that Oracle Analytics employs for securing data. For instance, displaying all data openly would completely compromise data security, and using a public cloud service without additional protection increases vulnerability. Limiting data storage does not inherently ensure security, as it could restrict necessary access to important information, thereby hindering analysis and decision-making.
