Which approach is NOT effective in protecting sensitive information?

The approach that allows everyone to access all data is ineffective in protecting sensitive information because it undermines the principle of data minimization and access control. Sensitive information should only be accessible to individuals who have a legitimate need to know based on their roles and responsibilities within the organization. Granting unrestricted access increases the risk of accidental disclosures, malicious actions from insider threats, or data breaches, as more individuals will have the opportunity to interact with, misuse, or mishandle that information.

In contrast, conducting regular audits helps identify vulnerabilities and compliance issues within the data protection framework, thereby reinforcing security practices. Providing employee training ensures that staff are aware of best practices, potential threats, and the importance of safeguarding sensitive information. Implementing encryption adds a layer of security to protect data both in transit and at rest, making it unreadable to unauthorized users even if they gain access. Each of these methods strengthens overall data protection efforts, while unrestricted access directly contradicts effective security strategies.
