Which term describes a method to prevent unauthorized data exposure?

The correct term that describes a method to prevent unauthorized data exposure is Data Loss Prevention (DLP). DLP encompasses strategies and tools that help organizations see and control their sensitive data, preventing it from being accessed or transmitted by unauthorized users. This is crucial in maintaining confidentiality and integrity of information, especially in environments where sensitive information such as personal identification, financial records, or intellectual property is handled.

DLP solutions typically involve monitoring data transfers, implementing encryption, enforcing access controls, and training employees on best practices for data security. By actively managing how data is shared and accessed, organizations can significantly reduce the likelihood of data breaches or leaks, thus safeguarding critical information from exposure.

The other terms provided do not pertain to the prevention of unauthorized data exposure. DML (Data Manipulation Language) is related to database operations such as inserting, updating, and deleting records. FAT (File Allocation Table) refers to a file system architecture for managing disk storage. DDoS (Distributed Denial of Service) attacks aim to overwhelm a network or service with traffic, disrupting access rather than protecting data.
