What are predefined dictionaries used for in Zscaler DLP?

Predefined dictionaries in Zscaler Data Loss Prevention (DLP) serve the specific purpose of identifying sensitive data types like Payment Card Information (PCI), Personally Identifiable Information (PII), and Protected Health Information (PHI). These dictionaries contain patterns and rules that the DLP system uses to scan and detect data that could potentially be sensitive, helping organizations to ensure compliance with regulatory requirements and protect their sensitive information effectively.

By using predefined dictionaries, organizations can streamline their data protection strategies, allowing for efficient monitoring and safeguarding of critical data during its transit across networks. This is essential for preventing unauthorized access, loss, or exposure of sensitive information, thus maintaining data privacy and integrity.

In contrast, other choices might deal with different aspects of data management:

• Categorizing file types relates to organizing content based on its format rather than its sensitivity.

• Storing user credentials focuses on authentication and identity management, not data sensitivity detection.

• Defining user access levels pertains to permissions within a system rather than identifying sensitive information.

Thus, the effective identification of sensitive data within the context of DLP is the primary and correct focus of using predefined dictionaries in Zscaler.
