About Policy Dictionaries

Dictionaries are comma-separated lists of distinct values linked to unique names for easy reference in policy rules. They are beneficial for managing large lists, such as URLs or IP addresses, where maintaining consistency across multiple rules can be cumbersome. Policy Dictionaries provides a centralized approach to manage such lists and allows administrators to create and modify entries in a single location. Changes are automatically reflected wherever the dictionary is used. This central repository facilitates the reuse of defined terms across multiple DLP policies, streamlining management and enhancing the accuracy and uniformity of rule enforcement.

NOTE: When creating a DLP Policy Rules and Exceptions, you can add the policy dictionaries for Keywords, File Names, File Path/Folder, and File/Folder Collaboration.

Use Case: Preventing the leakage of sensitive project code names in an organization can be difficult without Policy Dictionaries. As new projects start and code names change, administrators must manually locate and update each relevant DLP rule, which requires entering the entire list of code names. This process is both time-consuming and prone to errors.

Policy Dictionaries simplify this task by providing a single dictionary that contains all current project code names. When a new project is initiated, the administrator only needs to update the central dictionary, and this change automatically updates all DLP rules that reference it, ensuring consistent and accurate enforcement of policies.
