A rule set is a collection of security rules. Create a rule set to group security rules that you want the Rule Engine to apply to SQL request statements. Assign the rule set to a connection rule. The Rule Engine applies the rule set if the connection request matches the conditions that the connection rule defines.
A security rule set can contain a combination of rules that perform different tasks. You can add security rules that mask data, block requests, rewrite the SELECT statement, or replace a part of the SELECT statement. To organize rules within a rule set, you use rule folders to group security rules that apply the same action. For example, group rules that use the mask action in one rule folder, and group rules that use the block action in a different rule folder.
