IMSVA evaluates data in an email message against a set of defined rules. Rules determine data that must be protected from unauthorized transmission and the action that IMSVA performs when it detects transmission.
IMSVA rules have the following components:
Mail Route: A set of sender and recipient email addresses or groups, or an LDAP user or group to which the policy is applied. You can use the asterisk (*) to create wildcard expressions and simplify route configuration.
Filter: A rule or set of rules that apply to a specific route. In TMCM, you can set rules for protecting against data loss using templates.
Action: The action that IMSVA performs if the filter conditions are met.
