Rule Exceptions

Sometimes you may want to create exceptions to a ruleClosed Set of traffic parameters and other conditions in a Rule Base (Security Policy) that cause specified actions to be taken for a communication session. in the DLP policy.

For example, a public health clinic that must comply with the Health Insurance Portability and Accountability Act (HIPAA), should not allow patient records to leave the clinic's closed network. However, the clinic works with a specific social worker in a city office, who must have the records on hand for the patients' benefit. As the clinic's Security Administrator, you create an exception to the rule, allowing this data type to be sent to the specific email address. You could make this case even better: in the exception, include a secondary data type is a Dictionary of patient names who have signed a waiver for the social worker to see their records. Thus, with one rule, you ensure that only records that the social worker is allowed to see are sent to the social worker's office. DLP prevents anyone from sending records to an unauthorized email address. It ensures that no employee of the clinic has to deal personal requests to have the records sent to unauthorized destination - it simply cannot be done.
