Evaggelia needs to provide a set of minimum security requirements for email. What steps should she recommend for her organization to ensure that the email remains secure?

Encrypting and labeling sensitive email will ensure that it remains confidential and can be identified. Performing these actions only on sensitive email will reduce the cost and effort of encrypting all email, allowing only sensitive email to be the focus of the organization's efforts. Only encrypting highly sensitive email not only skips labeling but might expose other classifications of email that shouldn't be exposed.
