Email Collection Mitigation

Use of encryption provides an added layer of security to sensitive information sent over email. Encryption using public key cryptography requires the adversary to obtain the private certificate along with an encryption key to decrypt messages.

Use of two-factor authentication for public-facing webmail servers is also a recommended best practice to minimize the usefulness of user names and passwords to adversaries.

Identify unnecessary system utilities or potentially malicious software that may be used to collect email data files or access the corporate email server, and audit and/or block them by using whitelisting^[1] tools, like AppLocker,^[2],[3] or Software Restriction Policies^[4] where appropriate.^[5]
