The CFO Just Informed You That One of Their Team

The CFO just informed you that one of their team members wire-transferred money to the wrong account because they received an email that appeared to be from the CFO. The CFO has provided a list of all users that may be responsible for sending wire transfers. The CFO also provided a list of banks the company sends wire transfers to. There are no external users that should be requesting wire transfers. The CFO is working with the bank to resolve the issue and needs your help to ensure that this does not happen again. What two actions should you take? (Choose two.)

A) Configure objectionable content to reject messages with the words "wire transfer."
B) Verify that DMARC, DKIM, and SPF records are configured correctly for your domain.
C) Create a rule requiring secure transport for all messages regarding wire transfers.
D) Add the sender of the wire transfer email to the blocked senders list.
E) Enable all admin settings in Gmail's safety > spoofing and authentication.
