O365 Getting Spoofed from Another Country
I have a Client where email is being sent out redirecting closing agents where to wire money to.
Called Microsoft and we put in a rule that no email can be sent or relayed through this DOMAIN using this feaure:
https://knowbe4.zendesk.com/hc/en-us/articles/212679977-Domain-Spoof-Prevention-in-Exchange-2013-2016-Office-365
But it still happens....With MS Tech Support we Tracked email Headers some emails were coming from an IP in England...So we blocked it Then it started coming from an IP in Germany...We blocked that....
How Can I protect my client's O365 Accounts from Spoofing???

Security
Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection. Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
