DMARC – uncover email spoofing

When it comes to email spoofing. You can’t fix what you don’t know is happening.

Plainly put – spoofing is the very uncool act of sending email using someone else’s email address (as the “from” address). This so that the receiver of the message thinks that the message is legit, to “sell” the receiver the lie it’s coming from someone other than them. People are naturally more likely to read email if they think the sender is above-board.

Enter DMARC – a work in progress email authentication and reporting standard.

DMARC is a way to make it easier for email senders and receivers to determine whether or not a given message is legitimately from the sender, and what to do if it isn’t. This makes it easier to identify spam and phishing messages, and keep them out of inboxes.

Never mind the work in progress, DMARC is used by all the big players. Given Gmail, Office 365, and other email providers dominate email traffic, informed consensus says DMARC really is non-negotiable today.

How else can you get reporting on all messages that claim to come from your domain?  Only from email providers/email systems who’ve implemented the DMARC standard. You’ll get reports on how many illegitimate messages are using your domain, and where the emails are coming from.

Microsoft Azure File Sync

This is where it all comes together. At last, from: https://azure.microsoft.com/en-us/blog/score-one-for-the-it-pro-azure-file-sync-is-now-generally-available/

Azure File Sync replicates files from your on-premises Windows Server to an Azure file share, just like how you might have used DFS-R to replicate data between Windows Servers. Once you have a copy of your data in Azure, you can enable cloud tiering—the real magic of Azure File Sync—to store only the hottest and most recently accessed data on-premises.

And since the cloud has a full copy of your data, you can connect as many servers to your Azure file share as you want, allowing you to establish quick caches of your data wherever your users happen to be. As mentioned above, in simple terms, Azure File Sync enables you to centralize your file services in Azure while maintaining local access to your data.

Microsoft Azure Files and Azure File Sync

Azure Files offers fully managed file shares in the cloud that are accessible via the industry-standard Server Message Block (SMB) protocol. Yes, this is a big deal, transformational even… the file server in the Cloud is fast becoming a practical reality.

You can mount Azure file shares concurrently on cloud or on-premises deployments of Windows, Linux, and macOS. You also can cache Azure file shares on Windows Server machines by using Azure File Sync for fast access close to where the data is used.
