2FA for Veeam Servers with Duo

Something that all Veeam administrators should consider is how secure the underlying servers running your Veeam software really are. To help improve security I always try and run through a few recommendations with each Veeam administrator I work with,

  • Inbound connectivity to backup servers from the Internet must not be allowed (3389 anyone?)
  • Any accounts used for RDP access must not have Local Administrator privileges on jump servers, and you must never use the saved credentials functionality for RDP access or any other remote console connections.
  • Ensure timely guest OS updates on backup infrastructure servers

A good resource for keeping up to date on Veeam security recommendations is here. I like to check it out every 3-6 months to ensure I’m still making the right recommendations to my customers.

One other thing I like to recommend in addition to the best practices above is enabling 2FA (Two-Factor Authentication) for all logon sessions to underlying servers running Veeam components such as the VBR server, proxies and especially repositories.  With 2FA, even if an attacker illegally acquires the correct username and password, the attacker is also required to gain access to the device used to receive the 2FA verification code. Often this device is a mobile phone or a security token which can easily be disabled if lost or stolen.

While 2FA for Veeam consoles is presently not possible (it is a heavily requested feature though) and even with 2FA for login sessions there is still a risk that an attacker can access Veeam infrastructure via a Veeam Console running from another machine. This is why off-site/offline backups are so so critical in today’s world of ransomware. Leveraging Veeam Cloud Connect Backup with it’s Insider Protection feature is a great way to easily protect against this kind of risk.

This post will go into detail on how to quickly and easily and enable 2FA for RDP and local logon sessions connecting to your Veeam server.
