How does MFA for remote access work?

We install a firewall rule on the target machine, which blocks all incoming remote desktop connections (RDP on Windows, SSH/VNC on Mac OS and Linux). When you click "unlock" in the portal, we send a message to the Elpha Secure installation to temporarily open a hole in the firewall.

Initially, this hole is only open to what appears to be your source IP address, though we also provide the option to unlock it for all IP addresses. When a user attempts to log in, they'll still have to provide valid operating system credentials.

After the login window expires, we reinstate the firewall rule: this continues to block all new incoming connections, but allows any existing connections to continue.

Does Elpha Secure provide MFA for other types of services?

Since the software is installed on an endpoint (i.e. your computer), we can provide MFA for access to any services provided by that endpoint.

For cloud services, we may be able to help you enable MFA support that exists within those services. In some cases, we can replace the authentication mechanism for cloud services to use Elpha Secure instead (thus adding MFA).

Does Elpha Secure support other authentication modes for MFA?

While SMS authentication is our default, we understand that some people might want a higher level of security or an avenue that doesn't rely on cell network coverage.

If you prefer, you can use one-time pad authentication through Google Authenticator or FreeOTP. We may be able to support other mechanisms, too, like hardware security tokens. Does this sound like something that would suit your operation? Please reach out to hello@elphasecure.com.

What comes next

MFA is your first step to a strong remote working strategy; adding a virtual private network (VPN) can take this to the next level. Elpha Secure will be introducing a VPN as an optional feature, but it's a great way to ensure a secure connection from anywhere, at every point in the chain.
