We have released the Rublon PAM module pam_rublon that enables you to protect SSH logins to your cloud and datacenter Linux servers using Rublon’s multi-factor authentication (2FA/MFA).

Rublon for Linux SSH works with password-based logins as well as with SSH key-based authentication.

Quick Login Approval using Auto Push

Rublon’s module for Linux SSH enables you to send users a Mobile Push request automatically after they enter valid login credentials. Users must have the Rublon Authenticator mobile app installed in order to use Mobile Push.

Besides Mobile Push, the following authentication methods are available for Linux SSH:

Easy Install with Linux Packages

In order to make it easy for system administrators to deploy Rublon throughout their infrastructure, we have made install packages available for the following Linux distributions: CentOS (6, 7, 8), Debian (9, 10) and Ubuntu (16.04, 18.04).

Install packages for additional Linux distributions will be made available based on customer demand. If you are using a distribution that does not have an install package available yet, please reach out to Rublon Support.

2FA/MFA for Sudo Elevation

Rublon’s Linux SSH module enables you to enforce 2FA/MFA for sudo elevation.

2FA/MFA for SFTP

Rublon enables you to protect logins via SFTP using the Mobile Push 2FA/MFA authentication method with Auto Push turned on.

When using an FTP software client like Transmit, users will receive a Mobile Push login approval request to their phone that they must approve before being granted access to the server.

2FA/MFA for SCP

Protecting SCP connections with Rublon’s 2FA/MFA is also possible.

When using the SCP command, users will receive a Mobile Push login approval request to their phone that they must approve before the command is executed.
