Forcing SSH-MFA Two-Factor Authentication

How-to force Multifactor Authentication when someone uses SSH to access a server or container protected by ZeroLock®.

Ensuring usage of SSH-MFA two-factor authentication, requires a multi-step process simplified by the ZeroLock Management Console (ZMC).

Create and Add a New Rule

1. In the ZeroLock Management Console (ZMC) go to the Control Policies | Rules page then click Actions | Add New Rule. 
   
   
   
2. On the Add New Rule screen, complete the items using the table below.  When done click CREATE.
   
   

   Rule Name	Authenticate all SSH connections
   Description	This rule will force SSH MFA for all assigned Endpoints
   Rule Type	SSH-MFA
   IP Address	Leave as default
   Day/Time	Leave as default
   Start/End	Leave as default
   Action	Authenticate

Create a New Control Policy 

1. As shown below, go to the Control Policies | Policies page and click Add New Policy. 
   
   
   
2. Using the table, complete the required entries.   
   

   Name	Force SSH Authentication
   Description	This policy will force SSH authentication to all assigned endpoints.
   Add Rules	Clicking the Add Rules button brings up the Policy Rules screen.

   
   
   
3. On the Policy Rules screen, use the TYPE drop-down menu to select the type of rule you want.  Select SSH-MFA to bring up all those rules.
4. Scroll down until you locate the newly created rule, Force SSH Authentication, click the checkbox to select that rule, and then click ADD SELECTED.
5. Clicking the Add Selected button returns you to the New Policy screen where selecting the CREATE button completes the creation of the new policy.
