End-users are seeking modern ways to interact with IT and other shared services groups across their organization. They look for self help — where they can get secure access to apps, manage their own passwords, search for known apps or servers, request access to services that they need. IT-users need to automate tasks like account provisioning and password resets, and manage privileged access to on-premises and cloud-based infrastructure. Centrify’s identity management integrations with ServiceNow help automate processes, improve visibility, and provide a better experience for ServiceNow end-users and privileged IT-users.

 

Do you want to enable just-in-time privilege for your administration to infrastructure? Do you want to tie back the access to a valid service ticket in the workflow system of record (servicenow)?

As customers move more and more to the cloud, many customers are leveraging AWS Workspaces as a Desktop as a Service Solution (DaaS) to provide end users access to corporate resources at any time from any where.  Given Workspaces are available to anyone, from anywhere, a key consideration to moving to AWS Workspaces, is of course Security. 

 

AWS Workspaces can be configured to require Multi-Factor Authentication (MFA) to add a layer of protection to a user name and password (the first “factor”) by requiring users to enter an authentication code (the second factor), which can be provided by a virtual or hardware MFA solution.

 

There are two ways to do this.  

 

Option 1) Use Centrify Endpoint Services.  @Robertson in this article covered how to use the Centrify agent to enforce strong workspace level security with Centrify's Endpoint Services solution to deliver:

  • Access control using Centrify Zone technology
  • Strong Authentication with MFA at login, screen lockout or remote desktop
  • Privilege Elevation for application or administrative desktop

This is the most secure option.

 

Option 2) Use Centrify's MFA service with AWS Radius support to require MFA before accessing AWS Workspaces

 

In this howto, we will focus on option 2.

Multi-factor authentication (MFA) at OS login provides an extra layer of protection and helps to meet compliance for regulations such as PCI DSS 3.2, NIST 800-171, 23 NYCRR 500, and more. Centrify enables the ability to prompt for MFA at console or ssh login. This article will walk you through the steps to enable users to log into Linux and UNIX systems with Active Directory credentials and prompted for multi-factor authentication.

[How to] Force Kerberos SSH Authentication, and Disable SSH Public Key Authentication

By Centrify on ‎03-26-2018 12:31 PM - last edited ‎04-04-2018 02:18 PM

Joining Linux and UNIX machines to an Active Directory domain with Centrify Infrastructure Services has countless benefits, not the least of which is the ability to do away with SSH Public Key authentication. There are several good reasons to discontinue the use of SSH Keys. For a complete list of all of them, please reference the NIST Internal Report 7966.

 

I can save you some dry reading, and summarize it like this. If improperly managed, the use of SSH Keys can present a massive security risk. Even if every measure is taken to properly manage them, SSH key provisioning is still prone to human error, and after all, UNIX admins are only human.

Beef up your Phone-call based MFA with Centrify

By Centrify on ‎02-22-2018 07:43 PM - last edited ‎02-23-2018 11:00 AM

MFA is becoming a necessity these days and Centrify makes it easy for you to deploy “MFA Everywhere”. You can support authentication factors like phone-call, SMS, Push notification, Yubikey, FIDO U2F, Smartcards, OATH OTP, and the list goes on. For many of these authentication mechanisms, your user’s can simply leverage their own smartphone. But what if some of your users don’t have smartphones? Can you convince your CIO to purchase and manage hardware tokens? Many organizations want to get away from the overhead of managing tokens. You can see why MFA using a good old-fashioned phone call is a good option for these types of scenarios. The concept is easy, first, the user registers his/her phone number in the self-service portal. Then, at authentication time, the user confirms the receipt of a phone call to his/her mobile device by pressing the # or * key (in addition to another knowledge-based factor). There you go, 2 factors of authentication completed. But there’s a catch.
