Microsoft identity lifecycle manager ILM
My story of Microsoft multi factor authentication
In this blog post, I will be talking about Microsoft multi factor authentication, and more specifically, their smart card Management solution, and how you can manage the life-cycle of smart cards, from enrolling them, managing them and finally retiring smart cards. The product that I will be taking about is called Microsoft identity lifecycle manager ILM.
When I start working in the security field back in 2007, security was a very complicated and dark field to me. I started working on security baselines and firewalls, before realizing so quickly that no matter how hard you secure your environment, bad guys will always get you.
I quickly understand that a security administrator shall do everything he can to protect his assets, but also assume breach. The next layer of protection is multi-factor authentication. In 2007, multi-factor authentication comes in form of smart cards or security tokens. I was so interested in smart cards, because you can integrate your badge and access control with your smart card. One card for all purposes. Sound interesting.
Microsoft identity lifecycle manager ILM & Smart Cards
So, I start doing calls with Gemalto, one of the big smart card providers. I was so excited to work on smart cards, and I quickly realized that smart cards come with a complicated and sophisticated management overhead.
Why is smart card management being so difficult? Well, you need to issue smart cards, by issuing a certificate from your CA to that piece of hardware. Smart cards get stolen, and you should be able to revoke certificates on that smart card. What if certificates got expired on the smart cards? In that case, you may need to replace certificates on the smart card and consider leaving the encryption certificate there, so that people can still decrypt encrypted files.
I looked for many management solutions out there, and I decided to try Microsoft identity lifecycle manager ILM. Of course, at that time, I already had Microsoft certificate services server installed with offline root CA. I had to deploy this new ILM server to start managing smart cards.
Microsoft Smart Card Management Guide
I worked very hard in 2007 to deploy Microsoft identity lifecycle manager ILM server, and I want to share my experience in a small guide. This guide can help you even if you are using the new Microsoft FIM/ CM server, as it demonstrates the different possible operations that can be made to a smart card, and what each operation do to the certificates inside the smart card.
The guide Index:
- Certificate Templates.
