PKI Certificate Verification Management Pack
Posted by rburri on September, 2 2009
PKI certificates are used to provide SSL encryption for web sites, to secure cross-server traffic (for example to join security gateways or agents in untrusted domains on OpsMgr), to guarantee the identity of the sender of a message and so on. What all certificates have in common is that their destiny often means to be forgotten after having been requested and installed. Until a certificate becomes invalid that was vital to a service. Mostly because it has expired.
To avoid service interruptions or embarrassment due to SSL warning messages displayed to users, the PKI Certificate Verification Management Pack was born. It discovers certificates and certificate revocation lists stored locally on computers and alerts you when:
– a certificate’s lifetime is about to expire (by default 21 days in advance)
– a certificate’s lifetime has ended
– a certificate has become invalid because of a different reason
– a CRL has not been updated in a timely manner
The MP also includes a series of inventory reports, which help keeping up with all those certificates in your environment. You will find more details in the comprehensive MP guide.

I wrote the MP in close collaboration with Pete Zerger and Jaime Correia of the SCC community. Without their help and the support of everyone testing the MP, it wouldn’t be here today.

And there’s more! For everyone interested in learning how to author MPs: Have a look at the 6 part series MP Creation Zen. The articles will walk you through the process of writing an MP, carefully clarifying everything you need to know. Whenever possible, all authoring examples are explained using the new and much improved OpsMgr 2007 R2 Authoring Console, telling you how the PKI Certificate Verification MP was written. I recommend the documents to everyone planning to write a Management Pack by themselves without being application developers.
