Windows Server 2012 R2 Iso Link' title='Windows Server 2012 R2 Iso Link' />While I have written a number of articles focused on SSL certificates and templates, I have not done a mini series on how to actually install a Windows Certificate Authority. For this series Im using Windows Server 2. R2, but the steps are pretty much identical for Windows Server 2. Microsoft blogs have several PKI configuration series, which directly guided the content of this series. But I always have my own spin, so I think its worthwhile to do yet anther blog post on configuring a MS CAthe Mr. SSL way. Windows Server 2. R2 Certificate Authority. The process is fairly simple Build an offline root, create an online issuing CA, setup a couple of templates, setup auto enrollment, then do a little post setup configuration. This requires two VMs, each running Windows Server 2. R2 or plain 2. 01. Building an enterprise CA is non trivial, and should be highly process oriented. While this short series will provide the steps how to configure a two tiered hierarchy, it alone is not enterprise grade and ready for a fortune 5. Many operational procedures, access controls, etc. For example, who can issue certificates Who can revoke themDo users need PKI certificates or just computers How about key recovery Disaster recoveryDo you need a hardware security module HSM Do you require FIPS compliance What ciphers and hashing algorithms will you allow Where do you store the offline CAAs you can see, there are many questions and processes that need to be well documented for a solid PKI solution. However, for a lab environment where you want to test out a two tiered model, then this short series is for you. Please dont take this solution as is and throw it into production. You will have a false sense of security and possibly do more harm than good. The Microsoft CA issues industry standard certificates x. For instance, they will work perfectly fine on the Linux v. Center appliance, or your hardware load balancers. You just need to use the proper certificate template, and verify compatible algorithms. Offline Root CA Hardening. Provision a standalone Windows Server 2. R2 server. I used v. Center 5. 5 with customization specifications to create the VM. You can use the standard edition of the OS since all SKUs in 2. R2 and earlier. For security purposes I would not provision a NIC, or remove the NIC after youve built the CA to prevent future network attacks. Configure a virtual floppy for the offline CA VM. This is a good way to transfer data between the offline CA and the subordinate, which is required during the configuration process. Yes you could connect a NIC, but then your offline CA is no longer offline and exposed to network attacks. Media needs to be readwrite, so an ISO image will not suffice. You can use a tool like Win. Image to create a floppy image. Open the local security policy and modify the Audit Object Access to record Success and Failures. This is needed to audit certain CA actions, in conjunction with a CA flag we will set later on. Depending on your VM template hardening, you may or may not need to modify the password policy. Again in the Local Security editor. Modify to meet your organizations security requirements. You should also rename the Administrator account, if thats not already built into your templates. Make sure to record the new name, or you could be in a pickle. For good measure Id rename the guest account, although it should be disabled. Obviously you should change the administrator password and not use your template default. Be sure to record the password in a secure location. You should also think about where you will store the offline CA VM once it is build and this project is complete. Windows Live Essential 2011 Offline Installer on this page. If you leave it sitting on a production ESXi host, then it would be fairly trivial to power on the VM and compromise it. I would not call storing your offline CA in a powered off state on a production ESXi host offline. I would look at exporting the VM to an OVF file, then storing that file on removable media in a very secure location. You could use a DVD, Blu Ray, or USB stick. Install Offline Root CA1. After your VM is provisioned and hardened, make sure the computer name is configured. In my case the offline CA is name D0. CA0. 1. Reboot if you changed the name. Use Notepad and create a file called CAPolicy. C Windows. Use the code snippet below, but change the URL. This URL is where your Certification Practice Statement CPS is located. It will also be where the CRL certificate revocation list will be published. For a production deployment youd want to create a CPS, but for this exercise we will skip it, however the URL will be configured for future usage. For additional details see this Tech. Net link. You probably want to use a different URL like CA. PKI. yourdomain since we will be publishing other data to this address such as the CRL. For simplicity I stuck with www.

This name will be present in all issued certificates, so make it obvious what it is and not just some generic hostname that is not meaningful. Notice that we are using SHA2.

Run the following commands, using the appropriate URL for your organization. We arent using HTTPS here, because that requires SSL and certificate validation. This is just used to download the CPS and CRLs, so dont get clever and use HTTPS here. We will configure SSL for the web enrollment module, though. Get CACrl. Distribution.
