Install a Windows server CA signed certificate into ISE 2.4

Step 1: download your Root CA certificate, depending on your setup this step may vary

  • In this example my certificate authority will be my home labs windows 2008 server, it is assumed that you have access to a CA server  or signed CA certificate already

Step 2: ISE use .pem format for its certificates, the Windows CA cert is a .cer format so we are required to changed the format, to do this I  will be using Openssl as I am using a Apple MAC which comes standard if using windows you will required to download the file.

  • In Terminal or what ever application you are using go to the location of where you have stored the certificate and enter the  following command

“openssl x509 -inform der -in cacert.cer -out isecacert.pem”

Step 3: Import the signed CA cert into ISE
