Just can't get enough of IT

This blog is about mostly anything in IT. But the primary focuses are Microsoft Technologies like Exchange, Office 365, Azure and Cloud Security.

When you run software solutions that make use of TLS secured communication channels the applications need to have access to the certificate's private key. The private key is part of the certificate stored in the local certificate store of the computer. In most cases the software solution creates a new self-signed certificate and configures access rights appropriately.

When establishing TLS communication channels to external partners, the use of a public SSL/TLS certificate is a must have requirement.

The following step-by-step instructions describe how to assign Read permisson for the Email Security Solution Gateway NoSpamProxy. In this case the solution does not utilize a classic service account, but a so-called virtual service account. Virtual service accounts provide a much better access security when executing Windows services.
