How do I set up access to CORE / Zscaler?

Body

Overview

CORE is the State of Colorado Resource Engine. It functions as a data warehouse for the State of Colorado and has several different purposes. Some teams at MSU Denver such as Accounting Services or Finance may need to access this engine to upload institutional data to the state. In order to access the engine, a proxy connection must be set up on your University computer using Zscaler. This guide is only intended to document the portions or the process that involve MSU Denver ITS.

Before you begin...

Access to this service is highly restricted. You must obtain prior authorization from the State of Colorado CORE Office. Please work with your supervisor to obtain this access before continuing. See Additional Resources for state contact information.
As of 2/17/2023, the directions to connect have been updated. Previous directions instructed users to use Internet Explorer. It involved several steps to add URLs to the Trusted Sites Zone, set up proxy connections in Internet Explorer, etc. These directions are no longer relevant. The service can be accessed using simple machine-wide proxy settings and using any modern browser including Chrome, Firefox and Microsoft Edge. Please be aware that there are many PDF guides circulating that contain these old directions.

Instructions

Request access from the State of Colorado. Work with your supervisor to do this. MSU Denver ITS has no visibility on these systems.
Once you have received your log in credentials, identify the certificate needed to connect. This file may be provided to you through communications from the state or it may be available in your department's network drive. Multiple people can use the same certificate. It usually expires every year.
