The US-CERT (Computer Emergency Response Team) recently gave a presentation on what China has been doing to hack anything they can hack with the goal of stealing intellectual property, money and personally identifiable information. While most public sector schools and government agencies are generally not vast repositories of intellectual property, they do manage and transfer […]
We constantly harp on all of you segregating third-party vendor equipment on to vendor VLANs. The purpose of that is to keep third-party vendor equipment completely away from your internal network. Ideally, we don’t want these vendors to see, touch, or ask your internal network anything.
We continue our discussion of your closets and dumb stuff that can really hurt you. In part III we look at “plan b” and “plan c” for what to do if the power goes out for both the physical and virtual servers as well as your MDFs. If you put a physical server in any […]

The February Tech Talk Webinar is SCCM Troubleshooting Part II. Scott will introduce the new Support Center for client troubleshooting which became available in 1810. It provides real-time log viewing, or capturing the state of a Configuration Manager client computer for later analysis.

As 2018 comes to a close, on behalf of everyone at CSI I would like to say thank you for entrusting us with your technology needs. Unlike most of our competitors we solely service K-12 and Public Sector. We take your network very seriously. We take what happens to it personally.
