It’s 2017 – Stop Guesstimating!

I’ve been involved in a number of planning meetings for IT infrastructure refreshes – servers, storage, WAN, networking, wireless, you name it. Most of the time the requirements are more or less well-defined and well thought out… number of hosts, exact processors, memory requirements, connectivity to the storage arrays, VLAN assignments, and so on. All […]

General Blogspam

Sorry it’s been so quiet over here lately. I’ve been engaged in several new projects that are taking up the majority of my time. I don’t have anything to share with you today that I’VE created… but I have something better! Something that OTHER people have created! Here’s a few articles and videos from around […]

This is done through an EAP exchange over the 802.1X framework. We’ve touched on this briefly in a post about RBAC, but I wanted to take some time to review two of […]

Understanding Wireless Encryption

Wireless is great because it gives you mobility – you can get your work done just about anywhere these days (which is both a good and a bad thing)! But there is an inherent drawback to mobility as wireless traffic is unbounded. It flows in all directions and eavesdropping on private conversations is both easy […]

Role Based Access Control

You’re only as strong as your weakest link. This old adage is especially true when it comes to network security. You can purchase the most expensive, ridiculously feature-rich firewall on the market, install it at the WAN edge, and think that you are safe. But without internal network controls in place as well, you run […]
