The Future Web: Privacy or Security (You Only Get One)

Matt Schmitz/ September 4, 2018

With the release of Android 9.0 recently, Google enabled a big change for how user’s can protect their privacy: DNS over TLS. While the concept isn’t brand new, it also hasn’t exactly exploded in usage either. This is going to start changing as Google rolls out the new version of their operating system that not only comes with the feature,

Thoughts on Cisco’s 2018 Annual CyberSecurity Report

Matt Schmitz/ February 21, 2018

When I started in networking, I never would have thought that security would be such an important part of my job. However, it has become something that I’m involved with almost every day – tasks like applying security configurations, participating in audits, or spending a day chasing down the latest vulnerabilities. It’s already become second nature to watch for what’s

What is Risk Acceptance?

Matt Schmitz/ February 14, 2018

You can’t always get what you want. As an engineer though, it’s your job to determine what’s best for the company and recommend it to management. What happens if your suggestion gets turned down?

Matt Schmitz/ December 5, 2017

Earlier this year I was involved in a string of interviews for an open network engineer position. The questions and scenarios provided during the interviews were aimed for someone mid-level.

Over this past weekend I purchased a few upgrades to my home network/lab. One of which was upgrading my older Ubiquiti 802.11n wireless access point to the newer 802.11ac model they have out.

A while back I wrote some basic information on how to get started implementing multi-homed internet using BGP.

Port Security: Worth the effort?

Matt Schmitz/ March 14, 2017

Port Security. Always seems like one of those things covered in Cisco exams, yet how many businesses actually use it? For those that aren’t implementing it, should they? Or is it too much of a headache? So the concept of port security is fairly simple – We want to secure each individual switch port to a physical layer 2 MAC

The Argument for Standardized Configurations

Matt Schmitz/ January 31, 2017

There are quite a few things that you don’t realize how great they are until you don’t have them anymore. For me, one of those things was standard guidelines for device configurations. At my last job, documented standards were extremely important – we had them for everything. While some devices might ultimately be configured in a slightly different manner to accommodate
