Crossing the other side of the bridge

Yesterday was the last day of the quarter. Naturally, it makes for a good day to reflect on the past three months. I mentioned in my last post that something new was on the horizon, and I’m now excited to share it. ORD -> SFO On March 1, 2019, I had my first one way flight booked from Chicago to San Francisco. I never actually thought I’d move further away from my friends and family. Today actually marks my first official month living in the city.

Last month, I attended SecTor 2014 in Toronto, a beautiful city in Ontario, Canada. Actually, that was the first time I had ever attended the conference and visited the country. I had a great time, and I met a few people that really made the rest of my time out there worthwhile.

Mcafee second-hand device research project

Earlier this year, I was invited to join a group of smart students from DePaul University to conduct some research on the risks associated with buying and selling used electronic equipment. Our research team received over fifty different second-hand devices that were purchased and provided by McAfee, part of Intel Security. For a short video and key findings, please visit the original blog post that was published by McAfee earlier last month. ...
