Requirements road sign

I’ve been an engineer for a long time. In order to solve problems, my customer gives me requirements so that I can provide solutions. But the process breaks when the customer shortcuts the requirements process.

One More Time About Time

Time Zones

I’ve written about the importance of having accurate time before, and have always said that it can be difficult to keep a proper clock. I’ve always looked at it from a technical standpoint but a couple of days ago, one of my students sent me a video
and it caused me to look at the topic of time from a completely different perspective.

New Adventures

Today I am excited to announce that I have a new job! After spending the last year and a half or so at SEE, I’ve decided to make the move to SealingTech. While I love the team at SEE, SealingTech offered me a new adventure.

Workstation Setup

Dev Ops

I’ve been doing dev work for years but have never taken the time to document how I like my setup which means every time I do it again, I have to figure it all out again.

Implementing SSLSplit

A couple of weeks ago I talked about using SSLSplit to at as a proxy so that I could examine the mechanics of a Docker pull. I decided to go ahead a set up a purpose-built VM just for this so I could easily do this again in the future. I wanted to go ahead and document (and share) the steps that I went through for this.

Retirement Calculator 2022 Edition

It occurred to me earlier today that I have done a poor job of keeping it current, so I decided to spend a few minutes and get it fully updated (I think) for 2022.

Retirement….One Year Later

Retired Vet

Today marks one year since my last day wearing the uniform. Sure, my official retirement date wasn’t until Sept, but a lot of things have happened. In that time, we’ve continued to live through a pandemic, I’ve started a job, quit a job, and started another one, done a lot of work around the house, and been able to enjoy life a little bit.

Unique Identifiers of a Fresh Kali Image

Kali Linux

The act of attributing a cyber attack is a long sought after, but rarely attained goal. While things such as techniques, IP addresses, and other artifacts can plan an important role in attributing an attack, being able to attribute actions to a specific computer that has been obtained can help provide overwhelming proof of an act. In this post, I’m publishing a paper that I started working on a few months ago (life gets busy) that provides a forensic analysis of multiple freshly installed Kali systems. My goal over the coming months is to conduct similar experiments on other operating systems. I’ve also provided the raw data that I used to conduct my analysis.
