Once in technical training, it was surprising to see how unstable and insecure the systems were (these were government systems, right?). Months later, at my first duty station, a role in Joint Expeditionary Force Experiment 2000 was my assignment. This Experiment was to test new ways to adapt to changing conditions in the battlespace, which included red/blue infosec teams trying to ward each other off. We hit a problem with some new network gear and the monitoring system we were using. We knew attacks were imminent. There were many interfaces across the network that we couldn't monitor because our monitoring system required additional licenses to monitor SNMP devices. Enter open source software: I ran an idea I had up my chain of command. My mentor and I went off and grabbed a handful of parts off an equipment self. We built a modest Red Hat Linux server. I spent a week carrying around a book titled, 'Unix Hints and Hacks' much to the chagrin of senior leadership.

That would allow us to see anomalies graphed in real-time and react to them accordingly. Attacks did come, we were able to see an influx of activity at the network boundary and begin the work to thwart it while paying closer attention to internal systems for signs of compromise. The experiment ended in great success. Since we had created the only place in the Air Force that could monitor this new gear, my work center inherited directly from the vendor a bleeding-edge VoIP system for us to tinker with before it went for testing in early 2001. 6 6 7 -Within a few days, we had used [[nmap>>url:https://nmap.org/]],[[MRTG>>url:https://oss.oetiker.ch/mrtg/]], [[Apache httpd>>url:http://httpd.apache.org/]], and a handful of other open source tools to better lock down the network and build a network monitoring and utilization dashboard system.

In the ten years since being medically separated, I've embraced many open source projects. Two open source projects (and the communities around them) have completely changed my life; Ansible and Kubernetes. So much so, that I made it a point of contributing back to both ecosystems through personal and work time. That work time went from as allowed by an employer to my full-time job when I joined Red Hat in 2018 on the Ansible team. 10 10 11 11 There I worked as a product marketer with an extreme fondness for the Ansible community that had helped me so much technically. After a year of doing Ansible work while continuing to work in [[Kubernetes' SIG Contributor Experience>>url:https://github.com/kubernetes/community/tree/master/sig-contributor-experience]], I joined the OpenShift team and now spend my day working on and volunteering with Kubernetes and its beautiful community. I am currently helping build out the [[Kubernetes Upstream Marketing Team>>url:https://github.com/kubernetes/community/tree/master/communication/marketing-team]] while being on staff for KubeCon Contributor Summits and New Contributor workshops. The volunteer role as a [[CNCF Ambassador>>url:https://www.cncf.io/people/ambassadors/]] has given me the tools to help people onboard in the community faster and I'm very grateful for it.
