Introduction Logging and traffic monitoring are of utmost importance in information security. Having searchable stored logs can allow visibility into a variety of critical activities related to a data breach. For example, individual computer event logs can provide insight into an attacker’s lateral movement within an environment. Active Directory authentication logs can provide more detail into this lateral movement and even help to establish a timeline of this movement. Firewall logs can provide insight into an attacker’s first contact or the first time an attacker utilized a particular command or control domain. NetFlow logs allow visibility into how a user interacts with other devices internally. ...

Introduction When I initially began posting publicly on this site, my goal was to be able to host my site fully with Docker for containerization. I hadn’t experienced any other decent blogging platform besides WordPress at the time, and I was bent on getting WordPress self-hosted with Docker. This goal was achieved, and my first public post details how I used docker-compose to deploy my blog using containers for WordPress and Traefik. ...

This post will show you how to run Tails OS as a VM with the Persistence feature enabled. Running Tails as a VM is not recommended generally as it defeats many of the security features in Tails. For example, virtualization requires that you trust the hypervisor host, as the hypervisor has extra privileges over a VM that can reduce security and privacy of the VM. I recommend reading Tails’s official documentation about virtualization considerations before continuing: https://tails.boum.org/doc/advanced_topics/virtualization/ ...

If you game on PC, you probably have Discord installed to chat with your friends as you game. Discord has relatively decent audio, and it far surpasses the in-game chat capabilities built into most games.

This post will show you how to configure a setup to forward audio from an Xbox party directly to Discord, and visa versa. This way, you can game with your Xbox friends and still use the far superior Discord. ...

Introduction Recently, I had the opportunity to collaborate with a university research lab to build some vapor sensors to roughly measure ethanol (EtOH) vapor within an operant chamber. This project was a lot of fun. With extremely limited circuit documentation on the web and never having personally used Arduino before, there were a lot of interesting hiccups I ran into. Overall, this project was a bit out of my wheelhouse, but with much determination, the finished product turned out rather nicely. ...
