This is the personal blog of Zachary Burnham – a DFIR Consultant at RSM within their Security and Privacy Risk Consulting team.

As Zach was developing skills regarding DFIR, Cybersecurity, and SOC at college, he realized he needed a better way to organize his notes on the wealth of subjects he was being exposed to. Furthermore, he didn’t have a clear way to share this knowledge, or a way to help his peers who may have had some of the same questions he had.

The purpose of Burnham Forensics is to solve that problem – to not only be a place for him to come back to for notes, but for others to peruse who are interested in the same topics discussed here. As a sort of “public notebook,” he is hopeful that this blog can be utilized to help those in his field and others similar.

I recently learned about Distributed File Systems (DFS) and the benefits they could bring to an organization whose needs require redundant and highly available information across their systems. As part of a class project, I had to look into MooseFS, a fault-tolerant, network based DFS that can be mounted to virtual disks on client machines. … Continue reading MooseFS: Build and Installation Guide

Creating a Multi-Node ELK Stack

Previously I had written a guide on Creating a Single-Node ELK Stack; covering what to do when you want create and utilize The Elastic Stack (also formally ELK) on a limited capacity, single-node basis.
