New Multi-Part Series: SIEM From Scratch

This year I've really jumped into the Elastic stack, rolling out dozens of small environments for personal projects and working countless undocumented evenings at my day job to profile performance, test filters and deliver the log aggregation ecosystem I'd promised my system administrators, network admins and superiors that I could deliver. I've written several posts on Logstash and Elasticsearch that were geared for folks trying to get started with the ecosystem. I hope others have found them useful and I hope they've been able to grow their environments into something that does what they need.

Every day I see more and more articles and blog posts about doing interesting things with Elastic, about deploying it as a log aggregation system, written by people who are infinitely more talented than I. They do fantastic things with the platform and I will readily admit my envy for what they are able to accomplish. My issue with those great tutorials is that they don't usually put things together in a way a true beginner can follow - they assume someone who has a specific task they want to accomplish (using various filters for enrichment, getting Windows logs into an existing stack, using the stack for DNS analysis, etc).

I am guilty of the same thing. My "getting started" tutorials assume you already have an interest in the stack and need to accomplish specific tasks. I believe this is useful and has its place; I also believe there are people who want to solve a larger problem and need a little bit of hand-holding until they're ready to start asking questions about those specific things. That's where my new multi-part series will come in.

This weekend I am starting a new set of posts that have a clear goal in mind. This is for the people who are 100% brand-new to log aggregation and SIEM, the folks who may have just made a career change (or want to make a career change) to SecOps (or Ops), the ones who have just inherited a dozen servers that all log to local files in interesting and who will benefit from aggregating those logs, the people who have just found out they're responsible for PCI compliance at their small organisation and need to start building a monitoring and alerting program with basically no budget. My goal is to give you the means to deploy a log aggregation platform that allows you to normalise log data, search logs from dozens of devices in seconds and generate alerts so you know when odd things are happening, all with the assumption that you have no prior experience in any of those areas.

This weekend I'm starting "SIEM From Scratch" and I'm pretty excited about it.
