Many security breaches can be detected in logs, but how do you collect together logs from all parts of your IT infrastructure, then scan for evidence? The first part of the talk will describe the architecture of the Loki project for log aggregation, based on S3-type cloud storage with no full-text index.

Then, we will look at how rules from the Sigma project can be used in Loki searches. Sigma is a platform agnostic format to define rules for compromise detection and threat hunting. All of the software described is Open Source.

Nick Moore

Nick Moore is a Senior Security Developer at Grafana Labs, where he is working to develop the next generation of Security Observability tooling. He's largely doing full-stack system development, but you may also find him providing data science expertise, and some security incident response every once in a while. His previous roles have included developing tools to help protect the UK's critical national infrastructure, providing security analysis for an autonomous vehicle project, and teaching the next generation of technologists as a cyber security lecturer for a variety of UK Universities. When he's not busy on the computer, you'll most likely find Nick running around the Cotswolds, up and down its many, many rolling hills.
