This guide details the implementation of a robust, ransomware-resilient backup architecture following the extended 3-2-1-1-0 rule. It covers critical steps such as classifying assets, defining RPO/RTO, implementing immutable or air-gapped storage, and isolating backup credentials from the production domain. Use this knowledge to design a multilayered defense against data loss and ensure reliable recovery points.

This guide details the architecture and implementation of a ransomware-resilient backup strategy, adhering to the extended 3-2-1-1-0 methodology. It covers critical steps including defining RPO/RTO, establishing immutable/air-gapped copies, isolating backup credentials from the production domain, and automating periodic restore testing. Use this framework to ensure business continuity against sophisticated cyberattacks.

Chainsaw is a fast, Rust-based tool for digital forensics and threat hunting. It enables analysts to rapidly perform Sigma rule checks and keyword searches across collected Windows Event Logs (.evtx) and specialized artifacts (like shimcache and SRUM). Ideal for first-response and offline analysis, it provides detection capabilities without needing a SIEM ingestion pipeline, allowing quick hypothesis testing in the field or air-gapped environments.
