We covered the basics and introduction of Osquery For CyberSecurity. We went over querying Windows, MacOs and Linux SQL tables. This was part of  TryHackMe Osquery: The Basics

Оскери является Открытый исходный код agent created by Фейсбук in 2014. It converts the operating system into a relational database. It allows us to ask questions from the tables using SQL queries, like returning the list of running processes, a user account created on the host, and the process of communicating with certain suspicious domains. It is widely used by Security Analysts, Incident Responders, Threat Hunters, etc. Osquery can be installed on multiple platforms: Windows, Линукс, macOS, and FreeBSD.
