Awesome Cybersecurity Blue Team

A collection of awesome resources, tool, and other shiny things for cybersecurity blue teams.

Cybersecurity blue teams are groups of individuals who identify security flaws in information technology systems, verify the effectiveness of security measures, and monitor the systems to ensure that implemented defensive measures remain effective in the future. For offensive TTPs, please see awesome-pentest.
