In an article that I wrote last week for CSOonline, I described the use of a red team framework from Mitre called ATT&CK. in my post this week, I compare four free open source tools that leverage this framework and how they can be deployed to help expose your network vulnerabilities. The four tools are:

• Endgame’s Red Team Automation (RTA),
• Mitre’s own Caldera,
• Red Canary’s Atomic Red, and
• Uber’s Metta

Each have their good and bad points. You can read my review here.
