Traditional Pentesting (Red Team) is adversarial. They sneak in, drop a report "You have vuln X", and leave. The Blue Team (Defenders) often feel attacked and can't reproduce the findings. Purple Teaming bridges this gap.
How it works
- Red Team says: "I will execute T1059.001 (PowerShell) at 10:00 AM."
- Blue Team watches the SIEM at 10:00 AM.
- Result: Did the alert trigger?
- Yes: Good job. Can we make it faster?
- No: Why? Is the rule broken? Let's fix it right now.
- Repeat.
1. Benefits
1. Real-time Feedback: No waiting 2 weeks for a report.
2. Training: Blue team learns HOW attacks work. Red team learns protecting mechanisms.
3. ROI: You prove that your million-dollar EDR tool actually works (or doesn't).
2. Atomic Red Team
You don't need a human hacker for every test.
Atomic Red Team is an open-source library of simple scripts that simulate malicious behavior.
Run `atomics/T1003.001.yaml` to dump LSASS. See if your antivirus screams.
3. The Mindset Shift
The goal is not "Winning". The goal is "Improvement".
If the Red Team gets caught, it's a victory for the organization.
If the Blue Team misses it, it's a learning opportunity, not a failure.
Breach & Attack Simulation (BAS)
Automated Purple Teaming tools (like Cymulate, SafeBreach) allow you to run thousands of attacks continuously, ensuring your security posture doesn't degrade over time.
