Purple Teaming Whitepaper
The red team / blue team concept in cyber security has its roots in the military. Wargaming exercises, between attacking (red teams) and defending (blue teams), helps assess attack readiness and defence strength. The teams gain practical experience and post exercise reviews provide knowledge to improve real event ‘readiness’. The cyber security world mirrors this; the attacking red team are mainly external penetration testers and the defending blue team are normally internal security and technical teams.
