In cybersecurity, a red team is a group of security professionals who act as adversaries to overcome cybersecurity controls. They simulate attacks against a blue team, which is a group of defensive security professionals responsible for maintaining internal network defenses against all cyber attacks and threats. The goal of red teaming is to test the effectiveness of an organizations cybersecurity measures and identify vulnerabilities in their system. Red teams use a variety of methods and tools to exploit weaknesses and vulnerabilities in a network, including penetration testing, social engineering, and malware infection. Once they gain initial access, they elevate their privileges and move laterally across systems with the goal of progressing as deeply as possible into the network, exfiltrating data while avoiding detection. Red teams make recommendations and plans on how to strengthen an organizations security posture based on their findings. Red teams are used in several fields, including cybersecurity, airport security, law enforcement, the military, and intelligence agencies.
