Cyber Security – What are the Differences Between Red Teams and Blue Teams.
New entrants into cyber security often are not aware of exactly what these team designations mean, here they are in short order:
These are external people/entities that test the effectiveness of a security system or program. This is accomplished by emulating the behaviors and techniques of likely attackers in the most realistic way possible. The practice is similar, but not identical to, penetration testing, and involves the pursuit of one or more objectives.
Blue Team Leader
These are the internal security teams that defends against both real attackers and the Red Teams. Blue Teams should be distinguished from standard security teams in most organizations, as most security operations teams do not have a mentality of constant vigilance against attack, which is the mission and perspective of a true Blue Team.
These groups that exist to ensure and maximize the effectiveness of the Red and Blue teams. They do this by integrating the defensive tactics and controls from the Blue Team with the threats and vulnerabilities found by the Red Team into a single narrative that ensures the efforts of each are utilized to their maximum. When done properly, 1 + 1 will equal 3, but this should be happening naturally as the benefit of having a Red and Blue team.
The purpose of a Red Team is to find ways to improve the Blue Team, so Purple Teams should not be needed in organizations where the Red Team / Blue Team interaction is functioning properly.
