What Is A Red Team?

A red team consists of security professionals who act as adversaries to overcome cyber security controls. Red teams often consist of independent ethical hackers who evaluate system security in an objective manner.

They utilize all the available techniques (discussed below) to find weaknesses in people, processes, and technology to gain unauthorized access to assets. As a result of these simulated attacks, red teams make recommendations and plans on how to strengthen an organization’s security posture.

What Is A Blue Team?

A blue team consists of security professionals who have an inside out view of the organization. Their task is to protect the organization’s critical assets against any kind of threat.

They are well aware of the business objectives and the organization’s security strategy. Therefore, their task is to strengthen the castle walls so no intruder can compromise the defenses.

What Is A Purple Team?

A purple team isn’t necessarily a stand alone team, although it could be. The goal of a purple team is to bring both red and blue teams together while encouraging them to work as a team to share insights and create a strong feedback loop.

Management should ensure that the red and blue teams work together and keep each other informed. Enhanced cooperation between both teams through proper resource sharing, reporting and knowledge share is essential for the continual improvement of the security program.
