Which team is primarily focused on offensive security measures within an organization?

The correct choice highlights the role of the Red team, which is specifically focused on offensive security measures within an organization. The primary objective of the Red team is to simulate attacks against the organization to identify vulnerabilities and weaknesses in its security posture. This team employs various techniques, including penetration testing and social engineering, to mimic the tactics of real-world attackers. Their goal is to provide the organization with insights on how to fortify its defenses and improve overall security awareness.

In contrast, Blue teams concentrate on defensive security measures, working to protect the organization from attacks and manage incidents. A Green team, while it may have a role in training or collaboration between Red and Blue teams, is not typically recognized in traditional cybersecurity frameworks as a distinct entity focused solely on offensive measures. The Yellow team typically refers to roles involved in compliance and governance. Thus, the function and purpose of the Red team are distinct and clearly aligned with offensive security, making it the correct answer.
