Which team is responsible for defending the company's infrastructure according to the security division structure?

The blue team is fundamentally responsible for defending the company's infrastructure within the context of a security division structure. This team plays a crucial role in ensuring the safety of an organization’s systems and data by implementing measures that protect against potential threats and attacks.

Members of the blue team focus on proactive defense strategies, which include monitoring networks for suspicious activity, responding to incidents, conducting risk assessments, and developing security policies and procedures. Their goal is to create a robust defense that mitigates vulnerabilities and minimizes the impact of any breaches that occur. This proactive stance is essential for maintaining the integrity, confidentiality, and availability of the organization’s information assets.

In contrast, other teams, such as the red team, are often tasked with simulating attacks to test defenses, while the purple team typically serves as a bridge between red and blue teams to enhance collaboration and communication. The green team, though less commonly referenced, may focus on improving the overall security posture through development and automation of security practices. Understanding the roles of these teams highlights the importance of the blue team’s responsibility in defending infrastructure against real-world threats.
