Which cybersecurity role defends the network after a Red Team engagement?

• A. Blue Team
• B. Red Team
• C. White Hat
• D. Security Analyst

Answer: (A)

The main idea here is who is responsible for defending the network when an attacker is simulated to test defenses. A Red Team imitates real attackers, probing detection, response, and resilience to see where defenses fail. After that exercise, the defenders who monitor for threats, detect and respond to incidents, and implement fixes are the Blue Team. They handle ongoing security operations, triage alerts, contain breaches, eradicate threats, and apply lessons learned from the engagement to strengthen controls and detection capabilities. While a White Hat is an ethical tester and a Security Analyst can be part of defensive work, the role focused on defending the network after a Red Team engagement—carrying out continuous monitoring, incident response, and improvement—belongs to the Blue Team.
