Which statement best describes blue team role in cyber workforce?

• A. Defends networks and interprets alerts.
• B. Simulates adversaries to test defenses.
• C. Coordinates red and blue activities during exercises.
• D. Primarily performs external penetration testing.

Answer: (A)

Blue team work centers on defense: protecting networks, monitoring for threats, and quickly detecting and responding to incidents. In practice this means defending systems and networks and interpreting alerts from security tools like SIEM, IDS/IPS, and endpoint protection so analysts can triage, investigate, contain, and recover from incidents. This defensive focus is what defines the blue team. The other descriptions describe offensive or coordination activities outside the blue team’s primary duties: simulating adversaries to test defenses is red-team work, aimed at finding and exploiting weaknesses; coordinating red and blue activities during exercises is typically a purple-team or exercise-control role focused on improving collaboration; and external penetration testing is also a red-team activity. Therefore, the statement that best fits the blue team is defending networks and interpreting alerts.
