Which team focuses on defensive security?

Red Team

Blue Team

Purple Team

Green Team

Correct Answer: Blue Team

Blue Team focuses on defensive security by implementing, monitoring, and maintaining security controls to protect organizational assets from cyber threats. Blue teams serve as the primary defenders in cybersecurity operations, working continuously to detect, analyze, and respond to security incidents while strengthening overall security posture.

Blue team responsibilities encompass the full spectrum of defensive cybersecurity activities, from proactive threat hunting to incident response and recovery. These teams work to understand the organization's threat landscape and implement appropriate countermeasures to prevent, detect, and mitigate cyber attacks.

Core Blue Team activities include:

Security monitoring: Continuous surveillance of networks, systems, and applications for suspicious activity
Incident response: Rapid detection, containment, and remediation of security incidents
Threat hunting: Proactive searching for indicators of compromise and advanced threats
Vulnerability management: Identification, assessment, and remediation of security weaknesses
Security architecture: Design and implementation of defensive security controls

Blue Team tools and technologies:

Security Information and Event Management (SIEM) systems
Intrusion Detection and Prevention Systems (IDS/IPS)
Endpoint Detection and Response (EDR) platforms
Network monitoring and analysis tools
Threat intelligence platforms and feeds

Key Blue Team skills and competencies:

Log analysis and forensic investigation techniques
Network security and traffic analysis
Malware analysis and reverse engineering
Incident response procedures and coordination
Risk assessment and security control implementation

Blue teams often work in conjunction with Red teams (offensive security) in exercises designed to test and improve defensive capabilities. This collaboration, sometimes formalized as Purple teams, helps organizations develop more effective security programs by combining offensive and defensive perspectives.
