A blue team is a group of professionals responsible for network defense within an organization. They use various security measures to prevent, detect, and respond to intrusions, malicious activities, and other cyberthreats. The blue team monitors network traffic to detect threats, implements protective measures such as firewalls and intrusion prevention systems, and performs vulnerability scans to detect weaknesses. They also maintain a system of active logs and records that can be used for investigation and forensics when an attack is detected. The blue team also educates users on best security practices and trains staff on security processes and technologies. The goal of the blue team is to keep the network and IT infrastructure safe from attack and compromise, constantly monitor the system for threats, and respond quickly and appropriately if an attack is detected.
