Cyber Security Operation Team
-
Red TeamItem Link List Item 1
The Red Team is an offensive security group that acts like real-world attackers. Their main job is to simulate cyberattacks against an organization to find vulnerabilities before actual malicious hackers do. Red Team members think creatively like adversaries — they might attempt phishing, penetration testing, privilege escalation, and exploiting unpatched systems. They operate covertly, meaning the rest of the organization often doesn't know when a Red Team operation is taking place. The goal is not just to break into systems, but to test how well the defenses work, how fast teams detect threats, and how incidents are handled. Their findings are later shared to strengthen the organization’s security posture.
-
Blue TeamItem Link List Item 2
The Blue Team is responsible for defensive cybersecurity operations. Their job is to protect, monitor, and respond to threats against systems and networks. Blue Teams build layered security, conduct risk assessments, monitor system logs, detect intrusions, and neutralize attacks in real time. They use tools like firewalls, SIEM (Security Information and Event Management) systems, endpoint protection, and network monitoring to keep an organization secure. While Red Teams simulate attacks, Blue Teams focus on identifying and stopping them as fast as possible. They also improve resilience by patching vulnerabilities, training staff, and developing incident response plans to minimize damage from real attacks.
-
Purple TeamItem Link List Item 3
The Purple Team acts as a bridge between the Red and Blue Teams. Instead of working separately, the Purple Team promotes collaboration between offensive and defensive efforts to maximize security effectiveness. Their role is to ensure that Red Team findings directly help the Blue Team improve defenses. Likewise, the Purple Team helps the Red Team understand evolving defensive strategies to craft better simulations. They often orchestrate exercises where attacks and defenses are tested side-by-side, sharing real-time feedback. In organizations without a dedicated Purple Team, it can also refer to a philosophy where Red and Blue Teams work closely together instead of staying isolated. The ultimate goal of a Purple Team is to create a faster learning cycle between attacking and defending.
-
Yellow TeamItem Link
The Yellow Team focuses on building and developing systems with security in mind from the start. They are often the software developers and engineers who work on creating secure applications, writing secure code, and integrating cybersecurity best practices into product development. Their job is to minimize vulnerabilities before a system even goes live.
-
Orange TeamItem Link
The Orange Team is a blend of Red and Yellow teams. Their focus is to help developers (Yellow) learn from attackers (Red). They actively bridge offensive security knowledge into the software development cycle, teaching secure coding practices and threat modeling to prevent issues that Red Teams might otherwise exploit.
-
Green TeamItem Link
The Green Team is a combination of Blue and Yellow. They focus on working with developers to ensure that systems are both secure (Blue) and correctly built (Yellow). They encourage writing defensive code, building secure infrastructure, and developing security-by-design principles.
-
White TeamItem Link
The White Team plays a governance and oversight role, particularly during cybersecurity exercises like Capture the Flag (CTF) competitions or red vs blue simulations. They set the rules of engagement, monitor activities to ensure fairness, make sure no real damage occurs, and judge performance. In a broader organizational sense, they ensure compliance, ethical standards, and documentation of cybersecurity practices.
-
Black Team (rare)Item Link
In large-scale security exercises, a Black Team may refer to those who design and secretly control the testing environment, setting up hidden challenges, vulnerabilities, and traps that both Red and Blue teams must discover and react to.
