Summary
he primary function of a cybersecurity Green Team is to act as a bridge between the developers (Yellow Team) and the defenders (Blue Team), integrating security practices throughout the entire Software Development Life Cycle (SDLC).
Essentially, the Green Team acts as DevSecOps engineers whose primary mission is to ensure that applications are deployed securely and their entire lifecycle is fortified against threats.

Key functions of a cybersecurity Green Team include:
- Integrating Security into Development (DevSecOps): The Green Team ensures that security considerations are “baked in” from the initial design phase, rather than being added as an afterthought.
- Enhancing Detection and Response Capabilities: They work with the Blue Team to improve logging capabilities and standardize log generation, providing more useful data for improved incident response and digital forensics.
- Formulating Security Policies and Frameworks: They create policies and frameworks that guide developers (Yellow Team) and defenders (Blue Team) on secure practices for new and existing IT systems.
- Improving Communication and Collaboration: The team ensures effective communication between the builders and the defenders, facilitating a continuous feedback loop that helps both teams understand each other’s needs and limitations.
- Vulnerability Remediation: In some traditional models, the Green Team is specifically responsible for fixing the vulnerabilities and misconfigurations identified by offensive security teams (Red Team) after an engagement.
- Code-Based Defense Enhancement: They focus on enhancing the code-based and design-based defense capabilities, which may involve incorporating security testing tools into the CI/CD pipelines.
- Risk Assessment and Management: They regularly evaluate and manage security risks by having a deep understanding of the frameworks, libraries, and functionalities of the systems being developed.
