Managing secrets in Continuous Integration (CI) and Continuous Deployment (CD) workflows is critical due to the potential security vulnerabilities that can arise when these secrets are not handled properly, such as API keys, passwords, and certificates. A centralized secrets management solution with encryption at rest and in transit, access control mechanisms, and audit logs is essential for securely storing and managing secrets. Integration with CI/CD tools and automation of secrets rotation minimize the risk associated with compromised secrets, while applying least privilege access ensures that only necessary services and team members have access to specific secrets. Regularly auditing and monitoring secret access helps detect unauthorized access or anomalies, and leveraging a robust secrets management solution like Doppler can simplify and strengthen the security of CI/CD pipelines, empowering teams to focus on delivering high-quality software securely and efficiently.
