Deployment

integration of security practices into the deployment pipeline within the broader context of DevOps. DevOps, which combines development and operations, emphasizes collaboration, automation, and continuous delivery to achieve faster and more reliable software development and deployment. DevSecOps extends this philosophy by incorporating security principles throughout the entire development and deployment lifecycle.
