DevSecOps is an evolution of DevOps that integrates security into the software development lifecycle (SDLC) to address increasing cybersecurity threats by involving security teams early in the development process. This approach emphasizes collaboration among development, operations, and security teams, ensuring that security measures are implemented continuously and reducing the risk of vulnerabilities. Key practices in DevSecOps include threat modeling, code analysis, and compliance monitoring, which collectively enhance software security while maintaining rapid deployment cycles.
