DevSecOps is a methodology that integrates security into the software development lifecycle, enhancing software quality, reducing time to market, and fostering team collaboration by adopting a proactive approach to security rather than treating it as an afterthought. Originating from companies like Netflix, Etsy, and Amazon Web Services to counter cyber threats, DevSecOps emphasizes the shared responsibility among development, operations, and security teams, ensuring security is embedded at every stage of the development process. By automating security checks and leveraging continuous integration and continuous delivery (CI/CD) pipelines, organizations can identify and address vulnerabilities early, thus improving software reliability and customer trust. DevSecOps also promotes a culture of automation and ownership among developers, who are encouraged to use tools like Harness Security Testing Orchestration to prioritize application security, centralize logs, and streamline the software delivery process. With the rise of technology in business operations, adopting DevSecOps is crucial for maintaining secure, efficient, and timely software development, ultimately benefiting both the organization and its customers.
