What is DevOps and how has it evolved into DevSecOps

DevSecOps represents an evolution of DevOps by integrating security into every stage of the development process to address the increasing sophistication of cyber threats. Traditional development often involved isolated teams working in sequence, leading to long cycles and limited communication, whereas DevOps introduced agile methodologies to improve speed and efficiency through tools and automation. However, security was often considered only at the end of the development cycle, which DevSecOps seeks to change by making security a shared responsibility from the beginning. This approach enhances development velocity, incorporates multiple layers of security, and promotes collaboration among development, security, and operations teams, ultimately reducing vulnerabilities and costs by catching issues earlier through automated testing. DevSecOps ensures that security is a proactive element of development, fostering innovation and accountability across teams while mitigating vulnerabilities and controlling costs.
