DevSecOps is a fusion of development, security, and operations that implements security practices from inception to ensure a secure, agile, and efficient software delivery process. It differs from traditional DevOps by prioritizing security right from the beginning in mobile app creation. DevSecOps embeds security measures early into every stage of the DevOps lifecycle using automation, ensuring faster vulnerability patching, container and microservice security, CI/CD process security, data security, DevOps tool security, code security, and shift-left testing. To implement DevSecOps, teams need to adopt a cultural shift that breaks down silos between development, security, IT, and operations, cultivate a security-focused mindset, and choose the right security testing methods such as static application security testing, dynamic application security testing, and interactive application security. Platforms like Bitrise play an instrumental role in DevSecOps for mobile developer teams by offering tools and automation necessary for seamless integration of security practices, enabling faster, safer, and more efficient delivery of software.
