This workshop (DevSecOpsRO 2023) aims at attracting innovative, high-quality research on secure software development (DevSecOps) practices. Security is not a feature that should be considered and added at the end of the software production cycle, but, on the contrary, it must be an integral part of all steps along the software supply chain. Accounting for security comes with significant challenges, especially considering the time constraints imposed by agile development. With this workshop, we aim at attracting significant contributions that will foster the adoption of robust, novel techniques in developing software that is secure by design. Papers must be submitted through the EasyChair system. All information will be available soon.
