The Microsoft SDL introduces security and privacy considerations throughout all phases of the development process, helping developers build highly secure software, address security compliance requirements, and reduce development costs. The guidance, best practices, tools, and processes in the Microsoft SDL are practices we use internally to build more secure products and services. Since first shared in 2008, we’ve updated the practices as a result of our growing experience with new scenarios, like the cloud, Internet of Things (IoT), and artificial intelligence (AI).
