Microsoft SDL and OWASP SAMM Mapping: A Comprehensive Analysis

Microsoft SDL and OWASP SAMM Mapping: A Comprehensive Analysis

Introduction

The Microsoft Security Development Lifecycle (SDL) was introduced in 2004 as Microsoft’s response to the security challenges that plagued its Windows operating system. As the first formal secure SDLC framework, it laid the foundation for many secure software development practices.

Today in its latest version, Microsoft SDL comprises 10 security practices, each containing a set of requirements designed to reduce security risks across the software development lifecycle. While Microsoft does not specify terminology, we refer to these as “requirements.” In total, there are 49 requirements across SDL’s 10 practices.

Building Security In Maturity Model (BSIMM) Mapped to OWASP SAMM

Introduction

The Building Security In Maturity Model (BSIMM) and OWASP Software Assurance Maturity Model (SAMM) share a common history. Both were conceived around 2008-2009 and are based on OpenSAMM, which was created by Pravir Chandra. Over time, however, these two models have evolved independently, with distinct conceptual differences. We have previously explored these differences in detail . Despite their divergence, both frameworks aim to help organizations enhance their application security programs. Recognizing this shared mission, we have developed a detailed mapping between SAMM and BSIMM, highlighting their similarities and points of alignment.
