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.

SAMM Scoring: Percentage to Target and Percent to Date Metrics

SAMM Scoring: Percentage to Target and Percent to Date Metrics Introduction: the “not applicable” answer A common question among SAMM users is whether specific activities, streams, or entire practices can be marked as not applicable. This seems reasonable—some security activities might not fit an organization’s current reality. For example, the Supplier Security stream focuses on supply-chain risks in outsourced development. If your organization doesn’t outsource, it might seem irrelevant. The SAMM core team acknowledges this, but emphasizes future readiness.

Building Security In Maturity Model (BSIMM) Mapped to OWASP SAMM The full mapping sheet between BSIMM 14 and 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 .

OWASP SAMM now connects to OpenCRE

By The SAMM Project Team in assessment

September 20, 2023

We are excited to announce that each OWASP-SAMM stream now uses OpenCRE.org to link to other standards and guidelines. OpenCRE stands for Open Common Requirement Enumeration, and it aims to provide a common language and framework for mapping and comparing different security standards, guidelines, and frameworks. By linking SAMM to OpenCRE, we’ve made it easier for our users to find relevant and useful resources with every stream, as well as to see how SAMM aligns with other security standards such as NIST SSDF, ISO27K, PCI-DSS, OWASP ASVS, and NIST 800-53.

Determining scope when implementing SAMM

May 24, 2023

When performing a SAMM assessment, should the scope be the whole organization or should it be smaller, like a business unit or even a single team or application? The short answer? Start small. Getting started Start by evaluating your goals. What do you want to achieve? Do you aim to identify and prioritize areas of improvement in your organization’s security posture? Do you seek to establish a baseline for measuring the effectiveness of your security program over time?

How ISO and SAMM complement each other

March 21, 2023

October 2022 brought us the third revision of the ISO/IEC 27001 standard. The revisions included simplifying the domains and controls, using more practical language, and introducing new controls. The addition of a separate control for “Secure Coding.” provides an opportunity to highlight how OWASP SAMM and ISO 27001 are complementary standards. In this blog post, we shine light on how they intersect and how, implemented together, you can maximize their effectiveness and value.

The "Not Applicable" Question

By The SAMM Project Team in assessment

February 28, 2023

The Core Team’s Thoughts Since the initial publication of SAMM 2.0, several SAMM users have asked how to address Activities or Quality Criteria they believe are not applicable to their assessment’s scope. At the recent SAMM Core Team Summit in Boston, we discussed this question at some length, and this article summarizes that conversation. The topic really involves several questions, which we’ll address one at a time. Is it valid to declare an Activity Not Applicable?

Tackling App Security with SAMM-NIST SSDF Mapping

February 6, 2023

The Application Security Challenge The increasing dependence on software in our daily lives has made the challenge of ensuring its security more pressing. Despite being a critical concern, cybersecurity is often not a priority for organizations until there is an incident or breach. This has resulted in the cost of cyber insurance doubling in the past two years and the total cost of cybercrime in 2022 reaching $7 trillion .

Introducing SAMM Practitioners

By The SAMM Project Team in community

December 5, 2022

Why SAMM Practitioners? We want to adopt OWASP SAMM 2.0 at my workplace. Can you recommend a company to help us do this? SAMM team members get asked this a lot through the different channels of communication like our Slack channel and the contact form on the website. Obviously, we know many companies, organizations, and individuals who can do this. We are a community-driven project and a number of volunteers have contributed to SAMM so it wasn’t an easy answer for us to provide.

Addressing Log4J vulnerabilities with SAMM

By The SAMM Project Team in guidance

February 7, 2022

It’s that dreaded notification. The one that holds the threat, and later the reality, of many sleepless nights. The newest vulnerability is here and its severity is considered critical. This Log4J vulnerability (CVE-2021-44228) has caused quite the stir, and rightfully so. It’s kept security peeps on our toes for the last few months so it was interesting to see this topic come up during our last SAMM monthly community call.
