Understanding the Software Assurance Maturity Model (SAMM)

What is SAMM?

• 💡 SAMM stands for Software Assurance Maturity Model, an open-source framework designed to guide software security strategies.
• 🎯 It is a prescriptive model that helps organizations tailor their security approach to their specific risks.

Key Features and Structure

• 🧩 The SAM framework includes 15 security practices organized into three maturity levels.
• 📊 It covers five core business functions: governance, design, implementation, verification, and operations.

SAMM vs. BSIMM

• 🔍 SAMM is prescriptive, defining what organizations should be doing for security.
• 📈 In contrast, the BSIMM (Build Security In Maturity Model) is observational, reporting what organizations are actually doing.

Evolution of SAMM

• 🚀 Originally developed by Pravir Chandra in 2009, SAM was donated to OWASP in 2016.
• ✨ OWASP released version 1.5 in 2017, improving scoring granularity and allowing partial credit.
• 🛠️ Version 2.0, released in 2020, emphasized automation and better alignment with development teams.

Benefits of Using SAMM

• 📈 A key benefit is the ability to quantify improvements in software security, moving beyond vague statements like "it's better."
• 🎯 SAMM helps define how individual security activities are performed and measured, ensuring consistent efficacy and avoiding a mere "checkbox approach."
