Let’s get started!

Overview of OWASP SAMM

OWASP SAMM, or the Software Assurance Maturity Model, helps organizations make their software more secure. It does this in a few key ways:

1. It provides organizations with a step-by-step plan to enhance their software security, making securing software easier to understand and implement.

2. It helps organizations identify where they need to improve their software security. This enables them to concentrate on these aspects and make real, measurable enhancements.

3. It encourages organizations to think about software security from the start of the software development process. This ensures that security is prioritized at every stage, resulting in a more secure final software product.

4. It helps to create a culture where everyone in the organization recognizes the importance of software security. This means that everyone collaborates to make the software as secure as possible.

Components of OWASP SAMM Framework

Let's take a look at the different components of the OWASP SAMM framework and how they help make software more secure. Here are the components of the OWASP SAMM framework:

1. Governance

This component focuses on establishing strategic directions and ensuring compliance with policies. It involves defining security strategies aligned with organizational goals and formulating policies for secure development practices.

2. Design

Design concerns the procedures and actions involved in how an organization establishes objectives and develops software for development projects. This process often involves gathering requirements, defining the high-level architecture, and creating a detailed design.

3. Implementation

It focuses on the processes and actions involved in how an organization develops and distributes software components and the associated errors, which are the main emphasis of implementation.

The activities of the Implementation function greatly influence developers' day-to-day lives. The shared objective is to deliver software that functions dependably, has few bugs, and is resistant to threats such as SQL injections and XSS.

4. Verification

This component ensures that security measures are accurately implemented and operational. It involves performing security testing through various techniques to identify and eliminate security flaws and conducting security reviews to ensure adherence to security policies and standards.

5. Operations

In this phase, the focus is on managing security incidents and ensuring the continuity of business operations. It involves establishing incident management procedures and planning for business continuity to ensure critical business functions can continue during disruptions.

OWASP SAMM Maturity Levels

OWASP SAMM establishes four maturity levels (0 to 3) for every security practice and business function. These levels illustrate how an organization's software security program progresses, from minimal security practices (level 0) to a well-structured and optimized state (level 3).

• Level 0 - Inactive: Organizations lack or have minimal security practices.

• Level 1 - Initial: Organizations implement security practices in an ad-hoc manner.

• Level 2 - Defined: Security practices show noticeable enhancement, and teams define and document them.

• Level 3 - Mastery: Teams quantitatively measure and continuously enhance security practices.

How to Achieve a High OWASP SAMM Maturity Level

Organizations need an all-encompassing and forward-thinking strategy to reach the top maturity level in OWASP SAMM. This strategy involves ingraining a culture of continual enhancement, integrating security into every phase of the SDLC, and using automation and advanced security methods. Follow the points for attaining the highest maturity level:

1. Cultivate a Culture of Continual Enhancement

Promote a security-focused mindset across the organization and emphasize the importance of security in all aspects of software development and implementation. Advocate for ongoing education and training, and foster transparent communication and cooperation between security teams and all departments involved in the SDLC.

2. Integrate Security Process Throughout the Entire SDLC

Use a threat modeling process to identify, analyze, and prioritize potential threats, and employ tools such as SAST or DAST to detect and address vulnerabilities before deployment. Additionally, certified ethical hackers can conduct penetration testing to reveal any remaining weaknesses, reducing false positives.

3. Leverage Advanced Security Practices and Automation

Deploy continuous integration and continuous delivery (CI/CD) pipelines with automated security checks and vulnerability scanning. Use infrastructure as code (IaC) to automate and secure infrastructure provisioning and configurations, including implementing cloud-based security solutions.

4. Continuously Observe and Enhance

Set up continuous monitoring and enhancement to detect anomalies and potential vulnerabilities in security logs, network traffic, and system behavior. Implement regular reports to provide frequent updates on software status, incidents, and assessments.

OWASP SAMM v2

On January 31, 2020, OWASP released the most recent version of SAMM, known as SAMM v2, which introduces various new features and improvements:

• Added a new business function called Implementation, encompassing essential activities in the build and deploy areas of an organization.

• Revised the maturity model to align with the latest security standards and best practices.

• Updated the SAMM Toolbox, incorporating several new tools and resources.

• The SAMM Benchmark initiative provides insights into maturity levels and progress compared to similar organizations.

Organizations of any industry and size can utilize SAMM v2. They can use it to evaluate, create, and execute a software security plan. The benefits include an enhanced software security stance, adherence to security regulations, heightened customer trust, and decreased risk of security breaches.
