What is OWASP SAMM?

OWASP Software Assurance Maturity Model (SAMM) is a prescriptive software security framework presented by the Open Web Application Security Project or OWASP. The objective of this framework is to help organizations analyze and improve their security postures. It is an open framework that uses open-source methodologies and principles that apply to all kinds of organizations. This OWASP SAMM framework helps organizations in many ways as follows:

• It offers a strategic plan that helps organizations to improve software security.
• Evaluate the existing security measures of an organization and improve them.
• It helps create a balanced software security strategy with clearly defined iterations.
• It demonstrates measurable improvements in a security assurance program.

What are the Components of SAMM?

OWASP SAMM framework has many components that make it a reliable and practical model. It is based on 15 security practices that are divided into 5 business functions. Each of these security practices involves many types of activities that are further divided into 3 maturity levels. The following diagram shows the structure.

Let’s check out all the components of a SAMM framework in detail.

Business Functions

On top of the OWASP SAMM framework sits the Business Functions component, which defines the different activities that the organizations involved in software development must fulfill. Each of the business functions has three categories of these activities known as security practices.

The following are all the categories of the Business Functions component.

Governance

Organizations can have different approaches to managing their software development activities. Governance defines directions and practices for how they manage these activities. It has practices for cross-functional teams and business processes as its core focus.

Design

Design focuses on the processes and activities that an organization follows to create software and define its goals. Generally, this process entails software development activities like gathering requirements, specifying the high-level architecture, and creating a detailed design.

Implementation

Generally, organizations involved in software development follow various activities and processes to build and deploy software components and associated defects. The implementation function of the OWASP maturity model focuses on these processes and activities.

Activities involved in the implementation function affect developers’ routine lives the most. The shared goal of this function is to build and deploy reliable software with minimum bugs and the ability to prevent threats like SQL injection, XSS, etc.

Verification

Verification focuses on the processes and activities that an origination follows to test and check the final output produced by a software development process i.e. artifacts. It involves actions that help verify the quality of software, which we know as the quality assurance process.

This function is not limited to QA activities like testing, but it also encompasses other evaluation and review activities.

Operations

The Operations function of the OWASP SAMM model involves activities that ensure the integrity, confidentiality, and availability of software and its data throughout its life in the production environment.

It means it focuses on activities that are performed when the software is operational. A higher level of maturity in this function indicates that an organization is resilient to operational disruptions and responds to any changes in production.

Security Practices

Every business function component of SAMM involves security practices, which are a group of activities. In total, there are 15 security practices that are further divided into two streams named A and B. Each stream focuses on a different aspect of the practice with its own objectives.

Besides, these streams also create a link and align activities with different OWASP SAMM maturity levels. There are 3 maturity levels for each security practice.

The following are the security practices for different business functions:

Governance

• Strategy & Metrics
• Policy & Compliance
• Education & Guidance

Design

• Threat Assessment
• Security Requirements
• Security Architecture

Implementation

• Secure Build
• Secure Deployment
• Defect Management

Verification

• Architecture Assessment
• Requirements-driven Testing
• Security Testing

Operations

• Incident Management
• Environment Management
• Operational Management

Maturity Level

Each security practice in the SAMM model is divided into four maturity levels from 0 to 3. These maturity levels provide gradual improvement in security posture by setting goals with tangible outcomes. Let’s know about these levels.

• Level 0: At this level, there is minimal security that represents the null state.
• Level 1: Security practices are implemented as and when needed by organizations.
• Level 2: Teams define and document security practices that show noticeable improvements.
• Level 3: Teams will measure the outcomes quantitatively and continuously improve security practices.

Strengths of OWASP SAMM Model

Organizations get many advantages by adopting the Software Assurance Maturity Model. These benefits include building trust and confidence among the stakeholders and strengthening the overall defense mechanism. Let’s take a look at the key benefits of this model.

Achieve Regulatory Compliances

The SAMM model enables organizations to adhere to legal compliances and security best practices. It helps them avoid unwarranted penalties or fines due to non-compliance by protecting data as per the standards set by the legal authorities.

Protect Data and Eliminate Risks

By implementing the OWASP SAMM framework, organizations can remove the chances of security breaches. The best practices and methods described in the framework will enable organizations to build a strong and resilient security shield against cyber threats.

Address Vulnerabilities Proactively

As organizations adopt the Software Assurance Maturity Model, they can proactively address vulnerabilities. It will help organizations mitigate cyber risks in the early stages, which will eliminate the heavy costs incurred when vulnerabilities are detected later in the development process.

Tailored to Specific Organization

The SAMM framework is highly customizable, and organizations of any size, industry, or need can tailor it to their specific requirements. Hence, it is suitable for diverse businesses.

Gaining Stakeholder’s Confidence

Organizations that adopt the SAMM framework show a commitment to prioritize security. It indicates that the organizations are focusing on protecting the interests of their stakeholders. As a result, it will help build confidence among the stakeholders.

Implement OWASP Software Assurance Maturity Model in Four Easy Steps

Organizations can develop secure software and minimize the risk of cyberattacks by implementing the Software Assurance Maturity Model in the four easy steps given below.

• Perform an Evaluation: Firstly, evaluate your existing security posture to know where you stand in software security. Identify the gaps where improvements are needed to strengthen security and adopt the best practices to achieve the goal.
• Develop a Plan: The next step is to come up with the right plan to implement the framework. List the specific steps, such as defining the policies and measures to accomplish the task.
• Materialize the Plan: Implement the plan you have made. You may have to integrate news tools or methods.
• Monitor and Assess: Once the plan is in action, the job isn’t over. Constant monitoring and review of the situation are important to make sure the plan works as per your benchmark.

What are the Key Challenges in Implementing the SAMM?

While implementing SAMM provides many benefits, it’s not without its own challenges. Hence, you need to consider these challenges to effectively implement this framework and optimally secure your web apps, APIs, and other software solutions.

Internal Resistance

Implementing this framework can be challenging due to the resistance within an organization. There could be many reasons for this resistance, such as added workload, reluctance to change, and lack of understanding. Besides, the management could resist due to increased costs and disruption in existing workflows.

Effective implementation requires overcoming these challenges with proper communication of the benefits, adequate training, and other measures.

Harmony with Existing Processes

The next challenge comes from the difficulty in integrating or adjusting the new framework with the existing processes. Obviously, when new practices and methods are introduced, it will affect the ones that are established. The best way out can be to gradually introduce the changes with a detailed assessment of the impact.

Consider Scalability

When organizations expand, so do their infrastructure and ecosystem. It makes their software systems more complex and poses new kinds of security risks. Hence, organizations should choose security frameworks that scale up to this expansion. Organizations must consider the long-term scalability of the SAMM model when implementing it.

Limitation of Resources

Another challenge for organizations is resource constraints. It might be difficult for organizations to acquire the necessary tools and technologies. Besides, they also need training to effectively implement the framework, which might be hindered due to financial constraints.
