High-velocity software development today is close to impossible (and most certainly not sustainable) without DevOps. The migration to the public cloud, along with increasing regulatory demands, and other factors made application and code security as vital as DevOps. Thus were born the practices and frameworks of DevSecOps.

The value of DevSecOps is evident and clearly understood by technologists. As many as [76%](https://www.appdynamics.com/c/dam/r/appdynamics/2023/06-resources/08-ebook/AppDynamics_Application_Security_Report-1.pdf) of technologists believe that "a DevSecOps approach is essential for organizations to effectively protect against a multi-staged security attack on the full application stack." So it's not surprising that, according to the same survey, 43% of organizations have already started implementing a DevSecOps approach in their IT departments.

But what does DevSecOps adoption actually entail for developers and DevOps engineers? And how do you employ the OWASP DevSecOps Maturity Model to measure progress in your DevSecOps strategy?

DevSecOps: Understanding the Undertaking
----------------------------------------

DevSecOps, an evolution of Development Operations (DevOps), focuses on integrating cybersecurity seamlessly with software development. This approach signifies a higher level of DevOps maturity, emphasizing the integration of security into every phase of the Software Development Life Cycle (SDLC). It involves equipping development teams to create secure code and address security issues like [common security misconfigurations](https://www.suridata.ai/blog/common-security-misconfiguration-vulnerabilities/) promptly.

Key elements of DevSecOps include automation, cross-functional teamwork, and adopting "shift left" and "continuous everything" methodologies. Successful implementation hinges on the collaboration among security, IT operations, and software development teams, aiming to embed security scanning, testing, and validation throughout the SDLC.

The DevSecOps Maturity Model Explained: What is the DSOMM?
----------------------------------------------------------

The DevSecOps Maturity Model (DSOMM) was introduced and developed by the [OWASP foundation](https://owasp.org/) to serve as a set of framework for implementing code and application security measures by using familiar DevOps principles and strategies.

There are challenges and hurdles on the way to DevSecOps maturity. These challenges include fragmented and siloed toolsets and data, as well as numerous challenges in promoting accountability and the cultural shift left throughout the organization. 

One of the reasons that the framework for integrating security into DevOps is designed as a maturity model is that maturity models are a concept that is familiar to executive management and non-technical stakeholders. As such, a maturity model presents a way to communicate the value of DevSecOps through a "story" featuring the key components of any application security initiative: people, process, and technology.

The DevSecOps Maturity Model Levels: Stage by Stage
---------------------------------------------------

The DSOMM framework consists of four levels of DevSecOps maturity. Each level represents a distinct stage in the evolution of security integration, ranging from basic awareness and ad-hoc practices to advanced, fully integrated, and automated security processes. These levels provide a roadmap for organizations to systematically enhance their security posture within the DevOps framework.

### Level 1: Basic understanding of security practices

Level 1 of the DevSecOps Maturity Model is where organizations start incorporating fundamental security practices into their development workflows. This initial stage features teams working independently with manual processes and a reactive approach to security, often addressing issues only after they arise in production.

#### Achieving Level 1 maturity involves:

-   Core Development Practices: Establishing clear build and deployment processes, with automated patching and basic threat modeling.
-   Security Awareness and Review: Communicating security objectives across the organization, providing ad-hoc security training for developers, conducting regular security code reviews, and accessing external security consultancy as needed.
-   Operational Security Measures: Implementing basic Business Continuity and Disaster Recovery (BCDR) practices, beginning application hardening efforts (reaching 50% of intended security level), enforcing source control protection, and standardizing versioning.
-   Infrastructure and Network Security: Isolating networks in virtual environments, implementing basic access controls, and using Multi-Factor Authentication (MFA) for administrator accounts. Ensuring edge encryption for data in transit and at rest.
-   Environment and [Compliance Management](https://spectralops.io/blog/7-essentials-for-cloud-compliance-success/): Keeping test and production environments separate, centralizing the logging of security events, establishing quality gates, and basic false positive detection.
-   Vulnerability and Risk Assessment: Focusing on remediation of high-severity defects, testing for exposed services, server-side vulnerabilities, and stored secrets. Prioritizing high test intensity and software composition analysis.

This level lays the essential foundation for more sophisticated DevSecOps practices, integrating security into all development and operational stages.

### Level 2: Adoption of basic security practices

In Level 2 of DSOMM, organizations begin to effectively blur the lines between security, development, and operations. This stage is marked by the adoption of standardized [DevSecOps tools](https://www.jit.io/blog/developers-guide-to-the-devsecops-toolchain), significantly automating tasks that were once manual and neglected. Remediation processes become more efficient, and the adoption of practices like Infrastructure-as-Code extends DevSecOps across entire departments.

#### Key advancements in transitioning from Level 2 to Level 3 include:

-   Enhanced Artifact Management: Focusing on building, pinning, and testing within virtual environments to ensure reliability and security of the software.
-   Software Component Tracking: Implementing Software Bill of Materials (SBOM) for comprehensive component tracking.
-   Configuration and Decommissioning: Establishing secure configuration parameters and a defined process for orderly decommissioning of systems.
-   Image and Attack Surface Management: Utilizing trusted images with regular updates and reducing the attack surface measurably.
-   Security Integration and Training: Placing a security champion in each team and conducting regular, effective security training for all relevant personnel.
-   Access and Environment Security: Enforcing Two-Factor Authentication (2FA) and hardening the application environment.
-   Data Protection and Monitoring: Ensuring internal encryption of data in transit and implementing advanced alerting and monitoring systems.

This progression signifies a deeper integration of security into the development lifecycle, enhancing the overall security posture of the organization and paving the way for more proactive security practices.
