DevSecOps, short for development, security, and operations, is an approach that emphasizes culture, automation, and platform design, ensuring security is a collective responsibility throughout the entire IT lifecycle.

What is DevOps?

DevOps revolves around three pillars: organizational culture, process, and technology/tools. These pillars aim to facilitate collaborative work between development and IT operations teams, enabling them to create, test, and release software more swiftly, agilely, and iteratively compared to conventional development processes.

The evolution of DevSecOps is a response to the imperative of consistently integrating security throughout the Software Development Life Cycle (SDLC). This ensures that DevOps teams can deliver secure applications with speed and quality.

By integrating testing, triage, and risk mitigation earlier in the Continuous Integration/Continuous Deployment (CI/CD) workflow, it prevents the time-consuming and often expensive consequences of addressing issues postproduction.

This concept aligns with “shifting left,” moving security testing towards developers. This empowers them to address security issues in their code almost in real time, rather than adding security as an afterthought at the end of the SDLC.

DevSecOps spans the entire SDLC, covering planning, design, coding, building, testing, and release, incorporating real-time continuous feedback loops and insights.

As per The DevOps Handbook, the DevOps ideal involves providing developers with rapid, continuous feedback on their work. This empowers them to swiftly and autonomously implement, integrate, and validate their code, leading to its deployment into the production environment. In simpler terms, DevOps aims to eliminate barriers between traditionally separated teams.

In a DevOps model, development and operations teams collaborate seamlessly throughout the entire software application life cycle, encompassing development, testing, deployment, and operations.

What is DevSecOps?

DevSecOps is an abbreviation for development, security, and operations, and it serves as an extension of the DevOps methodology. Each component delineates distinct roles and responsibilities within software teams engaged in the development of software applications.

Development: It involves the comprehensive process of planning, coding, building, and testing the application.

Security: Integrating security measures at an earlier stage in the software development cycle. For instance, programmers ensure the code is devoid of security vulnerabilities, and security practitioners conduct additional testing before the software is released by the company.

Operations: These are the activities of releasing, monitoring, and resolving any issues that may arise from the software.

Why is DevSecOps so important?

DevSecOps strives to assist development teams in efficiently managing security concerns. It represents a contemporary alternative to outdated software security practices that struggled to adapt to tighter deadlines and swift software updates.

To appreciate the importance of DevSecOps, let’s take a brief look at the software development process.

Software development lifecycle

The software development lifecycle (SDLC) is a systematic process that directs software teams in creating top-notch applications. Utilizing the SDLC, software teams aim to cut costs, mitigate errors, and guarantee that the software consistently aligns with the project’s objectives.
The software development lifecycle navigates software teams through several key stages:

1. Requirement analysis
2. Planning
3. Architectural design
4. Software development
5. Testing
6. Deployment

DevSecOps in the SDLC

In traditional software development approaches, security testing operated independently from the Software Development Lifecycle (SDLC). Security flaws were typically identified by the security team after the software had been built.

The DevSecOps framework enhances the SDLC by proactively identifying vulnerabilities throughout the entire software development and delivery process. This integration ensures a more comprehensive and continuous approach to security, preventing the discovery of flaws only after the software has been constructed.

The functioning of DevSecOps involves a standard workflow:

1. Software Development: The software is developed using a version control system.
2. Code Analysis: Another team member scrutinizes the application for security weaknesses, evaluates overall code quality, and identifies potential bugs.
3. Secure Deployment: The application is deployed with security configurations in place.
4. Automation Testing: Automation is employed to test various aspects of the application, including its back end, user interface, integrations, and security features.
5. Testing Approval: If the application successfully passes the automated tests, it proceeds to the production environment.
6. Production Monitoring: In the production environment, multiple monitoring applications and security software continuously oversee and safeguard the application.

Implementing DevSecOps poses several challenges:

1. People and Culture Shift:

   – Retraining Teams: There is a need to retrain individuals within DevOps teams to comprehend security best practices and effectively operate new security tools.

   – Cultural Adoption: Teams must adopt the mindset that they bear responsibility not only for the features, function, and usability of the software but also for its security throughout the development and deployment phases.
2. Tooling Integration:

   – Selecting and Integrating Tools: Finding the right security tools and seamlessly integrating them into the DevOps workflow is a significant challenge.

   – Automation and Integration: The degree of automation in DevSecOps tooling and its integration with Continuous Integration/Continuous Deployment (CI/CD) pipelines directly impacts the level of training and cultural adaptation required.
3. Adapting to Modern Environments:

   – Open Source Challenges: As modern software applications heavily rely on open source software (around 70%), traditional security tools may struggle to accurately detect vulnerabilities in this context.

   – Containerized Environments: Traditional security tools, even those labeled as “cloud security,” may not effectively assess the risks associated with applications running in dynamic containerized environments, where instances can rapidly spin up and down.

Navigating these challenges involves not only technological adjustments but also a substantial focus on training, cultural transformation, and aligning security practices with the evolving landscape of software development.

What is DevSecOps in Agile development?

In agile development, DevSecOps represents the integration of security practices into the iterative cycles of the agile framework.

Agile Development:

-Agile Mindset: Agile is a mindset fostering efficiency and adaptability within software teams as they build applications and respond to changes.
