DevSecOps vs Agile: Navigating the Crossroads of Security and Agility

What are the DevSecOps and Agile Cultures?

Both Agile and DevSecOps cultures emphasize collaboration, communication, and continuous improvement driving efficiency, productivity, and overall success. These cultures function in an environment where teams in the US work together, learn, and adapt to changes and security considerations. Let’s understand both DevSecOps and Agile culture in detail;

🔸 DevSecOps Culture

DevSecOps culture involves thinking and working that incorporates security into the development process and lifecycle. The collaborative methodology combines developers, security experts, and operation engineers to develop secure and faster software.

DevSecOps culture follows three key principles and they are;

1. Security is everyone’s responsibility
2. Security should be automated
3. Security must be continuously practiced

As security is integrated throughout the process, DevSecOps culture helps identify and mitigate security issues in the early development or deployment process. The automated security checks help in reducing and eliminating vulnerabilities that speed up the delivery of the software. Incorporating DevSecOps culture can help you ensure quality development and improved user experience.

🔸 Agile Culture

The agile culture emphasizes flexibility, collaboration, and continuous improvement in the development lifecycle. The culture encourages organizations to adapt to changes and deliver the best results by breaking down each functionality and making it more manageable and working iteratively.

Agile culture works on three key principles as follows;

1. Focus on the users
2. Empower teams and encourage collaboration
3. Continuous improvement

Agile culture helps in developing products and services that focus on users’ needs and demands which can lead to customer satisfaction and loyalty. Agile methodologies foster a culture of making decisions and taking ownership of the work and creating a sense of accountability in the development process. It also encourages continuous feedback which helps in improving the product and services which fits into users’ demands and needs.

DevSecOps or Agile: Which One to Choose?

When it comes to the software development lifecycle, the two approaches DevSecOps and agile have helped businesses enhance collaboration and acceleration of software delivery. Still, they have different focuses and can be used in different situations. Let’s explore some types of projects or organizations that can benefit from each methodology;

🔹 Projects with a High Focus on Security

Organizations dealing with highly sensitive data, regulatory compliance, or operating in highly regulated industries, such as healthcare or finance, can benefit from the DevSecOps approach. The incorporation of security practices ensures a proactive approach toward security and compliance in the development process.

🔹 Complex Systems

DevSecOps is a suitable approach for projects that involves interacting systems with multiple interconnected components. The approach involves continuous monitoring and collaboration between development, security, and operations teams to help address security concerns and maintain system integrity.

🔹 Projects with Iteration and Continuous Feedback

The Scrum methodology helps projects with responsiveness and adaptability to change requirements which improves quality and faster developments. Startups, software development consultancies, or projects with evolving customer demands can implement Agile methodologies to deliver value faster and iteratively.

🔹 Innovation-Driven Projects

Agile allows teams to experiment, innovate and learn from the feedback loops. Agile believes in a collaborative and transparent approach where innovation and exploration are encouraged. Organizations emphasizing innovation such as tech startups or research and development teams can leverage Agile’s iterative approach.

DevSecOps and Agile: Using Together

The two approaches, DevSecOps and Agile can complement each other when integrated efficiently. While DevSecOps emphasizes security and continuous monitoring, Agile focuses on iterative development and continuous faster delivery. When integrated, these methodologies develop an effective framework that promotes collaboration, responsiveness, and security throughout the software development lifecycle.

💡 Security-first Agile

By leveraging DevSecOps with Agile, security is integrated from the start of the development process. The security concerns are incorporated into each iteration, reducing the risk of vulnerabilities and enabling faster response to issues and changes with a combined approach of DevSecOps and Agile.

💡 Continuous Feedback

The agile approach promotes continuous feedback loops with customers and stakeholders. When combined with DevSecOps, the feedback loops can include security concerns, allowing stakeholders to provide feedback on security vulnerabilities, threat models, and risk assessments. The combined approach can help in aligning security measures with user experience.

💡 Early Identification and Mitigation of Security Issues

DevSecOps and Agile can help in the early identification and mitigation of security vulnerabilities. Continuous security monitoring, testing, scanning, and code analysis throughout the iteration can help teams to identify and address security issues promptly, reducing risks of breaches.

💡 Cross-functional Collaboration

DevSecOps encourages collaboration between development, security, and operations teams. Agile methodologies also encourage cross-functional collaboration among team members. By combining both approaches, organizations can encourage a culture of shared responsibility and collaboration, enabling teams to work together efficiently and address security concerns effectively.

💡 Automation in the Security

The agile approach embraces automation practices for development and testing. DevSecOps extends this automation to security testing by integrating tools and techniques that perform automated vulnerability scanning, static code analysis, and dynamic application security testing (DAST). The security testing within the Agile framework, organizations can identify and address the issues early in the development process.

Choosing Between Agile and Devsecops: 4 Factors

The choice between DevSecOps and Agile depends on the specific requirements and priorities of your organization. We have listed some of the factors that can help you choose between DevSecOps and Agile;

▶️ Security Requirements

If the organization operates with highly sensitive data and a regulated industry, security is the main concern. DevSecOps should be a priority for the development of the software. The security practices and compliance makes DevSecOps the preferred choice for the development process.

▶️ Development Speed vs. Security

Agile methodologies are a preferred approach for organizations that demand faster software development. The agile approach also helps organizations to adapt to ever-evolving customer requirements. However, if the organizations also want to focus on security in development with an emphasis on speed, DevSecOps can be a preferred approach.

▶️ Organization Culture

With the current organizational culture, DevSecOps culture needs a major cultural shift and collaboration needs across teams. If the organization is already practicing DevOps culture and has major security concerns, you can always apply DevSecOps culture in the organization.

▶️ Project Complexity

As agile methodology helps in navigating the changes and requirements, it is considered to be an effective one for complex projects and smaller teams. While DevSecOps can provide the necessary framework to ensure security is incorporated into the development of the software.
