This listicle delivers eight key DevSecOps best practices to fortify your software development. Learn how to integrate security seamlessly into your development lifecycle, transforming it from a bottleneck to a continuous enhancement. These practices are crucial for building user trust and ensuring operational resilience. Mastering these DevSecOps best practices will help you create robust application security in 2025 and beyond. From automated security scanning to security chaos engineering, we’ll cover essential techniques to strengthen your security posture.

1. Implement Automated Security Scanning in CI/CD Pipeline

One of the most crucial DevSecOps best practices is integrating automated security scanning directly into your Continuous Integration/Continuous Delivery (CI/CD) pipeline. This “shift-left” approach embeds security checks early in the development lifecycle, transforming security from a reactive afterthought to a proactive, integral component of the development process. By catching vulnerabilities and compliance violations before they reach production, organizations can significantly reduce risks and remediation costs.

The infographic above illustrates a typical workflow for automated security scanning within a CI/CD pipeline. The process begins with the developer committing code changes. Then, various automated security scanning tools are triggered as part of the build process, including SAST for analyzing source code, DAST for testing running applications, SCA for checking dependencies, and container and IaC scanning. If a vulnerability is detected, the build fails, and the developer is notified. This immediate feedback loop ensures that security issues are addressed quickly and efficiently. The final step represents a successful build and deployment after security checks have passed. The sequential nature of this workflow highlights the importance of integrating security at each stage, preventing vulnerable code from progressing through the pipeline.

This automated approach utilizes various security scanning tools to cover different aspects of your application and infrastructure:

• SAST (Static Application Security Testing): Analyzes source code for vulnerabilities without executing the application.
• DAST (Dynamic Application Security Testing): Examines running applications for security issues, simulating real-world attacks.
• SCA (Software Composition Analysis): Scans third-party libraries and dependencies for known vulnerabilities.
• Container Scanning: Checks container images for vulnerabilities and misconfigurations.
• Infrastructure as Code (IaC) Scanning: Validates infrastructure templates for security best practices.

Why implement automated security scanning in your CI/CD pipeline?

This practice is essential for several reasons. It ensures consistent and repeatable security checks with each build, reducing human error and increasing efficiency.

By embedding security into the development lifecycle, organizations can build more secure and resilient applications.

3. Infrastructure as Code Security

Infrastructure as Code (IaC) Security is a crucial DevSecOps best practice that focuses on securing the very foundation of your applications: the infrastructure. Instead of manually configuring servers, networks, and databases, IaC defines and provisions infrastructure through code, allowing you to manage and provision your infrastructure in a safe, repeatable, and predictable manner. This approach treats infrastructure configuration as software, enabling you to scan, test, and validate for security issues before deployment, preventing insecure configurations from ever reaching production environments. This proactive approach significantly strengthens your overall security posture and is a key component of implementing DevSecOps best practices.

IaC security leverages various tools and techniques to achieve its objectives. These include pre-deployment scanning of infrastructure templates (like Terraform, CloudFormation, or Azure Resource Manager templates) for security misconfigurations, enforcing security policies for infrastructure using policy-as-code tools, and implementing drift detection to identify any unauthorized infrastructure changes that deviate from the defined code. Secure secret management for infrastructure credentials is also paramount, as is adopting immutable infrastructure patterns that minimize the attack surface by deploying fresh instances rather than patching existing ones.

This approach offers significant advantages for scrum masters, agile coaches, software development teams, and IT operations departments alike. By preventing insecure infrastructure configurations before deployment, IaC security ensures consistent security controls across all environments (development, testing, staging, and production). It enables auditability of infrastructure changes through version control, reducing manual configuration errors that could lead to security vulnerabilities. Furthermore, it facilitates compliance through codified security policies, a crucial aspect for organizations operating in regulated industries. For example, Hashicorp uses Sentinel policy-as-code to enforce security policies in Terraform configurations, while AWS’s CloudFormation Guard provides policy-based validation for CloudFormation templates. Tools like Chef InSpec further empower teams to codify infrastructure security and compliance requirements. You can learn more about Infrastructure as Code Security to see how security concerns are addressed even in specific API contexts.

While IaC security offers numerous benefits, it also presents some challenges. It requires additional tooling and expertise, and integrating legacy infrastructure can be difficult. Security policies must be continuously updated to address new threats, and it’s important to note that IaC security may not catch all runtime security issues, necessitating complementary security measures.

To successfully implement IaC security, consider these tips: implement infrastructure linting early in the development process; use pre-commit hooks to catch security issues before they enter version control; define infrastructure security baselines as code; implement least privilege principles in all infrastructure roles and permissions; and regularly audit and rotate infrastructure credentials. These practices, championed by organizations and individuals like Hashicorp (creators of Terraform), the AWS Cloud Development Kit (CDK) team, Bridgecrew (creators of Checkov, an IaC security scanner), and Kief Morris (author of ‘Infrastructure as Code’), are essential for building a robust and secure infrastructure.

By embracing IaC security as a core DevSecOps best practice, organizations can proactively address infrastructure security risks, improve compliance, and build a more secure and resilient foundation for their applications.

4. Immutable Security with Container Orchestration

Immutable Security with Container Orchestration is a crucial DevSecOps best practice that enhances the security posture of containerized applications. It combines the principles of immutable infrastructure with container security, leveraging orchestration platforms like Kubernetes to enforce strict security controls. This approach treats containers as immutable artifacts—deployed entities that are never modified after creation. Instead of patching or updating a running container, a new, updated container image is built, deployed, and replaces the old one. This eliminates the risks associated with mutable infrastructure, ensuring consistent security policies and reducing the potential attack surface.

This method fundamentally shifts how security is managed in containerized environments. By deploying only pre-approved and scanned images, organizations can minimize the risk of vulnerabilities and ensure that all running containers adhere to established security standards. Automated processes within the container orchestration platform facilitate this workflow, making security a core part of the deployment pipeline. This is a key component of DevSecOps, integrating security practices seamlessly into the development and operations lifecycle.

Features that enable Immutable Security with Container Orchestration include:

• Read-only container file systems: Preventing runtime modifications helps to maintain the integrity of the container image and reduces the risk of malware persistence.

Immutable Security with Container Orchestration is a vital DevSecOps practice for modern software development, offering a proactive and robust approach to securing containerized applications. Popularized by industry leaders like Kelsey Hightower and Liz Rice, as well as organizations like the CNCF, Docker, Inc., and the Kubernetes community, this approach provides a scalable and efficient way to manage security throughout the container lifecycle, making it an essential best practice for any organization adopting containerization.

5. Continuous Compliance as Code

Continuous Compliance as Code (CCaC) is a crucial DevSecOps best practice that shifts compliance from a periodic, manual process to an automated, continuous one. It bakes security and compliance validations directly into the development lifecycle, treating compliance requirements just like any other piece of code. This allows organizations to ensure their systems adhere to industry and regulatory standards like GDPR, HIPAA, PCI-DSS, and SOX, not just at audit time, but at all times. This proactive approach is essential for maintaining a strong security posture and avoiding costly penalties.

Instead of relying on time-consuming and potentially error-prone manual audits, CCaC codifies compliance requirements. These codified requirements are then automatically checked throughout the development and deployment pipeline, providing continuous visibility into compliance status. This allows teams to catch and remediate compliance drifts early, preventing non-compliant changes from reaching production.
