The Basics of DevSecOps: Building Security into DevOps Culture

Discover how DevSecOps integrates security into the software development lifecycle for safer, faster delivery.

As businesses embrace faster software delivery cycles to remain competitive, DevOps security has emerged as the preferred approach for rapid development and operations collaboration. However, the increasing pace of development often leaves traditional security methods struggling to keep up, leading to potential vulnerabilities. This is where DevSecOps steps in — a model that integrates security seamlessly throughout the software development lifecycle (SDLC).

DevSecOps removes these silos, bringing together developers, operations staff, and security team members at each phase.

This article delves into the new and refined methods of DevSecOps implementation and breaks down some obstacles to DevOps security.

The Need for DevSecOps

As digital landscapes evolve, traditional methods like manual code reviews, periodic security audits, and perimeter defenses can’t keep pace with the demands for robust, continuous security.

DevSecOps emerges as a solution to these challenges, integrating security directly into the DevOps workflow, ensuring security isn’t an afterthought but an integral part of the entire development cycle.

DevOps Vs. DevSecOps

Incorporating DevSecOps isn’t just about security; it’s about building resilience and trust within fast-moving development cycles.

Key Industry Statistics

• The global DevOps market is anticipated to experience substantial growth, with its value estimated to rise from USD 10.4 billion in 2023 to USD 25.5 billion by 2028. According to research by Global Newswire, the market is expected to expand at a compound annual growth rate (CAGR) of 18.95%, reaching USD 12.2 billion by 2026.
• According to a report by IBM Security, the average cost of data breaches increased from USD 3.86 million in 2020 to USD 4.24 million in 2021, an increase of USD 0.38 million (USD 380,000), representing a 9.8% increase.

These stats underline the growing need for DevSecOps, as traditional security approaches are no longer sufficient in today’s fast-paced development environments.

So, how can businesses start adopting DevSecOps to address these crucial needs? Let’s explore the specifics in detail.

How to Adopt a DevSecOps Model?

Transitioning to a DevSecOps model ensures that security is an integrated part of the development process, fostering a more proactive approach to identifying and resolving security issues.

1. Cross-Functional Collaboration for Security Integration

The objective of DevSecOps is cross-functional collaboration involving the development and operations teams. The concept is that security should be directly integrated into the SDLC instead of having a separate phase. This avoids security as a relic of afterthought and catches vulnerabilities much earlier.

Before exploring how DevSecOps reshapes security practices, it’s helpful to compare it to traditional methods to understand why this model is gaining traction. While old practices cause a delay due to security, DevSecOps is flexible and provides an integrated solution.

The “shift-left” strategy encourages security teams to actively participate in planning and designing the software, reducing delays during final code reviews.

2. Promoting a Culture of Shared Security Responsibility

A shared responsibility model is critical for DevSecOps’ success. In this model, security becomes part of the development and operations teams’ objectives. Everyone is accountable for ensuring that security practices are followed throughout the pipeline.

This approach cultivates a culture where security is not limited to one team but is embedded throughout every phase of the development process, resulting in more secure and resilient software.

Integrating security into every development phase requires a shift in mindset and approach. Educating and collaborative efforts between security and development teams are essential to nurturing a secure environment.

3. Educating and Collaborating Between Security and Development Teams

One of the challenges in traditional security approaches is the disconnect between developers and security experts. Organizations can close this gap by educating and training development teams on secure coding practices.

Collaborative security reviews, code audits, and hands-on workshops between the development and security teams promote a culture of mutual learning and help identify potential security flaws early in the cycle.

Policy and Governance

Aligning DevOps security with organizational policies creates a cohesive framework for ensuring compliance with industry regulations and promoting security best practices across all teams and departments.

1. Ensuring DevOps Security Aligns with Overall Organizational Policies

DevOps security practices should align with the company’s overall security policies, including data protection regulations like GDPR or HIPAA. For instance, if your organization handles sensitive customer data, you’ll need to ensure that security protocols meet the standards set forth by these regulations.

The governance framework should include regular audits to ensure teams consistently apply security policies across the development and operations landscape.

2. Importance of Security Policies and Governance

To ensure the policies do not break through industry regulations and best practices, the DevOps processes provide clear security policies that ensure standard access control, encryption, secure coding, and disaster recovery procedures.

3. Alignment of Teams on Security Procedures

Security governance ensures that all teams are aligned on critical security procedures:

• Access Control: Defining who is authorized to access infrastructure and sensitive data.
• Configuration Management: Ensuring that all systems are properly and securely configured involves setting up and maintaining system settings that minimize vulnerabilities and maximize security.
• Code Reviews: Instituting a review process that includes security checks before any code is merged into the production environment.

Automation in security processes can make a difference in further streamlining security.
