8 Steps to Secure-By-Design Software Development

The evolving threat landscape and growing regulatory expectations are pushing organizations to adopt a proactive approach to software security. At a recent security conference in Boston, I outlined eight actionable steps that companies can take to embed security into their software development lifecycle. Here’s a concise guide to get you started.

1. Select and Document a Secure SDLC Framework

Start by adopting a secure software development lifecycle (SDLC) framework, such as NIST SSDF, SLSA, or CISA’s Secure by Design principles. Documenting your conformance ensures a structured approach to security while helping meet global regulations like EU DORA and others.

2. Move Beyond Scanning & Patching

Traditional vulnerability scanning isn’t enough. Organizations need to implement adaptable measures to address evolving software supply chain threats, focusing on proactive prevention rather than reactive fixes. AI and automation can play a pivotal role here, reducing detection and response times while saving costs—up to $1.88 million per breach on average.(Ref- https://www.ibm.com/reports/data-breach)

3. Use Open Source Responsibly

Given the prevalence of open-source software (96% of codebases use it), teams must implement robust dependency scanning and vulnerability management to minimize risks from third-party code. Responsible use of open-source software is foundational to secure supply chains.

4. Provide Secure Defaults for Developers

Secure configurations should be the default, not an afterthought. Simplifying security for developers reduces toolchain complexity and ensures security measures are integrated seamlessly into workflows. Organizations with secure defaults empower developers to focus on innovation rather than battling friction.

5. Foster Security Awareness Among Developers

Up-skill developers with AI-driven tools, real-time security feedback, and vulnerability resolution guidance. A workforce trained in security best practices is critical for long-term resilience. Solutions like GitLab’s Advanced SAST enable developers to identify, prioritize, and resolve vulnerabilities directly within their workflows, minimizing disruption and fostering trust with security teams.

6. Enhance Pipeline Visibility

CI/CD pipelines often lack transparency, making it hard to detect anomalies. Implement monitoring and flagging mechanisms to provide actionable insights without overwhelming teams with data. Aim for deeper understanding, not just more data, to empower proactive decision-making.

7. Strengthen Identity & Access Management (IAM)

Focus on foundational IAM practices, including secrets management, the principle of least privilege, and robust identity lifecycle management. These measures are crucial for safeguarding sensitive systems and ensuring only authorized access.

8. Publish Software Bills of Materials (SBOMs)

SBOMs provide visibility into the components of your software, enabling better tracking and management of vulnerabilities. Start small and iterate to improve coverage and utility over time. Their adoption is still in its infancy, but they are essential for securing complex systems.

Adopting secure-by-design principles is about more than just compliance; it’s about turning challenges into opportunities. These steps can help enable organizations to innovate faster, scale securely, and build stronger customer trust. Executives also play a crucial role in this transformation. By embracing transparency, accountability, and a culture of security from the top down, leaders can create an environment where security is seamlessly integrated into the development process.
