CI/CD Security Guide

Implementing Open Source Security Tooling into your CI/CD Pipeline

Securing your Continuous Integration and Continuous Deployment (CI/CD) pipeline is no longer optional—it’s essential. This guide is your go-to resource for building, implementing, and optimizing secure CI/CD workflows. Whether you’re a developer, DevOps engineer, or security professional, we provide information on the open-source tools and guidance you need to model security at every stage of your pipeline. From securing code and builds to monitoring post-deployment environments, our hub empowers teams to integrate security seamlessly into their workflows without sacrificing speed or agility. Explore, learn, and transform your CI/CD processes into a fortress of innovation and resilience.

Why this Guide

This guide helps DevOps engineers build security-compliant CI/CD pipelines by mapping new open-source automation tools to evolving security frameworks. As security standards evolve, pipeline updates are essential to ensure safer software development. This guide explores the intersection of security tooling and the CI/CD pipeline, identifying key security practices, tools, and strategies that align with accepted frameworks such as the Secure Software Development Framework and the NIST Cybersecurity Framework. This guide aligns framework-defined tasks with open-source tools to accomplish them.

This CI/CD Cybersecurity Guide has been segmented into three 3 major chapters:

  • CI/CD Code and Prebuild - this section includes security tooling for the earliest points in the CI/CD workflow.
  • CI/CD Build and Deploy - this section covers security tooling for both the build step and deployment step, regardless of where the deployment is occurring (test or production).
  • CI/CD Post Deploy - security does not stop after the binaries have been deployed. This section covers continuous vulnerability management and Dynamic Application Security Testing (DAST).

For more information on Security Frameworks or Public Security Policy, visit the OpenSSF Public Policy or EU Cybersecurity Resilience Act pages.

You can also learn about the OpenSSF Open Source Manifesto to help along the journey.

Compliance Goals

Compliance Policies and Practices are being defined across both public and private sectors. Specifically, the US Executive Order (EO) on Improving the Nation’s Cybersecurity and the EU Cyber Resilience Act (CRA) aim to define how to manage threats and vulnerabilities by establishing standardized frameworks for cybersecurity requirements. These frameworks cover the complete software development process, from design through ongoing monitoring of production software assets.

The inclusion of security tooling in the Continuous Integration and Continuous Deployment (CI/CD) pipeline is one crucial area where policy and practices can be implemented and automated. With the rapid pace of development and deployment in modern DevOps environments, security must be seamlessly embedded into each phase of the pipeline to protect applications and data from vulnerabilities and attacks.This is the new job of the DevOps team. This guide is intended to help the DevOps teams easily navigate the new frameworks and understand the tooling needed to achieve the stated compliance goals.

1 - Phase 1: Code and Prebuild

Security Compliance for Code and Prebuild

Introduction

Integrating security into every stage of the Software Development Life Cycle (SDLC) is more critical than ever. The code and prebuild stage is foundational to creating secure, reliable, and high-performing applications. Failing to address vulnerabilities early can lead to costly fixes, data breaches, and reputational damage down the line.

This section provides a comprehensive guide to the essential security tools that developers and DevOps teams should use during the code and prebuild phase to ensure vulnerabilities are identified and mitigated before they can cause harm. From Static Application Security Testing (SAST) to dependency scanning and secure CI/CD pipelines, the right tools can help you adopt a proactive approach to software security while maintaining development velocity. Following are guidelines from industry frameworks with suggested open source tooling needed to achieve the compliance goals.

1.1 - Secure Software Development Framework

Secure Software Development Framework and Code/Prebuild CI/CD Steps

Achieving Code and Prebuild Tasks of the Secure Software Development Framework

The Secure Software Development Framework, developed by the National Institute of Standards and Technology (NIST), provides a comprehensive approach to ensuring security across the software development process, from initial design through deployment and maintenance. The framework outlines key practices and guidelines that organizations can implement to secure their software development lifecycle (SDLC), with a particular emphasis on integrating security into automated processes. This chapter focuses specifically on DevSecOps tooling and practices related to Code and Prebuild actions of the CI/CD pipeline to achieve:

Prepare the Organization (PO) Organizations should ensure that their people, processes, and technology are prepared to perform secure software development at the organization level. Many organizations will find some PO practices to also be applicable to subsets of their software development, like individual development groups or projects.
Protect the Software (PS) Organizations should protect all components of their software from tampering and unauthorized access.
Produce Well-Secured Software (PW) Organizations should produce well-secured software with minimal security vulnerabilities in its releases.
Respond to Vulnerabilities (RV) Organizations should identify residual vulnerabilities in their software releases and respond appropriately to address those vulnerabilities and prevent similar ones from occurring in the future.

2 - Phase 2: Build and Deploy

Security Compliance for Build and Deploy

Introduction

As software moves from development to production, the build and deploy stages play a pivotal role in maintaining the integrity, security, and provenance of your application. These phases involve compiling, packaging, and preparing your application for its live environment, making them prime targets for supply chain attacks, unauthorized modifications, and hidden vulnerabilities.

Integrating security into these phases ensures that your code is not only functional but also safeguarded against threats. From dynamic analysis during builds to automated scans for container security and misconfigurations, the right tools can help identify risks before deployment. Moreover, secure deployment pipelines prevent unauthorized changes, enforce compliance, and enable safe rollouts. Compliance for Build and Deploy steps include:

Reproducible and Deterministic Builds Ensure that software artifacts can be independently verified and reproduced to prevent tampering.
Automated Threat Detection and Compliance Enforcement Integrate continuous security analysis to detect misconfigurations, vulnerabilities, and unauthorized dependencies before deployment.
Policy-Enforced Deployments Enforce verifiable security policies ensuring only compliant, attested software reaches production.
Trusted Execution Environments (TEEs) Secure build environments against tampering using hardware-backed execution environments.
Cryptographic Attestation Use digital signatures and cryptographic proofs to verify the authenticity and integrity of builds and deployments.

Following are guidelines from industry frameworks with suggested open source tooling needed to achieve the compliance goals.

2.1 - Secure Software Development Framework

Secure Software Development Framework and Build/Deploy CI/CD Steps

Achieving Build and Deploy Tasks of the Secure Software Development Framework

The Secure Software Development Framework, developed by the National Institute of Standards and Technology (NIST), provides a comprehensive approach to ensuring security across the software development process, from initial design through deployment and maintenance. The framework outlines key practices and guidelines that organizations can implement to secure their software development lifecycle (SDLC), with a particular emphasis on integrating security into automated processes. This chapter focuses specifically on DevSecOps tooling and practices related to Build and Deploy actions of the CI/CD pipeline to achieve:

Prepare the Organization (PO) Organizations should ensure that their people, processes, and technology are prepared to perform secure software development at the organization level. Many organizations will find some PO practices to also be applicable to subsets of their software development, like individual development groups or projects.
Protect the Software (PS) Organizations should protect all components of their software from tampering and unauthorized access.
Produce Well-Secured Software (PW) Organizations should produce well-secured software with minimal security vulnerabilities in its releases.
Respond to Vulnerabilities (RV) Organizations should identify residual vulnerabilities in their software releases and respond appropriately to address those vulnerabilities and prevent similar ones from occurring in the future.

2.1.1 - Protect the Organization (PO)

3 - Phase 3: Post Deploy

Security Compliance for Post Deployment

Introduction

The post-deploy stage of your software delivery pipeline is where your application is live and actively serving users. While much of the focus in DevSecOps is on securing code, builds, and deployments, ensuring robust security doesn’t end there. The post-deploy phase is critical for monitoring, maintaining, and adapting to new threats in real time. This phase includes tools and practices for continuous monitoring, vulnerability patch management, and incident response. From runtime application self-protection (RASP) to real-time threat detection and log analysis, post-deploy security ensures your application remains secure, compliant, and reliable in production.

Industry Frameworks

Following are guidelines from industry frameworks with suggested open source tooling needed to achieve the compliance goals.

3.1 - Secure Software Development Framework

Secure Software Development Framework Post Build CI/CD Steps

Achieving Post Deploy Tasks of the Secure Software Development Framework

The Secure Software Development Framework, developed by the National Institute of Standards and Technology (NIST), provides a comprehensive approach to ensuring security across the software development process, from initial design through deployment and maintenance. The framework outlines key practices and guidelines that organizations can implement to secure their software development lifecycle (SDLC), with a particular emphasis on integrating security into automated processes. This chapter focuses specifically on DevSecOps tooling and practices related to Post Deploy actions of the CI/CD pipeline to achieve:

Prepare the Organization (PO) Organizations should ensure that their people, processes, and technology are prepared to perform secure software development at the organization level. Many organizations will find some PO practices to also be applicable to subsets of their software development, like individual development groups or projects.
Protect the Software (PS) Organizations should protect all components of their software from tampering and unauthorized access.
Produce Well-Secured Software (PW) Organizations should produce well-secured software with minimal security vulnerabilities in its releases.
Respond to Vulnerabilities (RV) Organizations should identify residual vulnerabilities in their software releases and respond appropriately to address those vulnerabilities and prevent similar ones from occurring in the future.

3.1.1 - Protect the Organization (PO)

Protect the Organization (PO) Post Deployment CI/CD Steps

Protect the Organization (PO)

Organizations should ensure that their people, processes, and technology are prepared to perform secure software development at the organization level. Many organizations will find some PO practices to also be applicable to subsets of their software development, like individual development groups or projects.


PO.1 Define Security Requirements for Software Development: Ensure that security requirements for software development are known at all times so that they can be taken into account throughout the SDLC and duplication of effort can be minimized because the requirements information can be collected once and shared. This includes requirements from internal sources (e.g., the organization’s policies, business objectives, and risk management strategy) and external sources (e.g., applicable laws and regulations).


To satisfy SSDF PO.1 in a post-deployment context using open-source tools, the focus shifts from just defining to:

Produce Well-Secured Software (PW) in the Post-Deployment CI/CD Steps

Produce Well-Secured Software (PW)

Organizations should produce well-secured software with minimal security vulnerabilities in its releases.


PW.1

Design Software to Meet Security Requirements and Mitigate Security Risks: Identify and evaluate the security requirements for the software; determine what security risks the software is likely to face during operation and how the software’s design and architecture should mitigate those risks; and justify any cases where risk-based analysis indicates that security requirements should be relaxed or waived. Addressing security requirements and risks during software design (secure by design) is key for improving software security and also helps improve development efficiency.


To satisfy SSDF PW.1 in a post-deployment context using open-source tools, the focus shifts to:

  • Keeping a tamper-proof record of every software component in each release

  • Ensuring provenance data remains accessible for audits, investigations, and vulnerability response

  • Allowing acquirers and downstream users to independently verify the origin and integrity of every component

Tasks Tools

PW.1.1: Use forms of risk modeling, such as threat modeling, attack modeling, or attack surface mapping to help assess the security risk for the software.


PW.1.2: Track and maintain the software’s security requirements, risks, and design decisions.


PW.1.3: Where appropriate, build in support for using standardized security features and services (e.g., enabling software to integrate with existing log management, identity management, access control, and vulnerability management systems) instead of creating proprietary implementations of security features and services.
