What is Security as Code?

In today’s business landscape, software holds an increasingly vital role, and organizations are racing to achieve innovation and rapid release to stay competitive. However, the quest for rapid software delivery also brings about inherent risks. Many companies have shifted from traditional waterfall development methodologies to DevOps approaches to hasten their time-to-market. Yet, this acceleration can introduce vulnerabilities. To address this challenge, security must be seamlessly integrated at every stage of the software development lifecycle (SDLC), necessitating the automation of security tools and processes.

Security as code (SaC) emerges as the discipline aimed at integrating security into DevOps tools and processes, seamlessly infusing security checks, tests, and gates throughout the development process. Developers can craft specific code for infrastructure platforms and configurations, fostering agility and velocity while ensuring security. This approach aligns with the future trajectory of application security, where security as code will likely shape the landscape.

Implementing security as code involves embedding security rules, policies, tools, tests, and scans into the CI/CD pipeline and the code itself. As code is committed, automated tests are conducted, enabling prompt feedback for developers to address any issues. This real-time security scan approach optimizes resource utilization, saving both time and money within the software development lifecycle.

Why is Security as Code Important?

Transitioning from DevOps to the integrated DevSecOps approach necessitates the embrace of security as code. Defining security requirements at the project’s inception and ensuring coded and automated implementation ensures consistency and reusability. This automation translates into improved release velocity and a more focused security team. The team’s energies are redirected from routine SDLC contributions to tackling zero-day vulnerabilities and enhancing existing or upcoming products.

Furthermore, adopting consistent policies and processes fosters a uniform security posture across all development activities and staff. This uniformity translates into heightened overall product security and reduced incidents, and outages, ultimately leading to increased customer satisfaction.

Components of Security as Code

Security as code encompasses access control and policy management, vulnerability scanning, and security testing. These components empower development teams to identify and rectify security issues during the early stages of the software development lifecycle. This approach nurtures a collaborative ethos between development and security teams, with security becoming an integral part of every stage.

  • Access control and policy management involve formalizing governance decisions and authorization policies. Developers can offload authorization to external libraries, thus accelerating the organization’s pace while maintaining security compliance.
  • Vulnerability scanning ensures that each component of an application is safeguarded against known vulnerabilities. Source code is scanned to identify vulnerable libraries, while applications are checked for OWASP vulnerabilities such as XSS and SQL injection. Containers are examined for compliance with best practices and vulnerabilities in specific packages.
  • Security testing encompasses code examination to identify issues that could compromise the application’s Confidentiality, Integrity, or Availability. It not only prevents threats but also detects configuration errors, data breaches, exposed secrets, and vulnerabilities that could be exploited.

The Benefits of Security as Code

Security as code enhances application security and elevates operational baselines. It facilitates quicker adoption of security requirements and fosters collaboration among security, development, and operations teams. This “shift left” approach identifies and remedies vulnerabilities earlier, reducing costs and increasing development velocity. Customer satisfaction improves through faster release cycles and enhanced security visibility.

Implementing Security as Code

Transitioning to security as code involves establishing security policies and writing the code that implements those policies and baselines. Collaboration among development, operations, and security teams is essential to understanding the current state of application security. Training and upskilling teams are crucial to this shift. Organizations can then evaluate toolsets that integrate security throughout the software development lifecycle, ensuring the implementation of real-time scanning, policy enforcement, vulnerability detection, and actionable results.
