Traditional, manual security processes can’t keep up with the speed of modern development, which leaves systems vulnerable to attacks.

That’s where Security as Code (SaC) comes in. SaC automates security checks and policies, making them an integral part of the development pipeline. This ensures that security is built into every step without slowing down progress.

In this blog post, we will be exploring the role of SaC in DevSecOps, its benefits in maintaining speed and efficiency.

How Security as Code Fits into DevSecOps

Security as Code (SaC) is embedding security policies directly into the development process as code. Instead of security being a separate task that happens later, SaC integrates it right into the codebase, making security checks automatic and continuous.

In a DevSecOps environment, SaC is a natural fit. DevSecOps combines development, security, and operations into a single, streamlined workflow. With SaC, security isn’t an afterthought; it’s baked into every stage of development. This ensures security is maintained at the speed of modern CI/CD pipelines.

Traditionally, security was a manual process, with teams running checks after development was done. This led to delays and, often, security flaws that were found too late. SaC shifts this by automating security tasks, reducing human error, and making sure security measures are always up to date. By automating these processes, teams can respond to threats faster and ensure reliable, consistent security across every release.

6 Practical Steps to Implement Security as Code

Implementing Security as Code (SaC) is a practical approach to integrating automated security into your development process. Here’s a step-by-step guide to get you started:

1. Identify Security Policies and Requirements

First, define the security rules and requirements that your system must follow. This includes things like who can access what data, how data should be encrypted, and what compliance standards need to be met (e.g., GDPR, HIPAA). By identifying these requirements early, you can determine which policies can be automated, making security a built-in part of your development process rather than a separate task. This reduces the chance of overlooking critical security measures.

2. Integrate Security into CI/CD Pipelines

Once you’ve established your security policies, the next step is to embed security checks into your CI/CD pipelines. Use tools like Jenkins, GitLab CI, or GitHub Actions to run security tests during the build and deployment stages automatically. This way, any potential issues are caught early, before they make it into production. Automating these checks helps prevent vulnerabilities from reaching end users and speeds up the overall development process by catching problems sooner.

3. Implement Infrastructure as Code (IaC)

Infrastructure as Code (IaC) allows you to define and manage your infrastructure using code. Tools like Terraform or AWS CloudFormation let you set up servers, databases, and networks with scripts. Incorporate security settings into these scripts to ensure that every piece of your infrastructure is configured securely from the start. Automating this process helps maintain consistency across environments and reduces the risk of misconfigurations that can lead to security breaches.
