What does Compliance-as-Code mean to your Organisation?

An enterprise adopts DevOps in the few years to enhance its software development and delivery process; process compliance is neglected to incorporate faster delivery processes during the development.

Over the past few years, organizations worldwide are now concerned about security and compliance to the requirement of several compliance standards such as GDPR, ISO 27001, HIPAA, PCI DSS, etc., which currently holds business importance. Compliance to the standard has led to the introduction of security and compliance in the early phases of the software development lifecycle, impacting the whole process. Security is not the same as compliance.

Compliance requirements are very complex to correlate and understand. Auditing the entire ecosystem for compliance is very time-consuming and is a costly process. Also, it requires much human effort. But, humans tend to make mistakes, and sometimes even the security team is not aware of the exact requirements stated by the compliance standards. This situation has led to the concept of looking at 'compliance to standards' as Compliance-as-Code, which is now an integral component of DevSecOps and validates DevOps infrastructure compliance. It helps to insert and enforce compliance requirements into the development pipeline to ensure that every release meets the security baseline standards.  

What is Compliance as Code?

Compliance-as-Code means use programmatic methods (code) for automating the implementation, validation, remediation, monitoring, and reporting of the required compliance standards that an organization needs to be compliant with across the entire organization's ecosystem.

The most prominent advantage of using Compliance-as-Code is that it can be used and integrated across the whole compliance lifecycle process. It can be used in the initial design and implementation phase to validate different controls' implementation. It may also be used for performing continuous monitoring and remediating the potential issues. Usage of compliance-as-code enables monitoring the compliance status and provides a report on the CI/CD pipeline if integrated into your CI/CD. Incorporating the compliance-as-code also allows you to monitor real-time changes, validate the differences concerning the desired compliance standards, and report the compliance status.

Compliance is measured against security requirements, such as regulatory compliance and internal governance, benchmarks, the best-practices. When adopting compliance-as-code, you need to determine the security benchmarks and best-practices that you need to follow and regulatory & internal governance requirements that are to be compliant with. Once you have determined all the requirements and appropriate controls, you need to translate those requirements and specified controls into specific rules using code. Finally, you need to integrate or execute these codes to validate a specified resource/service and determine whether that specified resource/service is compliant with the determined requirements and controls.

Why do we need it?

When the requirements and controls for compliance are implemented and validated from the beginning of the development lifecycle using Compliance-as-Code, it is beneficial for everyone to start from developers to external auditors. However, compliance is not a one-time process. It is an essential component of the software development lifecycle. If the first release of a software developed is compliant to the standard, it would be compliant in all future releases. Adopting compliance-as-code will make it easier for the developers and the auditors to validate the compliance requirements and controls.

Let's assume that compliance-as-code is built into the CI/CD pipeline, the developers will come to know the compliance status on every commit and make changes accordingly. In this way, the final version will be 100% compliant. Compliance-as-Code is required over manual enforcement of compliance requirements and the controls as it provides a way for continuous monitoring and reporting of compliance status. 

Compliance-as-Code helps provide greater visibility on the different rules validated at each step of the software development life cycle. Incorporating compliance-as-code such as Shift-left security from the beginning of the software development lifecycle helps the security team determine the risks and the development team to make changes at the early stages leading to on-time delivery reducing the cycle time and both the teams can perform their jobs faster.

The audit trail is one of the most important aspects of compliance. An audit trail must answer the following questions: what was the change? who made the change, who requested the change and why? , was the change tested ?,who reviewed change, was the change tested before being made, who tested the change, when was the test performed, when was the change made, and so on. Following the principle of compliance-as-code provides an audit trail for each and every change that is made.  

Validating and auditing compliance using Compliance-as-Code helps achieve a very high degree of precision as it depends on programmatic methods. When compliance is dependent on manual processes, the results may be too error-prone as humans tend to make errors; also, scalability is easier even in cloud environments. If the environment is scaled up, the defined programmatic methods can also be scaled to match the environment and validate compliance status. Thus, repeatability of the entire process can be achieved very easily, reducing the total level of effort required to deploy and maintain compliant workloads.

Adopting Compliance-as-Code integrated the compliance requirements and controls into different business processes as a mandatory practice. It helps to decrease the compliance knowledge gap. It also helps to prioritize the compliance tasks. For instance, let's say that your automated reports give a list of 20 non-compliant applications. So, you can easily prioritize them based on the criticality of your business needs. It also streamlines the routine reporting process and helps to achieve transparency over the entire compliance process that the management can easily track. 

When using compliance-as-code, the compliance rules are written as code, and all the checks are automated. So, you can easily run your compliance checks again and again after making small changes to validate the compliance status. It also supports automated evidence gathering defined programmatically, simplifying the audit preparation and assessment process. One of the major advantages of having compliance rules written as code is that the rules can easily be tested, versioned, and categorized into bundles, known as compliance bundles. Compliance violations can also be grouped, visualized, and be reported to a centralized dashboard to increase the compliance status visibility.

How do we do it?

Different tools need to be used in different phases of the software development lifecycle to implement Compliance-as-Code. In the planning phase, organizations can use the SecurityRAT open-source tool provided by OWASP. It lets the team create security requirements as code integrated into every project as an auditable artifact.

In the build phase, organizations can use TruffleHog, Gitty Leaks, or Git-Secrets to check for secrets in source code. In this phase, tools such as OWASP Dependency-Check, or retireJS can be used to check for vulnerabilities in known components and vulnerable dependencies. In

the testing phase, organizations can use InSpec by Chef and Open Policy Agent (OPA) tools. For CI/CD, another tool called Conftest, based on OPA can be used to validate various requirements. Conftest helps you write tests against structured configuration data. Using Conftest, you can write tests for your Kubernetes configuration, Tekton pipeline definitions, Terraform code, Serverless configs, or any other config files.

In the case of Kubernetes, Gatekeeper tool is built on top of OPA to validate and audit kubernetes resources both pre and post-deployment. In the deployment phase, organizations prefer CIS benchmarks to harden the industry best practices' systems/services. IT automation frameworks such as IT Chef, Puppet, or Ansible can be used for this purpose.

Compliance as Code's Benefits for your Business 


Adopting Compliance-as-Code helps an organization to achieve visibility across its ecosystem. The stakeholders can easily know what's exactly going on across the organization in terms of compliance status at any given point in time. The organization can easily maintain an audit trail across everything that happened across the development lifecycle and determine a proper risk acceptance score. It also helps the organization evaluate any process's deviations from the minimum compliance requirements.

Scale compliance across the organization

Compliance-as-Code helps the organization to easily and properly scale compliance requirements across the organization. Once the compliance requirements have been converted into codes and scripts and organized into compliance bundles, the entire ecosystem can be easily validated and audited to ensure compliance. Saling compliance requirements also become easier as these compliance bundles can easily be integrated, and automated checks can be performed. It enhances the efficiency of both the security team and the development team as these automated checks provide flexibility to the development team to check the compliance status at any given point of time without bothering or taking support from the security team who can focus on other security challenges. When compliance requirements change, the security team can just release a new compliance bundle.

Avoid Surprises 

Compliance-as-code helps enterprises to articulate the compliance status with zero surprises. When compliance-as-code is integrated into different processes, the organization can rest assured the final outcome will be 100% compliant as any non-compliant scenario can be easily traced and will not be allowed to move forward in the production process until all the compliance rules are successfully validated.

In case of sudden events such as emergency production changes and zero-day vulnerabilities, it becomes easier to maintain compliance by identifying the required machines/object of change and fixing/changing things in a much faster manner as security standards are integrated into the business processes.

Easier Management of Compliance Requirements 

Compliance-as-Code solves the biggest problem of understanding the compliance requirements. Compliance requirement documents are typically very elaborate and complicated to understand. Compliance-as-Code solves this problem by converting those compliance requirements into automated scripts and codes that anyone can easily validate without needing to understand the entire compliance requirement documents. It reduces the cost involved in managing, auditing, and ensuring compliance throughout the entire organizational processes. It helps gather evidence and generate audit reports easily and quickly. It also helps to ensure the scalability and reliability of compliance status.

Compliance as Code Best Practices

Some of the key best practices that need to be followed when implementing Compliance-as-Code are:

  • Prioritize shift-left security and integrate Compliance-as-Code from the beginning of the process chain.
  • Perform thorough testing of the developed security rule to ensure that they don't violate requirements.
  • Consider all the end cases while defining the rules.
    Deploy and test the test environment's policies before deploying them into the production environment.
  • Regularly check for the required modification in policies with changes in compliance standards.
  • Security assessment of application and infrastructure should not be avoided even if Compliance-as-Code is implemented.
  • Automated security reports should be thoroughly reviewed.
  • Always remember, all compliance requirements are not always necessary to enforce.


Compliance-as-Code ensures that the business processes are compliant with various security standards. It enables the security team to write rules that can be used to enforce compliance within the organization and establish security baseline standards. It gives greater visibility to the compliance checks that are validated at each phase of the software development lifecycle.

Implementing Compliance-as-Code from the very beginning of the development lifecycle ensures the timely delivery of a project that tends to be compliant. It allows the security team to build templates and scripts, which can be shared across the organization enabling greater scalability. Compliance is an essential aspect of business and has become a requirement for organizations' growth and development.
