Fugue today unveiled a 1.0 release for Regula, an open source policy engine for infrastructure-as-code (IaC) security that comes with prebuilt libraries for implementing hundreds of policies that validate configurations on Amazon Web Services (AWS), Microsoft Azure and Google Cloud services.
Regula is based on the Open Policy Agent (OPA) software being advanced under the auspices of the Cloud Native Computing Foundation (CNCF) and is compatible with both Terraform and AWS CloudFormation tools for configuring cloud infrastructure.
Developers can also build custom rules on top of OPA using libraries that Fugue created for the Rego programing language that is part of the OPA specification. Regula supports output formats such as JUnit, Test Anything Protocol (TAP) and JSON to make it easier to integrate Regula with other tools and frameworks that make up a DevOps workflow. Input formats supported include Terraform HCL, Terraform plan JSON, AWS CloudFormation and Serverless Application Model templates.
Regula also provides out-of-the-box support for the CIS Foundations Benchmarks in addition to other policies defined by Fugue, such as dangerously permissive identity access management (IAM) policies, Lambda function policies allowing global access, volumes with encryption disabled and untagged cloud resources.
It is deployed as a pre-packaged binary that includes a command line interface (CLI) through which Regula can be incorporated within a DevOps workflow and can be installed using tools such as Homebrew or deployed as a Docker image.
Fugue CEO Josh Stella said Regula provides DevOps teams with an extensive library of rules that check for common security and compliance violations as well as advanced multi-resource misconfigurations. That latter issue is especially challenging because developers typically don’t have much visibility into dependencies that can inadvertently provide cybercriminals with access to, for example, an S3 cloud storage bucket that otherwise appears to be configured properly. Regula will also identify any required resources that might be missing, as well, added Stella.
Stella said Regula 1.0 provides a simpler approach to securing cloud infrastructure. Cloud infrastructure is frequently misconfigured simply because a developer made a mistake. Unfortunately, cybercriminals have become especially adept at scanning cloud platforms for these misconfigurations, noted Stella.
It’s not clear to what degree a backlash might be building against IaC in the wake of recent high-profile breaches of software supply chains. Organizations have embraced IaC tools to make developers more productive. However, each security incident involving a misconfiguration of cloud infrastructure resources makes it all too apparent that developers lack the expertise required to securely provision IT environments. Rather than creating a series of cybersecurity reviews that would reduce developer productivity, Stella said Fugue is making a case for a compliance-as-code approach that developers can readily understand and implement.
One way or another, cloud infrastructure has to become more secure. Business leaders are growing weary of security incidents that, from their perspective, are caused by careless mistakes. Their first instinct is to empower cybersecurity teams to resolve those issues once and for all. The only issue that needs to be resolved now is just how cumbersome those security reviews need to be if developers are provided with the tooling required to secure cloud platforms themselves.
