Modern applications have brought many benefits and improvements, including the ability to scale and rapid iterations to update software. However, this has come at the cost of complexity. Modern infrastructure is composed of many resources that require detailed configuration to work correctly and securely.

Cloud providers, such as AWS, do allow you to create policies to ensure that applications are secure, but they are specific to resources that are already deployed. A significant benefit of Policy as Code is the ability to verify and spot problems before deploying your infrastructure.

We recently announced a new policy as code solution, CrossGuard that validates policies at deployment time. Policies are expressed as code and are used to prevent the creation of out-of-compliance resources. This allows an organization to prevent entire classes of security and reliability defects to ensure infrastructure is following best practices. Because policies are written using full-blown programming languages, it’s possible to do interesting things such as combining IAM Access Analyzer and Pulumi CrossGuard. In this post, we’ll take a closer look at the different types of policies that can be written.

Yesterday AWS announced an exciting new feature — the AWS Identity and Access Management (IAM) Access Analyzer — a service powered by automated reasoning that detects potentially-insecure access to your AWS resources, including S3 Buckets, SQS Queues, Lambdas, and more. At the same time, Pulumi announced a new policy as code solution, CrossGuard, that validates policies at deployment time. The question is: Can IAM Access Analyzer and Pulumi CrossGuard be combined to get the best of both solutions?

Over the past few months, we have been hard at work on Pulumi CrossGuard, a Policy as Code solution. Using CrossGuard, you can express flexible business and security rules using code.

CrossGuard allows you to verify or enforce custom policies on changes before they are applied to your resources. CrossGuard is 100% open source and available to all users of Pulumi, including the Individual Edition. Advanced organization-wide policy management features are available to Enterprise customers.
