Automated Security Checks for AI DevOps Pipelines

Question

Pulumi · Accepted Answer

To ensure the safety and compliance of DevOps pipelines, especially when incorporating AI elements, it is crucial to implement automated security checks. Automated security checks can be added to your infrastructure as code (IaC) using Pulumi with various security resources provided by cloud providers like AWS and Azure.

In an AWS environment, you often use AWS Security Hub, Inspector, and related services to conduct automated security assessments and manage standards compliance. For instance, AWS Security Hub pulls in findings from various AWS services and third-party tools to provide a comprehensive view of your security posture. AWS Inspector can be used to run security assessment scans on your application to identify potential security issues.

In an Azure environment, you might use Azure Security Center, which also provides a unified security management system that strengthens your security posture and protects against threats.

For the purpose of our automated security checks within an AI DevOps pipeline, let's design a Pulumi Python program that sets up AWS Security Hub to automatically check for compliance with security standards. In this program, we will:

Enable AWS Security Hub to aggregate security findings.
Choose the set of standards to apply.
Customize the automatic checks as needed.

Here's a detailed program that accomplishes this, explained step by step.

import pulumi
import pulumi_aws as aws

# Enable AWS Security Hub - Centralized security and compliance management system
# Documentation: https://www.pulumi.com/registry/packages/aws/api-docs/securityhub/account/
security_hub = aws.securityhub.Account("securityHub",
    enable_default_standards=False)  # Optionally, you can turn on default standards if needed

# Subscribe to a standard (e.g., CIS AWS Foundations Benchmark standard) within AWS Security Hub to follow security best practices.
# You would pass the ARN for the standard you want to subscribe to here.
# Documentation: https://www.pulumi.com/registry/packages/aws/api-docs/securityhub/standards_subscription/
standard_subscription = aws.securityhub.StandardsSubscription("standardSubscription",
    standards_arn="arn:aws:securityhub:::standards/cis-aws-foundations-benchmark/v/1.2.0")

# Customize security checks for specific standards.
# Here, as an example, we're creating a StandardsControl which could modify individual controls of a standard.
# You would replace the control and standard ARNs with your own.
# Documentation: https://www.pulumi.com/registry/packages/aws/api-docs/securityhub/standardscontrol/
standards_control = aws.securityhub.StandardsControl("standardsControl",
    control_status="ENABLED",
    standards_control_arn="arn:aws:securityhub:<region>:<account>:control/<standard-arn>/<control-id>")

# Export the Security Hub ARN so it can be used to integrate with your DevOps pipelines.
pulumi.export('security_hub_arn', security_hub.arn)

To break down each resource:

aws.securityhub.Account enables the Security Hub service. The enable_default_standards parameter can be toggled to automatically subscribe to all AWS-handled standard checks.
aws.securityhub.StandardsSubscription subscribes your account to a specific security standard. The standards_arn parameter is used to specify which standard you'd like to subscribe to.
aws.securityhub.StandardsControl allows you to enable or disable specific controls within those standards. You need to specify control_status and the ARN of the specific control you want to manage.

Once you've set up the automated security checks with Pulumi, these will run within AWS Security Hub to continuously evaluate your AWS resources and workloads against the chosen security standards.

This template is just the beginning. It can be enhanced by adding more controls, integrating with CI/CD pipeline event triggers, or adding automatic remediation actions using AWS Lambda and other AWS services. Integrating these checks into your DevOps pipelines may involve triggering assessments on code commits, container builds, and deployment events, thereby creating a comprehensive security posture that spans the entire software development lifecycle.
