aws-cloudformation-security SKILL.md skillA
aws-cloudformation-security from giuseppe-trisciuoglio/developer-kit is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add giuseppe-trisciuoglio/developer-kit/aws-cloudformation-security@git:20260324.a02e282Pins git:20260324.a02e282 in mdr.lock. Pin the fingerprint instead.

Provides AWS CloudFormation patterns for security infrastructure including KMS encryption, Secrets Manager, IAM security, VPC security, ACM certificates, parameter security, outputs, and secure cross-stack references. Use when implementing security best practices, encrypting data, managing secrets, applying least privilege IAM policies, securing VPC configurations, managing TLS/SSL certificates, and implementing defense in depth strategies.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AWS CloudFormation Security Infrastructure
## Overview
Create production-ready security infrastructure using AWS CloudFormation templates. This skill covers KMS encryption, Secrets Manager, IAM security with least privilege, VPC security configurations, ACM certificates, parameter security, secure outputs, cross-stack references, CloudWatch Logs encryption, defense in depth strategies, and security best practices.
## When to Use
- Implementing KMS encryption at rest and in transit
- Managing secrets with Secrets Manager and automatic rotation
- Applying IAM least privilege policies and permission boundaries
- Securing VPC with security groups, NACLs, and VPC endpoints
- Managing TLS/SSL certificates with ACM
- Encrypting CloudWatch Logs and S3 buckets
- Creating secure cross-stack references and outputs
## Instructions
Follow these steps to create security infrastructure with CloudFormation:
### 1. Define KMS Encryption Keys
Create customer-managed keys for encryption:
```yaml
Resources:
EncryptionKey:
Type: AWS::KMS::Key
Properties:
Description: Customer-managed key for data encryption
KeyPolicy:
Statement:
- Effect: Allow

How to install
mdr add giuseppe-trisciuoglio/developer-kit/aws-cloudformation-security@sha256:eeee8c4e84ea644fThe line at the top of this page pins the label git:20260324.a02e282, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
