Infrastructure as Code Security.

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

rule_id: codeguard-0-iac-security

# Infrastructure as Code (IaC) Security

When designing cloud infrastructure and writing Infrastructure as Code (IaC) in languages like Terraform and CloudFormation, always use secure practices and defaults such as preventing public exposure and follow the principle of least privilege. Actively identify security misconfigurations and provide secure alternatives.

## Critical Security Patterns In Infrastructure as Code

### Network security
- **ALWAYS** restrict the access to remote administrative services, databases, LDAP, TACACS+, or other sensitive services. No service should be accessible from the entire Internet if it does not need to be. Instead, restrict access to a specific set of IP addresses or CIDR blocks which require access.
    - Security Group and ACL inbound rules should **NEVER** allow `0.0.0.0/0` to remote administration ports (such as SSH 22, RDP 3389).
    - Security Group and ACL inbound rules should **NEVER** allow `0.0.0.0/0` to database ports (such as 3306, 5432, 1433, 1521, 27017).

How to install

The exact contents, by fingerprint
mdr add cisco-ai-defense/skill-scanner/.cursor/rules/codeguard-0-iac-security.mdc@sha256:c528d555b7068103

The line at the top of this page pins the label v1.0.1, 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.
