What's new in v1.2.0

• Drift detection — cloudcompliance drift catches when AWS resources change outside Terraform
• SNS alerts — automatic notification when drift is found
• Drift report — compliance/drift_report.json with remediation steps
• CI integration — drift check runs on every PR alongside compliance gate

CloudCompliance — SOC2-Ready AWS IaC

Infrastructure as Code that provisions a SOC2-aligned AWS security baseline in one command. Zero manual security configuration required. with 10 controls and 46 AWS resources — deployable in one command.

The Problem

Startups spend 6–12 months retrofitting SOC2 controls onto infrastructure that was never designed to be compliant. Security is an afterthought — CloudTrail gets enabled after an incident, encryption gets added before an audit, RBAC gets tightened only when required.

This IaC eliminates that retrofit entirely. Every SOC2 control is provisioned automatically at infrastructure creation time.

SOC2 Control Coverage

Control	Title	Resources Enforced
CC6.1	Network Isolation	VPC, private subnets, deny-all security group
CC6.2	Authentication Controls	IAM password policy, MFA alert, least-privilege role
CC6.3	Access Revocation	IAM role policies, access analyzer alarms
CC6.6	Transmission Protection	HTTPS-only S3 bucket policy, TLS enforcement
CC6.7	Encryption at Rest	KMS CMK, S3 server-side encryption
CC7.1	Threat Detection	CloudWatch alarms, AWS Config recorder + rules
CC7.2	Audit Logging	Versioned audit bucket, VPC flow logs, Config delivery
CC7.3	Incident Response	Log metric filters, unauthorized API call detection
CC8.1	Change Management	IaC-controlled infra, Config recorder status
A1.1	Availability	S3 versioning, retention policies, backup role

Scope note: This IaC implements the technical infrastructure controls mapped to SOC2 Common Criteria CC6-CC8. Full SOC2 Type II certification additionally requires organizational policies, vendor management, employee training, and 6-12 months of evidence collection — which are outside the scope of infrastructure code.

What Gets Provisioned (46 resources across 9 modules)

Networking — CC6.1

• Private VPC (10.0.0.0/16) with 2 private subnets
• No public subnets — zero internet exposure by default
• Default-deny security group
• VPC Flow Logs → CloudWatch (90-day retention)

Logging — CC7.2

• Dedicated audit S3 bucket with versioning
• Delete protection + HTTPS-only policy
• AWS Config delivery channel

Encryption — CC6.7

• KMS Customer Managed Key with automatic rotation
• S3 encrypted data bucket with KMS SSE
• HTTPS-only bucket policy

IAM — CC6.2 + CC6.3

• Password policy: 14 chars, complexity, 90-day rotation
• Least-privilege IAM role — S3 read + KMS decrypt only
• Access analyzer role + findings alarm
• SNS topic for root account alerts

Monitoring — CC7.1

• CloudWatch alarms: root login, public bucket detection
• AWS Config recorder — all resource types
• Config rules: S3 public read prohibited, S3 encryption required, root MFA

Incident Response — CC7.3

• CloudWatch log group for security events (365-day retention)
• Log metric filters: unauthorized API calls, console sign-in failures
• CloudWatch alarms wired to SNS for both filters

Availability — A1.1

• Versioned availability logs bucket
• Public access blocked
• Backup IAM role

Config — CC7.1 + CC7.2

• AWS Config recorder + delivery channel
• 3 managed Config rules

Change Management — CC8.1

• All resources IaC-controlled via Terraform
• Config recorder status tracking
• CI/CD gate on every PR

Quick Start

Requirements: Terraform, Docker

# 1. Start LocalStack
docker run --rm -d -p 4566:4566 localstack/localstack:3.4.0

# 2. Deploy all SOC2 controls
make deploy

# 3. Generate compliance evidence report
make report

# 4. Check for infrastructure drift
make drift

Use as a Terraform Module

module "soc2_baseline" {
  source  = "KADHIRAVANEG/cloudcompliance/aws"
  version = "1.0.0"

  project_name = "my-startup"
  environment  = "prod"
  aws_region   = "us-east-1"
}

terraform init
terraform apply

Install the CLI

pip install cloudcompliance
cloudcompliance report

# Detect infrastructure drift
cloudcompliance drift

# Detect drift against real AWS
cloudcompliance drift --endpoint ""

Docker Usage

# Pull the image
docker pull ghcr.io/kadhiravaneg/terraform-aws-cloudcompliance:latest

# Run against your terraform state
docker run -v /path/to/your/terraform:/app/terraform \
  ghcr.io/kadhiravaneg/terraform-aws-cloudcompliance:latest

# Run against this repo's state
docker run -v ~/cloudcompliance/terraform:/app/terraform \
  ghcr.io/kadhiravaneg/terraform-aws-cloudcompliance:latest

Expected output:

╭────────────────────────────────────────╮
│ CloudCompliance — SOC2 Evidence Report │
│ Total resources provisioned: 29        │
╰────────────────────────────────────────╯
SOC2 Compliance Score: 100% (7/7 controls passing)

CI/CD Pipeline

Every pull request automatically runs:

1. Terraform Validate — format + syntax check
2. Checkov Security Scan — static analysis against 500+ security rules
3. SOC2 Compliance Check — deploys to LocalStack, runs report, blocks if score < 100%

---

Deploying to Real AWS

# 1. Configure AWS credentials
aws configure

# 2. Deploy to real AWS
make deploy-prod

For production, uncomment the S3 backend in terraform/backend.tf to enable remote state with DynamoDB locking.

Honest scope: This IaC implements the technical infrastructure controls for SOC2 Common Criteria CC6–CC8 and Availability A1. Full SOC2 Type II certification additionally requires organizational policies, vendor management, employee training, and 6–12 months of evidence collection — which are outside the scope of any IaC tool.
