Managing Compliance & Security with AWS Config

AWS Config continuously monitors and records AWS resource configurations and allows you to automate compliance checks.

Why AWS Config?

✔ Security & Compliance – Ensures AWS environments meet organizational policies. ✔ Change Tracking – Audits resource changes over time. ✔ Automated Compliance Reporting – Evaluates compliance automatically based on predefined rules.

🔹 SecureCart Use Case: Enforcing IAM Password Policy Compliance

SecureCart, an e-commerce company, must ensure all IAM users follow a password policy requiring: ✅ Minimum 12-character passwords ✅ Use of uppercase, lowercase, numbers, and symbols ✅ Password expiration every 90 days

✅ SecureCart’s Implementation Steps

1️⃣ Enable AWS Config to monitor IAM password policies. 2️⃣ Use AWS Managed Rule: iam-password-policy-check. 3️⃣ Set up automatic compliance evaluation to check IAM password policies. 4️⃣ Configure SNS alerts to notify the security team if non-compliant passwords are detected.

✅ Outcome: SecureCart ensures all IAM users follow the password policy automatically.

🔹 AWS Config Use Cases

🔹 Use Case 1: Monitoring IAM Password Policy Compliance

🔹 Scenario: SecureCart's security team needs to enforce strong IAM password policies. 🔹 Solution: ✔ Use AWS Config Managed Rule (iam-password-policy-check). ✔ Schedule periodic compliance evaluations. ✔ Trigger notifications if IAM users don’t meet password policy requirements.

✅ AWS Config automatically detects non-compliant users and alerts administrators.

---

🔹 Use Case 2: Ensuring S3 Buckets Are Not Public

🔹 Scenario: SecureCart stores customer order data in S3 buckets and must ensure they are private. 🔹 Solution: ✔ Enable AWS Config Managed Rule (s3-bucket-public-read-prohibited). ✔ AWS Config continuously evaluates bucket policies. ✔ Alerts security teams if a bucket becomes public.

✅ Prevents accidental public exposure of sensitive customer data.

---

🔹 Use Case 3: Detecting Unencrypted EBS Volumes

🔹 Scenario: SecureCart’s compliance team requires all EBS volumes to be encrypted. 🔹 Solution: ✔ AWS Config Managed Rule (encrypted-volumes). ✔ Automatically identifies and reports non-encrypted EBS volumes. ✔ Enforces encryption using AWS Lambda automation.

✅ Ensures all EBS volumes follow encryption policies automatically.

---

✅ Best Practices for AWS Config

✔ Enable AWS Config across all AWS accounts for centralized monitoring. ✔ Use Managed Rules where possible to reduce overhead. ✔ Set up automatic remediation actions using AWS Lambda & Systems Manager. ✔ Integrate with AWS Security Hub to enhance security visibility. ✔ Monitor AWS Config compliance reports regularly.

⚠️ Common Mistakes & How to Avoid Them

Mistake	Impact	Solution
Not enabling AWS Config across all accounts	Compliance gaps in multi-account setups.	Use AWS Organizations AWS Config Aggregator.
Using only manual compliance checks	Delayed detection of security issues.	Automate with AWS Config Rules & Remediation Actions.
Not integrating AWS Config with Security Hub	Missed security alerts & compliance reports.	Enable AWS Security Hub integration.
Ignoring non-compliant resources	Leaves security vulnerabilities open.	Set up SNS alerts for immediate action.

🔹 Summary

✔ AWS Config continuously evaluates AWS resource configurations. ✔ SecureCart uses AWS Config to enforce IAM password policies, S3 security, and encryption requirements. ✔ Best practices include using managed rules, automation, and Security Hub integration. ✔ Avoid common mistakes like ignoring non-compliance and failing to automate remediation.

Concept	How AWS Config Helps
Data Access & Governance	AWS Config evaluates IAM policies, permissions, and access control configurations.
Data Retention & Classification	Monitors if S3 bucket policies enforce correct retention & classification rules.
Encryption & Key Management	Checks if EBS volumes, RDS databases, and S3 buckets are encrypted.
Compliance Monitoring	Automates compliance checks for regulatory frameworks (e.g., HIPAA, PCI-DSS).
Implementing Access Policies	Enforces IAM password policies, S3 bucket security, and least-privilege access.
