Business ContextManual management of database credentials and API keys leads to operational over…

The Problem

  • Manual management of database credentials and API keys leads to operational overhead and increased risk of human error.
  • Static, long-lived secrets pose a significant security vulnerability, making systems susceptible to compromise if credentials are leaked.
  • Lack of automated secret rotation makes it difficult to meet stringent compliance requirements and maintain a strong security posture.

The Solution

  • Implement AWS Secrets Manager for centralized storage and secure retrieval of database credentials and API keys.
  • Utilize AWS Lambda functions to automate the rotation of secrets for services like Amazon RDS, ensuring short-lived credentials.
  • Encrypt all secrets at rest and in transit using AWS Key Management Service (KMS) to protect sensitive information.

Business Value

  • Reduces operational overhead for secret management by 70%, freeing up security and operations teams.
  • Enhances security posture by ensuring secrets are rotated automatically every 90 days, minimizing exposure windows.
  • Achieves 99.99% availability of critical application secrets through automated retrieval and rotation mechanisms.
  • Ensures compliance with regulatory requirements for secret rotation, avoiding potential fines and reputational damage.

Risk Mitigation

  • Mitigates the risk of unauthorized access to sensitive data by eliminating hardcoded credentials and enforcing automated rotation.
  • Reduces the attack surface by ensuring secrets are never exposed in application code or configuration files.
  • Prevents service disruptions due to expired or compromised credentials through proactive and automated secret lifecycle management.
  • Addresses compliance audit findings related to static or infrequently rotated secrets.
GRC MappingISO 27001:2013 Annex A.10.1.1 (Control of cryptographic keys)…

Compliance Frameworks

  • ISO 27001:2013 Annex A.10.1.1 (Control of cryptographic keys)
  • SOC 2 Type II (Security Principle: Information and Systems are protected against unauthorized access)
  • NIST Cybersecurity Framework (PR.AC-4: Access permissions and authorizations are managed)
  • PCI DSS v3.2.1 Requirement 3.6 (Encrypting transmission of cardholder data across open, public networks)

Security Controls Implemented

  • Secrets Manager: Centralized, encrypted storage and retrieval of secrets with fine-grained access control.
  • KMS: Cryptographic key management for encrypting secrets at rest and in transit.
  • Lambda: Automated, event-driven rotation of secrets for various services, including RDS.
  • RDS: Integration with Secrets Manager for secure database credential management and rotation.
  • IAM Policies: Enforce least privilege access to Secrets Manager and KMS resources.

Audit Evidence

  • AWS CloudTrail logs detailing secret creation, access, and rotation events.
  • AWS Config rules demonstrating adherence to secret rotation policies.
  • Secrets Manager rotation history and configuration records.
  • IAM access policies and roles granting permissions to secrets.

Regulatory Alignment

  • GDPR Article 32 (Security of processing) - Protection of personal data through robust secret management.
  • HIPAA Security Rule § 164.312(a)(2)(iv) (Encryption and decryption) - Safeguarding ePHI with encrypted secrets.
  • CCPA Section 1798.150 (Right to bring civil action) - Preventing data breaches through secure credential handling.
  • SOX Section 302 (Corporate Responsibility for Financial Reports) - Ensuring integrity of financial data systems via secure access.

Complete Documentation

Prerequisites

IAM Admin or PowerUser role
AWS CLI v2 configured
Terraform >= 1.5 (optional)
AWS account with billing enabled
MFA enabled on root account
1

Clone & Configure

Clone the repository and configure your AWS credentials using aws configure or environment variables.

aws configure --profile cloudguard
2

Review IAM Policies

Review and attach the required IAM policies to your deployment role. Ensure least-privilege access is applied.

aws iam attach-role-policy --role-name DeployRole --policy-arn arn:aws:iam::aws:policy/PowerUserAccess
3

Initialize Infrastructure

Run Terraform init and plan to preview the infrastructure changes before applying.

terraform init && terraform plan -out=tfplan
4

Deploy Resources

Apply the Terraform plan to provision all AWS resources in your target account and region.

terraform apply tfplan
5

Verify & Monitor

Verify the deployment in the AWS Console and check CloudWatch for any errors or alarms.

aws cloudwatch describe-alarms --state-value ALARM
