RDS Instances Associated with Public Subnets

RDS Instances Associated with Public Subnets

Overview

The RDS Instances Associated with Public Subnets widget identifies RDS instances that are configured within public subnets. This insight is vital for IT Operations (IT Ops) and Security Operations (Sec Ops) engineers to ensure secure database deployments, prevent unnecessary public exposure, and maintain compliance with security best practices.

Why It Matters

For IT Engineers:

1. Network Visibility:

   • Highlights RDS instances that are accessible through public subnets, enabling IT Ops to reconfigure them for private network environments.

   • Ensures database deployments align with secure and optimal network configurations.

2. Operational Integrity:

   • Reduces the risk of performance issues caused by unauthorized or excessive traffic to publicly accessible databases.

   • Supports the use of controlled network environments for better stability.

3. Compliance and Governance:

   • Ensures RDS configurations meet organizational policies and regulatory requirements by avoiding public subnet deployments.

For Security Engineers:

1. Risk Mitigation:

   • Identifies RDS instances exposed to public networks, reducing the likelihood of unauthorized access or attacks.

2. Data Protection:

   • Secures sensitive data by ensuring database instances are not unnecessarily accessible from the internet.

3. Policy Enforcement:

   • Enforces compliance with security standards by requiring private subnets for database deployments.

Practical Applications

• Reconfiguration: Migrate RDS instances from public to private subnets to reduce exposure and enhance security.

• Incident Response: Secure databases deployed in public subnets during a security event to prevent data breaches.

• Audit and Monitoring: Regularly review RDS configurations to ensure instances are not inadvertently placed in public subnets.
