Securing Cloud-Native Apps with Amazon VPC for Private Networking

OneData Software offers robust solutions for securing cloud-native applications by leveraging Amazon Virtual Private Cloud (VPC) along with complementary AWS security features to provide strong networking isolation, secure communications, and controlled access. Their approach blends infrastructure design, network controls, encryption, and operational best practices to help clients run applications in secure, compliant, and performant architectures.

Key Capabilities & Practices

1. Private Network Isolation o Use Amazon VPC to isolate application infrastructure—defining private vs public subnets so that internal services are not exposed to the Internet unless explicitly needed. o Place application servers, databases, or microservices within private subnets, where only certain layers (e.g. Load Balancers) are in public subnets.

2. Secure Traffic Flow & Segmentation o Use Security Groups and Network Access Control Lists (NACLs) to limit inbound/outbound traffic to only what is needed. o Enforce least-privilege network paths between different components (e.g. app → DB, etc.).

3. Encrypted Data Transmission & Storage o Require TLS/HTTPS for all external and internal communications. o Encrypt data at rest using AWS services (e.g. KMS) for storage systems inside the VPC (e.g., RDS, S3 with VPC endpoints, EBS).

4. Private Connectivity o Use VPC endpoints (for S3, DynamoDB, other AWS services) to avoid public internet exposure. o Possibly use VPN / Direct Connect or AWS Transit Gateway where needed for hybrid or multi-account architectures.

5. Multi-Account / Multi-Tenancy & Governance o OneData helps clients structure AWS accounts, VPCs, and networking to support isolated environments (e.g., development, staging, production). o Ensure policies, route tables, peering, etc., are managed securely.

6. Access Control & Identity Integration o Integration with IAM policies, roles to manage which services/users can modify or access resources inside VPC. o Possibly use additional layered controls like AWS WAF, Security Hub, AWS Shield, etc., as needed.

7. Logging, Monitoring & Audit Trails o Enable VPC Flow Logs, CloudWatch or other logging to capture traffic data, detect anomalous traffic. o Use AWS CloudTrail for configuration / control plane logging. o Use monitoring / alerting to catch misconfigurations or unexpected exposure.

8. Compliance, Best Practices & Hardened Architecture o Ensure architecture follows AWS Well-Architected guidelines (security, reliability, etc.). o Use best practices for subnet design, bastion hosts if needed, security group hygiene, etc. o Possibly use AWS Control Tower to enforce baseline guardrails across accounts.

Benefits

• Reduced attack surface by isolating resources in private networks • Better control and auditability over network access and configuration changes • Enhanced confidentiality and integrity of data transfers and stored data • Improved compliance with regulations (e.g. HIPAA, GDPR, etc.) • More resilient infrastructure; ability to safely host sensitive components
