LSPERF12-BP01 Implement network segmentation with defense-in-depth controls
Design the network with clearly defined security zones separated by firewalls, with sensitive data repositories isolated from general network traffic. Employ a layered security approach (defense in depth) with multiple security controls at each boundary. Use VLANs, subnets, and micro-segmentation to isolate data flows based on security levels and functional requirements. This architecture limits potential attack surface and contains breaches should they occur while maintaining efficient routing paths for authorized large data transfers.
Desired outcome: You have a segmented network architecture that provides multiple layers of security controls, supports regulatory requirements, and enables secure collaboration across research teams. This approach protects sensitive life sciences data while maintaining operational efficiency and regulatory alignment.
Level of risk exposed if this best practice is not established: High
Implementation guidance
Network segmentation is fundamental for life sciences organizations handling sensitive data like clinical trials, genomic data, or patient information. By implementing multiple security layers, you create isolation between different data sensitivity levels and reduce the potential attack surface.
This approach aligns with key regulatory requirements including HIPAA, GxP, and GDPR. Segmentation enables clear audit boundaries and demonstrates regulatory adherence by maintaining separate environments for development, validation, and production systems.
Defense in depth controls allow for granular access management and simplified auditing. This architecture supports the isolation of regulated workloads while enabling secure collaboration between research teams, clinical partners, and third-party vendors.
Implementation steps
-
Create separate VPCs for production, development, and test environments with tiered subnets.
-
Deploy AWS Transit Gateway for centralized connectivity between environments.
-
Implement AWS Network Firewall and AWS PrivateLink for secure service access.
-
Configure security groups and Network ACLs following least-privilege principles.
-
Deploy AWS WAF and AWS Shield for application security and DDoS protection.
-
Enable VPC Flow Logs and AWS GuardDuty for comprehensive security monitoring.
-
Establish AWS Security Hub CSPM for centralized audit and security posture management.
-
Configure AWS Site-to-Site VPN for secure remote connectivity to on-premises resources.
