Network Segmentation Strategies for Defense Workloads
Network Segmentation Strategies for Defense Workloads
Blog Article
In the world of government contracting, where Controlled Unclassified Information (CUI) is frequently in play, a flat network is a liability. Network segmentation isn’t just a good security practice—it’s often a compliance necessity under frameworks like NIST 800-171 and CMMC.
Why Network Segmentation Matters
When networks lack segmentation, attackers can move laterally across your infrastructure with ease. In contrast, a segmented environment limits the blast radius of any compromise, helping you:
- Isolate critical systems handling CUI
- Enforce access controls and Zero Trust principles
- Meet compliance requirements for enclave separation
Segmenting in a GCC High Environment
Microsoft 365 GCC High supports logical segmentation through:
- Role-based access controls (RBAC) and Azure AD conditional access
- Dedicated security groups for high-sensitivity workloads
- Microsoft Defender for Endpoint’s threat containment features
Additionally, combining network-level segmentation (via firewalls and VPNs) with identity-based segmentation creates layered defense.
Practical Steps to Start Segmenting
- Inventory and classify assets by sensitivity level and user role
- Create separate enclaves for CUI vs. non-CUI workloads
- Enforce least privilege access to each segment
- Implement microsegmentation using tools like Azure Firewall and Microsoft Defender
- Continuously monitor for policy drift and unauthorized access attempts
Benefits Beyond Compliance
Segmentation improves:
- Incident response time and precision
- Audit readiness and documentation
- Organizational resilience against ransomware and APTs
