Network Microsegmentation and Zero Trust Networking

Network microsegmentation creates granular security zones that limit lateral movement and reduce the blast radius of potential security breaches.

Software-Defined Perimeter (SDP)

SDP Architecture Components

• SDP controllers for policy enforcement
• SDP initiating hosts (clients)
• SDP accepting hosts (resources)
• Dynamic tunnel creation
• Encrypted communications channels

Implementation Benefits

• Application-specific access controls
• Default-deny network policies
• Invisible infrastructure protection
• Scalable cloud-native deployment
• Reduced attack surface

Network Access Control (NAC)

Device Authentication and Authorization

• Pre-admission security checks
• Post-admission monitoring
• Dynamic VLAN assignment
• Guest network isolation
• Automated remediation actions

Policy Enforcement Points

• Switch-based enforcement
• Wireless access point integration
• VPN gateway controls
• Firewall policy synchronization
• Cloud network security groups

Microsegmentation Strategies

East-West Traffic Control

• Inter-application communication policies
• Database access restrictions
• Service-to-service authentication
• API gateway integration
• Container network policies

Workload Protection

• Virtual machine isolation
• Container orchestration security
• Serverless function boundaries
• Cloud workload protection platforms
• Runtime security enforcement

Network Monitoring and Analytics

Traffic Analysis and Visibility

• Flow-based network monitoring
• Application performance monitoring
• Anomaly detection and alerting
• Compliance reporting
• Forensic investigation capabilities
