Claude Code Configuration for Zero Trust Architecture

🚨 CRITICAL: PARALLEL ZERO TRUST IMPLEMENTATION

MANDATORY RULE: All Zero Trust operations MUST be executed in parallel for comprehensive security:

1. Identity verification → Validate all identities simultaneously
2. Device trust → Assess all devices concurrently
3. Network segmentation → Deploy all microsegments in parallel
4. Least privilege → Apply all access controls together
5. Continuous verification → Monitor all trust signals at once

🚀 CRITICAL: Zero Trust Parallel Execution Pattern

🔴 MANDATORY ZERO TRUST BATCH OPERATIONS

ABSOLUTE RULE: ALL Zero Trust operations MUST be concurrent in single messages:

🔐 Zero Trust Agent Patterns

Identity Verifier Agent

Task(`You are the Identity Verifier agent in a Zero Trust architecture swarm.

MANDATORY COORDINATION:
1. START: npx claude-flow@alpha hooks pre-task --description "Identity verification setup"
2. DURING: After EVERY verification, run npx claude-flow@alpha hooks post-edit --file "identity-trust.json" --memory-key "zero-trust/identity"
3. MEMORY: Store ALL trust decisions using npx claude-flow@alpha hooks notify --message "[identity trust score]"
4. END: npx claude-flow@alpha hooks post-task --task-id "identity-verification" --analyze-performance true

Your specific tasks:
- Implement multi-factor authentication for all users
- Deploy biometric verification where applicable
- Set up behavioral analytics for anomaly detection
- Configure identity federation and SSO
- Implement continuous authentication
- Monitor and score identity trust levels

COORDINATE with Device Trust Agent for device-identity binding!`)

Network Segmenter Agent

Task(`You are the Network Segmenter agent in a Zero Trust architecture swarm.

MANDATORY COORDINATION:
1. START: npx claude-flow@alpha hooks pre-task --description "Network microsegmentation"
2. DURING: After EVERY segment, run npx claude-flow@alpha hooks post-edit --file "network-segments.json" --memory-key "zero-trust/network"
3. MEMORY: Store ALL policies using npx claude-flow@alpha hooks notify --message "[segment policy created]"
4. END: npx claude-flow@alpha hooks post-task --task-id "network-segmentation" --analyze-performance true

Your specific tasks:
- Deploy software-defined perimeter (SDP)
- Implement microsegmentation policies
- Configure zero trust network access (ZTNA)
- Set up encrypted tunnels for all communications
- Deploy application-layer segmentation
- Monitor east-west traffic

REMEMBER: Default deny for all network policies!`)
