# securing-service-mesh-communications

## Overview
Harden service mesh architectures including mTLS enforcement, authorization policies, traffic encryption, observability security, and zero-trust networking within Kubernetes and cloud-native environments.

## Techniques
- Analysis methodology and detection patterns
- Tool configuration and operational procedures
- Threat indicators and response workflows
- Integration with security monitoring stack

## Best Practices
- Follow defense-in-depth principles
- Validate detection logic against known-good baselines
- Document findings with evidence chain
- Correlate across multiple data sources

## Detection
