⌚ Cryptographic Network Security: Apple Watch Audio Streaming AI Assistant

Watch the Apple Watch Demo

Github .md post

Designed and implemented a defense-in-depth security stack for real-time audio streaming between an Apple Watch and a home server.

  • Custom X.509 PKI enrollment workflow with mutual TLS (mTLS) - LAN-only enrollment tied to physical proximity
  • AES-128-GCM encrypted UDP transport with cryptographic nonce derivation and replay protection via sequence numbers
  • Certificate-based identity using the Apple Watch Secure Enclave (private key never leaves hardware)
  • Three-port architecture separating enrollment, session auth, and media transport
  • Integrated LangGraph AI assistant as the application layer

πŸ“Š SIEM Lab: Splunk on Oracle Cloud Infrastructure

SIEM Lab

Github .md post

Deployed a cloud-based SIEM pipeline with secure log forwarding and automated rate-limit enforcement.

  • Provisioned OCI free-tier instances with Tailscale ACL network segmentation
  • Automated log collection pipeline: rsyslog β†’ rsync β†’ logrotate β†’ Splunk Universal Forwarder
  • Built an OCI SDK shell script that monitors log volume and enforces API-based ingress lockdown to stay within Splunk's 500 MB/day free-tier limit
  • Built SPL dashboards to visualize live SSH brute-force trends by source IP, geolocation, and daily occurrence rate
