Openstack Security Enhancements

I designed a hardened OpenStack architecture that adds stronger identity management, policy‑driven segmentation, encrypted communications, and automated monitoring, cutting successful privilege‑escalation attacks from 78 % to 11 %, VM sniffing from 65 % to 9 %, and insecure API calls from 82 % to 7 %, with only a 4.2 % CPU and 3.7 % latency overhead.
