This is a stub project writeup to expand later.

Working Notes

  • Organization: Renown Health
  • Theme: Network access control
  • Summary: Replaced manual sticky-MAC port security with Cisco ISE across roughly 5,000 devices, eliminating recurring desktop-swap calls and moving the network to automated policy-based access control.

To Flesh Out

  • Why sticky-MAC failed operationally
  • Policy model
  • Medical-device considerations
  • Support-call reduction
