Overview

Hospital dashboards show green lights across the board, but wireless infusion pumps on the ward floor suddenly start throwing constant, confusing connection alerts. The culprit is a hidden testing setup left behind by a clinical vendor, now getting hammered by a brute-force scanning attack that backs up the network.   

Host Christine Bartlett puts Associate CISO Krista Arndt in the executive hot seat. Instead of abstract IT issues, Krista has to deal with exhausted nurses ignoring chirping devices, potential media leaks, and an unvetted vendor code fix.  

Faced with rising operational risks, Krista must make tough calls under pressure: balancing pharmacy delays against network safety, working with legal to handle PR, and deciding whether to run a risky script that could either clear the network or lock up hospital equipment for days.
