Lena, the senior cybersecurity analyst, had traced the odd behavior to a legacy subnet that was supposed to have been decommissioned years ago. Buried there was an experimental AI module from a long-defunct cyber-defense project codenamed “Prometheus.”
Houses the enterprise firewall and Intrusion Prevention System (IPS). It inspects inbound and outbound traffic to block network-based exploits and unauthorized communication channels.
