Abstract: Disclosed systems and methods address escalated vulnerability attributable to system down time. In at least one embodiment, a customer-selectable threshold of detection establishes the number of days a system is allowed to be “down” before forcing a secured update path as described herein. The threshold may represent a compromise and balance between inconvenience and security based on each customer's preference. Tracking of system down time or offline time may be managed via EC/SBIOS and a real time clock (RTC) timer. The system down time may then be compared to the customer setting, e.g., whenever the system is booted.
