A host device access monitoring and reporting system includes a management system coupled to server devices through a network. Each server device includes a BIOS that generates and transmits pre-boot access event reports for pre-boot access events occurring prior to the completion of a boot process for that server device, and an operating system that generates and transmits post-boot access event reports for post-boot access events occurring subsequent to the completion of the boot process for that server device. A remote access controller in each server device receives pre-boot access event reports from the BIOS in that server device and, in response, publishes pre-boot access event notifications to the management system. The remote access controller in each server device also receives the post-boot access event reports from the operating system in that server device and, in response, publishes post-boot access event notifications to the management system.
