Various embodiments of the present technology provide methods for activating a security module of a rack system prior to the loading of an operating system. The security module can be configured to examine server platform security, communicate with an administrator through a baseboard management controller (BMC), certify signatures of firmware pieces on a motherboard of the rack system, exclude malware by isolating unsigned UEFI images, examine a signature list and security key installed on the motherboard, and/or report status of security management to a controller of the rack system (e.g., BMC). When the security module determines that an uncertified firmware or a bootable storage with malware is loaded onto the rack system, the security module can stop process(es) associated with the uncertified firmware and/or the bootable storage, and subsequently send a report the administrator.

Security management for rack server system

Various examples of the present technology provide systems and methods for testing whether there is any memory error in a server system, determining physical memory addresses corresponding to a detected memory error on one or more memory devices of the server system, and preventing the physical memory addresses corresponding to the detected memory error from accessing by an operating system, application programs, and/or other components of the server system.
