1. An information handling system ransomware protection method comprising:
implementing, by storage device ransomware protection logic, secure snapshot policies in a domain of a storage device by taking a secure snapshot of a data object, comprising creating a point in time image of a storage object and retaining the point in time image of the storage object until a retention timer has expired;
implementing, by the storage device ransomware protection logic, snapshot virtualization in the domain of the storage device by mapping the secure snapshot;
creating a secure snapshot of a boot device of the information handling system;
creating a secure alternate boot device on each boot of the information handling system;
exporting the secure alternate boot device to a basic input/output system of the information handling system; and
configuring a boot order of the information handling system with the secure alternate boot device immediately after the boot device in the boot order.
