Physical Security
In FIPS terminology, the firmware module is defined as a multi-chip standalone
cryptographic module. The module runs on Lexmark printers listed in Module
Specification section. The printers are made of all production-grade components
and are enclosed in a strong plastic and steel case, which surrounds all of the
module's internal components, including all hardware and firmware.
The cryptographic module conforms to the EMI/EMC requirements specified by
47 Code of Federal Regulations, Part 15, Subpart B, Unintentional Radiators,
Digital Devices, Class A (i.e., for business use).
Operational Environment
The operational environment is non-modifiable and thus not applicable for this
firmware module. The PrintCryption module runs on the Lexmark Linux v2.6 OS,
and configured for single-user mode by default. The operating system is used as
an embedded OS within the Lexmark printers, and there is no direct access to the
OS provided.
