11.2 Protecting Data Using the Secure User Mode
During normal operation, the R&S FSW uses a solid-state drive to store its operating
system, instrument firmware, instrument self-alignment data, and any user data cre-
ated during operation. If necessary, the solid-state drive can be removed from the
R&S FSW and locked in a secure place to protect any classified data it may contain.
Redirecting storage to volatile memory
Alternatively, to avoid storing any sensitive data on the R&S FSW permanently, the
secure user mode was introduced (option R&S FSW-K33). In secure user mode the
instrument’s solid-state drive is write-protected so that no information can be written to
memory permanently. Data that the R&S FSW normally stores on the solid-state drive
is redirected to volatile memory instead, which remains available only until the instru-
ment is switched off. This data includes:
●
Windows operating system files
●
Firmware shutdown files containing information on last instrument state
●
Self-alignment data
●
General instrument settings such as the IP address
●
Measurement settings
●
User data created during operation
(see also Table 11-1)
●
Any data created by other applications installed on the R&S FSW, for example text
editors (Notepad), the Clipboard, drawing tools, etc.
Users can access data that is stored in volatile memory just as in normal operation.
However, when the instrument’s power is switched off, all data in this memory is
cleared. Thus, in secure user mode, the instrument always starts in a defined, fixed
state when switched on.
To store data such as measurement results permanently, it must be stored to an exter-
nal storage device, such as a memory stick.
