4.7.5 Sanitizing the Unit
The concept of sanitizing a SecureSync unit refers to erasing usage data that may be stored in
volatile and/or non-volatile memory, i.e. permanently eliminating any data that could be used
to trace the unit's former usage. This data may include – but is not limited to – logs, con-
figuration settings, IPaddresses, passwords, GNSS geographic positioning data, and network-
specific usage data.
From a top level, cleaning a SecureSync involves restoring the following to factory default con-
figurations:
1.
The file system on the Compact Flash (CF) card is restored to factory state by removing
the logs and restoring all configuration files to the default factory state.
2.
Commercial GPS/GNSS receivers have stored position data deleted, and are setup to
resurvey on reboot.
The command line gpsreset clean option erases the GPS/GNSS receiver flash
memory, returning it to factory state and setting up to resurvey.
