3.10 Security
The security concept of ZED-F9K covers the air interface between the receiver and the GNSS
satellites and the integrity of the receiver itself.
There are functions to monitor/detect certain security threads and report it to the host system.
Other functions try to mitigate the thread and allow the receiver to operate normally.
The table below gives an overview about possible threads and which functionality is available to
detect and/or mitigate it.

Over air signal integrity Spoofing detection/mitigation
Jamming detection/mitigation
GNSS receiver integrity Secure boot
Secure firmware update

3.10.1 Spoofing detection / monitoring
Spoofing is the process whereby someone tries to forge a GNSS signal with the intention of fooling
the receiver into calculating a different user position than the true one.
