After the firewall begins logging mobile device traffic, it forwards the traffic
metadata in GTP logs to the logging service, which in turn streams it to
Device Security. To check the status of the GTP logs,
log in to the Device Security portal and select . There you can see if Device Security is
receiving GTP logs, the time of the latest log, and how many GTP log events and
bytes it’s received.
To see mobile device attributes in the device inventory on the
Devices page, select . Because the Mobile Device columns are hidden by default, click
the icon with three vertical bars to open the column selection panel, and select
all the columns you want to see. All the columns displaying mobile device
attributes are available in the Mobile section:
Mobile Equipment Identity – The 15-to-17-digit code
assigned to every mobile device to uniquely identify it International
Mobile Equipment Identity (IMEI)
Mobile Subscriber Identity – A unique identifier issued
on a Subscriber Identity Module (SIM) card. In 2G, 3G, and 4G networks,
this identifier is referred to as International Mobile Subscriber
Identity (IMSI). In 5G networks, it is called Subscription Permanent
Identifier (SUPI).
Mobile Subscriber ISDN – The Integrated Services Digital
Network number is a mapping of a cellular telephone number to a mobile
subscriber
Mobile APN (Access Point Name) – Term used to identify
the external Packet Data Network (PDN) to which mobile devices connect
through the 2G, 3G, or 4G cellular network. In a 5G network, it refers
to the Data Network Name (DNN).
Radio Access Technology – The underlying connection
method mobile devices use for wireless radio communications; for
example, Bluetooth, Wi-Fi, UMTS, LTE, or 5G NR
Mobile Base Station Code – The identification number
that uniquely identify a cellular base station
Mobile Area Code – The area code of the user’s
location
Mobile Network Code (MNC) – A two-digit (European
standard) or three-digit (North American standard) number identifying
the Public Land Mobile Network (PLMN) of the mobile subscriber
Mobile Country Code (MCC) – A three-digit number
identifying the country of the mobile subscriber
Mobile TAC (Type Allocation Code) – An eight-digit
number that identifies the manufacturer of a mobile device
Network Slice – The logically discrete section of
network operating over a common infrastructure
Mobile Device – The end user device operating on a wireless
network
In addition to showing columns with these attributes in the inventory table, you
can also use them in
filters and queries at the top of the
Devices page. They are displayed on the
Device Details page of mobile devices and are available
for use when creating
custom alert rules.
