Intelligent Security and the UEIP Database
Learn about the UEIP database that Intelligent Security uses for correlating IP
addresses and user equipment.
Mobile network administrators use identifiers to create zero trust policies
that apply to each subscriber, equipment, application and piece of data in 5G and 4G/
LTE networks. These identifiers include the following:
Subscriber ID, also known as the International Mobile Subscriber Identity
(IMSI)
5G Subscriber Permanent Identifier (SUPI)
Equipment ID, also known as International Mobile Equipment Identity (IMEI)
Permanent Equipment Identifier (PEI)
For example, administrators may want to create security policy for the
following use cases:
To apply subscriber and equipment identity-based security in an enterprise 5G
network
To apply advanced L7 security control for critical infrastructure equipment
connected to 5G networks
To allow a service provider to offer advanced threat prevention service to its
enterprise 5G customers
Intelligent Security correlates user equipment (UE) information with IP
addresses by mapping the 5G or 4G subscriber, 5G or 4G equipment, and 5G network slice
to the IP address associated with traffic from the UE, ensuring consistent security
policy enforcement in your mobile network.
The firewall obtains the UE-to-IP address mappings and adds them to a database
on the firewall, which it queries for the correlated mobile user information to enforce
security policy. The firewall supports multiple sources to obtain the UE-to-IP address
mappings, including PFCP and RADIUS.
To view the UE-to-IP address mappings, use the following CLI command:
show
ueip all
For this command, the source
(
src
) can be
pfcp
or
radius
, depending on the deployment
type.
To view other information about the UEIP database (such as timeout or the maximum
number of entries), use the following command:
show ueip info
To view the number of active unique IMSIs, use the following CLI command:
show ueip active-imsi
To change the timeout, use the following CLI command (where
value
is the number of minutes):
set ueip timeout <value>
For this command, the range is 1—1440 minutes and the
default value is 1440.
