The Features of Lawful Interception
The complete LI system is tightly integrated with Radiator
and provides RADIUS-based triggering, traffic interception, mediation
and warrant management in a highly scalable and secure design.
Triggering Zone
Radiator RADIUS server(s) monitor and scan all requests for the authentication
of a target service. This triggers the interception and collection of
session related data. Username, calling line identifier (CLID), IP address
or other RADIUS attributes can be used to identify a target service.
Traffic Interceptors
Traffic Interceptors like sniffers and probes, filter and capture packets
from an Ethernet network. They are able to acquire target traffic from
within a 10/100BaseT or Gigabit Ethernet connection. Able to be installed
in geographically disperse locations (remote and local pops), target IP
content is captured, cached, and forwarded to a central Mediation Platform.
Mediation Platform
Regulating the workflow of the entire system, the Mediation Platform executes
a Warrant exactly within its parameters. Controlling the activities of
Radiator and the Traffic Interceptors, captured target content is stored,
formatted, encrypted and automatically forwarded to the appropriate LEA
within minutes of acquisition. The mediation also provides the Warrant
Management Application that is used to manage the warrants that it serves.
Warrant Management Services
Providing a fully functional secure web site, users and administrators
can easily manage and monitor Warrants, logs and the other components
of the LI solution.
Scalability
Modular by design and built using Java and C++, the LI solution easily
scales. The software is designed to operate on the BSD, Solaris, OSX and
Linux operating systems.
Security
Multiple layers of security are implemented to protect sensitive management
and intercepted information. All servers and components are strengthened
against attack and can only be accessed by authorised staff using secure
communications protocols.
All maintenance user activities are fully logged and controlled. Audit
trails are designed to meet the harshest investigations and can only be
accessed upon request. All sensitive data is encrypted and target service
content is only stored for the time needed to transfer it to an LEA monitoring
centre.
