Internet Access Interception

For the surveillance of Internet access there is generally a choice between active and passive interception methods. With active interception available network elements like routers (typically edge routers) and AAA servers provide capabilities to filter access information and content of the communication of a person under surveillance. Passive methods on the other hand rely on additional filters (probes) that are integrated into the operator’s network to passively intercept all relevant data independent of the commercial services. In some cases a combination of active and passive methods provide the best results or is the only solution feasible.
Utimaco LIMS™ supports a large variety of active and passive interception access points and can be flexibly adapted to individual network configurations and regulatory demands.
