Lawful Interception System, Dynamic user identification, Network event analysis, Administration and control of interceptions, Packet recording and classification
As a part of Sec6Net project, a Lawful Interception System was developed. This paper describes an extension of the system, which provides a capability to intercept application protocols (e.g. an e-mail communication) directly in a network of an Internet service provider. This new functionality enables to detect and filter out a related TCP transfer automatically. It is also able to handle situations, where the identity (an IP address) of a target user is not known yet, or when it is difficult to detect it (NAT is enabled, user is at an Internet café, etc.).
