ADSL Lines

A sophisticated tactical system for recording and analysis, which can be used on its own or in conjunction with SIC to intercept ADSL. It enables on-the-spot recording, decoding, evaluation and visualisation with the SDA for ISP with optional support for analysis using a free text search tool. Alternatively the raw data can be routed to the SYBORG Interception Centre (SIC).

ATM Recorder

The ATM Recorder serves to intercept Internet activity directly at the Internet Service Provider, or to capture data directly within the networks. The data for the target facility (usually DSL) are recorded in the ATM network of the provider and routed straight to the input interface of the ATM recorder. All data are saved in a default directory and are then accessible for further processing. The data can be decoded on the spot and analysed immediately when combined with the SYBORG Data Analyzer, or can be transmitted to the SYBORG Interception Centre for further processing.

High-speed Modem Connections

Our solution for intercepting high-speed modem connections autonomously distinguishes between active tapping—for high-speed modem connections—and passive tapping—for conventional voice and data connections. Captured data are saved in interim storage and transmitted to the SYBORG Interception Centre (SIC) via an ISDN or IP connection for further processing or to an autonomous system for recording and analysis with the appropriate interface. Alternatively, we also offer a fully integrated system that includes the SYBORG Data Analyzer for decoding the data using a graphic user interface for the analysis.

Passive IP Tapping (IP Probe)

The IP Probe system for intercepting broadband traffic can intercept up to 9 lines with data rates up to 1 GBit / sec (also optical) with one single IP Probe, without any loss of packets. The filter algorithms only process the relevant traffic. Thanks to integrated decoding and routing it is possible to carry out recording and further processing in any monitoring centre that conforms to ETSI (e.g. SIC from SYBORG). Flexible interception criteria enable the probe to be used in almost any broadband network for the interception of:

• IP addresses
• URLs and host names
• VoIP
• email (addresses or user name in SMTP, POP3, IMAP4)
• Webmail
• Chat and Instant Messaging (IRC, MSN, Yahoo, ICQ, FTP, Telnet, News)

All the filter criteria can be set on the spot and become active immediately.

ISDN BRI lines

A passive ISDN tap is employed here with a recording functionality. Voice and data communications (e.g. Internet via ISDN) as well as signalling information are recorded, saved in interim storage and forwarded over an IP line to the SYBORG Interception Centre or an autonomous system for recording and analysis with an appropriate interface.

SIR

Intercepting telecommunications in businesses or hotels entails both legal and technical problems as only one target needs to be intercepted. Since the typical solution is overall interception of one PRI line, technical implementation involves considerable effort and is often not feasible on legal grounds.

With the SIR (SYBORG ISDN Recorder) it is now possible to record on one ISDN PRI line (30 B channels) directly and to filter according to specific numbers. This method ensures that only communications for the target facility are recorded (e.g. in a hotel room). This drastically decreases the technical outlay needed to carry out the interception measure and ensures that the recording is target-centric, which simplifies enforcement of court orders for interception meaures like this.

The SIR consists of a portable PC, which is connected passively to an ISDN line and records all telephone calls for the specified phone numbers. The SIR also has a facility for listening to calls directly and can duplicate the calls to another telephone line - so the investigator can if necessary move around freely with his mobile phone and can also listen in to any telecommunications even when in the vicinity of the target. This makes it possible for surveillance teams to take action within a minimum of time.

The SIR can also be equipped with the additional SDA software (SYBORG Data Analyzer), which makes it possible to decode and view fax, modem and Internet sessions in the SIR directly. The recorded communications can of course also be transmitted to the Syborg Interception Centre for further processing.
