STAR-GATE for PACKET DATA

Introducing STAR-GATE, a comprehensive solution for GPRS and 3G networks, offering functional descriptions, product demonstrations, and ISP solutions. The architecture supports multiple networks and switches, and the mediation device performs communication surveillance. The solution covers administrative and delivery functions, and supports a wide range of protocols for flexible application design. With the STAR-GATE SAS system, targets are assigned and system administration, maintenance, and security are overseen. The solution also includes interception criteria, delivery formats, and synchronization of target lists.

  15. WELCOME TO STAR-GATE DEMO

  16. STAR-GATE SOLUTION for ISP

  17. STAR-GATE for ISP - Challenges • Operational challenges: • Target Provisioning • Identification of target traffic • Control and maintenance • High Security • Technological challenges: • Various network topologies • Fast changing architecture • No interference with ISP Service level

  18. STAR-GATE for ISP - Solution • Interception Criteria: • E-mail address • Username/CLI in RADIUS • IP address • MAC address • Access Solution based on: • LAN Splitter for mirroring • Switching hubs for aggregation and filtering • PD MD Software

  19. STAR-GATE for ISP - Solution • Delivery Method: • FTP • Stream based • Delivery Format: • TIIT • STAR-GATE Tunneling Protocol

  20. ISP Mediation Device S/W Design Network Access (Interceptor) Access Device Core Logic MD HI1 HI2 HI3 MD Inside

  21. Interceptors • RIPE (RADIUS IP Extractor) • Keeps in RAM the target list (Username/CLI) • Monitors RADIUS messages • Generates HI2 messages to LEMF • Activates 3-4 layer switch and IPI based on extracted IP address • Stops 3-4 layer switch and IPI upon logout event

  22. Interceptors • IPI (IP Interceptor) • Gets IP address from RIPE • Analyze each packet in real-time • Collects packets • Forwards to LEMF

  23. Interceptors • SMTPI (SMTP Interceptor) • Keeps in RAM the target list (E-mail address) • Monitors SMTP (Port # 25) • Checks E-mail address in “RCPT TO” or “MAIL FROM” • Buffers all E-mail (from DATA command to closing ‘.’) • Forwards LEMF

  24. Interceptors • DHCPE (DHCP Extractor) • Keeps in RAM the target list (MAC address) • Monitors DHCP • Identifies events of IP address assignment • Generates HI2 messages to LEMF • Updates the system with the new IP address

  29. The Access Device

  30. Solution Considerations • Coverage • Intercepting all targets • Intercepting all data • Minimize number of intercepted links • Target Identification • RADIUS • DHCP • Security • None intrusive • Encryption

  31. The Solution

  32. System Security • Access rights: Access to target activation and database is controlled by user rights. • Audit Trail: For user login/logout and target activation/deactivation activities. • Centralized Target List Architecture: GSA is the only LI entity where target list is saved on disk • Passive interception: No indication for on going interception • Encrypted delivery to LEAs: Delivery to LEAs can be encrypted using IP-Sec or TLS.

  33. WHY STAR-GATE • Comprehensive Solution • Any Network • Any Switch • Any Protocol • Unified Administration Center • Open Design and Flexible Architecture
