  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

  34. Thank you
