  1. Security Enhancement For An Infrastructure Wireless Domain Ganesan S/O Muniandy August 2003

  2. Agenda & Objective • Wireless LAN • Understand and Address Wireless Domain Security Issues • Protection and Security Enhancement

  3. Introduction - Background • Background • Exist since 1996 • Slow Growth Rate • Doubt about security and performance • Minimum Setup: • Access Points • Wireless Interface Card • Basic Network Setup – Ad hoc and Infrastructure

  4. Security Concerns • Hottest issues found today is concerning securities • More hacking tools are available in the internet • Hacking issues concerning • Theft of information • Illegal access • Method of hacking • Policy violations • Identity theft (SSID and MAC address) • Man in middle attack • Denial of service -DOS

  5. Research On Security - Survey

  6. Research On Security - Survey

  7. Research On Security - Survey

  8. Customer Requirement – (Case Study) • Low cost implementation • Reliable and flexible solution • Manageability • Expandability

  9. Existing Infrastructure (Case Study)

  10. Existing Wireless Connection Flow Wireless LAN NetID 1 Private LAN NetID 1 - User Authentication - Same Network ID

  11. Proposed Solution Wireless Connection Flow Wireless LAN Netid 1 Act as Firewall and VPN Gateway Wireless LAN Netid 3 Server VPN Tunnel Private LAN Netid 2 SSH & WWW Server Remote Site

  12. Proposed Solution – Diagram (Case Study)

  13. Proposed Solution - Details • A server act as firewall and VPN gateway: • Block port level • Divide network into 2 portion • Configurable to allow specific protocol • SSH, WWW or Others • Secure VPN Tunnelling

  14. Comparison with other products

  15. System Requirement • Minimum Hardware Requirement • CPU: 300MHz • Memory: 128MB • Hard disk: 2GB • NIC: 2 • CDRom: 1 • Floppy: 1

  16. Conclusion • Suitable for SMI (Small Medium Industries) • Low cost of Implementation and Security • Manageability
