  • WLAN Benefits
    • Easy Installation.
    • Wide Range of Covering.
    • Economical.
    • High transfer rate.
    Dept of CSE, DSCE 2010
  • WLAN Standards
    • IEEE 802.11b
    • IEEE 802.11a
    • IEEE 802.11g
    Dept of CSE, DSCE 2010
  • The Three Feathers of WLAN
    • The Openness of WLAN.
    • The Mobility of Node.
    • The Instability of Signal.
    Dept of CSE, DSCE 2010
  • Security Threats
    • AP Unauthorized Access.
    • Information Eavesdropping.
    • Signal Interference.
    • Denial of service.
    Dept of CSE, DSCE 2010
  • Existing Security Technologies
    • SSID.
    • MAC Filtering.
    • WEP.
    Dept of CSE, DSCE 2010
  • New Security Control Program Proposed
    • Access Control.
    • Content Filtering.
    • Data Encryption.
    • User Management.
    • Log Audit.
    Dept of CSE, DSCE 2010
  • Access Control
    • VP N :Replace existing WEP protocol Solutions.
    • Port Access Control[802.1x]
    Dept of CSE, DSCE 2010
  • Content Filtering
    • Use Software Filters.
    • Use Hardware Filters.
    Dept of CSE, DSCE 2010
  • Data Encryption
    • Include larger strength Encryption technologies.
    • Replace Existing WEP by WPA.
    Dept of CSE, DSCE 2010
  • User Management
    • Use of different Grades with different permission levels.
    • Prohibit installing unauthorized AP.
    Dept of CSE, DSCE 2010
  • Log Audit
    • Audit log file.
    • Store messages about software, services, operating system or hardware devices.
    Dept of CSE, DSCE 2010
  • Conclusion
    • Access control, content filtering, data encryption, user mgmt. & several other aspects, expected to provide some help with the construction of Digital Campus Network.
    • WLAN will play a more important role in colleges because of its high speed transmission capacity & flexibility.
