Understanding SSID & Mac Address  SSID helps stations find APs around - 32 byte unique Service Set Identifier of AP - Like your company name on the building - Sent when AP receives a probe request from station - Can be seen in the air SSID  To deliver traffic, a unique Identifier must be available for each device – Media Access Control (MAC) Address  Example: a-03-3c-0f VendorOUI Cisco (Aironet) Agere (Orinoco) D Nokia00-e0-03 Linksys a OUI (Organizationally Unique Identifier, first 3 characters) Serial Number  Mac Address

Copyright © 2002 – 2004 AirDefense Proprietary and Confidential. Understanding Probes & Beacons PROBES:  A Station sends a probe request frame when it needs to obtain information from another station. (For example, a station would send a probe request to determine which access points are within range.) Probes User Station BEACONS:  The Access point (AP ) periodically sends a beacon frame to announce its presence and relay information, such as timestamp, SSID, and other parameters regarding the access point Access Point Beacons

Gartner on WLAN Security Risks 3 “Must Have” WLAN Security  Install a centrally managed personal firewall on laptops that are issued wireless NICs  Perform wireless intrusion detection to discover rogue access points, foreign devices connecting to corporate access points and accidental associations to nearby access points in use by other companies.  Turn on some form of encryption and authentication for supported WLAN use. July 31, “Must Have” WLAN Security  Install a centrally managed personal firewall on laptops that are issued wireless NICs  Perform wireless intrusion detection to discover rogue access points, foreign devices connecting to corporate access points and accidental associations to nearby access points in use by other companies.  Turn on some form of encryption and authentication for supported WLAN use.

Copyright © 2003 AirDefense Proprietary and Confidential Security Standards WEP: Wired Equivalent Privacy, a wireless encryption standard, which was developed by the IEEE standards committee X: IEEE standard for authentication, which supports multiple authentication modes, including RADIUS, that can be used in wireline and wireless networks. LEAP: Lightweight Extensible Authentication Protocol, which includes Cisco’s proprietary extensions to 802.1X to share authentication data between Cisco WLAN access points and the Cisco Secure Access Control Server. TKIP: Temporal Key Integrity Protocol, which was developed by the IEEE i standards committee as a WEP improvement. TTLS: Tunneled Transport Layered Security, which was developed by Funk Software and Certicom, now is an IETF draft standard. It is an alternative to PEAP. PEAP: Protected Extensible Authentication Protocol, which was developed by Microsoft, Cisco and RSA Security, is now an IETF draft standard. PEAP encrypts authentication data using a tunneling method. WPA: Wi-Fi Protected Access – Announced by the Wi-Fi Alliance to describe 802.1x with TKIP and MIC. Subset of the i security standard expected in Q4 ‘ i: IEEE standards group effort that involves fixing perceived weaknesses in 802.1X and WEP and creating an umbrella standard for security

Southeastern Hospital Rogue Incident #2 – Vendor With Hacking Software An unauthorized vendor came to sell to a department in hospital Obtained temporary access to WLAN from ED nodes for and internet Intercepted s from materials management staff in a matter of minutes Solution – identified rogue vendor as they passed through the hospital with AirDefense, had security meet them, and escorted off the building

Large Systems Integrator Case #1: Probing Vendor Vendor probing for WLAN within LM Aero controlled facility AirDefense alerted security officer via . Security resolved situation before any damage was done.

Large Systems Integrator Case #2: Mis-configured WLAN Approved WLAN with several configurations out of security specs AirDefense alerted security and network services Security and network services resolved problem.

Large Systems Integrator Case #3: Default Configuration Approved AP accidentally reset to factory defaults during construction in area of building AirDefense alerted security of default configuration. Security was able to shut AP down before any intrusions.

 As an educational institution we provide an open flexible network infrastructure  Many departments with network admins who want to install their own APs  Must maintain a standard configuration policy regardless of hardware used  Employees bringing in access points  Difficulty identifying WLAN performance issues A Large University Issues:

 Communication to staff, faculty, students – difficult at best  Create policy not allowing WLAN outside of ITS control – not good, people usually want and push for what they can’t have  War-walking – time consuming, doesn’t monitor 24-7 A Large University How Can the Issues Be Addressed?

 24/7 monitoring of airwaves  Security policy enforcement  A better view of our WLAN than EVER before  Time savings  Network management  Security  Product was purchased by security for security purposes – but the reality is that it’s been as much a WLAN performance & management tool A Large University 24 X 7 Monitoring with AirDefense
