    • 3. Part One Overview of Wireless Data Network Technology
    • 4. Wireless Network Access
    • 5. Wireless 101 (part 1) <ul><li>Wave characteristics </li></ul><ul><ul><li>Wavelength - The distance traveled in one cycle in meters, centimeters, etc. </li></ul></ul><ul><ul><li>Frequency - The number of cycles repeated during a unit of time (usually 1 second) is the frequency, usually expressed as hertz (cycles per second). </li></ul></ul><ul><ul><ul><li>Wavelength and frequency are inversely proportional. </li></ul></ul></ul><ul><ul><ul><li>As frequency increases, potential data throughput increases, but signal propagation decreases. Typically 2 Ghz and up are used for data apps. </li></ul></ul></ul><ul><ul><li>Amplitude – Maximum displacement of the wave from zero </li></ul></ul><ul><ul><li>Phase - The phase of a wave is the amount by which the cycle has progressed from a specified origin, usually expressed in degrees of a circle, and relative to that of some other wave. For example, two waves having crests 1/4 cycle apart are said to be 90° “out of phase.” </li></ul></ul><ul><ul><li>Reflection </li></ul></ul><ul><ul><li>Refraction </li></ul></ul>
    • 6. Wireless 101 (part 2) <ul><li>Spectral efficiency </li></ul><ul><ul><li>The amount of data (bits per second) carried on one hertz (cycle per second) of bandwidth; varies with encoding (modulation) techniques. </li></ul></ul><ul><li>Licensed versus Unlicensed </li></ul><ul><ul><li>Licensed frequencies generally have exclusive use and in general allow for much higher transmit power than unlicensed frequencies. </li></ul></ul><ul><ul><ul><li>For example. maximum transmit power allowed for AM radio is 50 thousand watts, for a WiFi access point is1watt. </li></ul></ul></ul><ul><ul><ul><li>Minimum receive power is also important, determined by a number of factors such as encoding/decoding scheme and hardware, antennas. Can be as low as 1 pico-watt (trillionth of a watt) </li></ul></ul></ul><ul><ul><li>The new 4.9Ghz Public Safety band is an exception in that it is shared among Public Safety entities and has maximum transmit power closer to many unlicensed band. </li></ul></ul>
    • 7. Wireless Data: What’s Important? <ul><li>Range </li></ul><ul><li>Throughput </li></ul><ul><li>Cost </li></ul><ul><li>Security </li></ul>
    • 8. Wireless Broadband Data <ul><li>Broadband Wireless Data: </li></ul><ul><ul><li>Any wireless communication with transmission rates greater than 256 kbps </li></ul></ul><ul><ul><li>No single technology will become dominant or ubiquitous; they all meet unique user requirements in a wirelessly connected world. </li></ul></ul><ul><ul><li>The best wireless solutions (systems) may involve a combination of technologies to allow increased mobility (and ultimately seamless roaming) </li></ul></ul>

    • 18. Radio Waves and Safety What Are the Risks? “ It was found that users who spend more than an hour a day talking on a mobile phone have a close to one-third higher risk of developing a rare form of brain tumor. Most frequently, the cancers were found on the side of the head that the user held the phone up to. ” International Journal of Oncology, February 2003;22(2):399-407 &quot;There is currently insufficient scientific basis for concluding either that wireless communication technologies are safe or that they pose a risk to millions of users.... FCC radio frequency radiation guidelines are based on protection from acute injury from thermal effects of RFR exposure and may not be protective against any non-thermal effects of chronic exposures.&quot; U.S. Food and Drug Administration, February 2000 NYSTEC has been studying this issue with the US Air Force at Rome Labs

    • 31. Part Three Organizational Risks Associated With Mobile Computing
    • 32. Mobile Devices are Easy Targets! <ul><li>PDAs and Smartphones are small and easy to lose: </li></ul><ul><ul><li>24% of US business professionals experienced loss or theft of at least one PDA (Pepperdine) </li></ul></ul><ul><li>In recent years Smartphones have gone from embedded CPU-specific microcode to full featured multi-services Operating Systems </li></ul><ul><li>Users are not as wary as they are using PCs and laptops </li></ul><ul><li>There are many network-borne infections and exploits: </li></ul><ul><ul><li>There have been hundreds of mobile viruses and worms since June 2004. Infection vectors include Bluetooth, MMS (SMS), OS API’s, OS vulnerabilities, email </li></ul></ul><ul><ul><li>Mobile users frequently install unknown code </li></ul></ul>
    • 33. Mobile Devices Present Unique Challenges <ul><li>Windows laptop security programs may not run “as-is” on stripped down Windows Mobile 5.0 for Pocket PC and Windows Mobile 6 Classic </li></ul><ul><li>Wireless creates new data network attack opportunities… </li></ul><ul><ul><li>Many PDAs and Smartphones have 3+ wireless services (cellular, Wi-Fi, Bluetooth) </li></ul></ul><ul><li>The default security mechanisms in mobile devices are turned off (for ease of use) </li></ul><ul><li>Many users use these devices without the knowledge of IT Departments </li></ul><ul><ul><li>Forward email and/or store calendar information (synch with PC using products like BitPIM) </li></ul></ul><ul><ul><li>Use as an external storage device </li></ul></ul><ul><li>http://www.flexispy.com (“Download FlexiSPY spyphone software directly onto a mobile phone and receive copies of SMS, Call Logs, Emails, Locations and listen to conversations within minutes of purchase” ) </li></ul>
    • 34. Organizational Risk <ul><li>Theft of organizational data off the device. This can lead to non-compliance issues-- HIPAA, State Disclosure Laws (for example, NYS Information and Security Breach Notification Act, CSCIC Policies, Federal Policies ) </li></ul><ul><li>Theft of data when the device is transmitting/ receiving data </li></ul><ul><li>Loss of organizational data off the device. Think of the cost (i.e., amount of time it would take to replace the data) if the data is lost or corrupted. This data includes phone book and calendar information. </li></ul>
    • 35. Organizational Risk <ul><li>The device is extending the organizational network, when the device interacts with the corporate infrastructure: </li></ul><ul><ul><li>End point on the network (wireless LAN, VPN) </li></ul></ul><ul><ul><li>Synching with a PC (cabled or Bluetooth) </li></ul></ul><ul><ul><li>Accessing corporate applications </li></ul></ul><ul><ul><li>Accessing corporate email servers </li></ul></ul><ul><ul><li>Acting as a VPN end point </li></ul></ul><ul><ul><li>This can pose several risks to the organizational infrastructure: </li></ul></ul><ul><ul><li>Malware </li></ul></ul><ul><ul><li>Network Compromise </li></ul></ul><ul><ul><li>Password compromise </li></ul></ul><ul><ul><ul><li>SMS phishing attacks seen in August 2004 </li></ul></ul></ul><ul><ul><ul><li>Email, VPN, Internet facing applications </li></ul></ul></ul>
    • 36. Part Four Encryption Options
    • 37. Securing Data in Transit <ul><li>Just like other data networks, mobile data needs to be secured during transmission </li></ul><ul><li>Even if the device’s data is encrypted “over-the-air” (OTR), it may not be encrypted end-to-end </li></ul><ul><li>Flaws have been found in GSM and CDMA authentication and encryption algorithms and carriers may not implement all controls </li></ul><ul><li>As with wired networks, there are various alternatives for securing mobile data in transit: </li></ul><ul><ul><li>Using Secure Socket Layer (SSL) protocol over a secure Web connection </li></ul></ul><ul><ul><li>Using Virtual Private Network (VPN) solutions </li></ul></ul><ul><ul><li>Using end-to-end secure mail protocols like S/MIME, PGP </li></ul></ul><ul><ul><li>Using SMS/MMS filters to block unsolicited spam, phishing </li></ul></ul>
    • 38. SSL VPNs <ul><li>SSL VPNs are a good option for mobile devices that have a browser to support them. </li></ul><ul><li>SSL VPNs are fairly open solutions, requiring less configuration and management on the client side, but more configuration on the server side. </li></ul><ul><li>SSL VPNs support multiple modes of operation: </li></ul><ul><ul><li>Basic Browser access </li></ul></ul><ul><ul><li>Port forwarding </li></ul></ul><ul><ul><li>Client-based tunneling </li></ul></ul><ul><li>The mode of operation has an impact on the client dependencies and applications (must ensure that the chosen mode supports your target applications) </li></ul>
    • 39. Mobile VPNs <ul><li>Mobile VPNs extend data protection by encrypting traffic between the mobile device and a VPN gateway at the edge of the LAN. </li></ul><ul><li>Mobile VPNs are more proprietary solutions that require installation and management on the mobile device. </li></ul><ul><li>Smartphones and vehicle-mounted laptops roam among WLANs and/or cellular network “dead spots” that often cause breaks in IPSEC tunnel connectivity </li></ul><ul><li>Smartphones may also “go to sleep” that would interrupt IPSEC and SSL based VPN sessions </li></ul><ul><li>To stay connected, mobile VPNs rely on client software and specialized VPN gateways: </li></ul><ul><ul><li>Create a “persistent session” that will spoof client-server connectivity in order to hold a session open during loss of signal, etc. </li></ul></ul>
    • 40. Built-in Mobile VPNs <ul><li>Many mobile Operating Systems include VPN clients: </li></ul><ul><ul><li>Palm OS 6: PPTP supplied with Wi-Fi card </li></ul></ul><ul><ul><li>Windows Mobile 5.0: PPTP, L2TP over IPsec </li></ul></ul><ul><ul><li>Blackberry: proprietary OTA encryption </li></ul></ul><ul><li>Concerns: </li></ul><ul><ul><li>Traffic (processing) overhead </li></ul></ul><ul><ul><li>Compatibility with existing agency VPN </li></ul></ul><ul><ul><li>Inter-network roaming </li></ul></ul>
    • 41. Part Five Security of Data on the Mobile Device
    • 42. Protect Data at Rest <ul><li>Encryption is the most effective (only?) way to protect data stored on the mobile device </li></ul><ul><li>Many laptop encryption vendors offer solutions for mobile Operating Systems. </li></ul><ul><li>Encryption should extend to the files on the storage media used in the mobile device </li></ul><ul><li>Encryption solutions should be flexible and include support for standard encryption algorithms (for example AES) with 128 bit, 192 bit, and 256 bit encryption keys. </li></ul><ul><li>There is a relationship between the strength of the encryption key and power consumption… </li></ul><ul><ul><li>The more powerful the key, the more it reduces battery life </li></ul></ul>
    • 43. Recommendations for Mobile Data Device Data Encryption <ul><li>Will need to ensure that the data encryption method chosen meets security policies, but does not over tax CPU, memory and battery resources </li></ul><ul><li>Want to select the minimum encryption necessary to comply with the security policy and the sensitivity of the data (See NIST SP 800-57) </li></ul><ul><li>Use solutions that encrypt “in place” rather than containers that require the user to save files in folders (which creates an opportunity for abuse and user error) </li></ul><ul><li>Certified products that conform to FIPS 140-2 requirements ensure that data protection meets robust federal requirements </li></ul><ul><li>Access Control and key management are essential for encryption to be effective </li></ul>
    • 44. Part Six User Identity and Access Management
    • 45. Access Control: Is It Used? <ul><li>Access Control issues </li></ul><ul><ul><li>Access to data on device </li></ul></ul><ul><ul><li>Access to applications and data on back-end systems </li></ul></ul><ul><ul><li>Access to carrier network (device access). This cannot be relied upon to authenticate user. </li></ul></ul><ul><ul><li>Allow/prohibit features or applications on the device </li></ul></ul><ul><li>Many mobile device Operating Systems include access control mechanisms… </li></ul><ul><ul><li>But they need to be enabled (and often are not) </li></ul></ul><ul><ul><li>May be inconvenient for the user </li></ul></ul><ul><ul><li>May not be enforced by the organization </li></ul></ul><ul><li>Access control must be used in conjunction with encryption to protect data on the device. </li></ul>
