  1. Those ?! Portables CPIS 210 John Beckett

  2. Operating System • Palm OS • Microsoft • Windows CE • Windows Mobile / Pocket PC • Apple iOS • Android • Blackberry • Symbian • Kindle • Nook

  3. Net Connectivity • WiFi, WiMax • Special case: Airplanes that use satellites • Cell phone network • Bound to a carrier? • Monthly fee (or not: Kindle example) • Hard wire

  4. Blue Tooth • Local connectivity with devices • Device must be “bound” • Security tends to lag other devices

  5. Device Connectivity • USB • Portable is a device, looking like disk drive or accessible through host software such as iTunes • Portable is a controller, using external devices as memory (may not serve other functions) • Flash memory slot • Is there any “internal” memory? • How do “internal” and Flash memory relate to each other? • Video • Does it have a real “driver?”

  6. Battery Life • Smaller devices tend to have worst battery life • e.g. iPhone • Longer-lasting devices may take longer to charge • Common charging source: USB

  7. Challenges

  8. Ownership • Company owned: Any personal use by employee constitutes a taxable benefit and requires: • Accounting with objective basis such as time • Withholding of taxes and reporting on W-2 • Personally owned: Do you have a right to require them to maintain this “tool” for their job?

  9. Employee Time • Personal use subtracts directly from work time • Personal use destroys context, costing time both directly and indirectly (due to errors and context re-establishment) • Increasing availability of your employees to those you serve may increase your effectiveness

  10. Lost Device • Can you replace it quickly? • Hardware • Software • Data • Is your data protected?

  11. Information Leakage • Data may be leaving your site in the portable’s memory • The portable might be beaming data off-site • Employee may be using the portable instead of designated functions (e.g. calendar, notes) • Data might fall in the wrong hands • Data might get lost and you could not prevent it

  12. Summary • Portables are here to stay • Portables are subject to constant “churn” • Control issues become more difficult with portables • Support becomes more challenging because you have more types of portables

  13. Answers – Lost Device • Keep data on a central server • Key fob to alert when left behind

  14. Ownership • Give to employee • Report as taxable income • Allow personal use • Require availability for work

  15. Corporate Net Security • Main server pushes settings to client devices (require controlled devices) • Separately firewalled wireless net for portables – assume some hostility
