Small physical size More durable Fast Speed --3MB/s Big capacity Low price More functionality Plug-and-Play -1million read & write cycle Why Choose USB ?Why Choose USB ? 6. Greatest benefit = Greatest security risk !Greatest benefit = Greatest security risk ! 7. 85million units sold in 2007 Only few buyers thought about the drives security implications. -Gartner 8. According to security firm Vontu >50% of 480 surveyed tech- professionals USB drives contain unprotected confidential information 1 USB drive is lost at work each month Unlike laptop, storage devices are small and cheap. Many employees do not report them missing as they would a laptop. 9. Corruption of data Virus Transmissions Loss of media Loss of confidentiality RisksRisks 10. Corruption of data Occur if the drive is uncleanly dismounted computer usually has no way of knowing when USB memory sticks are going to be removed The OS will attempt to handle unexpected disconnects as best it can, so often no corruption will occur. RisksRisks 11.
