That just makes the risks from unwiped temporary storage worse - all the bad guy has to do is grab the pen drive and walk off. Sure the computer will crash, but s/he now has 1GB of stuff to mine for 'interesting' data... Other problems are related to the basic reality of flash - which are: block vs. byte organization a limit on the number of read/write cycles (1M or 10M and poof, the chip is shot, as low as 1K for older models - which can be a problem for the FAT table). Lastly, there seems to be a capacity wall at 1GB (months after being promised, these are only now in very limited availability). -----Burton -----Original Message----- From: Carlos Manuel de La Concha Canedo [mailto:ofeyccc1 () prodigy net mx] Sent: Tuesday, August 02, 2005 12:08 AM To: security-basics () securityfocus com Subject: A question about USB Storage. Dear List Members, I have been reading threads recently about recovering temporary data such as swap file, temp files, et al. If the information in the swap file and other system temporal files its so important ¿why don´t put it in a usb device? With a usb capacity of about 4 GB it could be a solution (and an added complication) for the security of such files. It´s possible to do it? In windows? In linux? In Freebsd? I think that the sistem could include a function to erase the usb device at logoff or shutdown, besides, could you prove that A specific usb device was used in a specific computer? Thanks for your attention Ing.
