there was some high integrity mainframe systems deployed in the 60s and 70s. among other things, theyy were being used for commercial timesharing services ... some number of these commercial timesharing services were selling into the financial market ... where there is implicit requirement to safeguard customers from each other. http://www.garlic.com/~lynn/subtopic.html#timeshare note also that there was some amount of use in various gov. agencies based on similar criteria; a couple recent posts related to the subject. http://www.garlic.com/~lynn/2005k.html#30 Public disclosure of discovered vulnerabilities http://www.garlic.com/~lynn/2005k.html#35 Determining processor status without IPIs one scenario was at the cambridge science center http://www.garlic.com/~lynn/subtopic.html#545tech which was offering cms\apl services to business people in armonk corporate hdqtrs that had loaded the most sensitive of corporate secrets and were running various business modeling applications ... and concurrently there was access to the same system by students from various colleges and univs. in the boston area. we had a few cases of denial of service mounted by students that were quickly handled ... but i know of no data breaches. some of the DOS attacks that were attempted based on resource consumption. however, i had done dynamic adaptive resource scheduler as undergraduate in the 60s ... with the default policy being fair-share ... which tended to contain such efforts (and if they didn't, i had to find and fix any anomolies in the resource control implementation). the other DOS attacks used some structural characteristics that had to be quickly corrected. -- Anne & Lynn Wheeler | http://www.garlic.com/~lynn/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
