LapTwo Technologies Brief / August 27, 2004 / two of four <br /> • The few Windows-based control systems in use were completely <br /> vulnerable to every new virus and worm infection appearing on the <br /> internet. <br /> • The non-Windows control systems were inflexible, offering little <br /> to nothing in terms of customizability or upgrade paths. They <br /> also suffered from vulnerabilities to viruses and worms (although <br /> such non-Windows attacks are rare at present) . <br /> Technologies Developed <br /> Significant technical breakthroughs and developments created in <br /> subsequent months have equipped the company with unique networking <br /> software development capacity and capabilities: <br /> • A method was devised to allow low-level networking software to be <br /> developed efficiently, in a user-friendly development tool. <br /> (Low-level networking software development using conventional <br /> methods, is easily among the most difficult, burdensome <br /> programming tasks in existence) . <br /> • A total replacement for all Windows Internet Networking (TCP-IP) <br /> software was designed and developed. (This completely eliminates <br /> the attack points used by viruses and worms to infect Windows <br /> • systems, while obviating the need for applying Microsoft security <br /> updates to patch such attack points) . <br /> • Made possible by the replacement TCP-IP software, several <br /> techniques for positively authenticating network traffic from <br /> validly-authorized system users were developed. (These <br /> techniques prevent the theft of internet connectivity by <br /> unauthorized users.) <br /> • Several techniques for isolating client computers from each other <br /> while they are connected to a common hospitality system were <br /> developed. (This prevents client computers having viruses from <br /> attacking other client computers while connected to the system.) <br /> • A technique for limiting the outbound email traffic sent by any <br /> one client computer was devised. (This protects the hospitality <br /> provider from inadvertently but illegally providing internet <br /> connectivity used to send mass-mail "spam" from the hospitality <br /> provider's internet connection.) <br /> Employing these breakthroughs, LapTwo is currently developing and <br /> refining a complete internet hospitality control system, planned for <br /> volume shipments in the fourth quarter of 2004. The common name for an <br /> establishment offering wireless public internet access is a "hotspot." <br /> • <br />
