Access method and device for securing access to information system

摘要

The invention relates to a method and an access device for securing logical access to information and/or computing resources in a group of computer equipment while slowing down logical access as little as possible. The group of computer equipment exchanges data with a computer telecommunication network, via said access device. The data include transported data that conform to at least one application protocol, as well as transport data. The access device comprises an operating system that includes an appropriate analysis module for each applicative protocol, filtering means for filtering said transported data in said operating system, by means of said analysis modules.
