Abstract: A method and device for configuring a firewall in a computer system employing a rule for controlling access between a source resource and a destination resource only if said source and destination resources belong to the same protection domain. At a central configuration machine, an access control rule is specified, including a scope, for each resource group, the scope, and thus the access control rule is capable of being interpreted by each of the plurality of firewalls differently depending on the value of the scope and network resource characteristics associated with each of the plurality of firewalls.

Abstract: The invention relates to a method for optimizing the looking up of a page (200) of data looked-up on a terminal (100) by at least one user. The looked-up data are downloaded from a first remote site (103, 104, 105) and/or are available on a data medium. The method comprises a step for inserting (302, 402) on the fly at least one active code into the page (200) by means of a terminal (100).

Abstract: A consultation optimization method for a data page (200), consulted on at least one terminal (100) by at least one user. The page (200) is downloaded from a remote site (103; 104; 105; 106) via a communication network. The method comprising an on-the-fly insertion step (302; 402) of at least one active code (201) enabling the execution of a corresponding algorithm in the page (200) by at least one component (101; 102) of the network architecture.
