Abstract

A method and a device for managing a computer network, especially a technique for ensuring the security of a network. A computer network system in which computers are connected to each other through transmission lines, each computer stores the data which constitutes a moving type software exclusively used for security and transmitted together with a message when the computer transmits the message to another computer of the system, and executes the moving type software by using the stored data upon receiving a message from another computer.

Claims

1. A computer network system including a plurality of computers, each including communication means for communicating, comprising:

a first computer, said first computer comprising means for transmitting moving type security software held by said first computer to one of said plurality of computers;

a second computer, said second computer comprising fixed type security software, the fixed type security software including;

means for receiving said moving type security software from said first computer,

means for storing said moving type security software,

means for executing said moving type security software,

means for creating a copy of said moving type security software, and

means for transmitting the created copy of the moving type security software to one of said plurality of computers; and

a third computer comprising said fixed type security software, the fixed type security software including;

means for receiving said moving type security software from said second computer,

means for storing said moving type security software,

means for executing said moving type security software, and

means for creating a copy of said moving type security software; and

wherein the moving type security software secures the safety of at least one of said second and third computers.
