A security and protection device () for protection of the data and executable codes of any fixed or portable computer system and that has a memory medium to be protected. The security and protection device () is located physically between the computer system () and the memory medium (MP) to be protected, in order to allow the computer system () access to the data and codes to be protected after execution of the protection functions independently of the machine code executed by the computer system () and requires no interaction with the processor of the system for the execution of these functions.

Device for protection of the data and executable codes of a computer system

A client application () establishes in a client network (), a first connection having a first security level, directly with a first port () of a server application () hosted in a server machine () linked to a server network (), in order to send messages addressed to the server machine (). The messages pass from the client network () to the server network () through a network layer (CR) of a gateway machine (). In the gateway machine, a secure application proxy reroutes the messages from the first connection, in a way that is transparent for the client application, and establishes a second connection having a second security level with the server application; the second connection is unknown to the client application.

Secure multiapplication proxy

A network communications method communicates a certificate from a client machine to a server machine through a security module. The protocol used between the client and server machines is HTTP or an equivalent protocol, and a security protocol such as SSL or an equivalent is implemented between the client machine and the security module. The steps of the method include inserting the certificate into a cookie header of a request in HTTP or an equivalent protocol, and then transmitting the request from the security module to the server machine.
