A networked computer system is disclosed comprising database (or other) 5 applications accessible over a network to users via terminals in which at least some users have restricted access (restricted access privileges) to the applications. A security system is incorporated in the network and provides a functional layer between the user's environment and the database (or other) applications environment. The security system insulates the user's environment from the environment of applications being accessed so that connection information is not available to the user in a form that would permit the circumvention of access privileges.

DETAILED DESCRIPTION According to embodiments of the present invention, there is provided a security system for controlling access to data and/or one or more software processes, which security system comprises: i) input means for receiving user identification data from a user station; ii) means for authenticating received user identification data; iii) first data storage means for storing access restriction information in relation to the data and/or software process(es); iv) second data storage means for storing connect information for the data and/or software process(es); v) input means for receiving an identifier for selected data or software process(es); vi) translation means for translating a received identifier to connect information for locating the selected data or software process(es), using the second data storage means; vii) connection setup means for setting up a connection for providing access from the user station to the selected data or software process(es), using a translated identifier; and viii) disconnect means for disconnecting a link between the security system and the user station once said connection has been set up between the user station and the selected data or software process(es).
The term "user station" as used herein comprises the user's local environment; that is at least the user's terminal and potentially also the user's local server.
In general, the user station will comprise a platform on which the user's local processes run.
This could be for instance a personal computer alone, or a dumb terminal plus other platforms, potentially network-based.
Preferably, the connection setup means comprises means for transmitting connect information (a translated identifier) via the user station to the selected database or software process.
Preferably also, the connection setup means comprises encryption means for encrypting the connect information prior to transmission.
A security system according to an embodiment of the present invention constitutes a functional layer between a user station and one or more databases and/or software processes, such as a set of applications
