Software execution control in which a series of two-way rule checks is performed between software-defined communications system component records to ensure and maintain system security and integrity. A system platform (20) performs a series of two-way rule checks between records of a system platform (20) and an application (22) called by the platform (20), between records of the called application (22) and a module (24) that defines the called application (22), and between the records of the module (24) that defines the called application (22) and the platform (20). Both the called application (22) and the module (24) that defines the called application (22) are then instantiated if the two-way rule checks are successful. Because the rule checks are performed in a two-way manner, restrictions such as licensing and source restrictions may be placed not only on system modules (24-30), but also on the applications (22) using the modules (24-30), thereby enabling higher levels of system security to be achieved. In addition, the present invention minimizes processing overhead by providing for load-time rule checking rather than run-time checking associated with conventional enforcement systems.

L'invention concerne une commande d'exécution de logiciel, dans laquelle une série de vérifications bilatérales est effectuée entre des enregistrements de composants de systèmes de communications définis par logiciel pour assurer et maintenir la sécurité et l'intégrité du système. Une plate-forme système (20) exécute une série de vérifications bilatérales entre des enregistrements d'une plate-forme système (20) et une application (22) appelée par la plate-forme (20), entre les enregistrements de l'application (22) appelée et un module (24) qui définit lesdites application (22) et plate-forme (20). L'application (22) appelée et le module (24) qui la (22) définit sont alors instanciés dans le cas où les vérifications bilatérales sont réussies. Ces vérifications étant effectuées de manière bilatérale, des restrictions, notamment au niveau des autorisations et des sources, peuvent être imposées non seulement aux modules de système (24-30), mais aussi aux applications (22) utilisant ces modules (24-30). Ainsi, des niveaux de sécurité du système plus élevés peuvent être réalisés. L'invention permet en outre de réduire la surcharge de traitement par la vérification du temps de charge, plutôt que par la vérification de la durée d'exécution liée aux systèmes d'exécution classiques.
