Information on the identity of each user connecting via a wireless device is obtained using a prior process of authentication and context information and/or the status of the user; a characteristics vector is generated for each user, which comprises the context information and/or the user status and a user profile. Permissions are assigned to each user, determining the type of secured network resources each user is permitted to access, depending on their characteristics vector; and a secured-network-resource access check is performed, enabling the transfer of data only to/from resources permitted for each user, as a function of the permissions assigned.
