A system for enforcing security policies on mobile communications devices is adapted to be used in a mobile communications network in operative association with a subscriber identity module. The system having a client-server architecture includes a server operated by a mobile communications network operator and a client resident on a mobile communications device on which security policies are to be enforced. The server is adapted to determine security policies to be applied on said mobile communications device, and to send thereto a security policy to be applied. The client is adapted to receive the security policy to be applied from the server, and to apply the received security policy. The server includes a server authentication function adapted to authenticate the security policy to be sent to the mobile communications device; the client is further adapted to assess authenticity of the security policy received from the server by exploiting a client authentication function resident on the subscriber identity module.

A method for protecting sensitive data in an entry of a log file for later audit, which includes encrypting the sensitive data in the log entry by using a random cryptographic key for each auditor authorized to access the log entry, encrypting the random cryptographic key by using an auditor's personal cryptographic key, and for each auditor not authorized to access the log entry, encrypting a fake cryptographic key having the same properties as the random cryptographic key by using an auditor's personal cryptographic key.
