A system for identifying malicious messages transmitted over a mobile communication network includes: sentinel modules associated with respective mobile terminals in the network for monitoring messages passing therethrough, wherein the sentinel modules identify as a candidate malicious message, any message passing through the mobile terminals and failing to comply with a first set of patterns and issue a corresponding sentinel identification message; a set of probe modules for monitoring messages transmitted over the network, wherein the probe modules identify as a candidate malicious message any message transmitted over the network and failing to comply with a second set of patterns and issue a corresponding probe identification message; and preferably at least one client honeypot module for receiving and processing any messages sent thereto to produce corresponding processing results, wherein the client honeypot module identifies as a candidate malicious message any message producing a processing result failing to comply with a third set of patterns and issues a corresponding client honeypot identification message.

A honeypot system for protecting a mobile communication network against malware includes one or more user-less mobile devices including a monitoring module for monitoring the events conveying software applications in the associated mobile device as well as a controller client module that emulates human-like interaction with the user-less devices as a function of the events monitored. The system controllably performs, for the applications conveyed by the events monitored, one or more of the following steps: i) installing the application on the device; ii) executing the application installed on the device; and iii) de-installing the application from the device. After any of these steps, the state of the device is checked in order to detect if any anomalous variation has occurred in the state of the device indicative of the device being exposed to the risk of malware. If any anomalous variation is detected, the system issues a malware alert message.

A method of preventing intrusion in communication traffic with a set of machines in a network is provided, the traffic including communication entities, including the steps of: providing a test system comprising test facilities replicating at least one of the machines in the set; directing at least part of the communication entities in the traffic toward the test system; running the communication entities directed toward the test system on the test facilities to detect possibly adverse effects on the test system, and i) in the presence of an adverse effect, blocking, by the test system, the communication entities leading to the adverse effect, and ii) in the absence of an adverse effect, allowing, by the test system, the communication entities not having the adverse effect to communicate with the set of machines.

Method and system for intrusion prevention and deflection

Intrusions in a system under surveillance are detected by matching the events occurring during operation of the system against a knowledge base including information on events which occurred during a learning phase. The detection technique includes the steps of: recording, during the learning phase, temporal data related to the events during the learning phase; identifying, as a function of the temporal data recorded, a dynamic part of the knowledge base; discovering patterns that cover the dynamic part of the knowledge base; and using, during the analysis phase, a regular expression match at least with respect to the dynamic part of the knowledge base.
