A method for detecting if an online review written by a user on a website of a telecommunications network is a spam, using at least one previously-labeled review, a review dataset comprising at least one review to be analyzed, and a spam feature list listing different features of spam reviews, method wherein:a) a weight is computed for each spam feature of the spam feature list, corresponding to the importance of the spam feature in the detection of spam reviews, and based at least on the features of said at least one previously-labeled review, andb) a probability of being a spam for a review under analysis in the review dataset is computed by using at least the weights of the spam features computed at step a) and a comparison between the features of said review under analysis and the ones of at least one review previously-labeled as spam.

A method of selecting, for at least one service of an information system and depending service(s), at least one countermeasure to be implemented against at least one cyber attack, the method comprising:- identifying elements of the service exposed to the cyber attack(s),- calculating a risk mitigation level of each countermeasure with respect to the cyber attack(s),- ranking the countermeasure(s) on the basis of a parameter which is at least a function of the risk mitigation level,simulating the impact of the countermeasure(s) on the service and the depending service(s), the countermeasure to be implemented being selected at least as a function of result of the simulation.

System for testing a protocol, which is active on an item of equipment, testing system including a monitor to continuously capture traces, corresponding to sequences of messages of protocol under test, a filter of the traces captured using formalized properties of the demands of protocol under test, to separate the traces into data and control parts, a temporary storage, and transfer module to transfer the filtered traces to a tester so as to emit verdicts by verifying whether the traces satisfy the demands of the formalized properties of the protocol under test, in the event of saturation of the tester leading to the emission of a notification of load, the transfer module interrupts the transfer of filtered traces to the tester and stores the traces at least partially in the temporary storage, particularly only their control parts, before resuming the transfer of filtered traces when the tester is again available.

A method for allocating resources in a distributed cloud computing including a plurality (N) of interconnected datacenters (V) for performing a user task requiring a plurality (NVM) of virtual machines (VM), the method comprising:a) generating a plurality of sets (F) of datacenters, each set (F_(n)) comprising a different respective first datacenter (V) and one or several additional datacenters, the additional datacenter(s) being iteratively selected among datacenter candidates (V_(i)) chosen among not-yet selected datacenters of said plurality of datacenters, until covering the needs in virtual machines (NVM) for performing the user task, at least by comparing communication cost values (C_(i)) computed for each datacenter candidate (V_(i)) based at least on the communication cost (g) from already-selected datacenter(s) of the set (F_(n)) to the current candidate (V_(i)) and on an estimated communication cost (h) induced by adding the remaining datacenters needed after selecting the current datacenter candidate, andb) selecting a set (F_(B)) of datacenters (V) for performing the user task based at least on a comparison of the total communication costs of the sets (F) of datacenters generated at step a).
