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).
