A method for constructing behavioral software signatures. The method includes: embedding execution traces of a set of software in a vector space, an execution trace of a software agent including at least one event and being representative of the execution of the software, the embedding representing an event of the execution trace by a vector encoding a context for occurrence of the event; partitioning the vectors associated with the software of the set to generate a data group representative of a behavior, a behavioral label being associated with the data group; associating a behavioral label with a vector, which is representative of the data group to which the vector belongs, and associating a trace of behavioral labels with a trace of vectors, the trace of labels being representative of execution of a software agent, and extracting in the trace of labels at least one behavioral signature associated with the software.

Method for constructing behavioural software signatures

A method for managing a cloud computing system, capable of allocating computing and network resources to a plurality of clients, each client being associated with at least one user likely to access the computing and network resources allocated to the client by the cloud computing system. This method includes, for at least one client of the cloud computing system: providing to the client a meta-model having a plurality of elements defining an access control model and an access control policy for the client; receiving an instance of the meta-model provided by the client, this instance defining, for the client, an access control model and an access control policy based on this access control model; and applying the access control policy to control an access of a user of the client to at least one resource allocated to the client by the cloud computing system.
