A method of auditing at least one virtualized resource deployed in a cloud computing network, implemented by an administration device in respect of the at least one resource, able to administer virtual network functions, the virtual infrastructure or the network services. The method includes: storing a set of rules of the audit which are associated with the at least one virtualized resource; receiving from the at least one virtualized resource a message including an item of information about an event arising on the virtualized resource; correlating the item of information received with the set of stored rules; and if the correlation is positive, sending, to a recording device, a command message for writing at least one datum linked to the item of information received in a data register associated with the at least one virtualized resource.
