Abstract
A method and a detection entity for detecting attacks in a system including at least two host servers. Each host server hosts a set of virtual machines. The detection entity performs acts of: detecting that a number of migrations of virtual machines from one server to another during a current time period is greater than a threshold value; partitioning the virtual machines of the system into a first subset having a stable profile of consumption of at least one resource, and into a second subset having a fluctuating profile; calculating, for the pairs of virtual machines of the second subset, a value of temporal correlation between the two profiles of the pair; and identifying in the second subset the virtual machines for which the correlation value is greater than or equal to a threshold correlation value, the machines being identified as constituting the origin of the attack.
