Depending on the
computational power in control of the attacker, a sideeffect
of the direct flooding attack on a Cloud service
potentially consists in that other services provided
on the same hardware servers may suffer from the
workload caused by the flooding. Thus, if a service
instance happens to run on the same server with
another, flooded service instance, this may affect its
own availability as well. Once the server’s hardware
resources are completely exhausted by processing the flooding attack requests, obviously also the other service
instances on the same hardware machine are no longer able to perform their intended tasks. Thus, the
Denial of Service of the targeted service instances are
likely to cause a Denial of Service on all other services
deployed to the same server hardware as well.
