5. Denial Of Service
Denial of Service attacks can overwhelm a cloud service by forcing it to consume tons of system resources and prevent legitimate users from being able to use the service. Distributed Denial of Service attacks tend to get a lot of media attention, but there are other types of DoS attacks that can affect cloud computing, the CSA said. For example, attackers can launch asymmetric application-level DoS attacks by exploiting vulnerabilities in Web servers, databases or other cloud resources to take down an application with an extremely small payload.
