Cloud DoS attacks are multifaceted and prevent consumers of cloud services from accessing their cloud resources. A cloud DoS protection service has to be incorporated into the security architecture to shield the cloud provider from DoS attacks. A network DoS protection service updates the domain name service (DNS) to route all cloud provider traffic through the protection service, which filters attack traffic and routes only legitimate traffic to the cloud provider. Alternately, the cloud provider can route traffic to a DoS protection service when experiencing an attack, or create its own DoS protection service. Considering the insistence for unbreakable and impenetrable cloud security solutions, fresh cloud security patterns are being unearthed by security experts and researchers. In the future, there will be a few more security-related patterns.
