Cloud security risks DDOS attacks and defense mechanisms

Abstract

Protecting data privacy becomes an important issue with the greater rate of using cloud storage. The most effective solution is to encrypt data prior to uploading to the cloud. Due to benefits such as scalability and reliability, cloud-hosted services are increasingly being used in online businesses such as retail, health care, manufacturing, entertainment. Attackers are attempting to steal confidential information, interrupt services, and damage the cloud computing network of enterprises. How to search data encrypted with different keys efficiently, however, is still an open problem. This paper gives an overview of various security and privacy concerns related to the cloud computing environment and also provides the related solutions for each issue especially for DDOs attacks.
