Cloud computing utilizes various technologies which provide on-demand services over the Internet that arises several security issues. Moreover, due to the multitenant nature of the Cloud, data is stored in multiple locations, which often leads to various security issues and threats. Cloud security investigates various security attributes, including vulnerabilities, threats, risks, and attack models. Also, confidentiality, authenticity, integrity, availability of the cloud resources as well as service of different layers are breached, which raised new security concerns. Several research books presented cloud security concepts, threats, and attacks. This list targets to provide leading research books in the area of cloud security with open research issues and the ways of tackling these threats.
