Security is top concern for the people of IT from the past. With the advent of new technologies the severity of the problem has been changing its shape. A number of threats and their counter measures had been identified. Similar is the Cloud based environments. In spite of large number of features provided by Clouds, they are not able to attain attention of large number of business community. Cloud Security Alliance (CSA) is the top most working group working on the security issues of the Clouds. In this paper we have studied the various security attacks (in general) with reference to the Clouds (as per The Treacherous 12 -Cloud Computing Top Threats in 2016, CSA report defeating insider threat survey(2016) ,Cyber Security Trends Report (2017)) and Malicious Insider attacks (in particular).

Security is a critical factor for any of the computing platforms. Cloud computing is a new computing environment but still, its basic technology is the Internet. Thus, Cloud computing environment not only has the threats of its own but it is also prone to security issues of its underlying technology i.e. Internet. In this paper, the authors are proposing a secure routing framework viz. Authenticated Dynamic Routing in Cloud Networks (ADRCN) to mitigate the malicious insider attacks while maintaining the path integrity in the Clouds. Symmetric cryptography with hashing is used to maintain the integrity of the path between the source and destination. The purpose of ADRCN is to maintain the integrity of the path between the client and data center. If malicious insider tries to perform an attack between the client and the data center then it will be detected. This work aims to give a solution for detection and prevention of malicious insider attacks in Cloud-based environments.

Cloud security is one of the major issues which are affecting the acceptance of Cloud computing (CC). In spite of the number of benefits offered by CC, it also suffers from a myriad of security vulnerabilities. Security is the prime concern while we are accessing the resources from the Cloud through the Internet. This research work is primarily on IAAS (Infrastructure as a service). Here a protocol called Authenticated Routing on Cloud Network (ARCN) has been proposed, to secure the communication route between the client and service provider. The proposed protocol ARCN uses the public key cryptography to mitigate the various security attacks like malicious insider attacks, Spoofing, Falsified routes, DoS, etc.
