A Review on User Behavior Profiling and Decoy Technology in Cloud Computing

Abstract

Now a day's information technology growing vastly to provide users with lots of services but it will lead to security problems. One of them is secret key file. Password files have a great deal of security issue that has influenced a great many clients as well the same number of organizations. Cloud computing is an emerging computing paradigm in which resources of the computing infrastructure are provided as services over the Internet. Cloud computing significantly modifies the way we use computers and guarantees access and storage of our personal data and business information. These new computing and communication models face new data security challenges. To keep sensitive userdata confidential against untrusted servers, existing solutions usually apply cryptographic methods like encryption by disclosing data decryption keys only to authorized users. But like encryption fail to prevent data from the attacks of theft, especially in the cloud service provider in case key is lost by user or owner. We propose a different approach to overcome these problems in the cloud using decoy technology and user behavior profiling. The users using the Cloud are trapped and their access patterns are recorded. Every User has a unique profile which is monitored and updated. We monitor data access in the cloud by the users and detect abnormal data entry patterns. When unauthorized user try to access or is detected and challenged by challenge questions, we begin the wrong attack by returning the bulk of the information to the attacker. This protects users' real data from being misused.
