Cloud computing represents the trend of information technology.The de velopment of cloud computing is facing several challenges.Security issues are at the top of the list.This talk deeply analyzes the security problems of cloud computing.Cloud security problems are fundamental rooted in the cloud char acteristics—service outsourcing,sharing of computing infrastructure,dynamic complexity,superlarge system scale,multi-tendency,highly centralized re sources and the open federated structure.The talk lists several key security challenges to cloud computing,such as trust relationships,access control,user behavior monitoring and privacy protection.
