With the development of mobile

cloud and Io T

the security of services is characterized by unclear boundary

uncontrolled environment

data attack and so on. The traditional ways of defense face serious problem while lots of new attacks appearing. Individual technology isn’t able to protect service security. Service systems face a lot of serious problem such as plug-in cheating

identity counterfeiting

trojan virus

system intrusion and so on. So service security must be protected covering terminals

pipe

and cloud. service security system covering "terminal

pipe

and cloud" is designed and put forward in this paper. Based on the framework including security component deployed in the terminal side and the security gateway deployed in the cloud side

the security mechanisms such as application security

channel security

data security

host and system security and so on are provided to the consumers’ service systems

in order to protect the full cycle security of mobile internet services

Io T services and other areas of service and so on.
