THIN-CLIENT SYSTEM, ACCESS CONTROL METHOD, AND ACCESS CONTROL METHOD IN SAME

摘要

To heighten security in a thin client system, the thin client system includes: a communication unit 21 that receives a user ID and terminal information including at least current position information from a client terminal 10; a policy information extraction unit 22 that extracts policy information relating to a security policy stored in association with the terminal information received by the communication unit 21 on the basis of the terminal information; a virtual machine allocation unit 32 that allocates a virtual machine virtualizing an environment of the client terminal 10 to a server device 30 on the basis of the user ID received from the client terminal 10; and an access control unit 33 that restricts access to the virtual machine allocated by the virtual machine allocation unit 32 on the basis of the policy information extracted by the policy information extraction unit 22.
