An electronic device may include a memory and at least one processor operatively connected with the memory. The at least one processor, including processing circuitry, may run a user application in a first area operating with a first permission and run an operating system in a second area operating with a second permission higher than the first permission. The memory stores instructions configured to, when executed, cause the at least one processor to detect an operation of at least one first device included in the electronic device, in a third area operating with a third permission higher than the second permission, deliver a detection signal for the at least one first device to a fourth area, an execution environment of which is separated from the first area, the second area, and the third area, in the third area, and provide a notification that the at least one first device is operating using at least one specified second device, in the fourth area. The fourth area may be an area on a second virtual machine, an execution environment of which is separated from the first area and the second area being areas on a first virtual machine by a hypervisor executed in the third area.

Electronic device and operating method for providing an operating notification for device included in the electronic device

An electronic device for controlling access to a device resource, and an operation method thereof, are disclosed. The electronic device may include a memory; and a processor configured to execute at least one operating system executed in a first region allowing an operation based on a first authority; execute at least one application executed in a second region allowing an operation based on a second authority; and in response to detection of access to at least one device resource by the at least one application, determine authority of access to the at least one device resource by using an authority determination module executed in a third region allowing an operation based on a third authority.

Electronic device for controlling access to device resource and operation method thereof

An electronic device for executing various operating systems is provided. The electronic device includes first and second hardware devices, a first operating system (OS), a second OS different from the first OS, and a processor configured to control the first hardware device to process first data from a first program executed on the first OS, obtain a command for executing the second OS, generate a container for executing the second OS based on a kernel of the first OS in response to the command for executing the second OS, execute the second OS on the generated container, execute a second program on the second OS, obtain second data regarding the second program from the second OS via socket communication by a control application installed on the first OS, and control the second hardware device to process the second data regarding the second program based on the first OS using the installed control application.

Electronic device for executing multiple operating systems and method of controlling same

A method for providing an anti-rollback secure timer service includes determining, at a device which includes a processor providing a trusted execution environment (TEE), a trusted memory, and a real time clock (RTC) accessible through an operating system of the device, an initial reference time value, by a secure timer application running in the TEE, the initial reference time value determined based on an initial value of the RTC obtained during booting of the device and a time delta value. The method further includes determining an updated reference time value based on the initial reference time value, a second value of the RTC, and a previously stored old reference time value, determining an updated time delta value based on the second value of the RTC and the updated reference time value, and storing the updated time delta value and the updated reference time value in the trusted memory.

System and method for anti-rollback

A method for operating an electronic device, the method including spawning a name space tool (NST) as part of a boot process of a host OS, wherein the NST is a process with a plurality of root privileges of the host OS. The method further includes spawning, by the NST, a container for a guest OS, wherein the container for the guest OS is mapped to a dedicated domain in the host OS, and dropping, by the NST, a root privilege of the host OS in response to spawning the container for the guest OS.
