A method and apparatus provides for controlling the distribution and installation of operating systems. In one example, the method and apparatus partitions a storage device of a device into a first partition and a second partition. The method and apparatus installs a first operating system into the first partition of the storage device, obtains an image of the second operating system, the image including at least the second operating system pre-configured for operation with the device, and installs, using the first operating system, the image of the operating system to the second partition of the storage device. In an embodiment, the image is transmitted from one or more other devices. In an embodiment, two or more images are cached on the device according to the likelihood they will be used in the future.

In general, this disclosure describes techniques of managing resources in a service-oriented distributed computing system. As described in this disclosure, one or more control nodes provide for the efficient and automated allocation and management of resources within the distributed computing system. In order to provide automated allocation and management of computing functions and resources, a control node uses a set of governors. This set of governors includes a set of service governors to govern services used in the distributed computing system. The set of governors also includes a set of resource governors that govern individual resources of the services in the distributed computing system. The service governors and the resource governors may be implemented using finite state machines.

The invention discloses a data access control method of a block device of a VxWorks system driver layer. The method comprises the following steps: setting an authority library of a VxWorks system; performing basic package without disk cache on a block device interface to establish a CBIO (Cache Block Input / Output) device; performing embedded access to a monitor on a block device driver layer and a dosFs (Distributed Operating System Formal System Model) file system driver layer respectively; enabling that a task enters and accesses the monitor firstly during access of block device data, accessing the authority library which is previously set according to the matching of a current task ID (Identifier) and the block device, and controlling the access of the task to the block device data. Compared with the existing access control method, the method has the advantages that a better access control effect is realized and the security of data in the block device is improved.

The invention discloses a kbroker distributed operating system, a storage medium and an electronic device. The system is applied in a plurality of servers. The system comprises a plurality of app_service modules and a plurality of app_allocator modules. The app_service module is used for running service logic, and the app _ allocator module is used for managing running resources of an applicationprogram and distributing the app _ service module running the application program according to the demand of the running resources. The system comprises a plurality of kbroker_server modules and a plurality of kbroker_server modules. The management module is used for managing a corresponding server in the distributed operating system, and opening and closing an app_service module and an app_allocator module on the corresponding server, and the plurality of kbroker_server modules are in data communication connection. The system comprises a kbroker_superper module which is used for managing allprogram processes in the whole system. Under the support of the system, a developer only needs to pay attention to the service of the developer and develops a large server program like developing thesimplest single-thread program, a series of problems caused by increase of the page view are not needed to be paid attention to, the server clustering efficiency is improved, and the system provides adisaster recovery mechanism for software and hardware faults to achieve high availability.

A system and method for trigger-based scanning of cyber-physical assets, including a distributed operating system, parameter evaluation engine, at least one cyber-physical asset, at least one crypt-ledger, a network, and a scanner that detects trigger conditions and events and performs scans of cyber-physical assets based on the trigger and any relevant stored scan rules before storing scan results as time-series data.
