摘要:
The invention broadly contemplates a computing system that offers high-speed recovery. The system is configured to offer such a high-speed solution via an instant roll back scheme. The system utilizes a virtualization to handle the system state and provide a rescue and recovery like solution without requiring a full system reboot. The system is configured to utilize virtualization, e.g. through the use of a hypervisor to track the fundamental system components. This enables the system to very quickly back the system up on a rolling basis via tracking atomic changes and offering the instant rollback at essentially any point following an atomic change, should common system difficulties be encountered.

A method, apparatus, and system are disclosed for configuring an operating system on a target computer. A configuration module configures a target computer as a diskless client. A boot module boots the target computer to a setup state. A communication module establishes communications between the target computer, a donor storage device of a donor computer, and a virtual disk. A copy module copies a configuration image from the donor storage device to the virtual disk. The configuration image comprises an operating system and a software configuration installed on the donor computer. A modification module modifies the configuration image on the virtual disk to conform to a hardware configuration of the target computer.

If a user forgets the power-on password of his computer, he can depress the “enter” key or “access” key once to cause the BIOS to locate the power-on password in memory and attempt to unlock the HDD using the power-on password to boot a secure O.S. The HDD password either can be the same as the power-on password or the HDD can recognize the power-on password for the limited purpose of allowing access to the secure O.S. In any case, the secure O.S. is booted for password reset.

An arrangement for facilitating remote booting in diskless client systems as just described. To this end, there is broadly contemplated herein the employment of a hypervisor that can freely accommodate a variety of booting arrangements for a given OS. This then ensures that few if any modifications, especially costly ones, would need to be made to the OS to ensure greater versatility.

An apparatus, system, and method are disclosed for protecting hard disk data in multiple operating system environments. The present invention restricts access of a hard file to a range of logical addresses using a controller module configured to access a hard file in response to a request for a logical address, a set zero module configured to add an offset value to each request for a logical address on a hard file, and a set max module configured to set a maximum logical address accessible on a hard file. The invention limits access to a lower protected area with logical addresses below the range of logical address and a host protected area with logical address above the range of logical addresses.
摘要:
A method and system for remotely isolating faults in computer network devices coupled to a computer network. A plurality of first computer units are coupled to the computer network. The plurality of first computer units are located on a user side of the computer network. A plurality of second computer units are coupled to the computer network. The plurality of second computer units are located on a service provider side of the network. One of the plurality of second computer units is designated to provide computing services to one of the plurality of first computer units. One of the plurality of first computer units experiencing a fault communicating with its designated second computer unit uses another of the plurality of first computer units as a proxy computer unit to remotely isolate the fault.

Systems, methods and products are described that provide homepage re-assignment. One aspect includes displaying a default homepage desktop view from among a plurality of scrollable desktop views; receiving user input via a user input device; opening a homepage re-assignment utility responsive to receiving said user input, said homepage re-assignment utility including a display indicating one or more desktop views selectable as a new homepage; and responsive to receiving a user input indicating a selection of a desktop view as a new homepage, changing a default homepage setting to a desktop view selected as a new homepage. Other embodiments are described.
摘要:
An apparatus, system, and method are disclosed for securely authorizing changes to a transaction restriction. A security module securely stores encryption keys for a payment instrument. The payment instrument electronically transacts payments and includes a transaction restriction. An authentication module receives an authentication from a user of the payment instrument. The security module validates the authentication with a first encryption key. In addition, the security module authorizes a change to the transaction restriction using a second encryption key if the authentication is valid. The security module resides on a computer that the user designates as authorized to validate the authentication.
摘要:
An exemplary apparatus includes one or more processors, volatile memory, a storage drive and circuitry configured to establish a network connection and to attempt to send credentials via an established network connection. Such an apparatus further includes circuitry configured, responsive to authentication failure after an attempt to send credentials, to release an implemented security policy and load an operating system stored on the storage drive, and, responsive to an attempt to send credentials, to maintain an implemented security policy and to use an operating system exposed via an established network connection and associated with the sent credentials Such an apparatus optionally includes circuitry configured to implement a security policy that isolates at least a portion of a local storage drive. Various other apparatuses, systems, methods, etc., are also disclosed.
