  • Patent number: 9323956
    Abstract: Methods and arrangements for managing a flash drive, hard disk, or connection between the two, in a manner to ensure that sensitive data is not decrypted at any time when it would be vulnerable. Accordingly, in a first implementation, the data may preferably be encrypted as it first goes into a flash drive and decrypted when it comes out of the flash drive. In another implementation, the flash drive may be logically bound to the hard disk, so that they would both use the same encryption key. In yet another implementation, if a hard disk is moved to another system, then the flash drive may also preferably be simultaneously moved.

  • Patent number: 8756667
    Abstract: In the context of computer systems, the generation of preboot passwords at a server instead of at a client. Preferably, preboot passwords generated at the server are distributed to the client, and a process is offered whereby a user can establish his/her own proxy, not known to the server, that can be used to release the stored passwords to the client hardware. Since the passwords are generated at the server, management of the passwords is greatly facilitated since they are generated at the site where they are stored. This also makes it easy to implement management features such as a group policy, since the password generation software will be able to make logical connections between users and hardware.

  • Patent number: 8726260
    Abstract: A technique for providing a software patch to an associated computer system includes receiving, at a wireless communication device, a communication. Next, it is determined, at the wireless communication device, whether the communication is associated with a software patch available for the associated computer system. When the communication is associated with the software patch, a notification is sent from the wireless communication device to the associated computer system that the software patch is available.

  • Patent number: 8702812
    Abstract: Methods and arrangements for ensuring that, when a computer system is stolen or otherwise misplaced, the system is rendered unusable (i.e., locked down). Conventional solutions have required software running on the system to perform the lockdown action, but in accordance with at least one preferred embodiment of the present invention is the linkage of TPM (Trusted Platform Module) and AMT (Active Management Technology) solutions whereby an AMT arrangement can remove secure data or identifiers so that any encrypted data present on the system will become unusable.

  • Patent number: 8566600
    Abstract: In accordance with at least one presently preferred embodiment of the present invention, there is broadly contemplated herein the managing of a POP not solely in the BIOS but at least partly in a more secure location. In accordance with a particularly preferred embodiment of the present invention, this location could be in a NVRAM (non-volatile random access memory) inside a TPM (trusted platform module). Most preferably, this location will contain code that the BIOS preferably will need to access and employ in order to complete the booting of the system.

  • Patent number: 8539246
    Abstract: Systems, methods and products are described that provide secure resume for encrypted drives. One aspect provides a method including: receiving an indication to resume from a suspended state at a computing device; responsive to authenticating a user at one or more input devices, accessing a value in a BIOS derived from authenticating the user at the one or more input devices; responsive to accessing the value, releasing a credential for unlocking one or more encrypted drives; and thereafter proceeding to resume from the suspend state.

  • Patent number: 8473747
    Abstract: Systems, methods and products are described that provide secure boot with a minimum number of re-boots. One aspect provides a method including receiving an indication to boot from a power off state at a computing device; responsive to authenticating a user at one or more input devices, releasing a value derived from authenticating the user at the one or more input devices; responsive to releasing the value, unlocking one or more encrypted drives with a previously established alternate credential; and thereafter proceeding to boot from the power off state. By not having to call the non-BIOS software each boot, this minimizes the number of reboots for each boot cycle.

  • Patent number: 8397231
    Abstract: Hypervisors are a new technology in the industry that enable multiple Operating Systems to co-exist on a single client. The use of a hypervisor provides a novel approach to determining the operability of an Operating System. Each Operating System is a virtualized Operating System, with its own IP address. According to a preferred embodiment, the capability Operating System has an application that is a monitor program that runs and provides information that is sent to the maintenance Operating System. The monitor program sends a status packet at regular intervals, which contains system power state and is a confirmation that the system is not hung. If the maintenance Operating System does not receive a packet at a regular interval, or in response to a query, then the maintenance Operating System will be aware that the capability Operating System is hung and will take appropriate measures.

  • Patent number: 8381304
    Abstract: A hard disk drive unit includes a microprocessor programmed to erase data stored within the drive unit if it is determined that a process potentially leading to a misuse of the data stored within the drive unit, and if secure disposal configuration data stored in nonvolatile storage within the drive indicates that the data is to be erased. Such a process includes initializing the drive unit for operation without providing a password matching a password stored in the drive unit, initializing the drive unit in a system not having CMOS configuration data matching the drive unit, and determining that a failure rate within the drive unit exceeds a threshold level.

  • Patent number: 8364943
    Abstract: Arrangements for employing a system BIOS (basic input/output system) to handle email during a suspended state (such as an “S3” state as will be better understood herebelow). Preferably, the BIOS is employed to “jump” between two suspended images such that, e.g., two more powerful OS's can be employed to manage the mail function.
