    摘要: A method and system is described for selectively downloading antidotes onto a client computer. The client computer is connected via a network interface card (NIC) to a network that contains an anti-virus server. The NIC is initially logically isolated from the client computer, thus permitting the NIC to autonomously examine packets to and from the client computer and the network. The NIC selectively accepts packets only from trusted Internet Protocol (IP) addresses that conform to a security format such as Internet Protocol Security (IPSec).

    摘要: A client computer is connected via a network to an anti-virus server. A signal from the anti-virus server notifies the client computer that an anti-virus needs to be immediately downloaded from the anti-virus server. The client computer disengages from the network, and re-establishes a link with only the trusted anti-virus server. The anti-virus fix is installed, the client computer re-booted, and the client computer is then allowed to reconnect to the full network. If the client's primary operating system (OS) is infected, a secondary OS in the client computer performs the anti-virus download and execution. The disengagement from the network is performed by applying a filter in a network interface card (NIC) driver by the primary OS, the secondary OS, a service processor (SP), or by a virtual machine manager (VMM), depending on which is available at the client computer.

    摘要: A system, method, and program product is provided that initializes a counter maintained in a nonvolatile memory of a security module to an initialization value. The security module receives requests for a secret from requesters. The security module releases the secret to the requesters and the released secrets are stored in memory areas allocated to the requesters. A counter is incremented when the secret is released. Requestors send notifications to the security module indicating that the requestor has removed the secret from the requestor's memory area. The security module decrements the counter each time a notification is received. When the computer system is rebooted, if the counter is not at the initialization value, the system memory is scrubbed erasing any secrets that remain in memory.

    摘要: Systems, methods, and media for providing remote wake-up and management of systems in a network are disclosed. More particularly, hardware and/or software for a server to receive feedback from a client as to the status of its wake-on-LAN functionality is disclosed. Embodiments include hardware and/or software for determining a client to be managed, determining whether the client is active on the network, transmitting a first network packet comprising a wake-on-LAN packet, and receiving a return wake-on-LAN packet, which comprises an indication of the address of the client and an indication of the status of the wake-on-LAN functionality of the client. Embodiments may also include transmitting a command to start a management session on the client.

    摘要: An apparatus for securely backing up data using a cryptographic module includes a mass storage device having a first accessible portion and a second encrypted portion. The mass storage device is initialized to only decrypt the encrypted portion on the system that first created the encrypted portion. The cryptographic module may be a Trusted Platform Module (TPM) based on specifications from the Trusted Computer Group. The mass storage device comprises a trusted platform interface module configured to communicate with the TPM. The system may include a motherboard having a TPM, and the mass storage device. The method in one embodiment comprises providing a computer readable mass storage device, initializing a password module, transmitting an encrypted password to the cryptographic module, authenticating the encrypted password, decrypting the encrypted password, transmitting the decrypted password to the computer readable medium, and decrypting the second encrypted portion using the decrypted password.

    摘要: A system, method, and program product is provided that initializes expected PCRs stored in a TPM by generating and storing a random number, seeding expected PCRs with the random number, inputting a set of startup code processes to a hash algorithm resulting in a set of hash values, updating the expected PCRs using the set of hash values, and saving the expected PCRs in a nonvolatile data area that is secured by the TPM. Upon reboot, the random number is retrieved from the nonvolatile data area, the PCRs are seeded with the retrieved random number, the startup code processes are input to the hash algorithm process resulting in another set of hash values, the PCRs are updated using the resulting set of hash values, and an encrypted data object is decrypted in response to the PCRs being the same as the expected PCRs.
