    摘要: A method, apparatus, and system are disclosed of forward caching for a managed client. A storage module stores a software image on a storage device of a backend server. The backend server provides virtual disk storage on the storage device through a first intermediate network point for a plurality of diskless data processing devices. Each diskless data processing device communicates directly with the first intermediate network point. The storage module caches an image instance of the software image at the first intermediate network point. A tracking module detects an update to the software image on the storage device. The storage module copies the updated software image to the first intermediate network point as an updated image instance.

    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: A system, method, and program product is provided that establishes a shared secret between a computer system and a peripheral device such as a removable nonvolatile storage device or a printer. After establishing the shared secret, the peripheral device is locked. After the peripheral device is locked, an unlock request is received and the shared secret is sent to the peripheral device. The peripheral device then attempts to verify the shared secret. If the shared secret is successfully verified, then the peripheral device is unlocked allowing use of the device by using an encryption key that is made available by the verified shared secret. On the other hand, if the shared secret is not verified, then the peripheral device remains locked and use of the device is prevented.

    摘要: A system and method for using a client-side hypervisor in conjunction with a secure network-side monitoring mechanism to detect removable media insertions since a client's last network session with the secure network is presented. The hypervisor uses a “client-side insertion value” to track the number of times that a user inserts removable media into a socket located on the client. When the client is connected to the secure network, the client's hypervisor notifies the secure network of each insertion and the secure network increments a “secure network-side tracker value.” For each login request, the client includes the client-side insertion value, which the secure network compares against its secure network-side tracker value. When the two values are different, the secure network sends an action request to the client, such as a request to perform a full system scan. Once the client performs the action, the client's hypervisor resets its client-side insertion value and attempts to logon to the secure network again.

    摘要: An apparatus, system, and method are disclosed for securing I/O communications between a blade and peripheral interface device. The apparatus includes a determination module, a source security module, and a source communication module. The determination module identifies I/O data configured for transmission to a destination module configured to receive secure I/O data. The source security module encrypts the I/O data to generate secured I/O data such that subsequent decryption of the secured I/O data is restricted to a destination module. The source communication module transmits the secured I/O data over a vulnerable communication link to the destination module. The vulnerable communication link comprises a message intercept vulnerability. The destination module is configured to unencrypt the secure I/O data for a destination device such as a display device.

    摘要: To unlock a HDD when a computer is in the suspend state, at both BIOS and the HDD a secret is combined with a password to render a new one-time password. BIOS sends its new one-time password to the HDD which unlocks itself only if a match is found. The new one-time password is then saved as an “old” password for subsequent combination with the secret when coming out of subsequent suspend states. In this way, if a computer is stolen the thief cannot sniff the bus between BIOS and the HDD to obtain a password that is of any use once the computer ever re-enters the suspend state.

    摘要: An apparatus, system, and method are disclosed for computer system power management. A control module 602 is activated on a computer 200 in response to an event and enters 818 a standby state if the computer 200 is not already 814 in the standby state. A policy module 604 detects 904 a power source of a predetermined type connected to the computer 200 and dictates 908 one or more processors 302 of higher power consumption for a more abundant type of power source such as an AC adapter 314, or one or more processors 304 of lower power consumption for a less abundant type of power source such as a battery 318. A configuration module 606, activated by the control module 602, switches 1004 the computer 200 to one or more processors 302 and 304 of a predetermined power consumption as dictated and exits 1016 the standby state.
