摘要:
A method and system is described for a wireless client computer to be connected via an access point to a network only if the wireless client computer has executed all requisite anti-virus programs. Where necessary, a signal from the access point notifies an anti-viral program server that an anti-virus needs to be immediately downloaded to the wireless client computer. An anti-virus fix is installed on the wireless client computer, and a full session is then initiated between the wireless client computer and a wireless network via the access point.

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).

A “setmax” command is issued in BIOS to hide the service area (HPA) of a HDD during normal operation, so that the HPA cannot be accessed or erased inadvertently by the user or by a virus. Pressing a special key (e.g., F11) during booting permits access to the HPA.

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.

A computer determines whether it has been booted from a hard disk drive or from an alternate source (e.g., a floppy drive or portable memory) that entails a higher risk of importing a virus into the computer, and if it is determined that a non-HDD source was booted from, corrective action such as a virus scan can be preemptively taken.

A data processing system and method are disclosed for maintaining secure user private keys in a non-secure storage device. A master key pair is established for the system. The master key pair includes a master private key and a master public key. The master key pair is stored in a protected storage device. A unique user key pair is established for each user. The user key pair includes a user private key and a user public key. The user private key is encrypted utilizing the master public key. The encrypted user private key is stored in the non-secure storage device, wherein the encrypted user private key is secure while stored in the non-secure storage device.

A client computer is connected via a network to an anti-virus server and polls the server for indication 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 data processing system and method are disclosed for protecting data within a hard disk drive included within a data processing system. Data is generated. A signature value is provided which is stored in a signature device. The signature device is capable of being inserted into and removed from a computer system. A textual description of the data is created. The data is encrypted utilizing both the signature value stored on the device and the textual description. The encrypted data is then stored on the hard disk drive. The data processing system does not permanently store encryption keys.

An apparatus, system, and method are disclosed for granting hypervisor privileges. An installation module installs a monitor hypervisor wherein only the monitor hypervisor is granted the hypervisor privileges by the computer. An authentication module authenticates a second hypervisor. An eviction module evicts the monitor hypervisor if the second hypervisor is authenticated. The installation module further installs the second hypervisor after the monitor hypervisor is evicted so that only the second hypervisor is granted hypervisor privileges by the computer
摘要:
A method, system, and program product for enabling administrative recovery of a user's lost/forgotten boot-up passwords without compromising the administrative/master password(s). A restricted-use password is dynamically generated from a first hash of a random number generated on a client system and a secret retrieved from a secure device associated with the client system. The restricted-use password operates as a master password but is not the administrative password of the client system. Once the password is generated, it is provided to the user/client system to enable user access to said client system and hardfile and reset of the user passwords.
