    摘要: The security of web widgets is improved by transferring a set of access control decisions conventionally handled by the Web Runtime system (WRT) to a more secure portion of the computing system, such as a kernel in the operating system. Access control rules are extracted and provided to the more secure portion. This may be performed during widget installation or at invocation of a widget. During runtime, the more secure portion performs security checking functions for the widget instead of the WRT.

    摘要: In one embodiment, a method for establishing a secure multicast channel between a service provider and a terminal is provided. A request is received from the service provider for a configuration of the terminal. A configuration of the terminal at a first time is sent to the service provider. A security key is obtained, wherein the security is bound to the configuration of the terminal at the first time. Then the security key is decrypted using a configuration of the terminal at a second time, wherein the decryption fails if the configuration of the terminal at the second time is not identical to the configuration of the terminal at the first time. A secure multicast channel is then established with the service provider using the security key.

    摘要: Methods and devices for increasing or hardening the security of data stored in a storage device, such as a hard disk drive, are described. A storage device provides for increased or hardened security of data stored in hidden and non-hidden partitions of a storage medium in the device. An algorithm may be utilized for deriving a key that is used to encrypt or decrypt text before it is read from or written to the hard disk. The algorithm accepts as input a specific media location factor, such as an end address or start address of the block where the text is being read from or written to, and a secret key of the storage component. The output of the algorithm is a final key that may be used in the encryption and decryption process. Thus, in this manner, the final key is dependent on the location of the block where the data is being written or read, thereby making it more difficult to tamper with the data, which may be stored in a hidden or non-hidden partition of a hard disk.

    摘要: A method and system is provided for securing micro-architectural instruction caches (I-caches). Securing an I-cache involves maintaining a different substantially random instruction mapping policy into an I-cache for each of multiple processes, and for each process, performing a substantially random mapping scheme for mapping a process instruction into the I-cache based on the substantially random instruction mapping policy for said process. Securing the I-cache may further involve dynamically partitioning the I-cache into multiple logical partitions, and sharing access to the I-cache by an I-cache mapping policy that provides access to each I-cache partition by only one logical processor.

    摘要: Security can be enforced in a consistent manner with respect to various computing environments that may be operable in a computing system. Consistent security criteria can be generated, based on input security criterion, in a computer readable and storable form and stored in a computer readable storage medium, thereby allowing the consistent security criterion to be effectively provided to a computing system for enforcement of the input security criterion in a consistent manner with respect to, for example, (a) a first executable computer code effectively supported by an Operating System (OS), and (b) a second computer code effectively supported by the Virtual Computing Environment (VCE). A Trusted Component (TC) can effectively provide a consistent security criterion as a part and/or form that is suitable for a particular computing environment. The TC can, for example, be an automated tool that performs various functions including: verifying the consistency of security criteria, generation and deployment of consistent security criteria, and transformation of security criteria to parts and/or forms suitable for various computing environments. In addition, a Virtual Computing Environment (VCE) can obtain from the Operating System (OS) one or more security criteria. The Virtual Computing Environment (VCE) can be operable in a Trusted Computing Environment (TCE) and interface with a Trusted Operating System (TOS) that effectively enforces Mandatory Access Control (MAC), thereby allowing the Virtual Computing Environment (VCE) to leverage the security provided by the OS. The OS can, for example, be a Security-Enhanced Linux (SELinux) Operating System operating as a Trusted Component in a Trusted Environment that includes a Trusted Security Agent (TSA) operable to deploy consistent security criteria.

    摘要: Techniques for detecting unauthorized use (e.g., malicious attacks) of the computing systems (e.g., computing devices) are disclosed. Unauthorized use can be detected based on patterns of use (e.g., behavioral patterns of use typically associated with a human being) of the computing systems. Acceptable behavioral pattern data can be generated for a computing system by monitoring the use of a support system (e.g., an operating system, a virtual environment) operating on the computing system. For example, a plurality of system support provider components of a support system (e.g., system calls, device drivers) can be monitored in order to generate the acceptable behavioral pattern data in a form which effectively defines an acceptable pattern of use (usage pattern) for the monitored system support provider components, thereby allowing detection of unauthorized use of a computing system by detecting any deviation from the acceptable pattern of use of the monitored system support provider components.
