Abstract:
Executing a single instruction/multiple data (SIMD) instruction of a program to process a vector of data wherein each element of the packet vector corresponds to a different received packet.
Abstract:
Method and Apparatuses for determining integrity of a platform and notifying a remote system. In one embodiment a verification agent accesses a portion of a memory on the platform at initialization of the platform to determine if the data has been compromised or corrupted. The verification agent causes the information to be transmitted to a remote system. The verification agent may be local to the platform for which integrity is determined, and transmit the information to a remote administrator. Alternatively, the agent may access the platform over a bus or private channel, or a network connection and indicate information regarding the verification process to an entity remote to the tested platform.
Abstract:
In general, in one aspect, a method is described that includes monitoring data received from input devices. The received data from the input devices associated with an application is copied when the application is active. The data is converted to user commands. Commands used to update the application are received from the application. The converted user commands are compared to the commands from the application. Mismatching commands are reported to a remote server.
Abstract:
In general, in one aspect, an add-in card includes inaccessible memory to store an identity key, wherein the identity key is to enable a secure communication link. The add-in card also includes an isolated execution environment and a machine-accessible medium comprising content. The content when executed by the isolated execution environment causes the isolated execution environment to route secure communications between an on-line application and a remote service provider through the isolated execution environment to provide a secure communication link therebetween, detect on-line application code modifications, detect on-line application process flow modifications, and notify, via the secure communication link, the remote service provider when a modification is detected.
Abstract:
A runtime integrity check may be implemented for a chain or execution path. When the chain or execution path calls other functions, the correctness of an entity called from the execution path is verified. As a result, attacks by malicious software that attempt to circumvent interrupt handlers can be combated.
Abstract:
Hardware of a virtualized processor based system detecting a specified type of memory access to an identified region of memory and in response to the detecting generating an interrupt for a virtual machine monitor (VMM) of the virtualized processor based system.
