Abstract: Technical solutions are described for extending shrouding capability of a virtual server hosting system. An example method includes receiving a request to deploy a shrouded virtual server using a predetermined set of hardware components, and using a shrouded mode. The method also includes adding a guest server to the hosting system, the guest server including the predetermined set of hardware components. The method also includes deploying a preconfigured hypervisor on the guest server, where the preconfigured hypervisor is deployed in an immutable mode that disables changes to security settings of the preconfigured hypervisor. The method also includes deploying, by the preconfigured hypervisor, a preconfigured boot image as an instance of the virtual server on the preconfigured hypervisor. The method also includes sending an identifier of the virtual server for receipt by the client device.

Abstract: A source code search comprises a two-pass search. The first pass comprises a topological measure of similarity. The second pass comprises a semantic measure of similarity. The query source code is a user-selected portion of source code. The results may be ranked and output to an I/O device.

Abstract: Mechanisms for booting a service processor are provided. With these mechanisms, the service processor executes a secure boot operation of secure boot firmware to boot an operating system kernel of the service processor. The secure boot firmware records first measurements of code executed by the secure boot firmware when performing the boot operation, in one or more registers of a tamper-resistant secure trusted dedicated microprocessor of the service processor. The operating system kernel executing in the service processor enables an integrity management subsystem of the operating system kernel which records second measurements of software executed by the operating system kernel, in the one or more registers of the tamper-resistant secure trusted dedicated microprocessor.

Abstract: Detection of a key logger includes determining a count of keystrokes that occur during each of a plurality of time windows. Write activity that occurs during each of the plurality of time windows can be measured. The number of key strokes occurring in window is compared with the write activity occurring during the window. In response to determining that the count of keystrokes in a time window is linearly related to the measurement of write activity in the time window for a threshold number of time windows of the plurality of windows, a notification of a potential presence of a key logger is provided.

Abstract: A static analysis tool configured to determine a significance of static analysis results. The static analysis tool can perform operations that include performing a static analysis of a computer program and generating the static analysis results in response to the performing the static analysis of the computer program. The operations can further include analyzing a description of a result item from the static analysis results, and based on the analyzing the description of the result item, assigning to the result item information from an ontology scheme. The operations can further include determining a significance value for the result item in response to the assigning the information from the ontology scheme and automatically performing an action associated with the result item based on one or more of the information assigned from the ontology scheme or the significance value.

Abstract: A stream of data contributions during a period is collected from a social media data source, the period spanning a broadcast of a content. The stream is analyzed to identify a change in a level of the data contributions during a sub-period of the period. A first time is selected to mark a beginning of the sub-period. A second time is selected to mark an ending of the sub-period. A data fragment is extracted from the data contributions occurring during the sub-period in the stream, the data fragment being descriptive of the content during the sub-period. In a recording of the content, a portion of the recording between the starting time and the ending time is selected as a segment of interest. The recording is annotated with the starting time, the ending time, and the data fragment to identify the segment of interest.

Abstract: Source code for a function of a computer program is compiled by compilers to generate executable code variants for the function according to different optimization approaches. Each executable code variant is executable on a same processor architecture. A binary file for the computer program is constructed that includes each executable code variant. At runtime of the binary file, one of the executable code variants is selected for the function. The selected executable code variant is used during execution of the computer program, until execution is halted.
