Abstract: A method to test an OS kernel interface, such as an eBPF helper function. The interface has a grammar that defines the kernel interface. Testing is carried out using eBPF code that invokes and tests the interface using a fuzzing engine. To facilitate the process, additional user space code is configured to generate at least one kernel event that triggers the eBPF code to run, and to transform inputs from the fuzzing engine according to the grammar that defines the kernel interface. After loading the eBPF code into the OS kernel, the user space code issues the kernel event that causes the eBPF code to run. In response, and as the fuzzing engine executes, the eBPF code records arguments sent to the OS kernel through the kernel interface. The arguments are passed through a data structure shared by the eBPF code and the user space code. By recording the arguments and other diagnostic information, the security of the kernel interface is evaluated.

Abstract: A method, apparatus and computer program product for scheduling placement of containers in association with a set of hosts. The technique utilizes metrics that characterize container-specific risks. A first metric is a host interface risk for a container that quantifies how similar or dissimilar the container is relative to other containers running on a host. Preferably, host interface risk is derived with respect to a system call interface comprising a set of system calls, and the metric is based at least in part on a measure of dissimilarity among system calls. A second metric is a data sensitivity score that quantifies a degree to which sensitive data accesses are associated to the container. Based at least in part on the host interface risk scores and the data sensitivity scores, one or more containers are automatically scheduled for placement on the set of hosts to minimize security risk for the set of hosts.

Abstract: Described are techniques for application hardening. The techniques include generating application traces using fuzzing for an application with a known security vulnerability, where the application traces include good traces that do not result in exploitation of the known security vulnerability and bad traces that result in exploitation of the known security vulnerability. The techniques further include identifying code segments that are executed by the bad traces and not executed by the good traces. The techniques further include modifying the identified code segments using binary rewriting.

Abstract: A method, computer system, and a computer program product for data processing, comprising obtaining a plurality of files from a data source. These files are analyzed the files for information about the content and in order to determine structural information of each file. Once the files have been analyzed, information in each file may be sorted and categorized by common content. Sensitive information may also be extracted and categorized separately. Information may then be then merged using the categories to create a single unified file.

In aspects, a sensor is disposed on a distal face of the retractable shield. In aspects, a surgical system including the surgical cutting device includes control circuitry configured to receive sensed data from the sensor and to provide an output based thereon.

Abstract: Navigation systems, methods and software for assisting in determining whether a tool is properly installed on a surgical device. A protective packaging retains the tool and has a trackable feature. The trackable feature has a predetermined state defined relative to the tool and the trackable feature is detectable by a localizer. One or more controllers acquire the actual state of the tool based on the detected trackable feature and compare the actual state of the tool with an expected state of the tool, which is based on an expected condition in which the tool is properly mounted to the surgical device. Based on the comparison, the one or more controllers can determine whether the tool is properly mounted to the surgical device.

Abstract: An approach is provided that, after receiving a request to execute a computer program, determines an active set of metadata that corresponds to the requested computer program and then loads basic blocks of the requested computer program into memory. One of the loaded basic blocks is a starting block of the requested computer program. The memory also stores basic blocks corresponding to some previously loaded computer programs. The approach also inactivates basic blocks that are currently stored in the memory, with the inactivated basic blocks being identified based on a comparison of the active set of metadata to the sets of metadata that corresponding to the basic blocks of previously loaded computer programs. After inactivating some basic blocks, the approach executes the starting block of the requested computer program.

Abstract: Protective packaging, surgical kits, systems, and methods are described herein for assisting in determining whether a tool is properly installed on a surgical device. The protective packaging retains the tool and has trackable features defined relative to a tool center point of the tool. The trackable features have a predetermined state defined relative to the tool center point and the trackable features are configured to be detectable by a localizer to locate the tool center point. One or more controllers can compare the actual state of the tool center point with an expected state of the tool center point, which is based on an expected condition in which the tool is properly mounted to the surgical device. Based on the comparison, the one or more controllers can determine whether the tool is properly mounted to the surgical device.

Abstract: Multiple execution traces of an application are accessed. The multiple execution traces have been collected at a basic block level. Basic blocks in the multiple execution traces are scored. Scores for the basic blocks represent benefits of performing binary slimming at the corresponding basic blocks. Runtime binary slimming is performed of the application based on the scores of the basic blocks.

Abstract: A drill assembly including a cutting tool slidably movable along a longitudinal axis of the drill assembly and drivable to cut an object. In an active configuration, a pressure loaded drive control assembly transfers energy from a motor to the cutting tool to drive the cutting tool. In an inactive configuration, the pressure loaded drive control assembly prevents energy transfer from the motor to the cutting tool. A biasing member of the pressure loaded drive control assembly is configured to bias the pressure loaded drive control assembly in the inactive configuration. Depressing the cutting tool against the object moves the cutting tool along the longitudinal axis and moves the pressure loaded drive control assembly to the active configuration. The biasing member returns the pressure loaded drive control assembly to the inactive configuration when the cutting tool is no longer depressed against the object.
