Abstract: Aspects of the present disclosure relate to computer system security. A machine accesses a set of records corresponding to a set of users having access to a computer system. The machine stores, for each user in the set of users, a baseline profile representing baseline activity of the user with respect to a set of data sources of the computer system. The machine monitors activity of the set of users with respect to the set of data sources. The machine determines, based on monitoring the activity of the set of users, that a user action of a specified user, with respect to one or more data sources from the set of data sources, is anomalous relative to the baseline profile of the specified user. The machine provides a digital transmission representing the anomalous user action.

Abstract: Techniques for determining a preferred HTTP protocol for communication between a client device and a server over a network are described. A first type of HTTP probe is transmitted over a network from a client device to a server. A second type of HTTP probe is transmitted over a network from the client device to the server. If either the first type of HTTP probe response or the second type of HTTP probe response, the type of the HTTP probe response received is the preferred communication protocol. If the first type of HTTP probe response and the second type of HTTP probe response is received, a type of HTTP probe response received first is the preferred communication protocol. The client device communicates with the server over the network using the preferred communication protocol.

Abstract: Embodiments identify a station that rotates an over the air station address. As address rotation was not originally designed into wireless networks, the rotation can introduce communication challenges for the station. The embodiments derive that traffic referencing two different over the air station addresses are associated with a single common station. This is accomplished by determining a similarity between properties of two sets of traffic. A first set of traffic references the first over the air station address and a second set of traffic references the second over the air station address. If the properties common across the two sets of traffic indicate sufficient similarity, the embodiments determine that both sets of traffic are associated with a single device. Network configuration of the device is then adjusted based on the determination.

Abstract: A method is performed by a gateway node that is at a boundary of the first network domain and the second network domain. The method includes receiving an end-to-end delay measurement request sent by the first node to measure end-to-end delay between the first node and the second node. The end-to-end delay measurement request is configured to initiate a first delay measurement process configured for use in the first network domain. The gateway node sends to the second node a delay measurement request configured to initiate a second delay measurement process configured for use in the second network domain. The gateway node determines a delay measurement in the second network domain between the gateway node and the second node using the second delay measurement process. The gateway node sends to the first node an end-to-end delay measurement response that enables the first node to compute the end-to-end delay.

Abstract: Techniques for enabling service insertion using dynamic service path selection are described herein. In some aspects, the techniques described herein relate to avoiding a service route that passes through a service router when the second-leg path from the service router to a destination router is unreachable.

Abstract: Distance-based framing includes obtaining at least a video stream during an online conference session. The video stream, an audio stream received with the video stream, or both the video stream and the audio stream are analyzed and a framing that either focuses on a speaker in the video stream or provides an overview of participants in the video stream, the framing being is composed based on the analyzing. A potential error in the framing is detected based on further analysis of the video stream, the audio stream, and an amount of motion in the room. If the distance sensor data contradicts the potential error, the framing is maintained, but if the distance sensor data confirms the potential error, a new framing is generated.

Abstract: A system can receive user data from a computing device of a user. Based on the user data, the system can determine that the user will utilize a transport service to arrive at a destination location at a specified time. Prior to the specified time, the system can monitor transport service conditions within a region that includes a current location of the user, and determine a service request time for the user based at least in part on the transport service conditions. The system then automatically generates the service request for the user at the service request time to match the user to a transport provider.
