Abstract: In order to distribute content made available by an entity of origin, a first distribution entity receives a request to access the content by a client entity. If this is a first access request received by the first distribution entity for the content, the distribution entity acts as a proxy: it receives, from the entity of origin or from a second distribution entity, and retransmits to the client entity, a response including the content, and it stores the content in a cache. In addition, it transmits, to the entity of origin or to the second distribution entity, a context request, receives in return a response including a description of the execution context of the access request, and stores the description. Otherwise, the first distribution entity uses the previously stored description in order to perform an execution of the later access request.

The method includes receiving second event data, the second event data including device metadata and a second ID that identifies the device. The method includes generating a second persona based on the second event data, the second persona including the second ID and a second event identifier that identifies a second user action. Additionally, the method includes determining that the first and second personas are associated with the device based on matches between the browser metadata and device metadata and transmitting a response to the device configured to route the device to the application state.

Abstract: A data security system collects collaboration platform collaboration settings through interfaces and analyzes those settings against a policy of common collaboration settings for security and compliance. The data security system interfaces with a plurality of heterogeneous online collaboration platforms, each having its own platform specific set of collaboration settings to control access to collaborative data. The data security system maps the set of common collaboration settings to the platform specific set of collaboration settings of each heterogeneous online collaboration platform from the plurality of heterogeneous online collaboration platforms and monitors a state of the platform specific set of collaboration settings of each heterogeneous online collaboration platform. Based on a determination that a platform specific collaboration setting does not comply with the collaboration setting policy, the data security system can take a remedial action or other action.

Abstract: Disclosed herein are methods, systems, and processes for centralized containerized deployment of network traffic sensors to network sensor hosts for deep packet inspection (DPI) that supports various other cybersecurity operations. A network sensor package containing a pre-configured network sensor container is received by a network sensor host from a network sensor deployment server. Installation of the network sensor package on the network sensor host causes execution of the network sensor container that further causes deployment of an on-premise network sensor along with a network sensor management system, a DPI system, and an intrusion detection/prevention (IDS/IPS) system. The configurable on-premise network sensor is deployed on multiple operating system distributions of the network sensor host and generates actionable network metadata using DPI techniques for optimized log search and management and improved intrusion detection and response (IDR) operations.

Abstract: Implementations are provided herein for encoding and transmitting streaming data from a client application to a server for storage without prior knowledge of the size of the streaming data. A header can be sent that includes a batch size chunk size. Raw streaming data can be packaged into the chunk. Chunks can be packaged and sent at any time prior to filling up with streaming data, by padding the chunk and including a footer that delineates the amount of raw stream data in the chunk. Chunks that are full can have a footer that delineates the entire chunk is raw stream data. It can be appreciated that you do not need to buffer data on the client side as chunks do not need to be full to send. Latency on processing streaming data can also be reduced by limited or eliminated buffering.

Abstract: The present disclosure provides a domain name resolution method and apparatus based on a plurality of availability zones (AZ). After receiving, from a client, a domain name resolution request including a domain name of a to-be-accessed resource, a domain name system (DNS) determines, from a plurality of AZs corresponding to the domain name, a first AZ in a service available state, where each of the plurality of AZs is capable of providing the to-be-accessed resource, and then sends an internet protocol (IP) address of the first AZ to the client. In this way, the DNS processes the domain name resolution request sent by the client. After receiving the domain name resolution request sent by the client, the DNS feeds back, to the client, an IP address that is of an AZ in the service available state and that corresponds to the domain name resolution request.
