39 results about "Event stream processing" patented technology

Event stream processing, or ESP, is a set of technologies designed to assist the construction of event-driven information systems. ESP technologies include event visualization, event databases, event-driven middleware, and event processing languages, or complex event processing (CEP). In practice, the terms ESP and CEP are often used interchangeably. ESP deals with the task of processing streams of event data with the goal of identifying the meaningful pattern within those streams, employing techniques such as detection of relationships between multiple events, event correlation, event hierarchies, and other aspects such as causality, membership and timing.

Stream-Oriented Database Machine and Method

An event stream processing device capable of processing larger numbers of events while simultaneously responding to queries. This is achieved through sequential storage of data, the maintenance in memory of information pertaining to the most recent events for each entity monitored and the aggregation of file read / write requests in a single thread which is capable of optimising the execution of those requests.

Transactional quality of service in event stream processing middleware

Computer implemented method, system and computer usable program code for achieving transactional quality of service in a transactional object store system. A transaction is received from a client and is executed, wherein the transaction comprises reading a read-only derived object, or reading or writing another object, and ends with a decision to request committing the transaction or a decision to request aborting the transaction. Responsive to a decision to request committing the transaction, wherein the transaction comprises writing a publishing object, events are delivered to event stream processing queries, and are executed in parallel with executing of the transaction. Responsive to a decision to request committing a transaction that comprises reading a read-only derived object, a validation is performed to determine whether the transaction can proceed to be committed, whether the transaction should abort, or whether the validation should delay waiting for one or more event stream processing queries to complete.

Methods for behavioral detection and prevention of cyberattacks, and related apparatus and techniques

A security engine may use event-stream processing and behavioral techniques to detect ransomware. The engine may detect process behavior associated with encrypting a file, encrypting a storage device, or disabling a backup file, and may assign a ransomware category to the process based thereon. The engine may initiate protection actions to protect system resources from the process, which may continue to execute. The engine may monitor the process for specific behavior corresponding to its ransomware category. Based on the extent to which such specific behavior is detected, the engine may determine that the process is not ransomware, assign a ransomware subcategory to the process, or adjust the process's threat score. Monitoring of the process may continue, and the threat score may be updated based on the process's behavior. If the threat score exceeds a threshold corresponding to the ransomware category (or subcategory), a corresponding policy action may be initiated.
