Abstract: A computer network includes user endpoint devices geographically distributed relative to one another such that at least one of the endpoint devices is subject to a different set of data protection or privacy restrictions than other endpoint devices and data processing facilities coupled to the user endpoint devices over a network. The data processing facilities are in different geographical regions or sovereignties. A computer-based endpoint agent is in each of the endpoint devices. Each endpoint agent is configured to collect telemetry data relating to user activity at its associated endpoint device and transmit the collected telemetry data to a selected one of the data processing facilities, according to an applicable realm definition, in compliance with the data protection or privacy restrictions that apply to the agent's endpoint device.

Abstract: A computer-based method includes monitoring user activities at an endpoint device on a computer network, determining if one of the user activities at the endpoint device presents a potential threat to network security, creating an alert of the potential threat, and providing, with the alert, a redacted version of a screenshot from the endpoint device. One or more open windows that appeared on the screen of the endpoint device are obscured or removed in the redacted version of the screenshot of the endpoint device.

Abstract: A system controls access to data for customer of a multi-tenant software as a service (SaaS) system. A multi-tenant SaaS system cloud includes a metadata store. A customer-controlled storage realm includes a customer-controlled key management system (KMS) and a data store for storing encrypted customer data objects. An agent at a user endpoint identifies customer data for storage in the customer data store, transmits metadata and telemetry information related to the customer data to a SaaS application interface (API), and provides a storage reference for a SaaS metadata store. The agent is pre-configured with credentials from the KMS for storing customer data objects in the data store. The customer-controlled storage realm is not in direct communication with the SaaS system cloud.

Abstract: A distributed system provides access by a principal to a resource associated with sensitive data. Micro-services in communication with an authorization engine each include a resource provider that receives a resource action request from the principal to access the resource, determines a context for the request, and transmits the context to the authorization engine in an authorization request. The authorization engine receives the authorization request, resolves the authorization request context against a plurality of pre-defined resource conditions, and responds to the resource provider with an authorization response of allow, deny, or allow-with-conditions. The context for the request includes metadata regarding attributes of the principal, and each of the resource conditions includes a logical expression operating upon the attributes.

Abstract: Ellipticity in an illumination beam may be corrected by measuring an ellipticity of the illumination beam and substantially eliminating the ellipticity using a light attenuating filter at a defocus position of the illumination beam, wherein the light attenuating filter has a two-dimensional pattern that compensates for ellipticity variations in the illumination beam. The light attenuating filter may stand alone, or the filter may be combined with a uniformity correction system, such that it corrects both uniformity and ellipticity. In one embodiment, the light attenuating filter is printed with an assembly of microscopic dots according to the two-dimensional pattern.

Abstract: A system and method for uniformity correction is provided. The system includes a plurality of winged correction elements inserted into the illumination field in a defined configuration. Adjacent winged correction elements are overlapped to minimize induced uniformity ripple. Each winged correction element has a first protrusion on a longitudinal edge of the correction element and a second protrusion on the opposite longitudinal edge. The slope of a sloped edge of the first protrusion and the slope of a sloped edge of the second protrusion are tied to the slope of a gradient in the non-uniformity profile of the illumination field. In addition, the angles defined by the flat tip of the correction element and the sloped edge of the first and second protrusions are tied to the angle of a gradient of the illumination field.
