Abstract: Technology for risk-based access to secrets utilizes risk metadata tailored to secrets. Secrets include passwords, security tokens, digital certificates, and other items used for identity authentication, authorization, signing, validation, and other cybersecurity processes. A secret's risk metadata may indicate which controls protect the secret, the deployment scope of the secret or the asset it secures, known exposures of the secret, whether the secret secures other secrets, the impact if the secret is misused, the secret's strength, characteristics of the asset the secret secures, the secret's risk history, and other characteristics of secrets that set them apart. Unlike secrets, typical user-generated digital assets like web pages, documents, image files, and so on have value on their own. An enhanced system distinguishes between secrets and non-secrets when modulating access, making it possible to automatically provide consistent, efficient, and effective risk-based control over access to secrets.

Abstract: In some aspects, the techniques described herein relate to a system, including: a processor-implemented module configured to provide a business-to-business marketplace, wherein the processor-implemented module is first configured to filter potential resellers by industry type such that potential sellers are only able to conduct business on the business-to-business marketplace with potential resellers in a common industry, and wherein the processor-implemented module is second configured to allow a potential seller to filter potential resellers based one or more of (1) a plurality of predefined potential reseller verification tiers, wherein one of the potential reseller verification tiers is based on a physical inspection of the potential reseller, (2) a type of address of the potential reseller, (3) equipment of the potential reseller, or (4) a type of facility of the potential reseller.

Abstract: Global object access auditing techniques are described. In an implementation, a global SACL for a resource and an object SACL are merged to form a merged SACL responsive to a request for access to an object. The merged SACL is checked to determine what activity is to generate an audit event.

Abstract: An X-ray tube includes a target and a cathode assembly. The cathode assembly includes a first filament configured to emit a first beam of electrons toward the target, a first gridding electrode coupled to the first filament, a second filament configured to emit a second beam of electrons toward the target, and a second gridding electrode coupled to the second filament.

Abstract: An x-ray tube includes a vacuum chamber, a cathode positioned within the vacuum chamber and configured to emit electrons, and an anode positioned within the vacuum chamber to receive the electrons emitted from the cathode and configured to generate a beam of x-rays from the electrons. The x-ray tube further includes a window positioned to pass the beam of x-rays therethrough, an electron collector structure having an aperture formed therein to allow passage of x-rays therethrough, and a layer attached to the electron collector structure and configured to at least partially absorb or reduce diffraction of x-rays that contact the layer.
