  • Publication number: 20230254325
    Abstract: Utilities (e.g., methods, systems, apparatuses, etc.) for use in generating and making use of priority scores for data generated by one or more data systems that more accurately prioritize those events and other pieces of data to be addressed by analysts and troubleshooters before others (e.g., collectively taking into account threats posed by origin host components and risks to impacted host components) to work the highest risk events and alarms first and to effectively and efficiently spend their alarm monitoring time.

  • Publication number: 20230000321
    Abstract: Provided herein are imaging systems for a patient including an imaging probe and an imaging assembly. The imaging probe includes: an elongate shaft with a proximal end, a distal portion, and a lumen extending between the proximal end and the distal portion; a rotatable optical core with a proximal end and a distal end, and at least a portion of the rotatable optical core is positioned within the lumen of the elongate shaft; and an optical assembly positioned proximate the distal end of the rotatable optical core, the optical assembly configured to direct light to tissue to be imaged and collect reflected light from the tissue to be imaged. The imaging assembly is constructed and arranged to optically couple to the imaging probe. The imaging assembly is configured to emit light into the imaging probe and receive the reflected light collected by the optical assembly.

  • Publication number: 20200125725
    Abstract: Utilities for data network monitoring for identification of security threats and other occurrences of interest and analytical tools for selecting actions to be taken to reduce further harm or vulnerability. Log message data (e.g., log messages, alerts, etc.) may be enriched with supplemental information related to an identity (e.g., user) that is not initially present in the log message data, but which may be beneficial in generating events and identifying appropriate response actions.
