Abstract: Disclosed below are representative embodiments of methods, apparatus, and systems for managing one or more cybersecurity tools that are deployed to help protect electronic assets in an IT infrastructure—including, for example, one or more security configuration management tools, vulnerability management tools, event logging tools, or other IT infrastructure security or monitoring tools that are used to monitor, secure, and/or control assets in an IT infrastructure. In one example, a request to install local software for access to a remote security control service is received from a remote user at a remote device; and data for installing the local software is transmitted to the remote user. In certain implementations, the data for installing the local software further includes a public cryptographic certificate.

Abstract: This invention relates to methods for determining whether or not to discard a sample of oil based on the presence of polar compounds in the oil and devices to be used therewith. In a preferred embodiment a test strip comprising an adsorbent affixed to a backing is spotted with a polar indicator. A sample of oil is positioned on a heat conducting device supporting the test strip and the oil is allowed to migrate over the adsorbent material thereby displacing the polar indicator in an amount related to the amount of polar compounds in the oil. This displacement is correlated to the amount of polar compounds in the sample.
