Abstract: Aspects of the disclosure relate to assessing authorization control of application programming interfaces (APIs) for services and/or microservices. Implementations disclosed herein robustly identify APIs configured with sufficient authorization control and APIs configured with insufficient authorization control. As such, disclosed implementations streamline a secure software development life cycle. Operations performed in example implementations include obtaining an identity token from an identity management module and invoking an API with multiple queries. At least one of the queries includes payload values specific to an identity different than an identity represented by the identity token. Responses of the API to the multiple queries are used to determine whether the API is configured with sufficient authorization control, and based on the determination, various post-assessment operations can be performed.

Abstract: Multi-chamber devices of collecting particles in aquatic environments including an upper chamber serving as a particle interceptor chamber, a lower chamber serving as a particle accumulator chamber, and a valve assembly interposed between the upper and lower chambers are disclosed. Upon rotation of an indented valve body, particles in the upper chamber are transferred to the lower chamber and preserved for analysis. The valve assembly substantially reduces the presence of living organisms in particle samples and enhances the accuracy of passive vertical particle flux sampling techniques. A plurality of sample collection chambers may be provided to facilitate temporal resolution of vertical particle flux measurements during a single deployment period.
