Patent number: 11966463Abstract: A policy interpreter detects that an application container has been added in a container system, and opens a stored manifest for the application container. The policy interpreter retrieves running services information regarding the application container, and generates a security policy for the application container. The security policy defines a set of actions for which the application container can perform, and the set of actions are determined using the manifest and the running service information associated with the application container. The policy interpreter loads the security policy at a security container. The security container blocks an action performed by the application container in response to determining that the action performed by the application container does not match any action in the set of actions defined in the security policy. The policy interpreter transmits the security policy to a graphical user interface container for presentation to a user via a display device.Type: GrantFiled: January 14, 2022Date of Patent: April 23, 2024Assignee: SUSE LLCInventors: Glen K. Kosaka, Gang Duan, Fei Huang

Publication number: 20240086521Abstract: A threat level analyzer probes for one or more threats within an application container in a container system. Each threat is a vulnerability or a non-conformance with a benchmark setting. The threat level analyzer further probes for one or more threats within a host of the container service. The threat level analyzer generates a threat level assessment score based on results from the probing of the one or more threats of the application container and the one or more threats of the host, and generates a report for presentation in a user interface including the threat level assessment score and a list of threats discovered from the probe of the application container and the host. A report is transmitted by the threat level analyzer to a client device of a user for presentation in the user interface.Type: ApplicationFiled: November 21, 2023Publication date: March 14, 2024Applicant: SUSE LLCInventors: Henrik Rosendahl, Fei Huang, Gang Duan

Publication number: 20240088972Abstract: Aspects presented may enable RF sensing to be adaptive to the environment to improve the sensing, performance, and/or the spectrum efficiency of cellular systems and the power efficiency of RF sensing nodes. In one aspect, an RF sensing node extracts one or more features for a set of objects of an area via at least one non-RF sensor. The RF sensing node transmits, to a network entity, the one or more features or at least one non-RF measurement derived from the one or more features. The RF sensing node receives, from the network entity, an RRS transmission configuration derived based on the one or more features or the at least one non-RF measurement transmitted to the network entity.Type: ApplicationFiled: November 6, 2023Publication date: March 14, 2024Inventors: Weimin DUAN, Fei HUANG
