Patent number: 11418513Abstract: A system for controlling accesses to network enabled devices includes a network interface over which a hub communicates with network enabled devices, a processor, and a multilayer access control layer. The access control layer includes instructions that, when executed by the processor, cause the processor to detect, at the hub, a request representing an attempt by an application executing on a remote host device to access a network enabled device communicatively coupled to the hub, characterize the request according to a user of the remote host device, the application making the attempt, and the network enabled device, and determine whether to allow or deny the request based upon the characterization and a plurality of rules. The rules may include definitions of access rights, with respect to the network enabled device, for users, applications, commands or queries made by applications, remote host devices, and network domains.Type: GrantFiled: July 31, 2020Date of Patent: August 16, 2022Assignee: McAfee, LLCInventors: Himanshu Srivastava, Dattatraya Kulkarni, Srikanth Nalluri, Krishnapur N.

Patent number: 9817843Abstract: In an example, one or more computing devices operate to provide a context-aware reputation of a place, such as in relation to a human user. Context may include the user's identity and purpose, as well as environmental factors such as time of day, weather, and political drivers. The device may communicate with a server to receive globalized safety intelligence. When the user enters a zone, the device may determine a context-sensitive reputation, such as “Green,” “Yellow,” or “Red.” Depending on the reputation, the device may then take an appropriate action, such as warning the user or providing additional information.Type: GrantFiled: September 26, 2014Date of Patent: November 14, 2017Assignee: McAfee, Inc.Inventors: Joydeb Mukherjee, Saravana Kumar Subramanian, Raj Vardhan, Rangaswamy Narayana, Shankar Subramanian, Dattatraya Kulkarni, Javed Hasan
