Publication number: 20220336290Abstract: A cloud security service provides network security. The cloud security service receives, via a computer network, an electronic message sent by a sending user of an enterprise to a receiving user. The cloud security service analyzes the electronic message using a machine-learned user model describing the sending user's electronic messages, the user model generated based at least in part on previous electronic messages sent by the sending user. The cloud security service determines, based on the analysis, that the electronic message violates a security policy of the enterprise. The cloud security service performs a security action based on the determination that the electronic message violates the security policy.Type: ApplicationFiled: May 2, 2022Publication date: October 20, 2022Inventors: Chetan Anand, Arjun Sambamoorthy, Anand Raghavan, Dhananjay Sampath

Patent number: 11356482Abstract: A cloud security service receives an electronic message sent by a purported sending user to a receiving user. The cloud security service retrieves a user model and a user identity associated with the purported sending user, the user identity including a set of feature values describing messages from the purported sending user. The cloud security service applies the user model to the received electronic message to identify a set of feature values describing the electronic message. The cloud security service compares the set of feature values describing the electronic message to the set of feature values describing messages from the purported sending user included in the user identity. The cloud security service determines, based on the comparison, whether the received electronic message was sent by the purported sending user. The cloud security service performs a security action based on the determination.Type: GrantFiled: November 27, 2018Date of Patent: June 7, 2022Assignee: ArmorBlox, Inc.Inventors: Chetan Anand, Arjun Sambamoorthy, Anand Raghavan, Dhananjay Sampath

Patent number: 10397255Abstract: A server has a processor and a memory connected to the processor. The memory stores instructions executed by the processor to collect operating signals from machines, where each operating signal characterizes the state or a change in operational state of a designated application operating within a designated container, where the designated container is an isolated process in user space designated by an operating system kernel. The operating signals are compared to models that incorporate summarizations of data sets that represent observed benign operating signals and malicious operating signals for the designated application operating within the designated container. Risks associated with the operating signals are characterized.Type: GrantFiled: September 22, 2016Date of Patent: August 27, 2019Assignee: StackRox, Inc.Inventors: Sameer Bhalotra, Ali Golshan, Dhananjay Sampath, Vishwanath Raman

Patent number: 8738906Abstract: A system may identify one or more attributes associated with traffic. The system may then determine that at least one attribute, of the one or more attributes, matches an attribute of a set of attributes that correspond to a set of categories of traffic. Based on determining that the at least one attribute matches the attribute of the set of attributes, the system may identify a category, of the set of categories, that corresponds to the attribute. The system may associate the category with the traffic, and process the traffic based on the associated category.Type: GrantFiled: November 30, 2011Date of Patent: May 27, 2014Assignee: Juniper Networks, Inc.Inventors: Dhananjay Sampath, Chetan Anand, Arjun Sambamoorthy, Anand Deshpande
