Publication number: 20180196956Abstract: A security architecture and method for a system on a chip or a microcontroller. The method in one embodiment includes a first central processing unit (CPU) specifying a first address. A security attribute for the first address is identified, wherein the security attribute is one of at least four security attributes. The first CPU can be denied access to a memory location identified by the first address based on the identified security attribute.Type: ApplicationFiled: January 10, 2018Publication date: July 12, 2018Inventor: Sudhin Mishra

Publication number: 20170302585Abstract: According to certain non-limiting embodiments disclosed herein, the functionality of a server is extended with a mechanism for identifying connections with clients that have exhibited attack characteristics (for example, characteristics indicating a DoS attack), and for transitioning internal ownership of those connections such that server resources consumed by the connection are reduced, while keeping the connection open. The connection thus moves from a state of relatively high resource use to a state of relatively low server resource use. According to certain non-limiting embodiments disclosed herein, the functionality of a server is extended by enabling the server to determine that any of a client and a connection exhibits one or more attack characteristics (e.g., based on at least one of client attributes, connection attributes, and client behavior during the connection, or otherwise). As a result of the determination, the server changes its treatment of the connection.Type: ApplicationFiled: March 18, 2017Publication date: October 19, 2017Applicant: Akamai Technologies, Inc.Inventors: Sudhin Mishra, Stephen L. Ludin, John A. Dilley, Erik Nygren, Philip Lisiecki, Karl-Eliv J. Hallin, Joshua Hunt

Patent number: 8875287Abstract: According to certain non-limiting embodiments disclosed herein, the functionality of a server is extended with a mechanism for identifying connections with clients that have exhibited attack characteristics (for example, characteristics indicating a DoS attack), and for transitioning internal ownership of those connections such that server resources consumed by the connection are reduced, while keeping the connection open. The connection thus moves from a state of relatively high resource use to a state of relatively low server resource use, and the server is able to free resources such as memory and processing cycles previously allocated to the connection. In some cases, the server maintains the connection for at least some time and uses it to keep the client occupied so that it cannot launch—or has fewer resources to launch—further attacks, and possibly to gather information about the attacking client.Type: GrantFiled: March 15, 2013Date of Patent: October 28, 2014Assignee: Akamai Technologies, Inc.Inventors: Stephen L.
