Filed:

Jul 8, 2019

Appl. No.:

16/505690

Inventors:

- Culver City CA, US
David Bigelow - Upton MA, US
Nicholas J Witchey - Laguna Hills CA, US
Chad Milam - Los Angeles CA, US

International Classification:

G06K 7/10
H04L 12/24
H04L 12/26

Abstract:

An asset management system comprises a memory storing software instructions enabling control of a set of network devices having a corresponding allocated rack space, the set being sparsely distributed over multiple cabinets, wherein an aggregate rack space occupied by the set of network devices does not exceed the allocated rack space. A processor coupled with the memory and that executes, based on the software instructions stored in the memory, operations comprising generating a virtual representation representing the set of network devices residing in at least one virtual cabinet corresponding to the allocated rack space. The virtual representation is used to enable configuration of a functionality of at least one network device in the set of network devices residing in the virtual cabinet based on asset data of the at least one network device.

International Classification:

H04L 29/06

Abstract:

System and methods for communicating across a network comprise: a database containing high level security rules for the network; computing devices communicating on the network; a security rule translation module; event sensors configured to monitor and detect one or more events occurring on or relating to the network, and in response thereto, provide to the security rule translation module an indication of occurrence for each of the one or more security events. The security rule translation module may associate the security rules with the security events corresponding to the received indication, and produce a low-level security rule based on data from the high-level security rule and the received indication of occurrence of the security events. The system may also include switches coupled to receive the low-level security rules from the security rule translation module and enforce the low-level security rules on the network.

International Classification:

G06K 7/10

Abstract:

An asset management system comprises a control function module configured to manage a set of rack-mounted devices having a corresponding allocated rack space when the devices are sparsely distributed over multiple cabinets, possibly in different data centers. The aggregate rack space occupied by the set of devices does not exceed the allocated rack space. A user interface is communicatively coupled to the control function module and configured to generate a virtual representation visible to a user of the set residing in a virtual cabinet corresponding to the allocated rack space. The user interface includes a user control to enable the user to interact with the set of devices. The asset location system can comprise a radio frequency identification (RFID) system to locate and track the devices, and select a subset of the devices to display and control based on filter parameters.

Abstract:

A method for timely address space randomize includes loading a code region from a program binary to a first location within the address space, detecting, during execution of the program, an output-input call pair from the program and, in response to detecting the output-input call pair from the program: selecting a second location within the address space to move the code region to, determining memory locations of one or more references to the code region, updating the values of the references in memory based on the second location and using annotation information within the program binary, and moving the code region to the second location within the address space.
