Abstract:
Patterns can be discovered in security events collected by a network security system (10). In one embodiment, the present invention includes collecting and storing security events from a variety of monitor devices (12).In one embodiment , a subset of the stored security events is provided to a manager (14) as an event stream. In one embodiment, the present invention further includes the manager discovering one or more previously unknown event patterns in the event stream.
Abstract:
Disclosed herein is a neuromorphic percolating network (100). The network comprises a substrate (102) having at least two electrical contacts (104A, 104B); a plurality of nanoparticles (106, 108, 100) distributed on the substrate (102), at least some of the nanoparticles positioned between at least two of the at least two electrical contacts, the surface coverage of the nanoparticles within a tolerance of a percolation threshold; and at least one memristive element (116) located at least partially in a gap between nanoparticles, or groups of nanoparticles, that are not otherwise directly connected to each other, the memristive element(s) at least partially providing at least one persistent pathway (118,120) of increased activity. Disclosed herein are methods for fabricating a neuromorphic percolating network or component thereof, and neuromorphic percolating networks formed by such methods.
Abstract:
A session table includes one or more records, where each record represents a session. Session record information is stored in various fields, such as key fields, value fields, and timestamp fields. Session information is described as keys and values in order to support query/lookup operations. A session table is associated with a filter, which describes a set of keys that can be used for records in that table. A session table is populated using data contained in security information/events. Rules are created to identify events related to session information, extract the session information, and use the session information to modify a session table. A session table is partitioned so that the number of records in each session table partition is decreased. A session table is processed periodically so that active sessions are moved to the current partition.
Abstract:
Systems and methods are provided for determining data center cooling and power requirements and for monitoring performance of cooling and power systems in data centers. At least one aspect provides a system and method that enables a data center operator to determine available power and cooling at specific areas and enclosures in a data center to assist in locating new equipment in the data center.
