  • Publication number: 20260034996
    Abstract: An “aggregator” controls the allocation of scarce resources among competing demands within a target machine-control environment. Multiple machine-learning agents are initiated, each with its own initial resource-utilization-optimization model based on a pre-trained model. The machine-learning agents receive resource-utilization information from within the target environment. They then use the received information to modify their models in order to more optimally utilize the scarce resources. Each agent sends a prediction, based on the agent's modified model, to the aggregator. The aggregator uses the predictions it receives to update its own model and uses that updated aggregator model to control, at least to some extent, the allocation of the scarce resources within the target environment.

  • Patent number: 10038703
    Abstract: Embodiments are disclosed for profiling network-level malicious activity. Profiling embodiments include observing malicious activity, representing such activity in accordance with a set of representative features, capturing temporal evolution of this malicious behavior and its dynamics, and using this temporal evolution to reveal key risk related properties of these networks. Embodiments are further disclosed addressing the connectedness of various networks and similarity in network-level maliciousness. Embodiments directed to similarity analyses include focusing on the notion of similarity—a quantitative measure of the extent to which the dynamic evolutions of malicious activities from two networks are alike, and mapping this behavioral similarity to their similarity in certain spatial features, which includes their relative proximity to each other and may be used to help predict the future maliciousness of a particular network.

  • Patent number: 9729558
    Abstract: Network security and robustness is analyzed by developing correlations among network maliciousness observations to determine attack susceptibility. Network traffic is analyzed at the autonomous system (AS) level, among connected Internet Protocol (IP) routing prefixes, to identify these observations. The traffic is monitored for any of a number of specified mismanagement metrics. Correlations among these metrics are determined and a unified network mismanagement metric is developed, indicating network susceptibility to potentially malicious attack.
