Abstract: Embodiments identify a station that rotates an over the air station address. As address rotation was not originally designed into wireless networks, the rotation can introduce communication challenges for the station. The embodiments derive that traffic referencing two different over the air station addresses are associated with a single common station. This is accomplished by determining a similarity between properties of two sets of traffic. A first set of traffic references the first over the air station address and a second set of traffic references the second over the air station address. If the properties common across the two sets of traffic indicate sufficient similarity, the embodiments determine that both sets of traffic are associated with a single device. Network configuration of the device is then adjusted based on the determination.

Abstract: To improve adaptation of network infrastructure to address rotations performed by wireless client device, embodiments provide for an exchange of a stable machine identifier (SMI) between a network access device and an authentication service. Some embodiments define a new SMI attribute that is included in a authentication service access-request and/or access-accept message. When a network access device obtains an SMI for a particular wireless client device, the network access device passes the SMI to the authentication service. Similarly, if an authentication service obtains a SMI value for a wireless client device, this information is provided to a network access device.

Abstract: Techniques are presented herein for engagement and disengagement of Transport Layer Security proxy services with encrypted handshaking. In one embodiment, a first initial message of a first encrypted handshaking procedure for a first secure communication session between a first device and a second device is intercepted at a proxy device. The first initial message includes first key exchange information for encrypting the first encrypted handshaking procedure. A copy of the first initial message is stored at the proxy device. A second initial message of a second encrypted handshaking procedure for a second secure communication session between the proxy device and the second device is sent from the proxy device to the second device. The second initial message includes second key exchange information for encrypting the second encrypted handshaking procedure. The proxy device determines, based on the second encrypted handshaking procedure, whether to remain engaged or to disengage.

Abstract: Systems, methods, and computer-readable media for assessing reliability and trustworthiness of devices across domains. Attestation information for an attester node in a first domain is received at a verifier gateway in the first domain. The attestation information is translated at the verifier gateway into translated attestation information for a second domain. Specifically, the attestation information is translated into translated attested information for a second domain that is a different administrative domain from the first domain. The translated attestation information can be provided to a verifier in the second domain. The verifier can be configured to verify the trustworthiness of the attester node for a relying node in the second domain by identifying a level of trust of the attester node based on the translated attestation information.

Abstract: A trained model may be deployed to an Internet-of-Things (IOT) operational environment in order to ingest features and detect events extracted from network traffic. The model may be received and converted into a meta-language representation which is interpretable by a data plane engine. The converted model can then be deployed to the data plane and may extract features from network communications over the data plane. The extracted features may be fed to the deployed model in order to generate event classifications or device state classifications.

Abstract: In one embodiment, a gateway device receives, from a centralized broker device, a data-access policy for a given computer network, the data-access policy defining which of one or more accessing entities are granted access to specific elements of data within the given computer network. When the gateway device then receives, from a particular accessing entity, a request for one or more particular elements of data from within the given computer network, it may determine, based on the data-access policy, whether the particular accessing entity has been granted access to each of the one or more particular elements of data of the request. As such, the gateway device may prevent access for the particular accessing entity to any of the one or more particular elements of the data request to which the particular accessing entity has not been granted access.

Abstract: In one embodiment, functionality is disclosed for commissioning a target device based, at least in part, on providing identifying information that identifies a target device, where that identifying information is configured to be included in a request for authorization to commission the target device, and that request for authorization to commission the target device comprises one or more requested commissioning actions; receiving a commissioning authorization, where the commissioning authorization comprises information regarding one or more authorized commissioning actions for which a license is available, where the one or more authorized commissioning actions were selected from among the one or more requested commissioning actions; and performing the one or more authorized commissioning actions.

Abstract: In accordance with one aspect, presented herein is a method to encrypt beacon device telemetry broadcast packets while respecting the low power and low processing requirements inherent to wireless beacon devices and various other challenges which such an encryption scheme brings. In accordance with another aspect, a methodology is provided through which the network can identify if an unauthorized connection is being established with a beacon device and thereby prevent potential beacon device tampering.

Abstract: In one embodiment, a processor of a vehicle predicts a state of the vehicle using a behavioral model. The model is configured to predict the state based in part on one or more state variables that are available from one or more sub-systems of the vehicle and indicative of one or more physical characteristics of the vehicle. The processor computes a representation of a difference between the predicted state of the vehicle and a measured state of the vehicle indicated by one or more state variables available from the one or more sub-systems of the vehicle. The processor detects a malicious intrusion of the vehicle based on the computed representation of the difference between the predicted and measured states of the vehicle exceeding a defined threshold. The processor initiates performance of a mitigation action for the detected intrusion, in response to detecting the malicious intrusion of the vehicle.

Abstract: Presented herein is a system, device and method that involve creating a policy model and policy rule structure for a policy enforcement point to support policies adapt to rapid changing external conditions in addition to traditional policies that are static. The system facilitates the use of attributes that are either or both dynamically (at run-time) created and/or defined as ephemeral. A new policy attribute may be created dynamically (at run-time). The policy attribute may be mapped as being static or ephemeral. The methodology further involves facilitating evaluation of an attribute as an atomic or programmed set of functions.

Abstract: In one example embodiment, a network-connected device provides or obtains one or more computer network communications protected by a key. The network-connected device determines a count of the one or more computer network communications according to one or more properties of the one or more computer network communications. Based on the count of the one or more computer network communications, the network-connected device computes an information entropy of the key. Based on the information entropy of the key, the network-connected device dynamically generates a predicted threat level of the key.
