Abstract: Various embodiments are directed to a system and method for establishing a secure communication pathway between a network-connected device and a computing platform. Such configurations encompass encrypting a device-specific installation package passed to the device using a device-generated cryptography key, verifying the identity of the computing platform at the device, encrypting a response message via a platform-generated cryptography key, transmitting the response message to the computing platform, verifying characteristics of the device via the response message, and establishing a secure communication platform upon verification of the device.

Abstract: Identity information is decoupled from reachability information in packets transferred between hosts of a computer network by replacing forwarding information within said packets with an identifier having a format of the forwarding information, and applying forwarding labels, derived from the identifiers, which are then used in lieu of the forwarding information for conveying the packets within the network. During such conveyance, the packets are treated according to one or more policies prescribed on a basis of the identifier, which may be an IPv6 address. The forwarding labels may be MPLS labels.

Abstract: A system comprises an enterprise network system and engine that could be inside an enterprise or hosted on a public and/or private cloud infrastructure. The engine has a discovery module coupled to a switch device, an AI and machine learning based monitoring and detection module coupled to the switch device and end point devices or assets including laptops, workstations and servers, and a remediation module coupled to the switch device. The system provides processes for building a network endpoint state transition model. The system can be unsupervised and is completely based on artificial intelligence processes. The network endpoint model is constructed by using a network identity and network behavior observed through data traffic flow to capture co-occurrence of data communications or connections in at least two consecutive observation windows or time frames. This network endpoint connection state transition model is used for detecting behavior anomalies.

Abstract: To determine whether an IoT system connected with a network environment (e.g., the internet) is compromised, a networked Trust as a Service (TaaS) server receives system data indicative of various characteristics of the IoT system, wherein the system data is harvested by a software agent installed on the IoT system. The TaaS server initially establishes a baseline characteristics profile for the IoT system, such that subsequently received system data from the software agent may be compared against the baseline characteristics profile to quickly identify discrepancies between the originally established baseline characteristics profile and current operating characteristics of the system. Such discrepancies may be caused by desirable software updates, in which case the discrepancies may be integrated into the baseline characteristics profile, or the discrepancies may result from the IoT system being undesirably compromised.

Abstract: Disclosed herein are methods of forwarding data over an IP network. The methods may include receiving a packet from a source host connected to the IP network, identifying the IP address of a destination host designated in the packet, determining the location on the IP network where the destination host designated by the packet is connected, without reference to the MAC address specified in the packet, by using location-identification information stored on the IP network, and forwarding the packet to the location on the IP network where the destination host is connected without reference to the MAC address specified in the packet. Also disclosed herein are related network devices implementing such techniques and operations, as well as IP networks which include such network devices.

Abstract: Disclosed are systems, methods, and computer-readable storage media for guaranteeing symmetric bi-directional policy based redirect of traffic flows. A first switch connected to a first endpoint can receive a first data packet transmitted by the first endpoint to a second endpoint connected to a second switch. The first switch can enforce an ingress data policy to the first data packet by applying a hashing algorithm to a Source Internet Protocol (SIP) value and a Destination Internet Protocol (DIP) value of the first data packet, resulting in a hash value of the first data packet. The first switch can then route the first data packet to a first service node based on the hash value of the first data packet.

Abstract: Providing an objective measure of trust in data provided by an Industrial Internet of Things (IIoT) device utilizes an objective trust indicator generated based at least in part on baseline device characteristics and corresponding monitored/observed device characteristics. These device characteristics may comprise device hardware characteristics, device software characteristics, application software characteristics (of software installed on the device), and/or device behavior characteristics. The trust indicator is determined by comparing a match vector indicative of weighted scores for the baseline device characteristics relative to a generated monitored characteristics vector indicative of differences between baseline and monitored device characteristics, and determining a directional difference between the match vector and the monitored characteristics vector.
