Abstract: A method of controlling the dissemination of sensitive information appearing in an image to be sent via electronic communication. The method includes determining a probability that an image selected to be sent with an electronic message includes sensitive information, and in response to the probability exceeding a predetermined threshold, applying a control measure to the image.

Abstract: Methods are provided for determining decay rates and/or shelf-lives of intellectual capital (IC) detected issues for only performing actions for expired or about to expire IC detected issues. Specifically, the methods involve performing one or more data collections that include data relating to one or more of a configuration of a computing system or an operation of the computing system and detecting an issue in the computing system based on the data. The issue relates to an anomaly in one or more of the configuration of the computing system or the operation of the computing system. The methods further involve determining a shelf-life for the issue, where the shelf-life indicates an estimated duration of the issue existing in the computing system before redetecting whether the issue is still present and adjusting a next data collection of the one or more data collections based on the shelf-life of the issue.

Abstract: Techniques for an email-security system to screen emails, extract information from the emails, analyze the information, assign probability scores to the emails, and classify the emails as likely fraudulent or not. The system may analyze emails for users and identify fraudulent emails by analyzing the contents of the emails. The system may evaluate the contents of the emails to determine probability score(s) which may further determine an overall probability score. The system may then classify the email as fraudulent, or not, and may perform actions including blocking the email, allowing the email, flagging the email, etc. In some instances, the screened emails may include legitimate brand domain addresses, names, images, URL(s), and the like. However, the screened emails may contain a reply-to domain address that matches a free email service provider domain. In such instances, the email-security system may assign a probability score indicative that the screened email is fraudulent.

Abstract: This disclosure describes techniques to operate a control plane in a network fabric. The techniques include determining a stateless rule corresponding to communication between a first segment of the network fabric and a second segment of the network fabric. The techniques further include configuring the control plane to enforce the stateless rule.

Abstract: Intelligent distribution of packet flows may be provided. Compute resource data may be received. Next, packets may be classified into flows that may be persistently mapped to compute resources for a lifetime of the flows. Based on the compute resource data, the flows may then be allocated to the compute resources.

Abstract: Embodiments relate to a method for enhancing and prioritizing operation technology (OT) control systems in a safety instrumented system (SIS) environment by incorporating safety levels. The method includes receiving network packets associated with OT systems by network interface. From network packets, OT systems associated with safety integrity level (SIL) values are identified. In response to identifying OT control systems associated with SIL values, determining priority levels from SIL values of OT systems. The method includes identifying, among OT control systems, network packets associated with a critical OT system associated with a SIL value having a higher priority level. The critical OT system may be prioritized that comprises encoding the network packets of the critical OT system, with corresponding SIL value. The prioritized critical OT system may be prioritized based on SIL value and classified into a network group associated with a network tag to deliver traffic with higher priority.

Abstract: Techniques for using Home Addresses, Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to obfuscate server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a Home Address that is mapped to the client device and at least one server IP address of the endpoint device. In this way, IP addresses of servers are obfuscated by a network mapping of the Home Addresses and the server IP addresses. The client device may then communicate data packets to the server using the Home Addresses as the destination address, and a virtual network service that works in conjunction with DNS can encapsulate the data packet with the server IP addresses and forward the data packet onto the server.

Abstract: Systems and methods are provided for re-balancing and healing of an SD-WAN in an unbalanced state and/or experiencing one or more failure states. In response to a request to connect to a new controller resulting from OMP load shedding from a first controller, the system can identify other controllers capable of handling the load requirements of the edge router. The system can incorporate the controller group preference of the edge router and select a second controller based on the identified other controllers and within the preferred controller group. If not possible, the system can temporarily assign the edge router to non-preferred controller groups and move them back to controllers in the preferred controller group once it becomes viable. The system further enhances OMP graceful restart (GR) logic to incorporate the load shedding effect and avoid unnecessary route retention that GR entails.

Abstract: A voltage-controlled oscillator (VCO) is disclosed that includes an inductor-capacitor (LC) tank coupled with a first voltage supply node, a pair of cross-coupled transistors that are coupled with the LC tank and coupled with each other at a tail node, and a high-frequency current return path to the first voltage supply node. The high-frequency return path includes a first decoupling capacitor coupled with the first voltage supply node and a second voltage supply node, and a first inductor coupled with the tail node and the second voltage supply node. The first inductor is formed as a first conductive trace and has a quality factor (Q) value of 25 or greater.

Abstract: A network element in a quantum network receives a hybrid frame including a classical header and a quantum payload. The network element processes the classical header for a length of time and generates a new classical header. The network element drops a portion of the quantum payload based on the length of time spent processing the classical header and updates the hybrid frame to include the new classical header and the quantum payload without the dropped portion.
