  • Publication number: 20260222385
    Abstract: Aspects of the present disclosure are directed to enabling, in an environment in which multiple Access Points (APs) with varying privacy and Randomized and Changing MAC (RCM) configurations operate, AP-to-AP RCM in conjunction with Multi-Access Point Coordination (MAPC) between the APs without one adversely affecting the other. In one aspect, a first access point (AP) may determine a Media Access Control (MAC) rotation strategy for a first plurality of access points (APs) of a first wireless network. The MAC rotation strategy may specify use of Basic Service Set Identifiers (BSSIDs) by the first plurality of APs for implementing RCM in presence of a second plurality of APs of a second wireless network. The first AP may perform the RCM based on the MAC rotation strategy. The first AP may perform multi-AP coordination with the second plurality of APs using the BSSIDs.

  • Patent number: 12696170
    Abstract: A network function orchestrator (NFO) of a local area network (LAN) controller can configure multiple different tunnel endpoints in the LAN based on network traffic observed within the LAN. The NFO can monitor network traffic communicated from client devices and through access points in the LAN. The network traffic can be associated with multiple different destinations. The NFO can determine, based on the network traffic and using network topology data, network devices to serve as tunnel endpoints within the LAN. Different tunnel endpoints can be configured for use in connection with different traffic destinations. The NFO can communicate with the network devices and the access points to configure the LAN to use the different tunnel endpoints.

  • Patent number: 12688103
    Abstract: The present technology automates the process of collecting and using data from IoT devices to improve IoT security and management while limiting the manual entry requirements of conventional IoT platforms. The technology receives data from IoT devices and determines behavioral characterizations of the IoT devices based on the data. The technology then uses a generative model to create a file representative of the behavioral characterizations of the IoT device, and uses that file to represent new IoT devices with similar attributes to those represented by the file. In doing so, the technology can improve security by, for example, creating a MUD file representative of a new IoT device with no associated MUD file. The technology can also create a file representative of the IoT device to improve onboarding of an IoT device in, for example, an IoT operations dashboard.

  • Publication number: 20260194887
    Abstract: In one embodiment, a device associates available 5G functions with contextual information, wherein the contextual information maps each of the available 5G functions to a segment identifier of a security model topology for a segmented network within which that available 5G function is deployed. The device receives a request from a user equipment endpoint to communicate via the segmented network. The device selects a particular user plane function from among the available 5G functions for use by the user equipment endpoint based in part on the segment identifier of the security model topology mapped to the particular user plane function. The device causes the user equipment endpoint to communicate via the segmented network using the particular user plane function.

  • Patent number: 12664502
    Abstract: Techniques are described herein for managing access to remotely accessed software applications. In embodiments, such techniques may be performed by a service provider platform for software applications capable of being accessed by computing devices. The techniques may involve determining (e.g., based on a software bill of materials) components associated with the software applications, identifying a number of current security threats, and determining, based on the components and current security threats, a risk score associated with each of the software applications. The service provider platform may receive an indication of a level of risk for each of the computing devices in the organization, generate, based on the risk score associated with the software applications and the level of risk for each of the computing devices, policy data for each of the computing devices, and provide the policy data to at least one second computing device.

  • Publication number: 20260163872
    Abstract: The present technology provides a group encryption key for a ring as a whole within a ring-based topology. The key can, for example, be managed by a central Key Server (KS) that then transmits the key and a group encryption tag to nodes on the ring. For example, the ring edge node can encode a tag into a header of a frame so that the tag functions as a group-based tag. Future nodes on the ring network can then avoid the burdensome decryption and encryption steps of the prior art peer-to-peer encryption and decryption process.

  • Patent number: 12652211
    Abstract: Techniques for mitigating network failures (e.g., SLA violations, service degradations, network outages, etc.) based on output(s) from a predictive network system. The techniques may include determining that a failure is predicted to occur in a network and determining a correlation between the failure and a previous failure that occurred in the network. In examples, the correlation may be determined using a machine-learned model. The techniques may also include determining, based at least in part on the correlation, a condition contributing to the failure. In this way, prior to occurrence of the failure, a parameter associated with the network may be altered based at least in part on the condition to mitigate or otherwise prevent the failure.

  • Patent number: 12652578
    Abstract: This disclosure describes techniques for predicting and accommodating for outages in a satellite network using crowdsourced data. An example method includes receiving outage data indicating first outages experienced by first endpoints in a first geographical region. The first outages, for instance, include interruptions in communication between first satellites and the first endpoints. The example method further includes predicting, based on the outage data, a second outage comprising an interruption in communication between at least one second satellite and a second endpoint in a second geographical region. Further, the example method includes causing the second endpoint to transmit user data over a secondary network in advance of the second outage.

  • Patent number: 12647777
    Abstract: In one illustrative example, a controller may operate to send a request message towards a user equipment (UE) which operates to communicate traffic in a session in a mobile network. In response, the controller may receive, from a user plane function which anchors the session of the UE, a response message which includes an identifier of the user plane function. The controller may verify whether a zone or security level value that is assigned to the user plane function matches a zone or security level value that is assigned to the UE. If the controller identifies a discrepancy between the zone or security level values, the controller may provide a notification indication to indicate the discrepancy. The UE may be an industrial Internet of Things (IIoT) device and the zone or security level values may be based on International Electrotechnical Commission (IEC) 62443.

  • Patent number: 12639450
    Abstract: The present technology monitors the behavior and security profile of an IoT device and determines the changes that need to be made to the MUD file of the IoT device based on the data gathered during the monitoring. The technology then creates a new MUD file using a generative model (such as a large language model (LLM)) and compares the new MUD file with the original MUD file. Thereafter, the technology can communicate with the IoT device manufacturer to provide the new MUD file and explain the reasons why it is advantageous over the original MUD file. The new MUD file can then be deployed by the manufacturer to resolve security and efficiency issues with ease.
