  • Patent number: 11818572
    Abstract: Multiple authenticated identities for a single wireless association may be provided. First, an Access Point (AP) may provide an association with a client device. The AP may then establish, on the association, a first authenticated session for the client device based on a first media access control (MAC) address and a first identity. Next, the AP may establish, on same the association, a second authenticated session for the client device based on a second MAC address and a second identity.

  • Publication number: 20230188523
    Abstract: A method is provided to anonymize the media access control (MAC) address of a client device. The method involves generating a plurality of media access control (MAC) addresses for use by a client device in a network. Policies are defined that determine which one of the plurality of MAC addresses is to be used by the client device. The plurality of MAC addresses allocated for use by the client device are registered with a management entity in the network.

  • Patent number: 11277424
    Abstract: In one embodiment, a monitoring process identifies a set of counters maintained by a networking device by comparing a configuration of the networking device to an object relationship model. The monitoring process obtains counter values from the identified set of counters maintained by the networking device. The monitoring process detects an anomaly by using the obtained counter values as input to a machine learning-based anomaly detector. The monitoring process generates an anomaly detection alert for the detected anomaly.

  • Patent number: 10904217
    Abstract: A source virtual private network (VPN) gateway supports a local source subnet and communicates over a wide area network (WAN) with a destination VPN gateway that supports a local destination subnet. The source VPN gateway receives from the local source subnet an Internet Protocol (IP) packet destined for the local destination subnet, determines a security association (SA) based on a source IP address and a destination IP address of the IP packet, and encapsulates the IP packet with tunnel encapsulation including a tunnel protocol header and a tunnel outer IP header, to produce a clear-text tunnel packet. The source VPN gateway encrypts the IP packet and the tunnel protocol header but not the tunnel outer IP header using an encryption key and a security parameter index for the SA, to produce an encrypted tunnel packet, and tunnels it to the destination VPN gateway over the WAN.

  • Patent number: 10873455
    Abstract: Techniques are presented for encryption key rollover synchronization in a network. In one embodiment, a method includes generating a new set of public-key encryption keys for a first network element. Based on the new set of public-key encryption keys, a set of new security associations between the first network element and each other network element in the network is generated. The method includes providing a new public key from the new set of public-key encryption keys to a network controller and using security associations associated with a previous set of public-key encryption keys for encrypted communication between the first network element and each other network element. Upon obtaining, from a second network element, traffic protected by a security association from the set of new security associations, the method includes using the new security associations for subsequent encrypted communication between the first network element and the second network element.

  • Patent number: 10778775
    Abstract: Presented herein are techniques in which one or more network devices can use information provided by a special purpose network connected device to retrieve a usage profile (i.e., configuration file) associated with the special purpose network connected device. The retrieved usage profile, which includes/describes preselected (predetermined) usage descriptions associated with the special purpose network connected device, can then be used to configure one or more network devices. For example, the predetermined usage descriptions associated with the special purpose network connected device can be instantiated and enforced at a network device or the predetermined usage descriptions can be used for auditing the special purpose network connected device (e.g., monitoring of traffic within the network).

  • Patent number: 10595320
    Abstract: A process for implementing temporary rules for network devices is described. In one embodiment, the process includes a controller receiving a manufacturer usage description (MUD) identifier from a first device. The controller retrieves a MUD file associated with the MUD identifier. The controller registers a device identifier associated with the first device with a delegated controller determined based on the MUD file. The delegated controller is configured to generate a dynamic policy for the first device. The controller receives a dynamic policy from the delegated controller for the first device. The dynamic policy may be configured to permit a communication session between the first device and a second device. The controller forwards the dynamic policy to an access control device in communication with the first device to enable the access control device to permit the communication session between the first device and the second device.
