  • Patent number: 12255976
    Abstract: In one embodiment, Ethernet Virtual Private Network (EVPN) is implemented using Internet Protocol Version 6 (IPv6) Segment Routing (SRv6) underlay network and SRv6-enhanced Border Gateway Protocol (BGP) signaling. A particular route associated with a particular Internet Protocol Version 6 (IPv6) Segment Routing (SRv6) Segment Identifier (SID) is advertised in a particular route advertisement message of a routing protocol (e.g., BGP). The SID includes encoding representing a particular Ethernet Virtual Private Network (EVPN) Layer 2 (L2) flooding Segment Routing end function of the particular router and a particular Ethernet Segment Identifier (ESI), with the particular SID including a routable prefix to the particular router. The particular router receives a particular packet including the particular SID; and in response, the particular router performs the particular EVPN end function on the particular packet.

  • Patent number: 12256355
    Abstract: This technology allows time synchronization in wireless networks with mobile stations. A wireless network controller transmits instructions to access points (“APs”) within the wireless network to monitor transmissions for time synchronization. One or more second APs observe fine time measurement (“FTM”) exchanges between a first AP and a mobile station. A particular second AP determines whether to perform a time synchronization with the first AP based on the detection of the FTM exchange or a determination that the station is moving toward the second AP. For time synchronization, the second AP determines the time that the first AP transmitted the FTM exchange and the time of transmission from the first AP to the second AP. The second AP synchronizes a second AP clock to the summation of the time of the transmission of the FTM exchange and the time of transmission from the first AP to the second AP.

  • Patent number: 12255868
    Abstract: Techniques for leveraging efficient metadata communications to improve domain name system (DNS) security are described. The DNS service uses a hash value to uniquely identify a client, and detect any change in metadata in order to keep policies up-to-date for the client. In an example method a first DNS query for a client device is intercepted. A cryptographic hash function is applied to metadata associated with the client device to generate a hash value. The hash value is added to an additional records section of the first DNS query to generate a second DNS query. The second DNS query is transmitted to a DNS service. The metadata associated with the client device is transmitted to the DNS service on an out-of-band encrypted channel. A DNS response, including the hash value, is received from the DNS service and transmitted to the client device.

  • Patent number: 12250215
    Abstract: This disclosure describes techniques for device to device authentication. For instance, a first device may detect a second device, such as when a user physically attaches the second device to the first device or when the second device wireless communicates with the first device. A component of the first device and/or an authentication entity may then determine to authenticate the second device. In some instances, the component determines to authenticate the second device using information associated with an environment of the second device. To authenticate the second device, the authentication entity may send a request to a user, receive a response from the user, and then verify the response. After the authentication, the first device may determine that the second device includes a trusted device and establish a connection with the second device.

  • Patent number: 12244616
    Abstract: This disclosure describes techniques for identifying the criticality of an asset in a network. In an example method, a first security metric of a first asset in a network, as well as network data that identifies data flows associated with a second asset in the network are identified. The second asset is a nearest neighbor of the first asset in the network. The method includes determining, based on the network data, a number of hosts in the network that exchanged data traffic with the second asset during a time period and generating a second security metric of the second asset based on the first security metric and the number of hosts. A security policy of the second asset is adjusted based on the security metric.

  • Patent number: 12244562
    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.
