    Abstract: A privatized link between an origin server and a content delivery network is provided. A privatized link can be a direct connection that does not route over the internet. Another privatized link is one that rotates IP addresses. An origin server may be assigned to use a set of multiple IP addresses for communication with the content delivery network. However, at any given time, the origin server is only using a small number of IP addresses. When one of the IP addresses being used to communicate with the content delivery network comes under attack, the origin server switches to another IP address in the set in order to continue serving content to the content delivery network via an IP address that is not under attack.

  • Patent number: 11616759
    Abstract: A cloud-based traffic classification engine maintains a catalog of application-based traffic classes which have been developed based on known applications, and a local traffic classification engine maintains a subset of these classes. Network traffic intercepted by the firewall which cannot be classified by the local engine is forwarded to the cloud-based engine for classification. Upon determination of a class of the traffic, the cloud-based engine forwards the determined class and corresponding signature to the local engine. The firewall maintains a cache which is updated with the signatures corresponding to the class communicated by the cloud-based engine. Subsequent network traffic sent from the application can be determined to correspond to the application and classified according locally at the firewall based on the cached signatures. Localization of the cache to the firewall reduces latency of traffic classification operations as the catalog of classification information stored in the cloud scales.

  • Patent number: 11606346
    Abstract: A logic circuit for managing reception of secure data packets in an industrial controller snoops data being transferred by a Media Access Controller (MAC) between a network port and a shared memory location within the industrial controller. The logic circuit is configured to perform authentication and/or decryption on the data packet as the data packet is being transferred between the port and the shared memory location. The logic circuit performs authentication as the data is being transferred and completes authentication shortly after the MAC has completed transferring the data to the shared memory. The logic circuit coordinates operation with the MAC and signals a Software Packet Processing (SPP) module when authentication is complete. The logic circuit is further configured to decrypt the data packet, if necessary, and to similarly coordinate operation with the MAC and delay signaling the SPP module that data is ready until decryption is complete.

The method further includes in response to determining that the packet comprises an IPV4 packet, identifying a first entry in an adjacency table. The first entry is associated with an address prefix. The address prefix is associated with first Internet Protocol (IP) address of the data packet. The first entry indicates a next hop for the data packet. The adjacency table comprises a second entry associated with the address prefix. The method further includes forwarding the packet to the next hop indicated by the first entry in the adjacency table, via an egress interface of the network device.

  • Patent number: 11539664
    Abstract: A packet-filtering network appliance such as a threat intelligence gateway (TIG) protects TCP/IP networks from Internet threats by enforcing certain policies on in-transit packets that are crossing network boundaries. The policies are composed of packet filtering rules derived from cyber threat intelligence (CTI). Logs of rule-matching packets and their associated flows are sent to cyberanalysis applications located at security operations centers (SOCs) and operated by cyberanalysts. Some cyber threats/attacks, or incidents, are composed of many different flows occurring at a very high rate, which generates a flood of logs that may overwhelm computer, storage, network, and cyberanalysis resources, thereby compromising cyber defenses.

  • Patent number: 11533340
    Abstract: Systems, methods, and computer-readable media for on-demand security provisioning using whitelist and blacklist rules. In some examples, a system in a network including a plurality of pods can configure security policies for a first endpoint group (EPG) in a first pod, the security policies including blacklist and whitelist rules defining traffic security enforcement rules for communications between the first EPG and a second EPG in a second pods in the network. The system can assign respective implicit priorities to the one or more security policies based on a respective specificity of each policy, wherein more specific policies are assigned higher priorities than less specific policies. The system can respond to a detected move of a virtual machine associated with the first EPG to a second pod in the network by dynamically provisioning security policies for the first EPG in the second pod and removing security policies from the first pod.

  • Patent number: 11526613
    Abstract: A computer system has a separation mechanism which enforces separation between at least two execution environments such that one execution environment is a gatekeeper which interposes on all communications of the other execution environment. The computer system has an attestation mechanism which enables the gatekeeper to attest to properties of the at least two execution environments. A first one of the execution environments runs application specific code which may contain security vulnerabilities. The gatekeeper is configured to enforce an input output policy on the first execution environment by interposing on all communication to and from the first execution environment by forwarding, modifying or dropping individual ones of the communications according to the policy. The gatekeeper provides evidence of attestation both for the application specific code and the policy.

  • Patent number: 11509695
    Abstract: Information associated with a controlled-environment facility resident communications and/or data device, such as device location within the controlled-environment facility, may be used to determine whether the resident device is approved for two-way video visitation or restricted to on-way video visitation. Video visitation may be initiated and voice and video captured and streamed by a non-resident communications and/or data device, as well as voice and/or video captured and streamed by the resident device, is received by a controlled-environment facility electronic communications management system. Voice and video captured at the non-resident device is transmitted to the resident device and, if the resident device is permitted two-way video visitation, voice and video captured by the resident device is transmitted to the non-resident device, if the resident device is restricted to one-way video visitation, only voice is transmitted to the non-resident device.

  • Patent number: 11496377
    Abstract: An approach for detecting anomalous flows in a network using header field entropy. This can be useful in detecting anomalous or malicious traffic that may attempt to “hide” or inject itself into legitimate flows. A malicious endpoint might attempt to send a control message in underutilized header fields or might try to inject illegitimate data into a legitimate flow. These illegitimate flows will likely demonstrate header field entropy that is higher than legitimate flows. Detecting anomalous flows using header field entropy can help detect malicious endpoints.
