Abstract: Examples of the present disclosure describe systems and methods for restricting the routing scope of an anycast service. In aspects, network traffic and/or network performance data may be received by a network device and/or an endpoint device in an anycast environment. The received network traffic and/or network performance may be evaluated using one or more automated logic systems or algorithms to identify indicators of potential failure or performance degradation for one or more devices in the anycast environment. Upon identifying one or more such indicators, a routing table of one or more network devices in the anycast environment may be dynamically modified to restrict routes to particular endpoint destinations. The network devices in the anycast environment may subsequently route network traffic according to the modified routing table(s).

Abstract: The present application describes a system and method for utilizing a tunnel in a networking routing protocol to provide a network segment access to additional servers when certain load balancing trigger events are detected.

Abstract: Examples of the present disclosure describe systems and methods for providing security against IP spoofing. In aspects, network traffic associated with one or more data requests may be received by a device in a computing environment. The network traffic may be evaluated using one or more automated logic systems or algorithms to identify suspicious or malicious behavior. The automated logic systems or algorithms may implement one or more analyses, such as asymmetric routing analysis, hardware device analysis, user and/or network behavior analysis, etc. Upon identifying suspicious or malicious behavior, the automated logic systems or algorithms may apply a filter to one or more computing devices. For example, a filter for blocking network traffic associated with the suspicious or malicious behavior may be applied to a computing device that is in close geographic and/or logical proximity to an attacking computing device.

Abstract: The present application describes a system and method for passively collecting DNS traffic data as that data is passed between a recursive DNS resolver and an authoritative DNS server. The information contained in the collected DNS traffic data is used to generate a virtual authoritative DNS server, or a zone associated with the authoritative DNS server, when it is determined that the authoritative DNS server has been compromised.

Abstract: A system for numeric pattern normalization for cryptographic signatures is provided. The system includes a resolving client, and an at least one signature server. The at least one signature server includes at least one processor and non-transitory computer readable media having encoded thereon computer software comprising a set of instructions executable by the at least one processor. The set of instructions may be executed by the signature server to generate a message to be transmitted to a resolving client, normalize the message via numeric pattern normalization, generate a hash value for the normalized message, and generate a cryptographic signature based on the hash value. The signature server may then generate a signed message having the message signed with the cryptographic signature, and transmit the signed message to the resolving client.
