One or more computing devices, systems, and/or methods for monitoring levels of activity of client devices using a cluster of servers having a decentralized network architecture are provided, where over-counting, which may be caused by an uneven distribution of requests transmitted by the client devices to the cluster of servers, may be mitigated. For example, a request may be received by a first server, of the cluster of servers, from a client device. A first counter value associated with a level of activity of the client device may be incremented by a first number. One or more data packets may be transmitted to one or more servers of the cluster of servers. Each data packet of the one or more data packets may comprise an instruction to increment a counter value associated with the client device by a second number, which may be different than the first number.

In one embodiment, an elimination point device in a network obtains a master secret from a network controller. The elimination point device assesses, using the master secret, whether an incoming packet received by the elimination point device from a redundant path between the elimination point device and a replication point device in the network includes a valid message integrity check (MIC). The elimination point device determines whether the incoming packet was injected maliciously into the redundant path, based on the assessment of the incoming packet. The elimination point device initiates performance of a mitigation action in the network, when the elimination point device determines that the incoming packet was injected maliciously into the redundant path.

A connection control apparatus is configured such that a connection count calculator calculates a TCP connection count, which is the number of TCP connections established between a server and one or more clients on a network, of each of servers on the network. The connection control apparatus is configured such that, when a determiner determines that the calculated count is larger than or equal to a predetermined threshold value, an anomalous connection detector detects anomalous connection, and a packet controller controls packet transmission and reception over the anomalous connection.

A management entity obtains from a first wireless access point a Basic Service Set (BSS) color collision event detected by the first wireless access point. The first wireless access point uses a first BSS color. A color collision event occurs when the first wireless access point receives from a device in a BSS of a different physical wireless access point a frame or PHY Protocol Data Unit (PPDU) that includes the first BSS color. The management entity obtains from the first wireless access point an indication whether the color collision event has been detected for longer than a predetermined duration. When the color collision event has been detected for longer than the predetermined duration, the management computes a probability of the color collision event. The management entity determines whether the color collision event is malicious or benign, and determines whether to maintain the first BSS color.

Implementations of the present disclosure involve a system and/or method for identifying and mitigating malicious network threats. Network data associated is retrieved from various sources across a network and analyzed to identify a malicious network threat. When a threat is found, the system performs a mitigating action to neutralize the malicious network threat.

A method and a system of restricting data packet transmission of an apparatus at a network node. The network node, during a first time period, updates a whitelist and does not restrict data packet transmission according to the whitelist. After the first time period, the network node determines corresponding destination address of each of the data packets and allows the data packets to be sent to the corresponding destination address if a criteria is satisfactory. The network node does not allow the data packets to be sent to the corresponding destination address if the criteria is not satisfactory. The whitelist is comprised of at least one destination address. The criteria is based on the at least one destination address. The whitelist list is stored in non-transitory computer readable storage medium in the network node.

In one embodiment, a centralized controller maintains a plurality of hierarchical behavioral modules of a behavioral model, and distributes initial behavioral modules to data plane entities to cause them to apply the initial behavioral modules to data plane traffic. The centralized controller may then receive data from a particular data plane entity based on its having applied the initial behavioral modules to its data plane traffic. The centralized controller then distributes subsequent behavioral modules to the particular data plane entity to cause it to apply the subsequent behavioral modules to the data plane traffic, the subsequent behavioral modules selected based on the previously received data from the particular data plane entity. The centralized controller may then iteratively receive data from the particular data plane entity and distribute subsequently selected behavioral modules until an attack determination is made on the data plane traffic of the particular data plane entity.

A method includes a network device that obtains Border Gateway Protocol (BGP) route information, where the B GP route information includes a target route prefix; obtains, based on the target route prefix, a region identifier of a region to which the target route prefix actually belongs; and verifies the BGP route information based on the target route prefix and the region identifier of the region to which the target route prefix actually belongs.
