    摘要： Systems and methods are provided for receiving, at a network device, a first set of rules from a security controller of an enterprise network, the first set of rules being different from a second set of rules provided to a firewall by the security controller, implementing, at the network device, the first set of rules received from the security controller, generating, at the network device, a first log including metadata based on the first set of rules, the first log being generated on a per flow basis, notifying, at the network device, a NetFlow of the first log including the metadata of the first set of rules, and providing, from the network device, the first log to a cloud-log store by the NetFlow of the network device, the cloud-log store receiving the first log from the network device and a second log from the firewall.

    摘要： A method comprises receiving, at a network infrastructure device, a flow of packets, determining, using the network infrastructure device and for a first subset of the packets, that the first subset corresponds to a first datagram and determining a first length of the first datagram, determining, using the network infrastructure device and for a second subset of the packets, that the second subset corresponds to a second datagram that was received after the first datagram, and determining a second length of the second datagram, determining, using the network infrastructure device, a duration value between a first arrival time of the first datagram and a second arrival time of the second datagram, sending, to a collector device that is separate from the network infrastructure device, the first length, the second length, and the duration value for analysis.
