    摘要: A method and apparatus is disclosed herein for TCP SYN flood protection. In one embodiment, a TCP SYN flood protection arrangement comprises a first device operable to process packet input and output functions, including performing sender verification with respect to a connection initiation from a sender for a first TCP connection between the sender and a destination server and a second device, separate from the first device, to perform one or more security processing operations on packets of the first TCP connection from the sender after the first device verifies the sender is legitimate.

    摘要: A method and apparatus is disclosed herein for IP packet tunneling in a network. In one embodiment, the method comprises receiving, at a first network device, a first IP packet of a IP connection; creating a second IP packet by replacing information in a field in the first IP packet with a session ID identifying the IP connection; and forwarding, by the first network device, the second IP packet to the second network device in the distributed network environment.

    摘要: A network system includes a security device and a network access device. The network access device is to receive a packet from a source node destined to a destination node, and to examine a data structure maintained by the network access device to determine whether the data structure stores a data member having a predetermined value, the data member indicating whether the packet should undergo security processing. If the data member matches the predetermined value, the packet is transmitted to a security device associated with the network access device to allow the security device to perform content inspection, and in response to a response received from the security device, the packet is routed to the destination node dependent upon the response. The packet is routed to the destination node without forwarding the packet to the security device.

    摘要: A network system includes a first network access device having an input/output (IO) module of a firewall to capture a packet of a network session originated from a first node associated with the first network access device, a first security device having a firewall processing module to determine based on the captured packet whether the first node is a destination node that is receiving VM migration from a second node that is associated with a second network access device. The first security device is to update a first flow table within the first network access device. The network system further includes a second security device to receive a message from the first security device concerning the VM migration to update a second flow table of the second network access device, such that further network traffic of the network session is routed to the first node without interrupting the network session.

    摘要: A method and apparatus is disclosed herein for distributed zone-based security. In one embodiment, the method comprises: determining an ingress security zone associated with an ingress of a first network device based on a first key and a media access control (MAC) address of a source of a packet; determining an egress security zone of a second network device based on a MAC address of a destination for the packet and a second key; performing a policy lookup based on the ingress security zone and the egress security zone to identify a policy to apply to the packet; and applying the policy to the packet.
