  • Method and apparatus for preventing DOS attacks on trunk interfaces
    Patent number: 9185129
    Abstract: A method of protecting a data network from denial of service (DOS) attacks is described. The method may use various network tools to selectively block or disable portions of a data trunk experiencing a DOS attack, thereby preventing the DOS attack from reaching at least some resources on the network. In one embodiment, a network switch identifies a virtual LAN (VLAN) carrying suspect data on a data trunk. The network switch then adjusts a spanning tree for the network so that one or more ports on the compromised VLAN are blocked or disabled, while non-compromised VLANs are allowed to continue carrying data. Other approaches are also presented for avoiding the loss of valid data when a network blocks one or more VLANs or other portions of a network in response to a DOS attack or other intrusion.
