Abstract

An apparatus, system, and method are disclosed to failover to a standby server when a primary server is under broadcast storm or denial-of-service (“DoS”) attack. A primary attack sensing module is included to monitor a rate of incoming data from a computer network to a primary server and to determine if the rate of incoming data is above a primary data rate threshold. A standby contact module is included to request a standby data rate status from a standby server in response to the primary attack module determining that the rate of incoming data to the primary server is above the primary data rate threshold. The standby server is connected to the primary server over a private network. The standby data rate status includes a determination by the standby server of whether a rate of data received by the standby server is above a standby data rate threshold. A standby receiver module is included to receive a standby data rate status from the standby server over the private network. A switchover module is included to deactivate the primary server and to send a command to activate the standby server as a primary server in response to the received standby data rate status indicating that the rate of data received by the standby server has not exceeded the standby data rate threshold.
