Document Type and Number:
Japanese Patent JP6840690
Kind Code:
B2
Abstract:
A DDoS handling device configured to handle communication directed to a target of a DDoS attack flowing in from an adjacent autonomous system in an autonomous system provided with a plurality of mitigating locations includes: a load distribution determination unit configured to determine whether or not to execute load distribution processing on the basis of an amount of available resources at mitigating locations corresponding to a gateway device into which the communication directed to the target flows and an amount of the communication directed to the target in a case in which at least one attack has been detected; a load distribution processing unit configured to decide mitigating locations to be used to handle the communication directed to the target from among the plurality of mitigating locations to solve shortage of resources at the mitigating locations for each attack, in a case in which the load distribution determination unit determines to execute the load distribution processing; and an attack handling setting unit configured to execute path control such that the communication directed to the target pertaining to the attack passes through the mitigating locations decided by the load distribution processing unit for each attack.
