METHOD AND APPARATUS FOR CONTROLLING BLOCKING OF SERVICE ATTACK BY USING ACCESS CONTROL LIST

摘要

An attack blocking control method using an access control list (ACL) of the present invention comprises the steps of: if a packet is input, checking whether or not the packet is a registered packet by searching the ACL; comparing a current time count value with a blocking time of the packet if the packet is the registered packet; increasing the number of blocking times of the packet by one if the current time count value is less than or equal to the blocking time and automatically renewing the blocking time; and deleting registration information on the packet from the ACL if the current time count value is greater than or equal to the blocking time.
