The present invention relates to a method for blocking a search for adult content wherein the client terminal performs mirroring of DNS query packets in an adult content blocking server of the network security system, and if a domain address of the DNS query packet is the domain address of a search server, a search for adult content is blocked by making corresponding adult content access a blocked search server. |
