Claim:
1. A security management system, comprising: a center server; and a plurality of relay servers receiving at least one datum of data stored in the center server and storing the received at least one datum, wherein each of the plurality of relay servers comprises a relay control unit and a relay database, and the center server comprises a center control unit and a center database, and the center server is configured to transmit requested information to a client via at least one of the plurality of relay servers, and wherein a first relay server of the plurality of relay servers stores access authentication information transmitted from the center database to the relay database, transmits data requested by the client to the client when access information received from the client matches with the access authentication information, and, when the access information received from the client does not match with the access authentication information, the first relay server determines an access from the client as a malicious access, blocks the access from the client, formats the relay database and transmits information related to the malicious access to the center server, and, when the center server receives information on the malicious access, the center server transmits a ‘block relay’ command instructing the first relay server to stop a relay function to the first relay server and a ‘start relay’ command instructing a second relay server of the plurality of relay servers to perform the relay function to the second relay server, and controls the second relay server so as to perform the relay function.
