摘要

PURPOSE: A malicious code blocking device, a system thereof and a method thereof are provided to block a malicious code from each terminal within a network effectively.;CONSTITUTION: A malicious code blocking device comprises the first malicious code detection unit(211), the second malicious code detection unit(212), a pattern extracting unit(213), and a transceiver(214). The first malicious code detection unit detects whether a malicious code is included in a received e-mail based on stored malicious code patterns. The second malicious code detection unit detects the secondary malicious code when the malicious code is not included in the received e-mail. The pattern extracting unit extracts the new malicious code pattern from the malicious code detected in the second malicious code detection unit.;COPYRIGHT KIPO 2010
