1. A system-on (SoC) and application-specific integrated circuit (ASIC)-based apparatus for detecting malicious code in a portable terminal, comprising an SoC,wherein the SoC includes:

  • a hardware-based firewall configured to perform a packet-filtering operation on a packet received from the outside through a media access control (MAC) unit according to a setting of a firewall setting unit in an SoC memory, and then store the filtered packet in an application memory or transfer the filtered packet to an anti-malware engine;

    the hardware-based anti-malware engine configured to detect malicious code by performing a pattern-matching operation between a code pattern in a file transferred from the firewall or a file received through an input/output (I/O) interface unit and a pattern of malicious code registered in a malware signature database (DB) of a mobile device application unit;

    the SoC memory configured to provide the setting of the firewall and support a file-decoding function for file format recognition of the anti-malware engine; and

    a hardware-based controller configured to control a switching operation to transfer the file filtered by the firewall directly to the application memory or to the anti-malware engine, and control a malicious code detection cycle of the anti-malware engine.
