5. The method of claim 1 , wherein the basic information registration operation is performed by: a method of inputting, into the security system server directly by a security manager, the information about the user and the information about the mobile terminal apparatus; or a method of installing, by the mobile terminal apparatus, a security app (a mobile terminal security program), when the security system server transmits a uniform resource locator (URL) or an authentication code to the mobile terminal apparatus, using a short message service (SMS) or a quick response (QR) code, wherein the information about the user comprises a name of the user, and the information about the mobile terminal apparatus comprises a mobile phone number, and a media access control (MAC) address.

6. The method of claim 1 , wherein the privacy policy agreement operation is performed by: a method of registering the agreement in written form by a security manager transmitting the agreement to the security system server using an SMS; or a method of inputting, by the mobile terminal apparatus, whether the user agrees to a privacy policy, when the security system server transmits an URL or an authentication code to the mobile terminal apparatus using an SMS.

7. The method of claim 1 , wherein the blocking application operation is performed by: a method of providing security corresponding to site blocking, upload restrictions, and Internet blocking by interworking with a subscriber authentication system of a mobile communication provider, when a MAC address, information about a base station, or an identification number of the mobile terminal apparatus for each Internet protocol (IP) address received by the blocking server in real time corresponds to the registered information about the user.

8. The method of claim 1 , wherein the blocking application operation comprises identifying, by the blocking server, a target for blocking application, through an IP to be used and an identification number of a mobile terminal apparatus of the target.

9. The method of claim 1 , wherein the blocking application operation comprises identifying, by the blocking server, a target for blocking application, through an IP to be used and a MAC address of a mobile terminal apparatus of the target.

10. The method of claim 1 , wherein the blocking application operation comprises identifying, by the blocking server, a target for blocking application, through an app (a security program) installed in a mobile terminal apparatus of the target.

11. The method of claim 1 , wherein the blocking discontinuation operation is performed by: a method of discontinuing blocking by transmitting, by a security manager, a QR code to the security system server or inputting blocking discontinuation information into the security system server, when the mobile terminal apparatus leaves an area (inside of a workplace) to which the blocking policy applies; or a method of transmitting, to the security system server by the mobile terminal apparatus, information regarding whether blocking is discontinued, and uninstalling a security app and discontinuing blocking, simultaneously, when the mobile terminal apparatus leaves the area to which the blocking policy applies or when the security manager inputs uninstallation information for a case in which the security app is installed.

12. A method of securing a mobile terminal apparatus in a limited area requiring security, the method comprising: inputting information about a user and information about the mobile terminal apparatus into a security system server; notifying the security system server of information regarding whether an agreement on collection of traffic related to security and Internet blocking is obtained in advance; transmitting, by the security system server, a blocking policy to a blocking server; allowing or blocking, by the blocking server, an access of the mobile terminal apparatus to the Internet while the mobile terminal apparatus is in the limited area; in response to the mobile terminal apparatus leaving the limited area, discontinuing, by the security system server, the blocking of the mobile terminal apparatus by (A) transmitting, by a security manager, a QR code to the security system server when the mobile terminal apparatus leaves an area to which the blocking policy applies, (B) inputting blocking discontinuation information into the security system server when the mobile terminal apparatus leaves the area to which the blocking policy applies, or (C) transmitting, to the security system server by the mobile terminal apparatus, information regarding whether blocking is discontinued and uninstalling a security app in addition to discontinuing blocking, simultaneously, when the mobile terminal apparatus leaves the area to which the blocking policy applies or when the security manager inputs uninstallation information for a case in which the security app is installed; and in response to the mobile terminal apparatus leaving the limited area, notifying, by the security system server, the mobile terminal apparatus of discontinuation of the blocking policy.

13. The method of claim 12 , further comprising: transmitting, to the blocking server, a packet input into packet mirroring or packet filtering equipment installed between a base station and the blocking server, when the mobile terminal apparatus accesses the Internet through the base station.

14. The method of claim 12 , further comprising: tunneling, to the blocking server, a packet used by the mobile terminal apparatus, through software installed in the mobile terminal apparatus to support tunneling, when the mobile terminal apparatus accesses the Internet through a base station.

15. The method of claim 12 , further comprising: inputting the information about the user and the information about the mobile terminal apparatus into the security system server by (A) inputting, into the security system server directly by the security manager, a name of the user, a mobile phone number of the mobile terminal apparatus, and a media access control (MAC) address of the mobile terminal apparatus or (B) installing, by the mobile terminal apparatus, a mobile terminal security program, when the security system server transmits a uniform resource locator (URL) or an authentication code to the mobile terminal apparatus, using a short message service (SMS) or a quick response (QR) code.

16. The method of claim 12 , further comprising: notifying the security system server of information regarding whether the agreement is obtained by (A) registering the agreement in written form by the security manager transmitting the agreement to the security system server using SMS or (B) inputting, by the mobile terminal apparatus, whether the user agrees to a privacy policy, when the security system server transmits a URL or an authentication code to the mobile terminal apparatus using SMS.

17. The method of claim 12 , further comprising: allowing or blocking the access of the mobile terminal apparatus to the Internet by (A) providing security corresponding to site blocking, upload restrictions, and Internet blocking by interworking with a subscriber authentication system of a mobile communication provider, when a MAC address, information about a base station, or an identification number of the mobile terminal apparatus for each Internet protocol (IP) address received by the blocking server in real time corresponds to the registered information about the user and (B) discontinuing the security when the user agrees to collection of an Internet usage history.

18. The method of claim 12 , further comprising: allowing or blocking the access of the mobile terminal apparatus to the Internet by identifying, by the blocking server, a target for blocking application, through an IP to be used and an identification number of a mobile terminal apparatus of the target.

19. The method of claim 12 , further comprising: allowing or blocking the access of the mobile terminal apparatus to the Internet by identifying, by the blocking server, a target for blocking application, through an IP to be used and a MAC address of a mobile terminal apparatus of the target.

20. The method of claim 12 , further comprising: allowing or blocking the access of the mobile terminal apparatus to the Internet by identifying, by the blocking server, a target for blocking application, through a security program installed in a mobile terminal apparatus of the target.
