Abstract

A network management system transmits/receives an email via a network; saves, in a database, first history information including the address of at least one of the destination and the source of the email written in the email; receives transmission information in which access information for accessing a web page via a network is written; saves, in the database, second history information including the access information written in the transmission information; inputs authentication information for identifying a user; and selectively displays the first history information saved in the first saving unit and the second history information saved in the second saving unit in a predetermined display format on a display unit by switching between the first history information and the second history information based on an instruction inputted by a user when the inputted authentication information is identical to previously registered information.

Claims

1. A network management system comprising:

a first saving unit adapted to save, in a database, first history information including the address of at least one of the destination and the source of the email written in the email;

a receiving unit adapted to receive transmission information in which access information for accessing a web page via a network is written;

a second saving unit adapted to save, in the database, second history information including the access information written in the transmission information;

an input unit adapted to input authentication information for identifying a user; and

a display control unit adapted to selectively display the first history information saved in the first saving unit and the second history information saved in the second saving unit in a predetermined display format on a display unit by switching between the first history information and the second history information based on an instruction inputted by a user when the inputted authentication information is identical to previously registered information.

2. The network management system according to claim 1, wherein the display control unit displays the first history information and the second history information in time-series on the display unit.

3. The network management system according to claim 2, wherein the display control unit changes the display order of the first history information and the second history information in response to an instruction inputted by a user.

4. The network management system according to claim 1, wherein the database saves the first history information and the second history information in CSV format.

5. The network management system according to claim 1, wherein the first history information includes the address of at least one of the destination and the source of an unsolicited email written in the unsolicited email.

6. A network management system comprising:

a receiving unit adapted to receive an email sent via a network;

a saving unit adapted to save, in a database, history information including access information for accessing a web page that is written in body of the email or in a document file attached to the email;

an input unit adapted to input authentication information for identifying a user; and

a display control unit adapted to display the saved history information on a display unit when the inputted authentication information is identical to previously registered information.

7. A network management system comprising:

a receiving unit adapted to receive an email sent via a network;

a first determining unit adapted to determine whether or not the received email is an unsolicited email;

an extracting unit adapted to extract access information for accessing a web page and/or email address information that are written in body of the email or in a document file attached to the email when the first determining unit determines the email to be an unsolicited email; and

a saving unit adapted to save, in a database, the access information and/or the address information extracted by the extracting unit.

8. The network management system according to claim 7, further comprising;

a transmitting unit adapted to transmit an email via a network;

a second determining unit adapted to determine whether or not a destination address is identical to address information saved by the saving unit when transmitting the email; and

a control unit adapted to either block transmission of the email, issue a warning, or execute both when the second determining unit determines the destination address is identical to the saved address information.

9. The network management system according to claim 7, wherein the database further stores filter information for determining an unsolicited email, and

the first determining unit determines whether or not the email is an unsolicited email based on the filter information.

10. The network management system according to claim 9, wherein the database further stores access information to a malicious web page, and

the first determining unit determines the received email to be an unsolicited email when the email contains the access information stored in the database.

11. The network management system according to claim 9, further comprising:

a filter information receiving unit adapted to receive filter information from an external data center apparatus; and

an updating unit adapted to update the filter information stored in the database based on the filter information received by the filter information receiving unit.

12. The network management system according to claim 11, further comprising:

a filter information transmitting unit adapted to transmit the filter information stored in the database to the data center apparatus.

13. The network management system according to claim 8, further comprising:

a third determining unit adapted to determine whether or not access information contained in request information that requests access to a server apparatus located on an external network is identical to the access information saved by the saving unit when transmitting the request information,

wherein the control unit either blocks transmission of the request information, issues a warning, or executes both when the third determining unit determines the access information to be identical to the saved access information.

14. The network management system according to claim 8, further comprising:

a fourth determining unit adapted to determine, when transmitting transmission information including email address information by the POST method, whether or not the email address information is identical to the address information saved by the saving unit,

wherein the control unit either blocks transmission of the transmission information, issues a warning, or executes both.

15. A network management method in a network management system comprising:

a transmitting/receiving step of transmitting/receiving an email via a network;

a first saving step of saving, in a database, first history information including the address of at least one of the destination and the source of the email written in the email;

a receiving step of receiving transmission information in which access information for accessing a web page via a network is written;

a second saving step of saving, in the database, second history information including the access information written in the transmission information;

an input step of inputting authentication information for identifying a user; and

a display control step of selectively displaying the first history information saved in the first saving step and the second history information saved in the second saving step in a predetermined display format on a display unit by switching between the first history information and the second history information based on an instruction inputted by a user when the inputted authentication information is identical to previously registered information.

16. A network management method in a network management system comprising:

a receiving step of receiving an email sent via a network;

a saving step of saving, in a database, history information including access information for accessing a web page that is written in body of the email or in a document file attached to the email;
