Description

  The present invention relates to an information processing apparatus, a control method thereof, and a program, and more particularly to a technology for efficiently reducing erroneous transmission of electronic mail.

  In recent years, personal information and confidential information leaks have come to affect corporate trust. With the enforcement of various laws such as the Personal Information Protection Law, it is urgently necessary for companies to take measures against information leakage. Information leaks may occur due to unauthorized access from outside, but most of them are caused by the carelessness of people inside a company.

There is a mail filtering system as one of such information leakage measures. The e-mail filtering system sets e-mail characteristics as filtering conditions such as the presence or absence of a keyword having a high possibility of information leakage, and selects e-mails to be subjected to audit or transmission control. The administrator can prevent information leakage efficiently by visually judging the sorted e-mail.

As such prior art, Patent Document 1 selects e-mails to be audited based on preset conditions, and displays a list of e-mails selected for the administrator corresponding to the e-mail sender. And a mechanism for prompting audits is disclosed.

<Description of FIG. 3>
Next, the basic processing flow of the mail audit apparatus will be described with reference to FIG.

FIG. 3 is a flowchart showing the basic processing of the mail inspection device according to the embodiment of this invention.

In step S301, the e-mail reception processing unit 101 of the e-mail audit apparatus 100 receives (acquires) the e-mail transmitted by the e-mail transmitting / receiving terminal 120 (acquisition means).

The mail reception processing unit 101 passes the received electronic mail to the delivery control unit 102, and the delivery control unit 102 executes the processing after step 302.

The delivery control unit 102 reads out and obtains the delivery rule shown in 901 of FIG. 9 (S302).

In step S303, the delivery control unit 102 reads a table (also referred to as delivery rule table) of the delivery rule 901 stored in the delivery rule storage unit 104 (condition storage unit) into a memory such as a RAM.

An example of the delivery rule 901 is shown in 901 of FIG.

One row of the table represents one delivery rule. One delivery rule is a record composed of a rule ID, a conditional expression, and an action.

In the conditional expression in the table, the condition for specifying the e-mail is described. For example, the condition regarding the email address of the sender or the recipient, the presence or absence of an attached file, the document type of the attached file, or the number of destination addresses, whether a predetermined keyword is included in the email or a sender shown in 902 described later Whether point (value) (hereinafter also referred to as a point value) is larger than a predetermined value is used. Further, it is assumed that the size of the point value of the transmission source can be set as a condition as shown in the example of the conditional expression column of the row 901.

Here, for example, in the record with a rule ID of 2 in 901 in FIG. 9, it is defined that an e-mail with a point value of transmission source larger than 1 is suspended. Further, it is defined that the record (content condition) having a record ID of 1 is to delete the e-mail when the e-mail includes the keyword “internally confidential”. Also, for records with a record ID of 3, the sender is "*

e. co. In the case of "jp", it is defined that the e-mail is sent.

In step S303, the delivery rules are extracted one by one from the delivery rule table in ascending order of the rule ID, and it is determined whether the e-mail matches the conditional expression of the retrieved delivery rules. If the e-mail matches the condition, the process proceeds to step S304. If the e-mail does not meet the condition, next, the young delivery rules with the rule ID are extracted one by one, and it is determined whether the e-mail matches the conditional expression of the taken-out delivery rule. Even if it is determined whether or not the e-mail matches the conditions of all the delivery rules, if the e-mail does not match any upper limit, the process proceeds to step S305.

In step S305, the electronic mail is passed to the mail transmission processing unit 103, and the mail transmission processing unit 103 transmits the electronic mail to the mail delivery apparatus 140.

Next, in step S304, the value of the action string of the delivery rule determined to match is extracted, and if the value is transmission, the process proceeds to S305, if it is deletion, the process proceeds to step S306;

In step S305, the electronic mail is passed to the mail transmission processing unit 103, and the mail transmission processing unit 103 transmits the electronic mail to the mail delivery apparatus 140.

In step S306, the e-mail is deleted.

In step S307, sending of the e-mail is suspended and set as an e-mail to be audited.

The above is the flow of the basic processing in the mail audit device.
<Description of FIG. 4>
Next, the e-mail storage unit of the e-mail audit apparatus 100 transmits the e-mail (audited e-mail) whose transmission is suspended and stored, the administrator (user) who audits the e-mail, or the e-mail The process which the transmitted sender (user) audits will be described with reference to FIG.

FIG. 4 shows an email (audit target email) whose transmission is suspended and saved in the audit target email storage unit of the email audit apparatus 100, a manager (user) who audits the email, or the email. It is a flowchart which shows an example of the process which the transmitting sender (user) who transmitted transmitted audits.

The process illustrated in the flowchart illustrated in FIG. 4 is executed when transmission of the e-mail is suspended at S307.

Each process shown in the flowchart shown in FIG. 4 is realized by being executed by the CPU of the mail audit apparatus 100.

The audit operation processing unit 107 of the mail audit apparatus 100 executes each process shown in the flowchart shown in FIG.

The e-mail audit apparatus 100 acquires the e-mail whose transmission has been suspended in S307, and acquires the erroneous transmission history information of the transmission source of the e-mail from the erroneous transmission history table 902 (S401). S401 is an application example of the acquisition unit of the present invention, and acquires an email for which transmission has been suspended.

In the erroneous transmission history table 902 shown in 902 in FIG. 9, the number of transmissions of erroneous transmissions for the most recent predetermined period (for example, the last month) from the processing time is recorded for each content of erroneous transmission and for each transmission source There is.

Here, the erroneous transmission history information (also referred to as erroneous transmission history) indicates information of each record of the erroneous transmission history table 902 shown in 902 of FIG.

The false transmission history table 902 includes the sender (sender's e-mail address), attachment error / forgotten attachment (number), destination mistake (number), write email transmission (number), sender's erroneous transmission point value It consists of items.

The transmission source item stores the transmission source e-mail address.

In the item of attachment error / forgetting attachment (number of times), the number of times the transmission source has instructed to send a mail in the state of attachment error or attachment failure is stored.

The misplaced item field stores the number of times the sender has issued a mail transmission instruction with the misplaced address.

The number of times that the sender has issued a mail transmission instruction while the mail is being written is stored in the item of “post-write mail transmission”.

As shown at 902 in FIG. 9, takahashi @ a. co. It has been shown that the jp sender has not been erroneously sent at least once in the last month.

Also, tanaka @ a. co. As for the transmission source of jp, it is shown that the number of times of sending the e-mail in a state of being written is one, and the erroneous transmission point value is one.

Also, yoshida @ a. co. The sender of jp is attachment error / attachment failure (number of times) is 1 time, address error (number of times) is 1 time, the number of times the e-mail is sent in the state of overwriting is 1 time, erroneous transmission It is shown that the point value is 7 points.

Also, kimura @ a. co. In the transmission source of jp, it is shown that the address error (number of times) is one and the number of erroneous transmission point values is three.

Also, wada @ a. co. The sender of jp is attachment mistake / forgetting attachment (number of times) is 2 times, address mistake (number of times) is 2 times, and the number of times the e-mail has been sent in the state of overwriting is 1 time, erroneous transmission It is shown that the point value is 13 points.

An example application 902 of erroneous transmission history information according to the present invention is shown in FIG. 9, and for each transmission source, the type of erroneous transmission of an e-mail instructed to be sent from the transmission source, and the number of erroneous transmissions with that type. including. Also, the erroneous transmission history information is stored in storage means such as a memory.

The mail inspection apparatus 100 calculates the erroneous transmission point value of the transmission source from the erroneous transmission history information acquired in S401 and the information of the point weight value table 903 (S402).

903 shown in FIG. 9 is a diagram showing an example of a point weight value table.

In the point weight value table, point value weight values are stored for each content of erroneous transmission (attachment error / forgotten attachment, wrong address, transmission of overwriting mail).

Specifically, “3” for attachment error / forgetting attachment, “3” for destination error, and “1” for write email transmission are stored as point value weights.

In S402, for example, the erroneous transmission history information acquired in S401 is sent from the sender wada @ a. co. In the case of a jp record, “Attachment error / Forgetting attachment (number of times) (2 times) x 3 + Address mistake (number of times) (2 times) x 3 + Number of times e-mail was sent in a state of overwriting (once) x 1” By performing the calculation of, an erroneous transmission point value (13 points) can be obtained.

In this manner, the mail audit apparatus 100 erroneously transmits the transmission source based on the content of the erroneous transmission of the past e-mail from the transmission source of the e-mail whose transmission is suspended in S307 and the result (number of times) of erroneous transmission. A point value (point value) can be calculated.

The erroneous transmission point value (point value) of the transmission source is the numerical value of the risk that an incident of erroneous transmission of an e-mail has occurred in the past from the transmission source.

Then, the mail inspection apparatus 100 determines which conditional expression of the audit rule 904 (FIG. 9) corresponds to the point value calculated in S402.

Reference numeral 904 in FIG. 9 is a diagram illustrating an example of an audit rule.

The audit rule 904 includes items of a rule ID, a conditional expression, and an action.

For example, in the conditional expression of the record whose rule ID is 1, it is defined that the value of the point calculated in S402 is larger than 1 and if this condition is satisfied, the simplified audit method by the transmission source is used. Indicates that audit is to be performed as an action.

For example, in the conditional expression of the record whose rule ID is 2, it is defined that the point value calculated in S402 is larger than 2 and when this condition is satisfied, the detailed audit method by the transmission source is used. Indicates that audit is to be performed as an action.

For example, in the conditional expression of the record having a rule ID of 3, it is defined that the point value calculated in S402 is larger than 8 and when this condition is satisfied, the administrator audits the audit method It shows that we do as an action.

The mail audit apparatus 100 specifies (determines) an action corresponding to the condition among the conditions indicated by the conditional expressions of the audit rule 904 (FIG. 9), the point value calculated in S402 (S403).

Then, if the specified (judged) action is the simplified inspection method by the transmission source in S403, the mail inspection apparatus 100 shifts the processing to S404, and the action is the detailed audit by the transmission source. If it is a method, the process proceeds to S405, and if the action is an administrator audit method, the process proceeds to S406.

In step S404, the method of auditing the email currently being processed and held in step S307 is set as the simplified audit method by the sender.

In S405, the method of auditing the e-mail pending in S307, which is the current process target, is set as the method of detailed audit by the sender.

In step S406, the method of auditing the email currently being processed and held in step S307 is set as the method of auditing by the administrator.

That is, in S404 and S405, it is determined that the transmission source is to audit the e-mail currently held in S307, which is the processing target. Also, in S406, it is determined that the administrator is to audit the email currently being processed and held in S307.

S403 to S406 are application examples of the determination means of the present invention, and the acquisition according to the type of erroneous e-mail transmission from the transmission source of the e-mail acquired by the acquisition means of S401 or the number of erroneous transmissions Determine the request destination of the audit of the e-mail acquired by the means.

In addition, the determination unit may perform an audit of the email acquired by the acquisition unit according to the type of erroneous transmission of the past email from the transmission source of the email acquired by the acquisition unit of S401, or the number of erroneous transmissions. It is determined whether the request destination is an e-mail transmission source or an e-mail management terminal operated by a manager of the e-mail.

In addition, the determination unit is an acquisition unit according to the type of erroneous e-mail transmission from the transmission source of the e-mail acquired by the acquisition unit of S401, and the value calculated based on the number of erroneous transmissions for each type. Decide where to request audits of emails obtained by

Then, the mail inspection apparatus 100 identifies the erroneous transmission content (error transmission history content) erroneously transmitted by the transmission source, which is included in the erroneous transmission history (record) acquired in S401 (S407). Specifically, it specifies the erroneous transmission contents of attachment error / forgetting attachment, address error, and overwriting mail transmission having a value of 1 (time) or more.

The mail audit apparatus 100 checks the audit method set in any of S404, S405, and S406, and the erroneous transmission content (error transmission history content) specified in S407, in order to audit the e-mail suspended in S307. To generate an audit screen according to (S408).

Next, the audit screen generated in S408 will be described using FIGS.

For example, when it is set in S404 that the e-mail suspended in S307 is to be audited by the simplified audit method by the sender, the simplified audit screen 500 shown in FIG. 5 is generated.

FIG. 5 is a diagram showing an example of the simple audit screen 500. As shown in FIG.
