Description

Technical Field

[0001] The present invention relates to the technical field of email subject frequency control, and in particular to a method for frequency control of the same email subject during holidays. Background Art

[0002] Frequency control of emails with the same subject is mainly based on systematic inspection and analysis of sent emails, identifying and processing emails with the same subject, preventing users from sending large quantities of phishing emails after being stolen, and external phishing attacks. In the current email system, facing a large number of emails with the same subject, the existing email prevention and control system mainly relies on fixed frequency control rules and cannot distinguish between weekdays and holidays. If there is no one on duty during holidays, the company will face high-risk phishing attacks. During holidays, once an internal account is stolen, various phishing emails will be sent out. Since the conventional frequency control of emails with the same subject is global, the limit value is large and cannot be triggered in time. At the same time, external attackers may choose to launch phishing attacks on holidays, which may cause phishing emails to break through the defense line. Since the traditional frequency control rules for emails with the same subject fail to make special treatment for holidays, these malicious behaviors are often unable to be discovered and prevented in time. In order to solve the above problems, a method for frequency control of emails with the same subject during holidays is proposed. Summary of the invention

[0003] In view of the above technical problems, the present invention provides a method for frequency control of the same email subject during holidays, characterized in that it includes the following steps:

[0004] The content detection module performs content detection on received emails;

[0005] Determine whether the received email is spam;

[0006] If yes, intercept and process the email, save the email subject and current time point, and end the whole process;

[0007] If not, determine whether the email meets the frequency control exemption condition;

[0008] If yes, it will be delivered directly, ending the whole process;

[0009] If not, save the email subject and current time point;

[0010] Confirm whether the current holiday status is a statutory holiday;

[0011] If yes, the frequency control threshold is set to the frequency control threshold of statutory holidays, and the number of occurrences of the topic within the specified time is calculated;

[0012] If it is greater than or equal to the threshold, the email is intercepted;

[0013] If it is less than the threshold, the mail is delivered;

[0014] Confirm whether the current holiday status is a statutory holiday. If not, determine whether the current holiday status is a personalized holiday.

[0015] If yes, the frequency control threshold is set to the frequency control threshold of the personalized holiday, and the number of occurrences of the topic within the specified time is calculated;

[0016] If not, the frequency control threshold is set to the conventional frequency control threshold, and the number of occurrences of the topic within the specified time is calculated;

[0017] The method of determining whether a received email is spam is to classify the email by analyzing the email subject and content, sender and recipient information, attachments, email headers, user feedback and history records, and then make a judgment through a machine learning algorithm;

[0018] Confirm whether the current holiday status is a statutory holiday. The method for determining statutory holidays is to use the web network to connect to the holiday public page through the holiday connection port to obtain the status of statutory holidays and determine whether the current holiday status is a personalized holiday. The personalized holiday is based on local configuration to obtain personalized holiday information;

[0019] Frequency control exemption conditions refer to whether the information of the email sender, recipient, and IP address meets the conditions for frequency control exemption;

[0020] The frequency control threshold refers to the frequency control threshold, including but not limited to the frequency control threshold of all topics, normal topics, and spam topics.

[0021] Beneficial effects of the present invention:

[0022] The present invention introduces a dynamic threshold adjustment mechanism for holidays. Traditional email frequency control systems usually adopt fixed threshold rules and cannot be adjusted according to specific holidays. The present invention allows users to customize email prevention and control strategies according to different holiday types through a built-in holiday identification module. This flexible prevention and control strategy setting function can adapt to the security needs of different holidays, making the system's prevention and control measures more in line with actual conditions to achieve higher prevention and control sensitivity. This innovation can timely detect and prevent the spread of a large number of phishing emails and malicious emails in response to special needs during holidays. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] If it is greater than or equal to the threshold, the email is intercepted;

[0040] If it is less than the threshold, the mail is delivered;

[0041] Confirm whether the current holiday status is a statutory holiday. If not, determine whether the current holiday status is a personalized holiday.

[0042] If yes, the frequency control threshold is set to the frequency control threshold of the personalized holiday, and the number of occurrences of the topic within the specified time is calculated;

[0043] If not, the frequency control threshold is set to the conventional frequency control threshold, and the number of occurrences of the topic within the specified time is calculated;

[0044] The method of determining whether a received email is spam is to classify the email by analyzing the email subject and content, sender and recipient information, attachments, email headers, user feedback and history records, and then make a judgment through a machine learning algorithm;

[0045] Confirm whether the current holiday status is a statutory holiday. The method for determining statutory holidays is to use the web network to connect to the holiday public page through the holiday connection port to obtain the status of statutory holidays and determine whether the current holiday status is a personalized holiday. The personalized holiday is based on local configuration to obtain personalized holiday information;

[0046] Frequency control exemption conditions refer to whether the information of the email sender, recipient, and IP address meets the conditions for frequency control exemption;

[0047] The frequency control threshold refers to the frequency control threshold, including but not limited to the frequency control threshold of all topics, normal topics, and spam topics.

[0048] Example 2

[0049] Step 100: The content detection module performs content detection on the received email;

[0050] Step 101: If it is detected as spam, intercept it, save the subject of the email and the current time point, and end the whole process;

[0051] Step 102: Check whether the mail meets the frequency control-free condition. If so, it is directly delivered and the whole process ends; otherwise, proceed to the next step;

[0052] Step 103: Save the email subject and current time point;

[0053] Step 104: Confirm the current holiday status. In this step, the system can obtain personalized holiday information based on local configuration, and can also synchronize the latest statutory holiday information database online to obtain the latest holiday status;

[0054] Step 105: If the current day is a statutory holiday, the frequency control threshold is set to the frequency control threshold of the statutory holiday, and the process proceeds to step 108;

[0055] The frequency control threshold here refers to the frequency control threshold, including but not limited to the frequency control threshold of all topics, normal topics, spam topics, etc.

[0056] Step 106: If the current holiday is a personalized holiday, such as a company-specific holiday, the frequency control threshold is set to the frequency control threshold of the personalized holiday, and the process proceeds to step 108;

[0057] Step 107: setting the frequency control threshold to a conventional frequency control threshold;

[0058] Step 108: Calculate the number of times the subject appears within the specified time. If it is greater than the threshold, intercept the email and end the entire process.

[0059] Step 109: Deliver the mail.

[0060] Example 3

[0061] The system has a built-in holiday detection module, which can identify whether the current date is a holiday by comparing it with the national statutory holidays and the company's internal holiday arrangement database;

[0062] Users can set different frequency control thresholds for different types of holidays (such as national statutory holidays, company internal holidays, etc.), and can also set different frequency control thresholds for emails per hour or every 24 hours during regular holidays;

[0063] During holidays, the system can dynamically adjust prevention and control strategies, and can conduct more effective prevention and control to prevent phishing, virus, malicious and other emails with the same subject from being sent in batches after internal accounts are stolen. At the same time, it can prevent external attacks from sending large numbers of phishing emails. By setting different holiday prevention and control thresholds in different scenarios, the system's prevention and control capabilities and accuracy can be improved, reducing the risk of malicious emails.

[0064] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.
