Phishing Mail Attack Prevention Methods Based on Reverse Proxy

Mail is one of the main channels for Internet users to communicate today. The spread and dissemination of some spam and even phishing emails has an imminent impact on Internet security and can even have a certain impact on the real industry. Therefore, it is urgent to prevent phishing emails. This paper proposes to use reverse proxy technology to establish a prevention system that can identify and screen many spam mails including phishing mails, so as to purify the network environment to a certain extent. In the comparative experiment on TPR (True Positive Rate, also known as sensitivity or recall rate), taking the number of 100 emails as an example, the TPR of the experimental group based on the method in this paper was $96.89 \%$, while that of the conventional network security system as the control group was $\mathbf{9 1 . 9 2 \%}$. It can be seen that the performance difference between the two is obvious, which reflects the effectiveness of the method in this paper.
