Abstract

The present invention provides a method for judging and blocking a network point, comprising a packet receiving step and a packet judging processing step, the packet collecting step accepts the ARP packet of the network point in the network segment, and the packet judging processing step is based on a permission list and the network point's The IP address and media access control address in the ARP packet are used to judge whether the network is legal, so as to block the packet or allow the connection, thereby protecting the network system and improving the security of network use.

Description

technical field [0001] The invention relates to a method for judging and blocking a network point, in particular to a method for judging and blocking the legality of a network point according to an allow list. Background technique [0002] The widespread use of the Internet today has enhanced the ease of information exchange. However, exchanging information via the Internet also carries many risks. For example, the personal financial authentication data in e-commerce on the network is stolen, or the computer system is hacked, which further leads to data leakage, computer poisoning, damage to important files, and even computer system failure, which affects the personal or corporate security. rights and interests. [0003] Receiving network packets has its own risks, especially packets from a dangerous network point, such as packets sent by external computers through the network, which can endanger other people's computers in various ways, including wiretapping, tampering, a...
