Abstract

The invention provides a communication security protection system based on a local area network, which comprises a wireless router and a computer, the wireless router is externally connected with a network connector, the wireless router is connected with the computer through a network cable, the network cable is connected with a security protection device, the security protection device comprises a shell, one end of the shell is provided with a first mesh. The first mesh is connected with a first feeler lever through a network cable, a second mesh is formed in the other end of the shell and connected with a second feeler lever through a network cable, a gap is formed between the tail end of the first feeler lever and the tail end of the second feeler lever, and a contact mechanism is arranged on the upper portion of the shell and located above the gap. When the contact mechanism is triggered, the first feeler lever and the second feeler lever are connected through the contact mechanism, and when the contact mechanism is released, the first feeler lever and the second feeler lever are disconnected; and the network can be quickly disconnected by releasing the contact mechanism, so that further leakage of data information is effectively avoided, and the security of the network is greatly improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a communication security protection system based on a local area network. Background technique [0002] At present, there are often viruses in the local area network that use the principle of ARP spoofing to eavesdrop on data and copy themselves. Because these viruses use the ARP message format to randomly send out the MAC-IP address binding relationship and modify the ARP table of other hosts or gateways in the network, this makes other machines unable to access the Internet or communicate normally, which interferes with the normal operation of the entire LAN. run. [0003] In the prior art, the common method to solve the above problems is: set static ARP on all machines in the LAN on the egress router, manually set the MAC-IP binding relationship, and configure static ARP on each PC, set the router IP The MAC address corresponding to the address, although this method can pl...
