Measure the test taker's knowledge about the dangers of ARP viruses and how to clear ARP viruses.

I. ARP virus analysisAPR virus is an address spoofing virus. When a host in the LAN runs the ARP spoofing Trojan program, it deceives all hosts and routers in the LAN so that all Internet traffic must pass through the virus host. Other users directly access the Internet through the vro and now access the Internet through the virus host. When switching, the user will be disconnected once. After you switch to

[ARP] ARP protocol and ARP attack

What is the ARP protocol. The ARP is short to address resolution PROTOCOL. Let's take a look at this scene: What do we do when we want to send a packet to the destination IP address in the network? First, we're going to get the address of the destination host, so what does this address mean? We look at the bottom, Ethernet network send information on the physical level is the current, network card can be ba

arp-Address Resolution Protocol (in-depth understanding of ARP protocol in practice)

A host that communicates in the same network (which is not specifically referred to as an Ethernet network) must have the MAC address of the target host to correctly send the data to the target host, so how to know the MAC address of the target host. Can be passed through the ARP protocol. The ARP protocol is used to obtain the corresponding MAC address of the destination IP address, that is, the

ARP principles and defects (with source code of ARP spoofing)

0 Introduction An important reason why the IP protocol is widely used globally is that it can run on almost all links, such as point-to-point serial lines, ring network FDDI, of course, the most common link layer supporting IP protocols is Ethernet. For point-to-point serial lines, there are only two nodes and there is no need to define physical addresses. For broadcast networks like Ethernet, each node on the network has a unique physical address. The datagram generated by the IP layer must pas

Security: Understand ARP attack principles to prevent ARP attacks

Have you ever experienced a sudden disconnection when you access the Internet on a LAN? After a while, it will return to normal again. Or the client status becomes red frequently, the user is disconnected frequently, the IE browser is prone to errors, and some common software is faulty. Or, if your LAN is connected through identity authentication, it will suddenly become authenticated but not accessible (you cannot ping the gateway ). If the above problem occurs, you should be careful, because y
