ARP attack: the culprit that causes transient disconnection and large-scale network disconnection. In a LAN, IP addresses (Layer 3) and Layer 2 Physical addresses (MAC addresses) are converted through ARP. Some devices in Internet cafes, such as routers and computers with TCP/IP protocols, provide ARP cache tables to speed up communication. Currently, many attack

In the article "Principles and harms of ARP spoofing in Internet cafes", I introduced the principles and harms of ARP spoofing. I believe that all network administrators hate ARP spoofing, we hope that this phenomenon will be completely prohibited. Although I am not an internet cafe administrator, I am also responsible for 200 computers in five data centers. The

ARP virus is not the name of a virus, but the use of ARP protocol to spread the vulnerability of a class of viruses. If you are using a computer, you often encounter network disconnection or inability to use the situation, it is likely that the ARP virus. Under the WIN10 system, how to Avira ARP virus? The following sm

? 1.1 What is a gatewayFirst of all, to explain what a gateway is, the gateway works in the OSI seven layer model of the transport layer or application layer, for the connection between the different networks of the high-level protocol, simply speaking, the gateway is like a room to another room door.　　What is the 1.2 arp protocol?ARP (address Resolution Protocol) addresses translation protocol, which works

ARP: Address Resolution Protocol When a host sends an Ethernet data frame to another host located on the same LAN, the destination interface is determined based on the 48-bit ethernet address. Device DriverProgramNever check the destination IP address in the IP datagram. The IP address resolved to a 32-bit IP address and any type of IP address used by the data link layer provides dynamic ing. RFC 826 is the description of

An ARP table is a dynamic table stored in a computer. It is used to correspond an IP address to a MAC address.Assume that computer A communicates with computer B in the same subnet segment.Computer A's IP address 192.168.0.1 MAC address AA-AA-AA-AA-AA-AAIP address of computer B known 192.168.0.2 MAC Address UnknownThen computer A will initiate an ARP query. "Who can tell me what the MAC address of 192.168.0

The IP address is not only implemented by the IP protocol, but also by many small protocols. The notorious ARP protocol is also one of them. Why is it notorious? Because the vulnerabilities and attacks against this Protocol have always been an important precaution for our security issues. I. Working Principle of ARP In the tcp ip protocol, each network node is identified by an IP address, and the IP address

There are two ways to map from IP addresses to physical addresses: tabular and non-tabular. ARP specifical

Recently, the ARP virus has plagued almost all local networks, where network faults occur frequently and the network speed suddenly slows down. Moreover, when network connections are interrupted, the normal working order is affected, heavy traffic can paralyze the entire local area network and even cause irreparable losses. Therefore, how to take effective measures to prevent ARP viruses has become the top

ARP attacks implement ARP spoofing by forging IP addresses and MAC addresses, which can generate a large amount of ARP traffic in the network to block the network. ARP attacks mainly exist in LAN networks. If a person in LAN is infected with an ARP Trojan, the system infecte

Recently, many friends and customers of the server encounter ARP spoofing attacks, resulting in the site was linked to the Trojan horse. Because it is the use of ARP technology deception, so the host did not invade, the server to view the source of the page is not any horse code, but the site in the visit is all hung horse!At first, I don't understand. This is the network legend of

Recently, many Internet cafes in China have been disconnected for a short period of time (full or partial), but will be automatically restored in a short period of time. This is caused by a MAC address conflict. When the MAC address of a computer with a virus maps to a NAT device such as a host or vro, the whole network is disconnected. If it is mapped to only other machines in the network, then there is only a problem with this part of the machine. It is often used in legend games, especially p

Sniffing can be easily implemented in the Age of hub prevalence You don't need to do anything. The hub will automatically send others' packets to your machine. But that time has passed, and nowVswitchInstead of hubs, vswitches will no longer forward packets that do not belong to you, you can no longer easily listen to other people's information. (If you are not familiar with the hub and switch working principles, you can read the article 《Basic network knowledge: hubs, bridges, and switchesMachi

I. Working principle: A. Determine the illegal access MAC address in the network based on the DHCP Snooping or the manually formed MAC address and IP Address binding table. B. to prevent malicious ARP spoofing, the arp REQUEST packets of the interface can be limited. --- Tests show that arp requests and replies (including unreasonable
