how to prevent spoofing

The power of ARP spoofing viruses does not need to be discussed by the author. In particular, many similar ARP viruses have the worm feature, making it more difficult to cope with it. There are many articles on the Internet that show you how to deal with the ARP spoofing virus in the enterprise intranet. However, in most cases, we need to filter or bind MAC addresses on core switches, what if we do not have

Transferred from: http://www.cnblogs.com/hkleak/p/5043063.htmlNote One: What is Ettercap?We use the two tools of Cain and Netfuke when it comes to web security detection, and the functionality is believed to be known to a few friends, but these two tools run under Windows.And Ettercap is running under Linux. In fact, the function is almost the same, I call it a sniffer tool, ARP spoofing, DNS, hijacking, intermediate attacks and so on. In short, this

ARP spoofing attacks are a common form of attacks. The Intranet of the attacked organization may slow or even stagnate the network due to ARP spoofing attacks. This article describes how to find out ARP spoofing attacks through network traffic detection through an example of a school's ARP spoofing attack, so as to sol

ARP viruses are also called ARP Address Spoofing viruses, which are a special type of viruses. This virus is generally a trojan that does not have the characteristics of active transmission and does not replicate itself. However, due to its attack, it will send forged ARP packets to the whole network, seriously interfering with the normal operation of the entire network, the harm is even more serious than some worms. When an ARP virus attack occurs,

For better understanding, let's look at an example. If you want to use a browser

The purpose of this article is to explain the implementation and Prevention Measures of IP spoofing to readers. It requires you to have a small amount of knowledge about Uni x and TCP/IP. If you do not have one, it does not matter. I believe the following instructions can give you sufficient background knowledge.IP spoofing is a complex technical attack suitable for TCP/IP environments. It consists of sever

Leave the second set for this article because so far, I have not completed a very important task. However, things keep improving. I will share with you the implementation principles and processes of the first step, and I will make some contributions to you. Of course, the code I implemented is written in Java, so those learning C ++ can only be used for reference. 1. ARP spoofing PrincipleI think you should be interested in knowing what is going on.

The Gateway ip address is 192.168.1.1Arp spoofing. in the exchange environment, the host is notified that the MAC address of the host is the gateway MAC address, send the packets sent to me by the spoofed host to the gateway, and then use the local machine to notify the gateway. Environment: The local ip address is 192.168.1.103. The spoofed host ip address

1. DescriptionARP Spoofing (ARP spoofing), also known as ARP virus (ARP poisoning) or ARP attack, is an attack technique for Ethernet Address Resolution Protocol (ARP). This type of attack can allow an attacker to acquire packets on the LAN or even tamper with the packets, and make it impossible for a particular computer or all computers on the network to connect properly. The first article to explore ARP

IP spoofing is also a very useful feature that LoadRunner itself with. Need to use IP spoofing reason: 1, when a certain IP access is too frequent, or the traffic is too large, the server will deny access requests, this time through IP spoofing can increase the frequency of access and traffic to achieve the effect of stress testing. 2, some servers configured lo

PrefaceWe know that during Intranet penetration, ARP spoofing, DNS spoofing, and other methods often have a great impact. In addition, due to the old technology, there are many defense software, in addition, many network devices gradually have the ARP spoofing defense function, which makes it difficult for our Intranet penetration.Recently, I used NetBios

[Anti-spoofing art]: Intrusion warning (1)After being interrupted for a long time, I wanted to update an article over the weekend. I didn't want to suddenly burn it to 39.5 degrees. I had to breathe my breath and breathe my breath. I went to the hospital to take an injection. Today, I finally got through it slowly, I quickly picked up the chapter I saw last Friday and kept a clear impression to record what I learned from this chapter. Previously, I in

[Anti-spoofing art]: attacker art (2)There are a wide range of ways for social engineering attackers to attack. In the previous article, we talked about how attackers can use seemingly harmless information to gain the trust of the target. This article introduces another way for attackers to gain the trust: provide help or seek help from the target. This article involves two chapters of the original book:-"Let me help you"-"Can you help me ?"1. help so

Describe the operations of DOS attacks and how to use IP Address Spoofing to conceal the identity of attackers. Step: 1) H3 initiates DOS attacks on the server to prevent the server from providing normal services. 2) but H3 uses its own IP address and MAC address as the source address for attack. The administrator can easily detect and block it. 3) a hacker first scans the addresses of other hosts on the ne

unless you are sure that the proxy server is reliable, but this is almost impossible. Speaking of this, it is more reliable to obtain the Client IP address. In my opinion, remote_addr is used to obtain the IP Address Source for direct requests, because this is the only reliable data. What if we trust the other two IP addresses on the proxy server and use the so-called real IP addresses on the network? The result is very bad. Hackers can easily forge proxy IPs and then blow up the voting data. T
