Today is July March 8. I wish all my female young and beautiful forever! IP Address Spoofing is a hacker attack method that was announced long ago. I wrote some posts in this regard during my career as the webmaster of the red alliance. Unfortunately, the posts are not classic enough, so there are no traces on the Internet. I have seen several articles in this area recently, which reminds me of this. An ar

There are similar demands in Politics and Law networks and e-government affairs networks. How to provide a logically isolated, secure, and reliable virtual

A denial of service attack is an attacker trying to get the target machine to stop providing service or resource access. These resources include disk space, memory, processes, and even network bandwidth, preventing access for normal users. In fact, the consumption of network bandwidth is only a small part of the denial of service attacks, as long as the target can cause trouble, so that some services are suspended or even host panic, are a denial of service attacks. The denial of service attack

Tm3yShell7 blog We know that TCP/IP is based on different levels of addressing, and the information to be transmitted is often routed to the corresponding subnet Based on the ip address, then, find the host based on the mac address in the subnet. It can be seen that the host knows that the data does not require an ip layer route when it ensures that the target ho

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-

Principles of ip Spoofing and theftThe IP spoofing technology is complicated. It is not easy to figure out a tiger as a cat. However, as a conventional attack method, it is necessary to understand its principles, at least for your own security defense, and it is easy to defend against attacks. Assume that the customer

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
