The core switch is currently the most commonly used networking device, and its security performance is also good. However, improper use may also cause some problems. There are blue sky and white clouds on the Internet, there is also a hidden underflow, if you do not pay attention to it, a variety of network viruses may be "not please come ". In the event of a network virus attack on a LAN, the Internet access speed is not normal. In severe cases, the

Due to the inherent deficiency of IIS, it is easy for intruders to identify the category of the system. Believe it? Telnet to a system with IIS installed and enter a get command to check what is going on? As shown in 1, the system tells you without reservation that this system uses IIS5.0, which indirectly indicates that "I" is Windows 2000. Figure 1 A little scared? Okay. Now let's attack the virus and let the IIS display information be changed accor

I. Distributed blocking services (distributed denial of service) DDoS is a special case of DoS, hackers use multiple machines to attack at the same time to prevent normal users to use the service. After hackers have invaded a large number of hosts beforehand, to install DDoS attack on the victim host to attack the target; some DDoS tools use a multi-level archit

The following article describes the prevention of four levels of attack to ensure the security of Linux servers, if you are against four levels of attack to ensure that the Linux server security is curious, the following article will uncover its mystery.

Dos attacks, DDoS attacks, and DrDoS attacks believe that everyone has already heard of it! DOS is the shorthand for denial of service, which is denial of services, and DDoS is the distributed denial of service is the short of distributed denial-of-service, and DrDoS is distributed Reflection denial Abbreviation for service, which is the meaning of distributed reflective denial of service. But the most powerful attack in this 3 is DDoS, the DrDoS

With the expansion of Linux enterprise applications, there are a large number of network servers using the Linux operating system. Linux server security can be more and more attention, here according to the depth of the attack on the Linux server in the Level form, and propose different solutions. The definition of a Linux server attack is that an attack is an un

1. Overview With the development of information technology, various network security problems are emerging. Although WLAN has the advantages of easy to expand, flexible to use and economical, it is particularly vulnerable to the security aspect because of its use of RF working mode. The wireless network based on ieee802.1l has been widely used, but it has also become an attractive target. Due to the serious defects of IEEE802.11 's WEP encryption mechanism and authentication protocol, a series

or all of the control of a host computer!Because such attacks make it possible for anyone to gain control of the host, it represents a very serious security threat. The reason why buffer overflow attacks become a common security attack is that buffer overflow vulnerabilities are too common and easy to implement. Furthermore, the buffer overflow is the primary means of a remote attack because the buffer ove

1. study the principle of buffer overflow, at least for the difference of two kinds of databaseBuffer overflow means that when the computer fills the buffer with the number of bits of data, exceeding the capacity of the buffer itself, the overflow of data over the legitimate data, ideally, the program to check the length of the data does not allow the input of characters beyond the length of the buffer, However, most programs assume that the data length always matches the allocated storage spac

According to statistics, in all hacker attacks, SYN attacks are the most common and most easily exploited one of the attack methods.
