show the percentage of packets distributed by size range. The content shown here shows that only 2% of the packet size is between 33~64 bytes.Note that the number of visits to the website has plummeted. It is clear that no one has access to his Web server during this period of time. Xiao Li began to study exactly what had happened and how to fix the fault as soon as possible.Second, difficult questions and answers1. What happened to Xiao Li's Web server? What are the possible types of attacks?2

If the address has been disguised, how can he track the attacker?Event InferenceWhat kind of attack did Xiao Li's Web server suffer from? This attack is done by continuously sending UDP packets through a echoing port (Echo Port number 7). The

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

After the emergence of WLAN technology, "security" has always been a shadow around the word "wireless". Attacks and cracking against security authentication and encryption protocols involved in wireless network technology have emerged. Currently, there may be hundreds or even thousands of articles on how to attack and crack WEP on the Internet, but how many people can truly break WEP's encryption algorithm? Next I will introduce some knowledge about W

SYN attack schematic diagram: TCP has to shake hands three times before passing data, and the SYN attack is to send a SYN packet to the server and spoof the source IP address.When the server receives the SYN packet, it joins the backlog queue and sends the SYN-ACK packet to the source IP and waits for the ACK packet to complete the three handshake connection.Because the source IP address is forged without

According to statistics, in all hacker attacks, SYN attacks are the most common and most easily exploited one of the attack methods. I believe many people still remember the 2000 Yahoo site attack case, the hacker was using a simple and effective SYN attack, some network worm with SYN attack caused greater damage. This

Author: BIBI Whenever we think of hackers, hackers tend to be such a portrait: A lonely person, sneaking into someone else's server to sabotage or steal other people's secret information. Perhaps he will change our homepage, who will steal the customer's credit card number and password. In addition, hackers will attack customers who visit our site. At the same time, our server has become his accomplice. Microsoft called the

You can also quickly upgrade it. Edit it now! A buffer overflow attack is an attack that exploits the buffer overflow vulnerability. Buffer overflow is a very common and dangerous vulnerability, which is widely used in vari

1, Attack principle The principle of the CC attack is that the attacker controls some hosts to keep sending a large number of packets to the other server, causing the server to run out of resources until downtime crashes. CC is primarily used to attack pages, everyone has this experience: when a Web page visits a very large number of times, open the page is slow

recently took a little time to "the King of Destruction-ddos attack and the depth of the prevention of the analysis" to read it, frankly, this book is relatively simple, can be said to be an introductory book, of course, for me this kind of DDoS smattering people, is also a good book, at least I learned something. DDoS is a shorthand for distributed denial-of-service (Distributed denial of service, DDOS), and the name shows that its

Ultimate defense guide-DDoS Attack Summary: As recent DDoS attacks have become more and more widespread, this site invites our honorary technical consultant and network security expert Mr. Lonely jianke to write this article exclusively based on years of experience in defending against DDoS attacks, this article not only elaborates on the concept of Distributed Denial of Service (DDoS) attacks, popular DDoS

DDoS attacks are essentially time-series data, and the data characteristics of t+1 moments are strongly correlated with T-moments, so it is necessary to use HMM or CRF for detection! --and a sentence of the word segmentation algorithm CRF no difference!Note: Traditional DDoS detection is directly based on the IP data sent traffic to identify, through the hardware firewall. Big data scenarios are done for slow DDoS attacks.Difficulty: In the attack, th

I believe you have heard of DoS attacks, DDoS attacks, and DRDoS attacks! DoS is short for Denial of Service and DDoS is short for Distributed Denial of Service and Distributed Denial of Service. DRDoS is short for Distributed Reflection Denial of Service, this is the meaning of Distributed Denial-of-Service. However, the most severe attack method in these three cases is DDoS. Although the DRDoS attack is a
