"The King of Destruction--ddos attack and prevention depth analysis"The development of cyberspace brings opportunities and threats, and DDoS is one of the most destructive attacks. This book introduces DDoS from a variety of perspectives, in order to answer some basic questions from the perspective of the attacker: who
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 pow
strictly limit the number of IP connections allowed by each site and the CPU usage time.CC defense should start with code. In fact, a good page code should pay attention to these things, as well as SQL injection. It is not only an intrusion tool, but also a DDOS gap, everyone should pay attention to it in the code. For example, a server has launched a 5000-line CC atta
because the protocol is relatively complex, so the effect is very obvious, and protection is very high, such as the CC attack on the game server, is to use the online game itself some application protocol vulnerabilities.

because the protocol is relatively complex, so the effect is very obvious, and protection is very high, such as the CC attack on the game server, is to use the online game itself some application protocol vulnerabilities. The damage of large-ddos attacks has also changed, and the previous DDoS attacks have been mainly
by a DDoS attack. Hackers use all computers in the network to attack victims, instead of occupying these spoofed hosts in advance. This is a Smurf attack. DRDoS attacks are based on this principle. Hackers also use a special packet sending tool to first send SYN connection
According to the network related news, recently Beijing network supervisor and Interpol, successfully cracked a network security company employees using hacker means DDoS attacks, to a domestic signature network game server launched a flood trip, lasted one months of server paralysis to the game directly caused by millions of economic losses. During the attack, the game security engineer allegedly changed t
February, foreign hacker organizations launched a high-volume DDoS attack on XBOX, one of the world's largest online gaming platforms, which had a business impact for up to 24 hours. In early March, domestic game manufacturers were also under heavy DDoS attacks. It seems that 2016 is destined to be an extraordinar

need to take advantage of any hacker's support to launch a denial of service attack. News from Warisin shows that a zombie network can be rented from criminals for as long as 8.94 dollars per hour. Why pay if you can launch a DDoS attack with a dummy software? The news from the Internet Storm Center, an association of Systems management, networks and security, s
combined with worms and botnet to develop into a network blackmail tool for automatic multicast, centralized controlled and distributed attacks. According to founder Information Security Technology Co., Ltd. experts introduced, DOS from defense to tracking, has been a lot of methods and theories. For example, syncookie,hip (history-based IP filtering), ACC control, and other tracking aspects also put forward a number of theoretical methods, such as I
DDoS attacks are not as simple as we think, and are not something that Python programmers can do.To understand the hacker's use of DDoS attacks, we must know what is the most difficult reason to implement a DDoS attack?A simple sentence summarizes: "Python programmers have to master a certain intrusion skills." ”Here I
hosts, identify existing security risks, and provide corresponding countermeasures, which can reduce or even prevent hackers from using the host as a zombie. The security scanning tool can detect and delete DDoS attacks installed by hackers on the host. Security scanning tools should be upgraded with the evolution of attack methods.2.1.2 use NIDS and snifferWhen
of vehicles is also limited. Users online access server needs to occupy a certain amount of bandwidth resources of the server, aside from memory, only 200Gbps of pure traffic attacks, the number of ordinary users to use the number of home computers, the amount may be between 150,000 million, or even higher, so many malicious access, while occupying server bandwidth, Memory resources, and the server is paralyzed by resource exhaustion. How to
Here is the actual process of a SYN flood attack I simulated in my lab This LAN environment, only one attack aircraft (Piii667/128/mandrake), is attacked by a Solaris 8.0 (Spark) host, network device is Cisco's hundred Gigabit Switch. This is a Snoop record on Solaris prior to the attack, and Snoop, like Tcpdump, is a good t

proxy servers are sent, but there are many agents send this parameter. Detailed code:This will generate CCLog.txt, its record format is: The real IP [proxy IP] time, to see which real IP appears more often, you will know who is attacking. Make this code a conn.asp file, instead of the files that connect to the database, so that all database requests are connected to the file, and the attacker can be found immediately.4. Another way to do this is to redirect the statement that needs to be made t
DDoS attack tracking Distributed denial of service (DDoS) attacks are a serious threat on the internet. However, the memory-free functionality of the Internet routing mechanism makes it difficult to trace the source of these attacks. Therefore, there is no effective way to deal with this problem so far. The common way to trace

By March, the site incredibly to the second home page Baidu, although only persisted for three days, immediately fell to the fifth, but those days every day has 100,000 IP, at that time cut a map (with the plug-in of shielding ads, so no promotional links). The website traffic is big, some peo
