1. Common DDos attack types SYN Flood: it is currently the most popular DoS (DoS attacks) and is a type of TCP connection request that uses TCP protocol defects to send a large number of forged TCP connection requests, so that the attacked party's resources are exhausted (the CPU is full or the memory is insufficient. Smurf: This attack sends a packet with a specific request (such as an ICMP Response Request) to a subnet broadcast address, and disguis

To go to the bank to do business examples:Network layer DDoS is to let the road to the bank become congested, unable to get the people who really want to go to the bank, often use the protocol as a network layer, such as TCP (using three handshake response to wait and limit the number of computer TCP connections), etc.The application layer DDoS is to consume the bank's business resources, such as using HTTP

Simple and Convenient! The AVR Microcontroller has many advantages. I am also a loyal supporter, from 51 to AVR. I also learned PIC in the middle. I bought a learning board, LCD screen, and many other things when I was a beginner at 51. After my experience, when learning AVR, I started from the self-made download line. Note that this is just the beginning. Simple things have some limitations, but it is very useful for beginners, with it, you can start to learn the AVR single-chip microc

suspected that the data being transmitted is not BASE64 encoded but encrypted control information communication data packets (if such a rule is implemented, the data transmission on ports 20, 21, and 80 must be excluded ). 3. How should we survive and continue to provide normal services when dealing with DDoS attacks? As we can see from the previous introduction, if the hacker attack scale is much higher than your network bandwidth, device or host ca

DDoS (Distributed denial of service) attack is a simple and fatal network attack using TCP/IP protocol vulnerability, because the TCP/IP protocol is unable to modify the session mechanism, so it lacks a direct and effective defense method. A large number of examples prove that the use of traditional equipment passive defense is basically futile, and the existing firewall equipment will be paralyzed due to limited processing capacity, become a network

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

Preface: Robert C. martin summarizes the principles that should be followed in Object-Oriented Design (OOD). These principles are called "prinles les of OOD ", for more information about principles of OOD, see object menter. This article introduces the interface separation principle in "Principles of OOD": interface segregation principle (ISP ). You can view the original interface segregation principle (ISP

content of the site is the ISP (Network service provider) and WiFi provider's usual profit means.For example, some hotel networks, mobile networks will insert ads or other tracking cookies into the websites that users visit. Legitimate business typically does not inject malicious code into the site, but it does not mean that others on the Internet are not able to do so. If an attacker can obtain network location privileges like ISPs, such as network

In addition, many of the 7.7 chips now support in-chip Boot programs in System Programming (

The ISP is an abbreviation for Image Signal processor, the full name is the image processor. In the whole process of camera imaging, it is responsible for receiving the raw signal data of the photosensitive element (sensor), which can be understood as the first step process of photographing and recording the whole camera, which plays an important role in image quality.High-pass 8974 photo display process to clearly see the location of the

ISP -- Interface Segregation Principle, segregation 1. ISP Overview (ISP -- Interface Segregation Principle ): It is better to use multiple dedicated interfaces than to use a single total interface. The dependence of a class on another class should be based on the smallest interface. An interface represents a role and should not assign different roles to an inter

I scanned it with NMAP and found that most of them are[Url = http://www.microsoft.com/china/]Microsoft[/Url]It seems that all of them are "zombie" by OWN ". Zhang Damin estimated that there are about 40 thousands or 50 Thousands different IP addresses in the attack source. The log also contains many spoofed IP Source Address packets. For a mo

Among the many stationmaster also can exist infighting thing. In particular, our personal webmaster, due to limited technical and financial resources, very easy to use on the host, VPS after the attack did not have the ability to defend, leading to our host or VPS to our account suspension, IP hangs and so on.
