Anti-DDoS (distributed denial of service) attack system is to maintain the stability of the business system, continuous operation and high availability of network bandwidth to provide protection capabilities. However, since the 1999 Yahoo, ebay and other e-commerce sites were attacked by denial of service, DDoS has become a new security threat on the internet, which is very dangerous and very difficult to protect. Especially with the development of h

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 s

One, from DOS to DDoS Denial of service (denial of Service,dos) is a long-standing tradition. Since the Internet, there is a denial of service attack approach. As no major websites or institutions have been subjected to such attacks in the past, their inferior nature is not prominent. It was not until the early 2000 that Yahoo!, ebay and Amazon were stabbed in the face. In a typical Internet connection, when a user accesses a Web site, the client se

The following illustrated by the way to show you the PHP kernel exploration: Hash table collision attack principle. The recent hash Table collision Attack (Hashtable collisions as DOS attack) has been the subject of constant mention, and various languages have been recruited. This article unifies the PHP kernel source code, chats this kind of

CSRF (Cross site request forgery) is a network attack that can be sent to a compromised site without the victim's knowledge of the victim's name forgery request, thereby performing a rights-protected operation with no authorization. There is a lot of harm. However, this attack mode is not well known, many websites have CSRF security loopholes. This paper first introduces the basic principle of CSRF and its

Sigreturn Oriented Programming (SROP) Attack Principle I wrote an article last year to introduce the BROP attack. The response was quite good and helped many people understand this very smart attack principle. Of course, you can also go to my blog to see the replay of this attack.

1. Read attack Read attacks mainly include all attacks related to information retrieval from victims. Such attacks scan ports and vulnerabilities within the IP address range of the organizational structure, and finally obtain information from vulnerable hosts. 1. Reconnaissance recon Attacks: Reconnaissance recon attacks: these attacks are designed to enable attackers to obtain more information about victims. They can use active and passive method
