It provides 7x24 technical support for engineers and can provide on-site services as soon as

insecure browser-thin client brings two challenges: reducing application security and increasing security costs. Many web Front-end applications are not even considered to be attacked during development .. In this context, a new technology, Web application firewall. It can effectively reduce the implementation cost of website security. Barracuda

The simplicity and complexity of the user's network topology and the ease of user application are not the criteria for deciding whether or not to use a firewall, but a fundamental condition to determine whether a user is using a firewall is the user's need for network security! The background of the emergence and existence of two kinds of equipment is different

Networks that install a variety of security technologies are relatively well protected, while hackers and other malicious third parties are launching attacks against online business applications. Companies are configuring Web application Firewall (WAF) technologies to protect their online applications, and software developers ' negligence of security factors has

Editor: "In nine to 12 months, it will be widely used ." This is a long time on the speed-first Internet. Currently, attackers do not need to have a deep understanding of network protocols by using attack software that is everywhere on the Internet, such as changing the Web site homepage and getting the administrator password, damage the entire website data and other attacks. The network layer data generated during these attacks is no different from the normal data. Traditional firewalls have no

The next generation of firewall wins the application layer, and the next generation wins the application layer. Why is next-generation firewall superior to application layer? Almost no one doubts about the important position of firewalls in the procurement of all security e

webshell Scanning Safe3 web application firewall (WAF) is the first comprehensive web anti-virus software in China that can scan webshells completely. Because the software uses the intelligent script parsing and scanning engine, the detection and removal rate leads similar products in China.

With the full application of Internet Web technology, for Web application firewall, all security enterprises are excited due to the market blowout. However, it should be noted that not all the "Boxes" that provide protection for Web servers are Web application firewalls. In fact, a standard Web

obtain the original user account information. Tampered parameters or urls: web applications usually embed parameters and URLs in the returned web pages, or use authorized parameters to update the cache. Hackers can modify these parameters, URLs, or caches so that the Web server returns information that should not be leaked. Buffer overflow: the application code should check the length of the input data to ensure that the input data does not exceed th

difficult to strike a balance between the two. At present, most websites use this technology. They also understand the problems, but there is no better technology to replace it. Imperva's SecureSphere Web Application Firewall uses new protection methods, which not only effectively makes up for the shortcomings of traditional protection methods, but also has many new features. As a new Web

WAF, mainly to enhance the protection of web-specific intrusion methods, such as DDoS protection, SQL injection, XML injection, XSS, etc. Because it is an intrusion of the application layer rather than the network layer, it should be called Web IPS from a technical point of view, notWebApplicationFirewall . Because the focus is on anti- SQL injection, others are called SQL firewalls. in computer networks, a

also increased the automatic mode, so that the product can automatically learn the background server architecture, and even automatically recommend reasonable deployment or protection of the user model. The Barracuda Web application firewall is easy to use and is also embodied in its powerful logging capabilities. Through the log, users can see why a certain network browsing behavior is blocked, why is al

tampering, information leakage, Trojan horse implantation and other malicious network intrusion behavior. This reduces The likelihood of the Web server being attacked. Timely patchesPatching web security vulnerabilities is the biggest headache for Web application developers, and no one will know what kind of vulnerabilities the next second will bring to the Web application. Now the

Translator: Liu DaningOne advantage of application next-generation firewall (NGFW) is that it can improve Application Awareness and granularity when setting and managing policies for specific application elements. In contrast, the old-generation firewall relies on the ports

passage of some packets, it must be safe because the packets have been discarded. But in fact the firewall does not guarantee that the approved packets are secure, and the firewall cannot tell the difference between a normal service packet and a malicious packet, so the administrator is required to ensure that the packet is secure. The administrator must tell the firew
