In the current network environment, applications have become the main carrier of the network, and more threats to network security come from the application layer, which puts forward higher requirements for network access control. How to precisely identify users and applications, block applications with security risks, ensure normal use of valid applications, and prevent port theft has become the focus of users on network security. The Web application protection system is also called the website

After all the system security defenses are completed, I am afraid SQL injection, cross-site attacks, and other web Application Layer defenses are left behind. This is also the most troublesome thing for the majority of webmasters, A few days ago, I wrote "Security treasure architecture technology speculation and advanced network security defense" to explain the simplest high-performance defense method, which can be slightly modified based on my own situation, we can deal with most of the attacks

Adversarial ROBOT: Build a WAF that combines front and back ends We have introduced some man-in-the-middle attack solutions that combine front and back ends. Due to the particularity of Web programs, the participation of front-end scripts can greatly make up for the shortcomings of the backend, so as to achieve the traditional hard-to-achieve effect. Since the attack can be used for attacks, similar ideas can also be used for defense. If we integra

Abstract: Author: bugcx or anonymous WAF (Web application firewall) has gradually become one of the standard security solutions. With it, many companies do not even care about Web application vulnerabilities. Unfortunately, not all WAF services cannot be bypassed!

In the "Out of the Web application firewall misunderstanding" series of articles (i), we analyzed and discussed who can protect Web applications, in this article we will focus on the characteristics and application of WAF. As early as 2004, some foreign security vendors put forward the concept of Web application firewall (Web application Firewall, WAF), and began a step-by-step attempt (such as Barracuda N
