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

For example, to test the union, then we use%55 that is U 16 encoding to replace U,union written%55nion, combined with case can also bypass s

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! This article will show you how to use the sqlmap injection tool to bypass WAFS/IDSS. SVN download the latest version... Author: bugcx or anonymo

1, HPP http parameter Pollution http parameter pollution means that the server side usually does some processing when submitting two parameters of the same key value in the URL. For example, Apache is going to take the last argument, for example: user.php?id=111id=222 If you output a $_get array, the ID's value will only take 222, i.e. the extra value submitted on the URL overrides the previous value. 2, a CTF topic http://drops.wooyun.org/tips/17248 About the injected

Web application firewall (WAF), translated as web application firewall, is mainly used to block attacks against WEB applications. Su baozi talked about his thoughts on WAF. You are welcome to make bricks and supplement them. 1. Necessity Practical Application: enhances awareness of the security status of WEB apps, controls web APP risks to a certain extent, and makes up for technical and implementation sh

App Gateway on Azure is a seven-tier load balancing service, and WAF is an extension of App Gateway services. The seven-tier load balancer adds the functionality of the WAF to protect the HTTP service in the background.Azure WAF is based on the WAF functionality implemented by the open source modsecurity owasp core rul

Recently on new projects, to build nginx to ensure security, the decision to install the WAF module, the following is the specific steps, first download the required installation package, for each installation: wget http://luajit.org/download/LuaJIT-2.0.3.tar.gz tar-zxvf luajit-2.0.3.tar.gz cd LuaJIT-2.0.3 make Make Install Then download the Nginx, wget http://nginx.org/download/nginx-1.7.6.tar.gz TAR-ZXVF nginx-1.7.6.tar.gz

Translation: pnig0s _ Small PLast week, I was invited to team up for a CTF flag race organized by CSAW. because of my wife and children, I can only pick one question related to Web vulnerability exploitation, called "HorceForce ". this question is worth 300 points. The general background of this question is that you have a low-privilege account and need to find a way to obtain administrator permissions.Of course, there are many ways to introduce how to pass the customs clearance, but I want to s

More and more servers will be added to waf. How to bypass: Waf is suitable for code layer separation, that is, it is not specifically customized, it also prevents General injection or cross-site. The following is a case study: When encountering such a server, he has a page with the search function. If the request is submitted as post in the search, the modified characters are displayed in the URL. For

I have been in charge of WAF testing for two years. As a product independently developed by lumeng, I watched her grow up. Despite the occasional stress of testing, every time I think of your progress, I am confident. Barracuda published the WAF of bs Green League on their official website, saying that it is the difference between QQ and BMW. I think, as a big brother barracuda, I have been in the
