Recently, the project was launched. A third-party company was invited to perform a penetration test and multiple XSS attacks were detected. Because we have used URLFilter to filter special characters for URL Get requests, the Get request vulnerability has been blocked. However, for Post requests, considering the existence of form submission in our project, rich text editing and other functions, dare not rashly use Filter to Filter keywords.To solve the above problem, we adopted AntiSamy, an open

This topic is the content we shared in the OWASP Hangzhou region security salon at the end of 2013. Here we resummarized the overall content of this topic and formed a text version. In this article, the case and response experience of DDoS come from the actual scenarios of a customer service system with a high market share, we analyze the costs, efficiency, and specific architecture design (selection, configuration, and optimization) to cope with diff

How to Prevent SQL Injection in PHP applications SQL injection is a technology used to control database queries, which often results in loss of confidentiality. In some cases SELECT' Attackers can take down the server, and code injection (including SQL, LDAP, operating system commands, and XPath injection technology) remains in the top 10 of OWASP vulnerabilities for many years. More people share their knowledge about application security. Unfortuna

and they will also make security mistakes. This idea helps developers avoid or reduce security risks and avoid losses to the company. Everyone will make mistakes. If the developer finds the problem before the hacker finds the vulnerability, the problem is not big. When developers and Software testers test and audit Web applications, or before the enterprise is put into use, developers or testers may use the well-known open-source tool owasp zap to sc

activity. capture a normal request packet first, remove the Referer field, and submit again. If it is still valid, there is basically a problem. Of course, the number of parts may contain the number of parts that cannot be preemptible (for example, userid or something). At this time, it depends on whether the number of parts that cannot be preemptible can be obtained through other means, such as flash. If yes, the problem persists. Also, try to change post to get, because some programs do not d

Of course, the parameter may contain unpredictable parameters (such as userid or something). At this time, it depends on whether this unpredictable parameter can be obtained through other means, such as flash. If yes, the problem still exists. Also, try to change post to get, because some programs do not distinguish get/post.The functions and return forms of applications are differ

Understand XSS attack principles After reading the HTML security list written by cool shell I suddenly wanted to write a quick tutorial on XSS. Let more people know what XSS security vulnerabilities are Before understanding XSS, you must know the principle of "session ". Simply put, after a member successfully logs in, the website will give the browser a "token 』 After this token is taken to the website, it will be considered as logged on Next is the simplest process of XSS.

authentication error information may cause dictionary attacks or brute-force cracking. Therefore, we should give a common error message as much as possible. In addition, to prevent brute-force attacks, we can set the following rules: -The first Logon Failed. The next logon interval is at least 5 s. -The second Logon Failed. The next logon interval is at least 15 s. -The third logon fails. The next logon interval is at least 45 s. -The fourth Logon Failed. The graphic Verification Code CAPTCHA i

Software Security Testing is the most important way to ensure the security of software. How to conduct efficient security testing has become a topic of attention in the industry. Years of security testing experienceWe are advised that the necessary conditions for doing a good job in software security testing are: first, fully understanding software security vulnerabilities, and second, having efficient software security testing technologies and testing tools. I. Analysis of major security vulne

circumstances it's a legal requirement. WAI-ARIA and WCAG 2 are good resources in this area. Don't make me think Security It's a lot to digest but the OWASP development guide covers Web Site security from top to bottom. Know about Injection especially SQL injection and how to prevent it. Never trust user input, nor anything else that comes in the request (which has des cookies and hidden form field values !). Hash passwords using salt and use
