Label:black box Test 　　Black box test product software as a black box, only the export and the entrance, the test process as long as you know what to enter into the black box, know the black box will come out of what results can be, do not need to know the black box inside is if done. That is, testers do not bother to understand the software inside the specific composition and principles, as long as the user to look at the product. 　　For example, the bank transfer function, do not need to know h

After a half-day tutorial on the Internet, the web Authentication background is successfully connected today. Sort it out. In fact, we can connect to each other in just one minute.

Limit ". $_get[' C ';Then we can construct such an injection statement:01./?a=1+union/

I. About SQL injectionSQL injection is a common technique for invading Web applications. SQL injection is a result of changing the original SQL statement execution logic using the application system's programming vulnerability and the syntax characteristics of the SQL language.An attacker sends carefully constructed input data to a Web application that is interpreted as a SQL instruction, alters the original normal SQL execution logic, executes an attacker-issued SQL command, This ultimately all

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 dif

Who is the best choice? Web application protection is undoubtedly a hot topic. Because of the maturity of technologies and the increasing expectation of convenience, Web applications have become the mainstream carrier of business systems. The data value contained in the key business systems of "anjia" on the Web has aroused the favor of attackers. The Web vulnerability mining and attack tools circulating on the Internet have lowered the attack threshold, it also makes many attacks blind and rand

SQL injection, Web tampering, Web page hanging Horse and other security incidents, frequent occurrence.Enterprises and other users generally use firewalls as a security system of the first line of defense. But, in reality, they have such problems, such as the traditional firewall system can not respond to the current rapid outb

In the Blog Federation group before the simulation of CC attacks built on the Aliyun ECS on the blog, the results Yun Dun no response, and the site has been hung. This time deliberately look at the CC protection function on the cloud shield, found that some friends do not estimate the correct use of WAF. Therefore, in this article I simply sh
