WAF Defense Capability Evaluation and tools This article describes how to evaluate a WAF from the defense capability of conventional attacks. A total of 16 attack types are covered, each of which ranges from the Use scenario (The purpose of the attack operation) to the injection point (where the vulnerability is generated, for example, most WAF comprehensively c

Compared with the industry's WAF scheme, we have a disadvantage in this scenario, such as: 1. Types of webserver Need to adapt to the latest webserver,webserver version of the mainstream once a major update or a new popular webserver, our door-keeper agent may need to be developed. Because of the complexity of the business, it may be necessary to iterate multiple versions to stabilize, such as the Nginx

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
