0 × 00 PrefaceAt the beginning of, an SQL group injection attack was launched. Hackers swept away the asp, asp.net, and MSSQL websites around the world. Because MSSQL supports multi-statement injection, hackers can use a combined SQL statement to automatically tamper with the field content of the entire database and perform webpage Trojan attacks without any difference on the website.

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 rando

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.

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.

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
