Do I need a tool to track and block code injection attempts in ASP .NET WebForms pages?

Question

Programming

I have a small project that monitors and blocks code injection attempts in ASP .NET WebForms. Do developers need such functionality?

There is a server control that intercepts requests to the page on which it is located. Requests are handled by the element, XSS and SQL Injection in requests are nullified.
In the plans: issuance of information on attacks to the Web console.

Answer 1

ASP.NET WebForms already has a similar mechanism built in.
IMHO SQL injections are not very relevant now.
XSS yes, interesting, but I don’t know how acute this problem is.
