Hi, I have a question and I hope anyone could answer it:
Which of these is not a reason why securing server-side web applications is difficult?
1.Although traditional network security devices can block traditional network attacks, they cannot always block web application attacks
2.The processors on clients are smaller than on web servers and thus they are easier to defend
3.Many web application attacks exploit previously unknown vulnerabilities
4. By design dynamic server-side web applications accept user input that can contain malicious code.
Answer: Although traditional network security devices can block traditional network attacks, they cannot always block web application attacks
