What is this type of attack (that can use either HTTP GET or HTTP POST) called?


A. Cross-Site Request Forgery
B. Cross-Site Scripting
C. SQL Injection
D. Browser Hacking

Correct Answer: A

Explanation:

Cross-site request forgery, also known as one-click attack or session riding and abbreviated as CSRF (sometimes pronounced sea-surf) or XSRF, is a type of malicious exploit of a website where unauthorized commands are transmitted from a user that the website trusts.
Different HTTP request methods, such as GET and POST, have different level of susceptibility to CSRF attacks and require different levels of protection due to their different handling by web browsers.
