Which of the following is one way to prevent a clickjacking attack?

A. Use input validation.
B. Set the X-FRAME-OPTION value to deny.
C. Implement fuzzing.
D. Use strong authentication.


B
Explanation: Most responsibility for preventing clickjacking rests with the site owner. When designing web site applications the X-FRAME-OPTIONS header is used to control the embedding of a site within a frame. This option should be set to DENY, which will virtually ensure that click jacking attacks fail. Also the SAMEORIGIN option of X-FRAME can be used to restrict the site to be framed only in web pages from the same origin.
