What s the difference between IFrame and Frame

Question

Looking at options for embedding the 3D Secure page inside my own order form  I came across the following    Some commerce sites will devote the full browser page to the authentication rather than using a frame  not necessarily an iFrame  which is a less secure object anyway     from http   en wikipedia org wiki 3-D Secure  Can someone give me the lowdown as to why iframes are less secure  and cause problems  as opposed to normal frames   And what are the basic differences   The way I see it  iframe is the way to go

The difference is an iframe is able to  float  within content in a page  that is you can create an html page and position an iframe within it  This allows you to have a page and place another document directly in it  A frameset allows you to split the screen into different pages  horizontally and vertically  and display different documents in each part   Read IFrames security summary

iframes are used a lot to include complete pages   When those pages are hosted on another domain you get problems with cross side scripting and stuff  There are ways to fix this   Frames were used to divide your page into multiple parts  for example  a navigation menu on the left   Using them is no longer recommended

The only reasons I can think of are actually in the wiki article you referenced to mention a couple         The  Verified by Visa  system has drawn some criticism  since it is   hard for users to differentiate between the legitimate Verified by   Visa pop-up window or inline frame  and a fraudulent phishing site         as of 2008  most web browsers do not provide a simple way to check   the security certificate for the contents of an iframe    If you read the Criticism section in the article it details all the potential security flaws   Otherwise the only difference is the fact that an IFrame is an inline frame and a Frame is part of a Frameset  Which means more layout problems than anything else

While the security is the same  it may be easier for fraudulent applications to dupe users using an iframe since they have more flexibility regarding where the frame is placed

Inline frame is just one  box  and you can place it anywhere on your site  Frames are a bunch of  boxes  put together to make one site with many pages

User · Answer

IFrame is just an  internal frame   The reason why it can be considered less secure  than not using any kind of frame at all  is because you can include content that does not originate from your domain   All this means is that you should trust whatever you include in an iFrame or a regular frame   Frames and IFrames are equally secure  and insecure if you include content from an untrusted source
