Finding ID	Version	Rule ID	IA Controls	Severity

Description
Frames that navigate across different domains are a security concern, because the user may think they are accessing pages on one site while they are actually accessing pages on another site. It is possible that a website hosting malicious content could use this feature in a manner similar to cross site scripting. This policy setting allows you to manage the opening of sub-frames and access of applications across different domains.
