Remediation Script (HTTP Header)
# SECURE REMEDIATION: Restrict framing
X-Frame-Options: SAMEORIGINFrequently Asked Questions
Why is X-Frame-Options required?
It prevents malicious sites from framing your login forms or configuration panels, preventing clickjacking.
Is X-Frame-Options obsolete?
It is superseded by CSP's 'frame-ancestors' directive, but still deployed for older browser compatibility.
What is the difference between DENY and SAMEORIGIN?
DENY blocks all framing, while SAMEORIGIN allows framing only by pages on the same domain.
