No Comments

Quick Reference

Element Code: SE-007

Issue: X-Frame-Options header not properly configured

Impact: Vulnerable to clickjacking attacks

Fix: Add X-Frame-Options: DENY or SAMEORIGIN

Detection: HTTP header inspection, security scanners

What Is This Issue?

Clickjacking embeds your site in an invisible frame to trick users into clicking. X-Frame-Options prevents your pages from being framed by other sites.

Why This Matters for Your Website

Clickjacking can trick users into unintended actions. This header is simple to implement and provides important protection.

How to Fix This Issue

  1. DENY: Never allow framing
  2. SAMEORIGIN: Allow framing by same origin only
  3. Consider CSP: frame-ancestors directive is more flexible

Tools for Detection

  • Security headers check: Verify X-Frame-Options

TL;DR (The Simple Version)

Add X-Frame-Options header to prevent your site from being embedded in malicious frames. Use DENY or SAMEORIGIN depending on your needs.
