# Implement the x-frame-options: SAMEORIGIN security header

Use the **glide.set\_x\_frame\_options** property to set the X-Frame-Options response header to SAMEORIGIN for all UI pages.

The **glide.set\_x\_frame\_options** system property controls the implementation of the security header X-Frame-Options: SAMEORIGIN. If **glide.set\_x\_frame\_options** is not set to the recommended value of **true**, then an instance will be allowed to be framed in an iframe of another page.

Ensure the property **glide.set\_x\_frame\_options** is set to **true**.
