# Enforce strict security of session cookies

Use the **glide.ui.secure\_cookies** property to require properly formatted cookies

If **glide.ui.secure\_cookies** isn't set to the recommended value of **true**, then additional cookie security and strict cookie validation isn't performed.

Ensure that the property **glide.ui.secure\_cookies** is set to **true**.

**Warning:** This is a safe harbor property, meaning the value can't be altered once it's changed. It is non-revertible.
