# Double check inbound transactions

Use the **glide.security.strict.updates** property to enable double-checking of security on inbound transactions during form submission. When you set this property to **true**, it adds an extra layer of table validation before a form renders in the browser.

The **glide.security.strict.updates** system property provides an extra layer of security on form submission / field updates by ensuring only users with the proper permissions are allowed to update a form. If **glide.security.strict.updates** is not set to the recommended value of **true**, then updates are not strict meaning they are able to modify fields visible to them regardless of whether they have the appropriate permissions.

Ensure that the property **glide.security.strict.updates** exists in the System Properties \[sys\_properties\] table and 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.
