# Validate remote host

Set the property to true to prevent bad actors from using internal port scanning in your network.

If the **glide.update\_set.remote.check\_host** system property is not set to the recommended value of **true**, then the Team Development Remote Instance test feature will allow an internal network port scan by providing positive/negative error messages.

Ensure that the property **glide.update\_set.remote.check\_host** 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.
