Validate remote host

reference australia Updated Sep 10, 2026 1 min read sc-validate-remote-host.md

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 true, then the Team Development Remote Instance test feature allows an internal network port scanning through 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.
