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 property is not set to the recommended value of true, then the remote instance test feature will allow internal port scanning which is a method bad actors can use to discover vulnerabilities in a network. It is then possible to enumerate all open ports on a given host, and in some cases pull response data which could lead to information leakage or unauthorized data access.  
Warnung:  
This is a safe harbor property, meaning the value can't be altered once it's changed. It is non-revertible.
