workarounds: Limit access to Junos Space from only trusted networks
Use administrative jump boxes with no internet access and employ anti-scripting techniques.
In addition to the recommendations listed above, it is good security practice to limit the exploitable attack surface of critical infrastructure networking equipment. Use access lists or firewall filters to limit access to the devices administrative interfaces only from trusted, administrative networks or hosts.
