I currently have configuration SRX with policies, but I want to add a new one using Security Design, but when I add and want to upload to SRX and when I click on View I see that Junos Space will delete all other policies. Can somebody tell me why does Junos Space deletes all existing firewall policies when I add a new policy using Security Design?
Security Design is the master for all security related config, if SD does not have the rules it will be deleted from device during update. To handle this, you can perform Import of config into SD and then work on the import policy. Goto Security Design Devices ->Select Device + right click-> Import.
