Local applications or services are able to change the firewall configuration if they are running as root (example: libvirt). With this feature the administator can lock the firewall configuration so that either none or only applications that are in the allowed list are able to request firewall changes.
The lockdown feature is a very light version of user and application policies for firewalld and is turned off by default. Comprehensive user and application policies will be added later on.
Benefit to Fedora
An easy way to lock the firewall configuration for local applications.
Only needs changes in firewalld and it's components.
How To Test
Set the lock and use system-config-printer - it will try to open some ports.
The lock down settings defaults to disabled. If enabled the user can be sure that there are no unwanted configuration changes for the firewall from local applications or services.
This is a simple firewalld setting, which can be enabled or dropped easily.
Fedora 19 includes the latest firewalld version that supports the firewalld lockdown feature to be able to lock the firewall configuration for local applications.
