  • Last updated: 2013-03-12
  • Percentage of completion: 10%
  • Firewalld milestones for rich language and lockdown features
    • Milestone 1: Rich config language via config files; minimal lockdown ~ end of March (will be 30%)

Detailed Description

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.

Scope

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.

User Experience

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.

Dependencies

None.

Contingency Plan

This is a simple firewalld setting, which can be enabled or dropped easily.

Documentation

TBD

Release Notes
