Why this tool?
Douane is an application firewall that blocks unknown or unwanted traffic. It provides a more fine-grained filtering as it looks at the combination of application and used network ports. This is useful when allowing common browse traffic on port 80 and 443. Instead of all applications being able to use this port, only the ones that are granted access will be able to do so. When a new connection is not trusted yet, Douane will ask to allow or deny the traffic stream.
How it works
Douane will be active in the background and be listening for new connections. This is done using a custom kernel module and using the netfilter capabilities in the Linux kernel.
Usage and audience
Douane is commonly used for network traffic filtering. Target users for this tool are general public and system administrators.
