With IPFire you can easily deploy many variations of it, such as a firewall, a proxy server or a VPN gateway. IPFire forms the base of a secure network. It has the power to segment networks based on their respective security levels and makes it easy to create custom policies that manage each segment.PFire employs a Stateful Packet Inspection (SPI) firewall, which is built on top of netfilter (the Linux packet filtering framework).
IPFire allows the network to be configured into different, separate segments. Each segment represents a group of computers who share a common security level.
Updates are digitally signed and encrypted, as well as can be automatically installed the IPFire package management system. The simple Pakfire package manager helps administrators feel confident that they are running the latest security updates and bug fixes for all of the components they utilize.
The package manager Pakfire offers the addon SquidClamAV - a virus scanner for the web proxy. This checks in real-time all web traffic for viruses, utilizing the ClamAV virus definitions and scanning engine.
It is possible to use IDS and IPS on the IPFire system. We call this system "Intrusion Detection and Prevention System" (or IDPS). A very important deputy of this system is Snort, the free Network Intrusion Dection System (NIDS). It analyzes the network traffic and if something abnormal happens, it will log the event. IPFire gives you the possibility to see it very explicitly in the web interface.
