IP<strong>Fire</strong> was designed with both modularity and a high-level of

The IP<strong>Fire</strong> development team understands that security means different things to
different people and certainly can change over time.
The fact that IPFire is modular and flexible make it perfect for integrating
settings out-of-the-box, meaning it's a snap to get going quickly!

The primary objective of IPFire is security.
As there is of course no one, single way to achieve network security, it is important
for a network administrator to understand their environment and what the term

(see the Firewall page for more information).

SquidGuard is a URL filter add-on which is connected via the redirector mechanism of the proxy.
The heart of SquidGuard is something called a "blacklist." This is a content control list created by the official site. These lists contain a number of categorically-classified websites and can be kept up-to-date automatically. There are different, independent
sources for pre-built blacklists available, which allow among other classes filtering for adult
content, shopping, warez, social networking, or sites containing violent/abusive content.

Individual extensions for particular domains or URLs can be set up on the IPFire web interface for
blacklists and whitelists as well. IPFire also offers a black list editor, that makes the editing

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.
</p>
- <p class="copy">
+

The additional protection to a conventional virus scanner lies in the fact that the files are transparently checked before ever making it to the client machine before the client machine's virus scan can be performed. So potentially-malicious files are blocked by
SquidClamAV before the client's actual download.

An Intrusion Dection System (or IDS), is a piece of software designed to detect attacks against computer systems
and networks. Thereby the IDS will analyze the network traffic and search for attack samples. If someone
scans the ports of the IPFire-System to see which services are available, the IDS will immediately notice it.
</p>
- <p class="copy">
+
+ <p>
An Intrusion Prevention System (or IPS), in addition to the detection system, will perform actions.
The IPS gets the information from the IDS and reacts accordingly. That means, recalling the example above with
the portscan, the system would automatically block the attacker immediately in order to prevent further inquiries.
</p>
- <p class="copy">
+
+ <p>
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.
</p>
- <p class="copy">
+
+ <p>
For automatic prevention, IPFire has an add-on called Guardian which can be installed optionally.
</p>

+
+ <p>
An IDPS is a wise addition to the normal packet filter. It makes intelligent decisions about
incoming and outgoing network traffic and how to deal with it.

+ <h3 class="text-center">{{ _("Quality of Service") }}</h3>
+
+ <p>
Quality of Service (QoS) is able to save the quality of a service on one internet connection. This
means that on a highly-utilized internet connection, a service (for example VoIP) gets a stable size of bandwidth,
to transfer the information without delay and without loss. This is at the expense of the other
data flows on the line, which is tolerated, albeit transmitted more slowly (such as a file upload to an FTP server).
</p>
- <p class="copy">
+
+ <p>
QoS does not only increase the functionality of real-time services, but also offers a little bit of overall improvement. For example:
</p>
+
<ul>
<li>
<strong>Connections establish much faster.</strong>
Every service gets a minimum, guaranteed amount of bandwidth.
</li>
</ul>
- <p class="copy">
+
+ <p>
For the classification of the packets, a Level-7-Filter is used. It also analyses the content, as well as the source-ports/IPs, and destination-ports/IPs of the packets. With that analysis, it will decide if it's a long download or a real-time
protocol and then subsequently determines the optimal use of the connection.
</p>
- <p class="copy">
+
+ <p>
To put all in a nutshell, QoS reduces the latency and packet loss of an
internet connection. This is certainly a function that you don't want to miss where bandwidth is limited.

IPFire offers several options for the integration of wireless clients. First, an access point can

Wireless card support in IPFire is excellent. The drivers in the stable kernel are very up-to-date
and IPFire therefore supports a significant amount of WLAN cards.
