Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use.

Business people often believe that in order to have a reliable system, you need reliable components. Using reliable components to build your network certainly helps, but it’s not essential. The task of an engineer is building a reliable whole out of less reliable parts; a well-engineered network built out of somewhat less reliable parts wins from a somewhat less well-engineered network built out of more reliable parts. Which is a good thing, because super-reliable devices and services are much, much more expensive than regular devices and services.
