IPFire brings super secure Linux to the masses

By

Most folk know if they want a secure gateway between the Internet and their home or business they should use Linux for maximum protection. The new IPFire distribution seeks to take security to the highest level while also making things a breeze for the less experienced to set up.

Linux can be daunting for those from the Windows world, more used to point-and-click interfaces than a plethora of command-line instructions, and for those without a network security background the general task of establishing a secure server may not be straightforward.

IPFire seeks to address both these, as expressed in its tagline, 'security gone easy!'

In particular, IPFire has been designed to serve as a policeman and traffic copy intercepting and inspecting all the traffic between your network and the Internet. In this regard it essentially turns a computer into a sophisticated firewall and router appliance.

This is achieved by bundling a pre-configured collection of top-notch open source security tools as well as IPFire's own custom-built packet manager called Pakfire. Pakfire permits close inspection of TCP/IP packets as they come in to the network and thus the ability to make complex decisions based on them. Pakfire supports a plug-in architecture so it can be easily extended by others.

IPFire isn't just a burn, mount and forget distro; effort has been expended by the designers to ensure it keeps up to date with security and regulatory patches and changes.

In addition, the team behind IPFire has put in a lot of work to make sure the whole lot is glued together in a cohesive user interface which aims to be clear from beginners through to experienced old hands.

IPFire has downloadable images to suit CDs, USB sticks, embedded device and even a ready-to-run Xen virtual machine.

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
