Security concerns drive Carrier Grade Linux
Check out an in-depth article recently added to the site – Security concerns drive Carrier Grade Linux
A previous article we carried on CGL – Carrier Grade Linux 4.0 – Raising the bar – proved very popular, so he we hope this one is equally appreciated!
Increased concern about hacking and the security of network equipment is driving more operators to look at using carrier-grade solutions based around Linux, writes Glenn Seiler, of Wind River, Networking Solutions.
Network equipment, whether for a phone system, digital broadcast or wide area or enterprise network, must have high reliability and high availability. Traditionally, network equipment companies have provided this through proprietary architectures, but they have been moving to Linux and open source solutions over the past few years.
These solutions vary in effectiveness, and increasingly it is security concerns that are the major risk for network outage. Operators must find ways to protect their systems against a wide range of attacks in order to provide the maximum availability. This can be done through a combination of hardware redundancy and hardened software, but the right implementation is needed to get the most effective solution that provides the maximum availability.
