Network Security
Today with the advent of the Internet most networks are in some way connected together. Although this makes it possible to communicate freely across the world and to have access to any information you need at your fingertips it also creates great risk. When we use our networks to control important manufacturing processes, monitor water levels in reservoirs or run our power stations we can not afford to allow unauthorised users access to these networks. It is not just malicious incursions that must be prevented; statistically more networks are compromised by accidental means. To prevent this from happening RedFox offers several layers of security.
RedFox itself has an inbuilt firewall so can be used as a barrier between internal departments of a company or as a barrier to the Internet.Traffic crossing this threshold can be carefully controlled to protect the mission critical network.
If NAT (Network Address Translation) is used RedFox will hide the IP address of any device in the protected network whilst it communicates with device in an unsecured network meaning that the IP address of a particular device can never be found and attacked.
RedFox can act as a VPN server allowing IPsec tunnels to be set up between remote users and a local secure network. RedFox can encrypt the data packets using 256 bit AES - a level that to date has not been cracked.
Even with these levels of security it is critical that management of RedFox can not be compromised to allow other security features to be changed or the network to be maliciously reconfigured. To this end it is possible to disable the web configuration pages and SNMP if necessary. The CLI is secured using SSH (Secure Shell Protocol) so it is encrypted between the management station and switch.
