Firewall Routers
Security is one of the most important concerns for any industry that utilizes internet connections for data transmission. Security must be built in every step of the network system’s transit in order to reduce the risk of data theft or sabotage. Software and hardware firewalls can be installed to prevent dangerous pieces of data from reaching devices connected to the network.
Software firewalls are installed on each individual computer on a network and can distinguish between its programs. This makes it easy for the software to allow data to one program while blocking another. It also can filter ongoing data as well as remote responses to outgoing requests. Unfortunately, software firewalls require installation, updating and administration on each individual computer.
A router is a device that manages data packet transmission between networks based on their intended IP addresses and allows multiple devices to use the same internet connection. The process of managing and separating the data packets is a kind of firewall. If unwanted data comes in, the router will identify it as belonging to another computer and discard it. Routers lack the advanced features and options that dedicated hardware firewalls offer.
Firewall routers protect the control networks of industrial facilities while maintaining fast data transmission. They are specifically designed for automation networks. Industrial firewall routers combine an industrial firewall, router, VPN and L2 switching functions into a single device that protects the integrity of remote access and critical devices.
