Understanding Firewall Security Devices
A firewall is a hardware or software device designed to protect the perimeter of your network. Essentially, it creates a barrier between your network and the Internet. By intercepting each data packet (block of data) being sent to or from your computer or network, it is able to use customisable rules to determine whether the data is safe or represents a potential threat. In the latter case, the firewall security device immediately blocks that data from entering. This makes it very hard for intruders to gain access.
Firewalls security devices fall into four broad categories: packet filters, circuit level gateways, application level gateways and stateful multilayer inspection firewalls. Each works at protecting a different layer, providing different levels of protection and functionality. It is important to select the right level of security to meet your business needs.
A technology commonly incorporated with firewalls is the Virtual Private Network (VPN), which enables secure and authorised Internet-based connections between offices at different locations, and remote workers and the business network.
Business benefits of firewall security solutions
An effective firewall security solution can protect your business computers or network and valuable data from a wide range of attacks including:
Denial of Service attacks, which can deprive you of access to network resources and destroy files
eaves dropping, where hackers capture sensitive information as it’s typed at a keyboard
spoofing, where hackers disguise themselves as a trusted computer.
In a number of cases, internet firewall solutions incorporate additional internte security features such as anti-virus protection, spam filter and internet filtering.
Note: It is essential to select the right firewall solution to meet your business needs, based on criteria such as size of network, expected traffic, number of remote users, level of protection required,level of encryption and more.
