Internet Firewall Software
What is internet firewall software? Well, in computing, an internet firewall is a network security system that both controls and monitors both the incoming and outgoing network traffic. Control access is based on predetermined security rules. What a firewall does is that it builds a barrier between a trusted internal network and an untrusted external network. A good example of an untrusted external network is the internet.
Firewalls
Firewalls are categorized into two parts. These are network firewalls and host-based firewalls. The network firewall acts as a filter that filters the traffic between all networks that run on the hardware.
On the other hand, a host-based firewall runs on the host’s computer. This type of firewall controls the network traffic that goes in and out of the machine. There are different generations of firewalls available today. The different generations are listed below;
- First-generation – packet filter.
- Second generation – stateful filters.
- Third generation – application layer.
These are the different generations of firewalls.
Firewall Proxies
What are proxies? A Proxy server can act as a firewall. This is done when the proxy responds to input packets (connection requests) in the manner an application would while blocking other packets. A proxy server is also a gateway between networks. This gateway is only for specific network applications. This is in the sense that it works as a proxy server on behalf of the user of the network. Proxies make it difficult to temper with an internal system using an external network. This is done so that the misuse of any internal system would not lead to a security breach from the outside network. This is as long as the proxy remains properly configured and intact.
