There are two main types of firewalls. One is hardware and the other is software. Both protect your computer and network from hackers and from some malevolent software.
Without any firewall anybody with internet access could get into your company network and computer data with only their internet connection and a little knowledge.
What is the Function of a Firewall?
A firewall is a filter. It blocks access to anybody or any software who is not authorized. Routers have a firewall built into their hardware. Settings can be adjusted for additional protection. There are also firewall software programs that add protection in addition to the routers. Because larger networks have multiple routers in place, computer traffic is checked repeatedly for redundant safety.
Another Firewall Feature
Firewalls can also be used to control outgoing internet traffic. That use of firewalls is less widespread. It can prevent access to certain websites or groups of websites that are considered non-business related.
What Do Firewalls Check?
What specifically is checked? Internet service providers have huge lists of unsafe website addresses and domains that are used to block known sources of hacking and malware. The list is always in flux. In addition, there are traits of packets of data that are characteristic to hackers and hacking. Those are found and blocked. They include specific words and combinations of words, port numbers and protocols.
