A firewall provides protection from external internet attackers by protecting your computer or network from malicious or unwanted network traffic. Firewalls can also prevent malicious software from accessing a computer or network over the Internet. Firewalls can be configured to block data from specific locations (i.e., computer network addresses), applications, or holes while allowing relevant and required data.
A firewalls filter network traffic within a private network. Analyzes which traffic should be allowed or restricted based on a set of rules. Think of a security program as a security guard on your computer's access point that only allows trusted sources, or IP addresses, to access your network.
