In the world of computer firewall protection refer to a network device which blocks certain kinds of network traffic forming a barrier between a trusted and non-trusted network. Network Firewall Security analogous to a physical firewall in the sense that firewall security attempts to block the spread of computer attacks.

Firewalls use the rules to examine network pockets as they pass through particular locations on a network. If a network does not break any firewall’s rule then it will allow the network to reach its destination. If a network breaks a firewall rule then the firewall will block from sending traffic to the network.

These logs can use to help to determine network conditions including the areas of the network are busiest and which network applications consume more data.

Enforcing Policy

Many networks have policies regarding which users can access data like in a school; they would easily prevent all computers from accessing adult content. On the other hand, a home user can limit the amount of time to use internet. Firewalls allow users to actively enforce these policies by creating specific rules.
