 Firewalls |
| Definition: |
- Firewalls control the traffic through the network by checking for valid identification. A firewall system blocks, redirects, monitors or permits network connections between two networks, a public or unsecured network and a secure network. It can be a special purpose device that physically sits between the two networks or it can be a software package installed on an individual host to accomplish similar tasks for that host.
- Firewalls can be used proactively, aligned with the defined policies requirements. In this mode it is generally more secure to disallow everything and then only permit the type of traffic that an organization explicitly intends to pass through the firewall. The purpose of a firewall is to prevent unauthorised access to network data.
