why we need firewalls?

[alandandrew]

Firewalls are usually seen as a requirement if you are going to attach your network to other networks, especially the Internet. Unfortunately, some network administrators and managers do not understand the strengths a firewall can offer, resulting in poor product choice, deployment, configuration and management. Like any security technology, firewalls are only effective if the implementation is done properly and there is proper maintenance and response to security events.

Additionally, with the proper deployment of firewalls other security strategies are often much easier to integrate, such as VPNs and IDS systems. So what makes firewalls good, and what can you do to ensure they are used properly?
