There are a lot of ways to monitor and analyze the network traffic and protect it from Internet intrusions. Organizations commonly use a firewall for network protection. Although firewall logs often provide a huge information regarding intrusion attempts, sometimes might be of too much data to sort through when there is a problem one cannot resolve it quickly. Some organizations also use Intrusion Detection Systems (IDS) on border routers to analyze incoming traffic for patterns that indicate specific problems. But firewall or intrusion detection system is used primarily on borders with the Internet, rather than on internal networks. This is one of reason why Cisco's NetFlow came to the rescue.
