Network-level protection: Smart Firewall + IPS
In Norton technology, the Smart Firewall and IPS work together to detect malware and intrusions from network traffic. Each has a different job, but they work together toward the same goal of detecting and blocking malware and intrusions at the network level.
You could compare the jobs of the Smart Firewall and IPS in network security to the jobs of different security checks at an airport. The first security check at an airport checks passengers’ identification and tickets, only allowing permitted passengers to pass through. Similarly, the Smart Firewall allows permitted traffic into a network and blocks unpermitted traffic from entering. At the next layer of airport security, security officers and x-ray machines inspect the baggage of authorized passengers who have already passed through the first layer of security. Likewise, the role of IPS in network-based protection is to carefully examine the traffic that the Smart Firewall has allowed to enter in.
Many threats are caught at the network level, and for advanced malware that sneaks past, the other layers of Norton security technology go to work detecting, quarantining and removing threats from your computer.
