Just as you would if you want to protect your home with security cameras and motion sensors, strong locks on the doors and windows, and a guard dog who barks stridently whenever someone approaches, security software uses multiple means for protection, including a firewall that protects against unauthorized access, and from the wrong data getting in or out of your computer. Security software includes several more key technological components that work together to protect your devices in different ways, such as antivirus technology that works to help protect your information at the file level.

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. Likewise, the role of IPS in network-based protection is to carefully examine the traffic that the Smart Firewall has allowed to enter in. 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. Similarly, the Smart Firewall allows permitted traffic into a network and blocks unpermitted traffic from entering. The first security check at an airport checks passengers’ identification and tickets, only allowing permitted passengers to pass through. You could compare the jobs of the Smart Firewall and IPS in network security to the jobs of different security checks at an airport. Each has a different job, but they work together toward the same goal of detecting and blocking malware and intrusions at the network level. In Norton technology, the Smart Firewall and IPS work together to detect malware and intrusions from network traffic.
