The Smart Firewall monitors the communications between your computer and other computers on the Internet. It also protects your computer from such common security problems as the following:
| Improper connection attempts | Warns you of connection attempts from other computers and of attempts by programs on your computer to connect to other computers |
| Port scan | Cloaks the inactive ports on your computer thereby providing protection against attacks through hacking techniques such as port scanning |
| Intrusions | Monitors the network traffic to or from your computer for suspicious behavior and stops any attack before they threaten your system |
A firewall blocks cybercriminals and other unauthorized traffic, while it allows authorized traffic to pass. The Windows Firewall feature monitors all inbound communications to your computer. However, Windows Firewall does not monitor the outbound communications from your computer to the Internet.
NortonLifeLock recommends that you keep the option turned on to let Norton monitor all inbound and all outbound communications of your computer. The Smart Firewall feature automatically creates program rules for each program that you run. When the option is turned on, Norton retains the Automatic Program Control settings for all programs.
Turning off Smart Firewall reduces your system protection. Always ensure that the Smart Firewall is turned on.
