Managing Personal Firewall security types

Part of choosing the security that works best for you is deciding how you want to manage alerts and respond to them. Alerts appear when Personal Firewall detects an intrusion attempt, unwanted network traffic, or suspicious activity from incoming or outgoing Internet connections. By default, the security type is set to Smart Access, which allows known programs to send information to and from your PC.

Set your security type to determine whether Personal Firewall allows programs on your PC to automatically connect to the Internet, and whether to notify you.
