About Smart Firewall Advanced Settings

Smart Firewall Advanced Settings let you activate advanced protection features of Smart Firewall. Your options are:

General Rules

Determines how the Smart Firewall controls incoming network traffic and outgoing network traffic

Uncommon Protocols

Determines how the Smart Firewall handles uncommon protocols such as Internet Group Management Protocol (IGMP) and IPv6 Hop-by-Hop Option (HOPOPT)

Firewall Reset

Returns the Smart Firewall to its default state. You can click Reset to ensure that all recommended firewall rules and settings are configured. Norton Internet Security prompts you with a confirmation dialog box when you reset firewall.

If you reset the firewall, you remove any custom rules or settings that you have configured. Resetting the firewall clears the AutoBlocked computers and also changes the Trust Control settings in the Network Security Map.

In Windows XP, Norton Internet Security prompts you to select the trust level of the network after you reset the firewall. The alert appears only if your computer matches the following criteria:

  • You need to set the Automatic File/Printer Sharing Control to Ask Me

  • Your computer must have at least one shared resource or the operating system need to be Windows Media Center edition

  • Your computer must use a private IP address range

  • Your computer must be connected to a secure wireless or wired connection

Stealth Blocked Ports

Ensures that blocked and inactive ports do not respond to connection attempts

Prevents the active ports from responding to connection attempts with incorrect source or destination information.

Stateful Protocol Filter

Automatically allows the Internet traffic that matches the connections that an application opens

Check this option to do the following:

  • Analyze the network traffic that enters your computer.

  • Block the suspicious applications that try to connect to your computer.

Automatic File/Printer Sharing Control

Allows the computers on the network to share resources such as files, folders, and printers (that are locally attached)

Some of the Windows 7 features such as Home Media Experience work only when the trust level of the network to which your computer is connected is set to SHARED or FULL TRUST. When Automatic File/Printer Sharing Control is ON, it sets the trust level of the network to SHARED only if certain other security criteria such as the following match:

  • Your computer must have at least one shared resource or the operating system need to be Windows Media Center edition

  • Your computer must use a private IP address range

  • Your computer must be connected to a secure wireless or wired connection

You can set this option to On or Off state. In windows XP, you can also set this option to Ask Me. In this state, Norton Internet Security prompts you before it classifies a new network to which your computer is connected as Shared or Protected. The prompt appears only when the security criteria for sharing matches.

Automatic Program Control

Automatically configures Internet access settings for the Web-enabled programs that are run for the first time

The Automatic Learn IPv6 NAT Traversal Traffic option is available only when Automatic Program Control is turned on. Norton Internet Security provides this option to control the network traffic that uses Teredo to communicate with your computer. Some of the Windows 7 features such as Remote Media Experience and Remote Assistance work only when Automatic Learn IPv6 NAT Traversal Traffic is on.

When you turn off Automatic Program control, you can turn on Advanced Events Monitoring. You can use the Advanced Events Monitoring options, to configure the Internet access settings for Internet-enabled programs the first time that they run.

When you turn on Advanced Events Monitoring feature, you are prompted with numerous firewall alerts. If you do not want to receive firewall alerts, you can turn on Automatic Program Control.

You can also turn on Silent Mode to suppress the alerts. In this case, the firewall behaves the same as when Automatic Program Control is turned on. Norton Internet Security does not prompt you with any firewall alerts in this state. You cannot configure Advanced Events Monitoring when you turn on Silent Mode.

The Advanced Events Monitoring settings consist of the following categories that provide your computer with advanced protection:

  • Program Component

    This option protects you against the malicious programs that launch Internet-enabled programs.

  • Program Launch

    This option protects you against the malicious programs that attach to safe programs without being detected.

  • Command Line Execution

    This option protects you against the Trojan horses or malicious programs that launch trusted applications in hidden mode through-command line parameters.

  • Code Injection

    This option protects you against the Trojan horses or malicious programs that inject code into an application's process without firewall alerts.

  • Window Messages

    This option protects you against the Trojan horses and other malicious programs that manipulate an application's behavior to connect to the Internet without firewall alerts.

  • Direct Network Access

    This option protects you against the Trojan horses and other malicious programs that bypass network traffic.

    These programs penetrate the Windows TCP/IP layer to send and receive data without triggering firewall alerts.

  • Active Desktop Change

    This option protects you against the malicious programs that use the documented interfaces that the trusted applications provide to transmit data outside the network without triggering firewall alerts.

  • Key Logger Monitor

    This option protects you against the malicious keylogger programs that access personal information of a user on a particular computer by monitoring their keystroke activities.

  • COM Control

    This option protects you against the malicious programs that manipulate an application's behavior by instantiating controlled COM objects.

Turning off Automatic Program Control

Turning on or turning off Silent Mode manually
