In the Trusted Zone or the Internet Zone section of the Zone Security pane, click View Zone options to expand the list of security options.
Zone security allows you to grant Trusted Zone locations a level of access that differs from Internet Zone locations. (More on Zones.) The access you can manage for each Zone includes which ports are open and more.
To follow are the different security controls that can be applied to a Zone. After each description is the tab name of where the settings reside.
For the preset security levels, the following settings are fixed. For the Custom level, you can change these settings.
Control which standard ports are open to incoming or outgoing traffic. (Defined Ports tab)
For additional ports that you specify, you can determine which ones are open to incoming or outgoing traffic. (Custom level security only - Custom Ports tab)
See a list of all the known attacks that are blocked. (Attacks tab)
When enabled, control the program access based on its IntelliDefense classification. (IntelliDefense tab)
Establish default program permissions. (General tab)
Control broadcast/multicast programs. (General tab)
Control IGMP packets. (General tab)
Control whether the Zone locks when your PC is idle. (General tab)
The preset security levels (Low, Medium, and High) have fixed settings, while the Custom level lets you designate your own settings. You can also block all access or allow all access for a Zone.
The default security is as follows:
Internet Zone default is the preset security level Medium:
Trusted Zone default is the preset security level Low:
To make changes, go to the Zone section that you want to update (Internet Zone or Trusted Zone) and click View Zone options to expand the list of security options.
The options that display let you set the security for the Zone. You can:
Select a preset security level - Low, Medium, or High
