Overview of Zone Security Options
Overview of Custom Level Security
The General tab has various firewall controls that you can apply to the specific Zone. To follow is a list of each control, with its available settings and a description of its purpose.
Note: If you're in View mode and want to make changes, go back to the desired Zone in the Zone Security pane and click Edit Settings in the Custom column.
All controls are described below: Default Program Permissions, Broadcast/Multicast, Idle Lock, and IGMP.
A default program permission provides a default, or "fall-back", position so that the firewall knows how to handle a program when other firewall controls are not in place. These permissions apply if:
The Do not show prompts - automatically use default program permissions feature is turned on; OR
You do respond to a prompt within the time period specified in the Show prompts - only use default program permissions after [X] seconds option (default is 15 seconds).
To enter your settings:
For Incoming, select Allow to allow incoming communication; select Block to block incoming communication. You must select one.
For Outgoing, select Allow to allow outgoing communication; select Block to block outgoing communication. You must select one.
Read more about program controls.
Broadcast/Multicast controls the broadcast of messages over a network.
Select the Incoming check box to allow incoming communication; clear the check box to block communication.
Select the Outgoing check box to allow outgoing communication; clear the check to box block communication.
Note: Other settings in iolo Personal Firewall control one-to-one communications, but these communications use a one-to-many format.
Idle Lock controls whether all traffic in a Zone is blocked when your PC has been idle.
Idle Lock is enabled by selecting the Enable check box; clear the check box to disable it.
Enabled. The firewall locks the Zone after the PC has been idle (meaning, you have not moved the mouse/pointing device or used the keyboard) for more than the specified period of time.
A locked Zone does not allow any traffic in or out (unless the communication is by a program whose program policy has the "Bypass locked zone" option enabled for the Zone).
The default period of time after which a Zone will lock is 30 minutes. In the Lock after field, you can change the value by typing in a number or clicking on the up and down arrows.
Notes:
Any use of the keyboard or mouse/pointing device immediately unlocks a locked Zone.
When one or both Zones are locked, the Firewall tray icon changes to yellow.
Disabled. The firewall does not lock the Zone after the PC has been idle. The time shown in the Lock after field is not applicable.
IGMP controls the whether IGMP packets are allowed to pass through the firewall.
IGMP access does not pose a significant threat, but some attacks can cause a computer to crash by sending malformed IGMP packets. (Older versions of Windows 95 and 98 are most susceptible.)
Select the Incoming check box to allow incoming packets; clear the check box to block incoming packets.
Select the Outgoing check box to allow outgoing packets; clear the check to box block outgoing packets.
