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.

Broadcast/Multicast

Broadcast/Multicast controls the broadcast of messages over a network.

Note: Other settings in iolo Personal Firewall control one-to-one communications, but these communications use a one-to-many format.

Idle Lock

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.

 

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:

IGMP

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.)
