42 Kaspersky Internet Security 7.0
These zones are by default average risk-level zones. You can change
the status of these zones based on how much you trust a certain
subnet, and you can configure rules for packet filtering and applications.
All the zones detected will be displayed in a list. Each of them is shown with a
description, their address and subnet mask, and the degree to which any
network activity will be allowed or blocked by Firewall.
• Internet. This is the default status assigned to the Internet, since when
you are connected to it, your computer is subjected to all potential threat
types. This status is also recommended for networks that are not
protected by any anti-virus programs, firewalls, filters, etc. When you
select this status, the program ensures maximum security while you are
using this zone, specifically:
• blocking any network NetBios activity within the subnet
• blocking rules for applications and packet filtering that allow NetBios
activity within this subnet
Even if you have created a shared folder, the information in it will not be
available to users from subnetworks with this status. Additionally, if this
status is selected for a certain subnetwork, you will not be able to access
files and printers of this subnetwork.
• Local Network. The program assigns this status to the majority of
security zones detected when it analyzes the computer’s network
environment, except the Internet. It is recommended to apply this status
to zones with an average risk factor (for example, corporate LANs). If you
select this status, the program allows:
• any network NetBios activity within the subnet
• rules for applications and packet filtering that allow NetBios activity
within this subnet
Select this status if you want to grant access to certain folders or printers
on your computer, but want to block all other outside activity.
• Trusted. This status is given to networks that you feel are absolutely
safe, so that your computer is not subject to attacks and attempts to gain
access to your data while connected to it. When you are using this type of
network, all network activity is allowed. Even if you have selected
Maximum Protection and have created block rules, they will not function
for remote computers from a trusted network.
You can use Stealth Mode for added security when using networks labeled
Internet. This feature only allows network activity initiated from your computer,
meaning that your computer becomes invisible to its surroundings. This mode
does not affect your computer’s performance on the Internet.
