6.4.2. Firewall Profiles

The Firewall allows you to define specific security rules based on whether your computer is located

in a domain, is a standalone computer, or even a notebook. Each of these options requires a

different level of protection, and the levels are covered by the respective profiles. In short, a Firewall

profile is a specific configuration of the Firewall component, and you can use a number of such

predefined configurations.

Available profiles

Allow all - a Firewall system profile that has been pre-set by the manufacturer and is

always present. When this profile is activated, all network communication is allowed and no

safety policy rules are applied, as if the Firewall protection was switched off (i.e. all

applications are allowed but packets are still being checked - to completely disable any

filtering you need to disable Firewall). This system profile cannot be duplicated, deleted,

and its settings cannot be modified.

Block all - a Firewall system profile that has been pre-set by the manufacturer and is

always present. When this profile is activated, all network communication is blocked, and

the computer is neither accessible from external networks, nor can communicate outside.

This system profile cannot be duplicated, deleted, and its settings cannot be modified.

Custom profiles - the custom profiles enable you to take advantage of automatic profile

switching which can be especially useful if you connect to various networks frequently (e.g.

with a notebook). Custom profiles are generated automatically after AVG Internet Security

2012 installation, and covering any individual needs for Firewall policy rules. The following

custom profiles are available:

o Directly connected to the Internet – suitable for common desktop home computers

or notebooks connected directly to the Internet, without any extra protection. This

option is also recommended when you connect your notebook to various unknown

and probably unsecured networks (e.g. in an Internet cafe, hotel room, etc.).The

strictest Firewall policy rules of this profile ensure that such a computer is

adequately protected.

o Computer within domain – suitable for computers in a local network, typically at

school or work. It is assumed that the network is professionally administered and

protected by some additional measures, so the security level can be lower than in

the above-mentioned cases, allowing access to shared folders, disk units etc.

o Small home or office network – suitable for computers in a small network,

typically at home or in a small business. Usually, this kind of network has no

"central" administrator, and only consists of several computers connected together,

often sharing a printer, scanner or similar device, which the Firewall rules must

reflect.
