Firewall
Avira FireWall monitors and regulates incoming and outgoing data traffic on your computer
system and protects you from a wide range of attacks and threats from the Internet:
Incoming or outgoing data traffic or listening to ports will be allowed or denied based on
security guidelines. You will receive a desktop notification if Avira FireWall denies network
activity and thus blocks network connections. The following options are available for Avira
FireWall settings:
by setting a security level in the Control Center
You can define a security level in the Control Center. The
low
,
medium
and
high
security levels each contain several complementary security rules based on packet
filters. These security rules are saved as predefined adapter rules in the Configuration
under
FireWall > Adapter rules
by saving actions in the Network event window
When an application first tries to create a network or Internet connection, the
Network
Event
popup window appears. The
Network Event
window allows the user to choose
whether the network activity of the application is allowed or denied. If the
Save Action
for this application
option is enabled, the action is created as an application rule and
is saved in the configuration under
FireWall > Application Rules
. Saving the actions
in the Network event window gives you a set of rules for the network activities of
applications.
Note
For applications from trusted vendors, network access is allowed by default
unless an adapter rule prohibits network access. You have the option of
removing providers from the list of trusted vendors.
by creating adapter and application rules in the Configuration
You can alter predefined adapter rules or create new adapter rules in the
Configuration. The security level of the FireWall is automatically set to the value
User
if
you add or change adapter rules.
Application rules allow you to define monitoring rules specified for applications:
You can use simple application rules to define whether all network activities of a
software application are to be denied or allowed or whether they are to be handled by
means of the
Network Event
popup window.
In the advanced configuration of the
Application rules setting
you can define different
packet filters for an application, which are executed as specified application rules.
