19. Firewall

The Firewall protects your computer from inbound and outbound unauthorized

connection attempts, both on local networks and on the Internet. It is quite similar

to a guard at your gate - it keeps track of connection attempts and decides which

to allow and which to block.

The Bitdefender firewall uses a set of rules to filter data transmitted to and from

your system. The rules are grouped into 3 categories:

General Rules

Rules that determine the protocols over which communication is allowed.

A default set of rules that provides an optimal protection is used. You can edit

the rules by allowing or denying connections over certain protocols.

Application Rules

Rules that determine how each application can access network resources and

the Internet.

Under normal conditions, Bitdefender automatically creates a rule whenever

an application tries to access the Internet. You can also manually add or edit

rules for applications.

Adapter Rules

Rules that determine whether your computer can communicate with other

computers connected to the same network.

You must create rules to specifically allow or deny traffic between your computer

and other computers.

If your computer is running Windows Vista, Windows 7 or Windows 8, Bitdefender

automatically assigns a network type to every network connection it detects.

Depending on the network type, the firewall protection is set to the appropriate

level for each connection.

To find out more about the firewall settings for each network type and how you can

edit the network settings, please refer to “Managing connection settings” (p. 110).

Additional protection is provided by the Intrusion Detection System (IDS). IDS

monitors the network and system activities for malicious activities or policy violations.

It can detect and block attempts to change critical system files, Bitdefender files or

registry entries, the installation of malware drivers and attacks performed by code

injection (DLL injection).

Bitdefender is configured by default to take recommended actions for your protection

automatically, without bothering you. If you want to be informed and decide on the

best action when an application requests Internet access or exhibits suspicious

behavior, you must turn on Paranoid Mode.
