Overview: What can Internet Shield be Used for?

6.1.1

Global Firewall Security Levels

Internet Shield protects the computers against unauthorized access from
the Internet as well as against attacks originating from inside the LAN. It
provides protection against information theft, because unauthorized
access attempts can be prohibited and detected. It also protects the users
against malicious applications and provides a possibility to control
network usage and prohibit the use of bandwidth consuming applications.
The Firewall component included in the Internet Shield can be used to
restrict traffic based on the protocols used. Application Control is
designed to prevent malicious programs from sending information out of
the computer. It can be used to further restrict the traffic based on the
applications, the IP addresses and the ports used. Intrusion Prevention
System stops the malicious packets aimed at open ports in the host.
Internet Shield contains seven predefined security levels, and each of
them have a set pre-configured Firewall Rules associated with them.
Different security levels can be assigned to different users based on, for
example, company security policy, user mobility, location and user
experience. For detailed explanations of different security levels, see
"Global Firewall Security
The Global Firewall Security levels that exist in the F-Secure Internet
Shield are:

host are met. For more information, see
