Firewall Protection

The firewall protects the computers against unauthorized access from the
Internet as well as against attacks originating from inside the local-area
network. It provides protection against information theft as unauthorized
access attempts can be prohibited and detected.
Security Profiles
The firewall contains predefined security profiles which have a set
of pre-configured firewall rules. Different security profiles can be
assigned to different users; for example based on the company
security policy, user mobility, location and user experience.
Firewall Rules
You can configure the firewall by creating and editing firewall
rules. Firewall rules are a set of firewall services - Internet traffic
parameters that control which type of traffic is allowed and
denied. One rule can contain multiple services.
Network Services
Network services are described by what protocol and port they
use, for example web browsing uses TCP protocol and the port
number 80.
