6.3 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.
