Modern Firewalls and Internet security

Duration:
2 day - workshop

Target group:
Technical people with an interest in networks, firewalls, web servers, security. Knowledge of firewalls is not required, but some knowledge about TCP/IP will be necessary.

Goals:
Inform the participants of common threats and activity in the Internet area, while proposing the idea of how an advanced modern firewall could be configured.

Contents:
Firewalls are but on of the technical guards which today is being used to counter the threats from the Internet. In this workshop the threats and scenarios are covered to teach the participants about strong and weak aspects of a firewall. The idea by using the workshop method is to show examples of attacks and how a firewall can be configured to counter these. The examples are being shown using the OpenBSD packet filter, which in syntax is very similar to IPF - which can be used on many UNIX platforms. Main focus will be the principles and terms used in TCP/IP and can therefore be used immediately for implementing firewalls using any other products later. Remember that a firewall does not protect against everything, but can give good protection for some threats.
