- Describe the different types of firewall, the network layer they operate in and where they are best suited for deployment.
- Identify different firewall solutions from different vendors and differentiate on factors like functionality and cost.
- Apply knowledge of regulations and best practice to develop strategy for firewall deployment.
- Describe the best location to deploy firewalls in a number of different scenarios.
- Describe the different types of interface available and how failover and load balancing can be achieved.
- Describe the different methods of firewall implementation at a network level.
- Identify the key elements of firewall configuration including: rules, NTP and logging.
- Apply knowledge of Internet threats to implement basic protection rules.
- Understand when deploying a Unix/Linux based firewall is appropriate.
- Describe the different types of Firewall solutions available on the platform.

Course Overview
Early at the inception of the Internet, attacks started to occur with an increased frequency. This lead to the development of tools to prevent unwanted communications according to a defined security policy. Firewalls now play a key part of any modern day network infrastructure and the concept has extended from a System Administration term into everyday vocabulary. The aim of this course is to provide participants with practical experiences of implementing firewall systems using various platforms, knowledge of the best places to implement firewalls and to reinforce the technical knowledge required to manage firewalls.
Topics Covered
- Introduction to firewalls
- Technology underpinning firewall operation
- Location of firewalls on the campus LAN
- Unix/Linux firewalls and Hardware appliances
- Host Based firewalls
- Practical firewall implementations
- Future technologies
Benefits
This course provides a sound background behind the theory of firewalls then provides a practical guide to the implementing and configuration of various types of firewalls at an organisation.
Who should attend?
This course will be of interest to staff working at JANET connected organisation with responsibility for the management of firewalls of the security of networks. The course requires no previous experience in Firewalls, but assumes a degree of familiarity with basic networking concepts. Experience with using a computer and a standard web browser is required. Some knowledge of preventive security would also be an advantage so delegates might find attending our ‘Managing IT Security’ course prior to registering for this course an advantage.
Timetable/On the Day
The course timetable will be adjusted on the day to allow discussion of areas of particular interest to the audience. The course will therefore run from 10am to 4.30pm. Registration will take place from 09:45 – 10:00.
All our courses are designed to provide a balance between practical activities and information dissemination as we believe people learn when they are engaged within the instructional process. This course includes participant involvement through hands-on activities, discussion, group work and simulations created specifically for the course. All delegates will receive a workbook specifically written for the course.
