Firewall Design – How does it Work?

Designing a firewall involves the following five steps:
1. Identifying your organisational security needs. This is achieved through identifying the security requirements, assessing your security stance and then working with this information to identify your security requirements.
2. Outline a complete security policy that involves network resources, access policies, and authorisation controls. This makes it possible for the firewall to address all security needs and expectations.

3. Defining and configuring the firewall is made easy by identifying resources, applications, and services that will be protected from any threats from external entities and insider attacks.

4. Identify acceptable communications through an acceptable use policy that defines the different network activities that are permitted or not permitted on the LAN and the internet web services.

5. Firewall design is made around identifying enforcement points. Firewalls are implemented at the edge of all networks and are positioned between private LAN and public networks.


To enhance protection a profile is developed that will give an indicator of normal network traffic patterns. Putting a baseline in place makes it possible to identify unusual behaviour, enabling you to put rules in place to protect against attacks.
