A firewall can be a piece of software or a piece of hardware, such as a router, that prevents unauthorised access to or from a private network. The most secure firewall configuration standards will include both:
- Firewall software – this is a program that is installed on a computer and it regulates traffic through applications and port numbers
- Firewall hardware – this is a physical piece of equipment that sits between your network and the gateway to the internet
In order to review your firewall configuration, you are best to employ a cybersecurity company that can conduct a security audit health check. A firewall configuration review will ensure that your business follows the best practices.
It is essential to review your firewall because improperly configured firewalls can have rules that conflict with each other. If this conflict exists, then parts of your network can slow down. On other parts of your network, the firewall could fail, leaving it exposed to cyber attacks and hackers.
A cybersecurity company can check your firewall configuration to identify any weaknesses or unnecessary exposure. They can make firewall configuration recommendations that will help to improve your cybersecurity. They will verify that the rules match the business’s policies and requirements, identify firewall rules that can be optimised or removed, and check the firewall operating system version for known vulnerabilities.
A firewall configuration is the set of rules that are followed to permit or deny packets of data in or out of the network or computer system The configuration of firewalls allow firewall filters to be added or removed, to cater to the security and operational needs of a company or organisation.
Firewall filters and rules can be configured to block packets of information for different reasons. They could, for example, block packets that contain a certain word or phrase, such as x-rated.
