Understanding hardware firewalls
What is a hardware firewall?
A hardware firewall is a network security device that protects a computer network by monitoring and filtering incoming and outgoing network traffic. It acts as a barrier between an internal network and the internet, effectively controlling and regulating the flow of data packets.
How does a hardware firewall work?
Hardware firewalls operate at the network level of the OSI model, examining packets of data and determining whether to allow or block them based on pre-configured security rules. These rules can be set to filter traffic based on various criteria such as IP addresses, ports, protocols, and specific application traffic.
Importance of hardware firewalls
Protection against external threats
A hardware firewall plays a crucial role in protecting small businesses from external threats such as hackers, malicious software, and cybercriminals. It acts as the first line of defense, blocking unauthorized access attempts and preventing malicious traffic from entering the network.
