Hardware Firewalls
Hardware firewalls are physical devices that are designed to protect a network by monitoring and filtering incoming and outgoing traffic. They act as a barrier between a secure internal network and untrusted external networks, such as the internet. Hardware firewalls use a combination of hardware and software to inspect data packets and determine whether they should be allowed to pass through based on predetermined security rules. They are typically placed at the perimeter of a network to provide a first line of defense against cyber threats.
