Explanation:

A firewall is a software or a hardware device on a network or host that filters the incoming and outgoing traffic to prevent unauthorized access to private networks. A firewall can use various criteria, such as IP addresses, ports, protocols, or application rules, to allow or deny the traffic. A firewall can also perform other functions, such as logging, auditing, encryption, or proxy services. A firewall can be deployed at different levels of a network, such as network perimeter, network segment, or host level12.
