What is firewalled?

Firewalled is a term used to describe a computer or network system that is protected by a firewall. A firewall is a security device or software application that monitors and controls incoming and outgoing network traffic based on predetermined security rules. By using a firewall, a network administrator can restrict access to unauthorized users or applications and protect the network from outside threats.

Firewalls may be hardware or software-based and can be configured to filter traffic based on specific criteria such as IP address, protocols, ports, and applications. They can also be configured to allow or block traffic based on users, time of day or location. Firewalls can be set up to protect specific devices or entire networks and can be customized to meet specific security requirements.

An organization may use a firewall to protect its internal network from external threats such as hackers, viruses, and malware. Firewalls can also be used to restrict access to specific websites or applications and to monitor employee internet usage. Firewalls play a critical role in maintaining the security and integrity of computer networks and are essential to protecting sensitive data and preventing data breaches.
