The security device that is installed between a computer network and the Internet is a firewall.
A firewall acts as a barrier between the internal network of a business and the external network (Internet). It monitors and controls incoming and outgoing network traffic based on predetermined security rules. Firewalls help prevent unauthorized access to or from the network, thereby enhancing data privacy and security.
Firewalls can be either hardware-based or software-based, and they are essential components of network security in businesses to protect against cyber threats and unauthorized access. By filtering network traffic and blocking malicious activities, firewalls play a crucial role in safeguarding sensitive data and ensuring a secure network environment.
