Question

Quizplus · Accepted Answer

The most common computer security precaution taken by businesses is the installation of firewalls. A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on an organization's previously established security policies. It acts as a barrier between a trusted, secure internal network and an untrusted network such as the Internet. Firewalls can prevent unauthorized access to systems and protect against malicious activities such as viruses and hacking attempts.
