50+ Fortinet Firewall MCQ for interview

What is Firewall?
A firewall is a security device or software that monitors and controls incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet, to prevent unauthorized access and protect against malicious activities. Firewalls can be implemented in various forms, including hardware appliances, software applications, or as a combination of both. They inspect data packets as they pass through the network, determining whether to allow or block them based on established security policies. By enforcing access control and filtering network traffic, firewalls help organizations enhance their overall cybersecurity posture and safeguard sensitive information from cyber threats such as hackers, malware, and unauthorized access attempts.
