What is the role of firewalls in protecting against malware and other malicious threats?

The role of firewalls in protecting against malware and other malicious threats is to act as a barrier between a trusted internal network and an untrusted external network, such as the internet. Firewalls monitor and control incoming and outgoing network traffic based on predetermined security rules. They inspect the data packets and block any suspicious or unauthorized traffic, preventing malware and other malicious threats from entering the network. Firewalls also help in detecting and blocking unauthorized access attempts, providing an additional layer of security to the network.
