What is the role of firewalls in protecting against ransomware and other forms of malware?

The role of firewalls in protecting against ransomware and other forms of malware is to act as a barrier between an internal network and external networks, filtering and monitoring incoming and outgoing network traffic. Firewalls analyze the data packets and determine whether they should be allowed or blocked based on predefined security rules. By inspecting and blocking potentially malicious traffic, firewalls can prevent ransomware and other malware from entering the network and infecting systems. Additionally, firewalls can also detect and block suspicious outbound traffic, preventing malware from communicating with command and control servers or exfiltrating data.
