Firewalls Questions
The role of firewalls in preventing unauthorized access to sensitive data is to act as a barrier between an internal network and external networks, such as the internet. Firewalls monitor and control incoming and outgoing network traffic based on predetermined security rules. They analyze the data packets and determine whether to allow or block them based on factors such as source, destination, port, and protocol. By enforcing these rules, firewalls help to prevent unauthorized access to sensitive data by blocking malicious or unauthorized network traffic from reaching the internal network.
