Firewalls Questions
The role of firewalls in protecting against data breaches and unauthorized data exfiltration 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 security rules, firewalls help prevent unauthorized access to sensitive data, block malicious traffic, and detect and prevent data exfiltration attempts, thereby enhancing the overall security of the network.
