What are firewalls, and how do they act as a critical line of defense for organizations?
Firewalls are security systems designed to monitor and control incoming and outgoing network traffic based on predetermined security rules. They act as a critical line of defense for organizations by acting as a barrier between trusted internal networks and untrusted external networks (such as the Internet). Firewalls help prevent unauthorized access, malware infections, data breaches, and other cyber threats by filtering network traffic and enforcing security policies. Their role is crucial in protecting sensitive information and ensuring the security and integrity of organizational networks.
