Network Security Firewall
A network security firewall is a security system designed to monitor and control incoming and outgoing network traffic based on predetermined security rules. It acts as a barrier between a trusted internal network and untrusted external networks, such as the internet, to protect against unauthorized access and potential cyber threats. Firewalls can be implemented as hardware devices, software programs, or a combination of both, and are essential for safeguarding sensitive data and maintaining the integrity of a network infrastructure.
