Firewalls Network Security
Firewalls network security refers to the technology and practices used to protect a computer network from unauthorized access or attacks. Firewalls act as a barrier between a trusted internal network and untrusted external networks, such as the internet, by monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. They help prevent unauthorized users or malicious software from accessing or compromising the network, ensuring data confidentiality, integrity, and availability. Firewalls can be implemented as hardware devices, software programs, or a combination of both, and are essential components of a comprehensive network security strategy.
