Network Security Firewall is a technology that is used to protect a computer network from unauthorized access, misuse, and attacks. Firewalls can be implemented in different forms, including hardware-based firewalls, software-based firewalls, and cloud-based firewalls. The main purpose of a firewall is to ensure the confidentiality, integrity, and availability of the network and its resources. Firewalls can filter traffic based on predefined rules and inspect and analyze network traffic.
Network Security Firewall can also include other security features such as virtual private network (VPN) support, intrusion detection and prevention (IDP), and application-level filtering.
