What Is Network Firewall?

A network firewall is a security system designed to protect a private network from malicious or unauthorized access. It is a combination of hardware and software that inspects incoming and outgoing network traffic and blocks any malicious or unauthorized traffic. Firewalls can be used to protect both wired and wireless networks, and can be configured to allow or deny certain types of traffic. Firewalls can also be used to monitor and log network activity, and can be used to detect and prevent malicious activities such as malware, phishing, and other cyber-attacks.
