Firewall Example:

A firewall is a computer system that protects networks and computers from unauthorized access. A firewall blocks incoming and outgoing network traffic and allows only authorized traffic to pass through.

Firewalls are used in businesses, schools, and homes to protect networks and computers from viruses, spyware, and other malware.

A firewall can also protect against unauthorized access to a computer by blocking access to the computer’s network resources. For example, a firewall can block access to the computer’s file system, ports, and services.

A firewall can protect a computer from attacks by unauthorized users, and it can also protect the computer from attacks by authorized users. For example, a firewall can protect a computer from attacks by users who are not authorized to access the computer’s network resources.

A firewall can also protect the computer from attacks by users who are authorized to access the computer’s network resources but who are using malicious software. For example, a firewall can protect a computer from attacks by users who are authorized to access the computer’s network resources but who are using worms or Trojan horses.
