A firewall is a security system that can be implemented as both software and hardware, designed to monitor and control incoming and outgoing internet traffic. Its purpose is to prevent unauthorized access to or from a private network, while allowing legitimate communication to pass. Deleting viruses from attachments is a function of an antivirus software, which is different from a firewall. The concept of firewall is used in developing security policies, but it is not itself a policy.
