A firewall is software or hardware that acts as a barrier between your computer or network and the internet, blocking unauthorized access to your system while allowing legitimate traffic to pass through. This is the most effective protection against intruders entering from a network connection. Anti-virus programs help protect against malware, but they aren't designed to prevent unauthorized access to your system. Network monitors can also be useful for detecting suspicious activity, but they aren't a replacement for a firewall. Passports are irrelevant for computer security.
