Firewalls
Firewalls can make your network appear invisible to the Internet, and they can block unauthorized and unwanted users from accessing your files and systems. Hardware and software firewall systems monitor and control the flow of data in and out of computers in both wired and wireless enterprise, business and home networks. They can be set to intercept, analyze and stop a wide range of Internet intruders and hackers.
Firewall Technology
Like VPNs, there are many types and levels of firewall technology. Many firewall solutions are software only; many are powerful hardware and software combinations. Some WiFi gateways and access points provide a built-in firewall capability. But even if they don't, most WiFi gateways include a NAT routing capability that acts like a basic firewall, making the networked computers and their data invisible to simple hacking scans and probes.
