Firewalls.Guard your personal information from cyber criminals. Use firewalls.
Every Internet-connected computer is vulnerable to automated attack tools seeking ways to break into and take over your system. Attackers may crash your system, spawn new attacks, or even steal passwords and credit card information.
Firewalls provide virtual barriers that filter out potentially dangerous connection attempts to your device. Unit firewalls (firewalls designed to help protect multiple computers in a university department or a home or apartment complex network) and properly configured personal firewalls (firewalls you can install on your personal computer) can each provide effective security to suit various needs. For home use, personal firewalls are often free.
