Understanding Firewalls
6-2
Firewalls control access to ports on network-connected computers and devices. With the Mobile Security
firewall, you can control which ports external applications can use to connect to your device. You can
control the ports that applications running on your device can use to connect to external systems. In
addition to controlling access to ports, you can control which IP addresses can connect to your device and
the addresses to which your device can connect.
A firewall boosts security on your network-connected device by preventing unwanted connections initiated
by external systems or applications running on your device. For example, to prevent a hacker from
accessing your device through a particularly vulnerable port, you can block that port.
Ports are typically associated with certain applications and services. See
