A firewall absolutely isolates your computer from the Internet using a "wall of code" that inspects each individual "packet" of data as it arrives at either side of the firewall — inbound to or outbound from your computer — to determine whether it should be allowed to pass or be blocked. It's used for protecting Tonmind IP Speaker, IP Intercom, ONVIF Speaker web setting.

Firewalls have the ability to further enhance security by enabling granular control over what types of system functions and processes have access to networking resources. These firewalls can use various types of signatures and host conditions to allow or deny traffic. Although they sound complex, firewalls are relatively easy to install, setup and operate in Tonmind IP PA System.

Most people think that a firewall is a of device that is installed on the network, and it controls the traffic that passes through IP Speaker, PA System.

However, you can have a host-based firewalls. This can be executed on the PA Systems themselves, such as with ICF (Internet Connection Firewall). Basically, the work of both the firewalls is the same: to stop intrusion and provide a strong method of access control policy. In simple definition, firewalls are nothing but a system that safeguards your computer, access control policy enforcement points.

Like anything, the high-speed connection has its own drawbacks. Ironically, the very feature that makes a high-speed connection attractive is also the reason that makes it vulnerable. In a way, connecting to the internet via high-speed connection is like leaving the front door of your house open and unlocked. This is because high-speed Internet connections have the following features:

• A constant IP - Make it easy for an intruder who has discovered your computer on the internet to find you again and again.
• High-Speed Access - Means that the intruder can work much faster when trying to break into your computer.
• Always active connection - means that your computer is vulnerable every time when it is connected to the internet.

Defending yourself with a Personal Firewall

So now you have an idea of how you are vulnerable every time when you are online on a high-speed Internet connection, compared to an ordinary 56Kbps connection. What you now need to know is how you can defend yourself against the threat posed by this type of connection

A Personal firewall is important when

• You surf the internet at home using an 'always on' broadband connection.
• You connect to the internet via a public WiFi network in a park, cafe or airport.
• You run a home network which needs to be kept isolated from the internet.
• You wish to be kept informed when any program on your computer attempts to connect to the internet.
• Most Personal Firewalls are highly configurable so you can easily create security policies to suit your individual needs.
