Firewall software acts as a gateway. It usually consists of a set of routers between the machine and network. The firewall is of four different types. Application gateway, packet filter gateway, circuit level gateway and proxy server. The most basic firewall is the packet filter firewall. A packet filter firewall filters packets coming into and going out of the machine based on user configuration. If a certain packet does not fit into previously defined user configuration then it is discarded. For example the packet contains some information about the packet. So if the user has blocked a certain port number or IP address all packets coming from that port number or IP address will be discarded. A circuit level firewall does security checkup when the TCP or UDP connection is being set up between host and network. No further checking is done after connection setup. An application level firewall works at the application level. It is used for filtering required by higher level protocols like telnet, FTP, HTTP etc. It is more reliable and efficient than packet filter firewall. Application level gateway helps check mails as well and keeps unwanted or harmful date out of the system by preventing its entry.

A proxy server is kind of a relay server. When you make any request for a website this is sent to the proxy server. The proxy server then relays this request to a main server which in turn looks up the address and sends the corresponding IP to the proxy server. The proxy server then relays back this information to the client who requested the address. A Proxy thus acts as a firewall between machine and network. You can adjust proxy server settings according to your own needs. Thus a firewall works as an antivirus by protecting your machine from getting infected. It is one of the most efficient desktop security mechanisms available for computer security. Apart from providing security a firewall system can also be used to setup drive backup software. It can help filter sensitive data and store it in a backup system which can be retrieved whenever necessary. Depending on your needs you can choose between any of the types of firewalls. For a local network or office internal network packet filter can be ideal. For external networks application gateways and proxy servers are a must.

A firewall provides excellent security and it is flexible enough to be configured according to user requirements and specifications. It keeps out unwanted packets, data and content. So if security is a concern do not forget to install the latest firewall software to keep your computer virus free and fully functional.
