Firewall is the first line of defence to protect your system from threats,as the system communicates with other system across the Globe there is data being transferred thru and fro,firewall decides as to which requests need to be allowed and malicious contents are blocked and not allowed to send requests to the system.

[manoharparakh]

Firewalls can be an effective means of protecting a local system or network of systems from network-based security threats while at the same time affording access to the outside world via wide area networks and the Internet.

Firewall provides four type of controls:

• Service control: Determines the types of Internet services that can be accessed, inbound(packets which are coming inside the network) or outbound(packets which are going outside the network).

For Example: In many companies services like Gmail and Facebook are not accessible if you use company’s wifi network because firewall is keeping a check on outbound network(This may vary from company to company).

• Direction control: Determines the direction in which particular service requests may be initiated and allowed to flow through the firewall.

• User control: Controls access to a service according to which user is attempting to access it.This feature is typically applied to users inside the firewall perimeter (local users).It may also be applied to incoming traffic from external users.

For Example: Many companies have inbuilt policies of Web content filtering based on the position of an Employee/or a particular department.

Mr X(Manager ) might have access to Quora but a trainee might not have for the same.

• Behavior control: Controls how particular services are used.For example,the firewall may filter e-mail to eliminate spam,or it may enable external access to only a portion of the information on a local Web server.
