 3.Firewall


 4. Classification of firewall
Intranet
 When offices build a computer network in a limited
range, intranet is a network built using standard
technology of Internet.
The good point of the intranet is a cost cut and the
selectivity of function.
Adversely, a bad point is that many people can know
the secret matter.
Subcontractor


The meaning of subcontractor is "Someone who
enters into a subcontract with the primary
contractor.".
Perhaps I think that I show the Internet with this
textbook.
Firewall

    The firewall is a system that prevents it from
invading
 the computer network of the organization from the
outside.
 Or, it is a computer which such a system was built
in.
Classification of firewall

The firewall is classified in detail depending on the
operating protocol hierarchy.
        - Packet filter type
        - Circuit level gateway type
        - Application gateway type
 Packet filter type has three type:Static packet filter,
Dynamic packet filter,and Stateful packet inspection.
