Firewall teh suatu packet em... program kali yah gunanya buat ngeprotect suatu
network. Nih dech ada definisi dari Whatis.com :)
A firewall is a set of related programs, located at a network gateway server, that
protects the resources of a private network from users from other networks. (The term
also implies the security policy that is used with the programs.) An enterprise with
an intranet that allows its workers access to the wider Internet installs a firewall
to prevent outsiders from accessing its own private data resources and for controlling
what outside resources its own users have access to.
Basically, a firewall, working closely with a router program, filters all network
packets to determine whether to forward them toward their destination. A firewall also
includes or works with a proxy server that makes network requests on behalf of
workstation users. A firewall is often installed in a specially designated computer
separate from the rest of the network so that no incoming request can get directly at
private network resources.
There are a number of firewall screening methods. A simple one is to screen requests
to make sure they come from acceptable (previously identified) domain names and IP
addresses. For mobile users, firewalls allow remote access in to the private network
by the use of secure logon procedures and authentication certificates.
A number of companies make firewall products. Features include logging and reporting,
automatic alarms at given thresholds of attack, and a graphical user interface for
controlling the firewall.
Ok?! :)
