You will probably spend a lot of time configuring security Usually these zones are not domain zones or are not otherwise part of an Active Directory Domain Services (AD DS) infrastructure. Thats because with a VLAN, all three networks would be This is especially true if Documentation is also extremely important in any environment. sensitive information on the internal network. Although the most common is to use a local IP, sometimes it can also be done using the MAC address. It ensures the firewall does not affect gaming performance, and it is likely to contain less sensitive data than a laptop or PC. Without it, there is no way to know a system has gone down until users start complaining. internal computer, with no exposure to the Internet. In general, any company that has sensitive information sitting on a company server, and that needs to provide public access to the internet, can use a DMZ. Cloud technologies have largely removed the need for many organizations to have in-house web servers. Monitoring software often uses ICMP and/or SNMP to poll devices The DMZ is generally used to locate servers that need to be accessible from the outside, such as e-mail, web and DNS servers. The DMZ isolates these resources so, if they are compromised, the attack is unlikely to cause exposure, damage or loss. NAT has a prominent network addressing method. She formerly edited the Brainbuzz A+ Hardware News and currently edits Sunbelt Software?s WinXP News (www.winxpnews.com) and Element K's Inside Windows Server Security journal.
