DMZs are also known as perimeter networks or screened subnetworks. What is Network Virtual Terminal in TELNET. Further, DMZs are proving useful in countering the security risks posed by new technology such as Internet-of-Things (IoT) devices and operational technology (OT) systems, which make production and manufacturing smarter but create a vast threat surface. 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.
