A DMZ is a network that exists between an organization’s internal network and the Internet. The purpose of a DMZ is to allow organizations to expose select systems to the Internet while keeping other systems on the internal network safe from exposure.

Key Points

  • A DMZ is a network security measure that creates a barrier between an organization’s internal network and the Internet.
  • A DMZ can be used to protect sensitive information from being accessed by unauthorized individuals.
  • A DMZ can also be used to isolate systems that are more likely to be targeted by attacks.
  • Organizations should carefully consider their needs before implementing a DMZ.
