NAT Security

Definitions

1. The security implications and controls associated with network address translation, including how internal addresses are hidden, how sessions are tracked, and what exposure still exists through translated services. NAT can reduce casual visibility of internal hosts, but it is not a substitute for firewalling or sound access control.

   In plain English: The security effects and limits of using network address translation.

   Example: "The team had overestimated NAT security and forgotten that the translated admin port was still fully reachable from the internet."
