DMZ

DMZ or Demilitarized Zone refers to an area or zone in between any two countries, where there is no active military presence or activity. The term DMZ is primarily used to refer to the area separating North and South Korea, one of the world's most heavily armed boundaries.

Typically, DMZ areas are created when countries are at war or in a conflict, and a temporary cease-fire agreement has been signed.

DMZ serves as a buffer zone, preventing any violent conflict or hostile activity between two countries. It also enables communication between two countries and helps to maintain the stability of the region.

The creation of DMZ in between North and South Korea has both political and economic impacts on both countries. North Korea's isolation from the rest of the world has limited its economic growth, making it one of the world's poorest countries. A potential economic agreement between North and South Korea, facilitated by the DMZ, would benefit both countries and potentially provide a breakthrough in alleviating tensions on the Korean Peninsula.

Advanced technologies, such as cyber-attacks, have the potential to render traditional DMZ measures ineffective. Thus, this has prompted the development of DMZs for cyber security purposes, which can help to limit unauthorized access to a secure network. In this case, a DMZ serves as a section between the internet and the company's internal network, where only authorized traffic is allowed.
