On September 15, , during the Korean War , U. Marines force made a surprise amphibious landing at the strategic port of Inchon, on the west coast of Korea, about miles south of the 38th parallel and 25 miles from Seoul. The location had been criticized as too North Korea is a country with a population of some 25 million people, located on the northern half of the Korean Peninsula between the East Sea Sea of Japan and the Yellow Sea. Much of the fighting took place in what is now northeastern China.
The Russo-Japanese War was also a naval conflict, with ships exchanging fire in the The division of Korea is a legacy of the Cold War. Japan annexed the Korean peninsula in , and the country spent the next 35 years under Japanese military rule. North and South Korea have been divided for more than 70 years, ever since the Korean Peninsula became an unexpected casualty of the escalating Cold War between two rival superpowers: the Soviet Union and the United States.
A Unified Korea For centuries before the division, the For nearly seven decades, the Kim family dynasty has warned the North Korean people that the United States is a murderous superpower bent upon their annihilation—and their only chance of survival is readiness for an American attack. This policy of paranoia without end has driven At this eastern end of the DMZ in Goseong, government officials are busy constructing a massive observatory tower scheduled to open this summer, to replace the small building built by the South Korean army in from which visitors currently view the last section of border fence dividing the two nations.
Enterprising entrepreneurs also sell jewelry, as well as liquor, stamps and souvenirs from North Korea. Guests stayed at a resort, managed by an arm of the South Korean conglomerate Hyundai, on the North Korean side of the border. In , however, the program of good will was terminated when a North Korean soldier shot a South Korean visitor at the resort when she wandered into a restricted part of the hotel.
The road leading straight into North Korea still remains, however, in the event that tensions between the countries improve again. Incidents like that one keep South Korean soldiers on the lookout for any potential aggression by their Northern counterparts, including possible attempts to cross over the DMZ. In the decades since the DMZ was established, South Korean forces have uncovered numerous attempts by North Koreans to violate the terms of the agreement and infiltrate the South with the intent of breaking the cease fire.
So far, four tunnels extending from North Korea into South Korea were discovered the most recent in and capable of transferring up to an estimated 30, troops an hour. A DMZ provides an extra layer of security to an internal network. It restricts access to sensitive data, resources, and servers by placing a buffer between external users and a private network. Other benefits include access control, preventing attackers from carrying out reconnaissance of potential targets, and protecting organizations from being attacked through IP spoofing.
A DMZ can be used on a router in a home network. Some home routers also have a DMZ host feature that allocates a device to operate outside the firewall and act as the DMZ. All other devices sit inside the firewall within the home network. A gaming console is often a good option to use as a DMZ host. It ensures the firewall does not affect gaming performance, and it is likely to contain less sensitive data than a laptop or PC. Skip to content Skip to navigation Skip to footer.
What is a DMZ Network? Benefits of Using a DMZ. As a result, the DMZ also offers additional security benefits, such as: Enabling access control: Businesses can provide users with access to services outside the perimeters of their network through the public internet. The DMZ enables access to these services while implementing network segmentation to make it more difficult for an unauthorized user to reach the private network.
A DMZ may also include a proxy server, which centralizes internal traffic flow and simplifies the monitoring and recording of that traffic. Preventing network reconnaissance: By providing a buffer between the internet and a private network, a DMZ prevents attackers from performing the reconnaissance work they carry out the search for potential targets.
Servers within the DMZ are exposed publicly but are offered another layer of security by a firewall that prevents an attacker from seeing inside the internal network.
Even if a DMZ system gets compromised, the internal firewall separates the private network from the DMZ to keep it secure and make external reconnaissance difficult. Blocking Internet Protocol IP spoofing: Attackers attempt to find ways to gain access to systems by spoofing an IP address and impersonating an approved device signed in to a network.
A DMZ can discover and stall such spoofing attempts as another service verifies the legitimacy of the IP address. The DMZ also provides network segmentation to create a space for traffic to be organized and public services to be accessed away from the internal private network.
DMZ Design and Architecture. Single firewall: A DMZ with a single-firewall design requires three or more network interfaces. The first is the external network, which connects the public internet connection to the firewall.
