The Korea Information Security Technology Research Institute Corp. (KISTRI) has demonstrated a new U.S.-developed technology that blocks hacking by building a so-called "black hole" firewall.
 
KISTRI and a cyber-security academy demonstrated the technology, developed by Cyber Advanced Technology, in Seoul on Thursday.
 
The new tool creates a wall that disables the traditional TCP/IP communication language of the Internet.
 
The technology locks hackers in a so-called "black hole" so that they cannot locate information even if they succeed in entering a network.
