With cyberattacks proliferating worldwide, a Japanese contest for "white hat" hackers supported by organizations including the communications ministry and National Police Agency is gearing up for the final round this weekend.

The Security Contest, dubbed Seccon, provides an opportunity for those aspiring to become white hat, or "ethical hackers," to test their skills and link up with businesses seeking computer experts who can help prevent black hat hackers from infiltrating their systems and stealing or destroying data.

The nation's largest ethical-hacking contest was started in 2012 by the Japan Network Security Association, a nonprofit organization founded to improve the security of computer systems through education, research and information dissemination.
