An article in the UK-based Independent provides some interesting background on South Korea's efforts to defend against the cyber-warfare capabilities of North Korea's military-trained hackers. The article notes that "To build its defences, President Park Geun-hye’s government has enlisted 120 of the country’s most talented young programmers, offering full scholarships in return for seven years of military service. The college programme is part of a broader plan. The government is doubling the size of its cyber command to 1,000 people and raised spending on information security by almost 50 per cent to 250bn South Korean won (£144m) between 2009 and 2015."
The article goes on to note how South Korea is playing catch-up to the North in the training of cyber warriors, having suffered large economic losses in a 2013 attack on banks and broadcasters that was traced to North Korea.
