According to what ZDNet reported last January 10th, many of the most important crypto exchanges in South Korea have passed the audit carried out by the Korean government with regard to security policies and it has therefore been verified that these crypto exchanges are hardly exposed to risks of hacker attacks.
Among the crypto exchanges to pass the security policy audit, there are Bithumb, Coinone and Korbit. In total, the South Korean government had assessed 21 exchanges, but only 7 met all 85 requirements.
The 85 requirements included network security, account security, database access control, incident response, backup management, and more.
This security policy audit was carried out by the Ministry of Science, Technology and Information and the Korean Internet Development Agency (KISA) between September and December 2018.
At the moment it is not yet clear whether the 14 exchanges that failed the security audit will be closed or not.
