Personal protection act violation
- On July 23, 2021, ACMS records were exposed after an NCRC employee gave an external contractor login credentials without proper approval, allowing outside access with no tracking of what data was viewed or copied.
- From an NCRC employee : “I opened access via email so that their [the external company’s] IP could connect to our agency’s server. There were no established procedures. I’m ashamed.”
- This may violate Korea’s Personal Information Protection Act (i.e. no access limits, no logs, no secure handling).
