The State Bank of Vietnam (SBV) has finalised a draft circular on safety and security in providing online services in the banking industry.

Under the draft circular, the online banking system must comply with the Government’s current regulations on ensuring the information system security at Grade 3 or higher.

According to the Law on Cyberinformation Security 2015, classification of information systems by security grade means the determination of information security grades of information systems in an ascending order from 1 to 5.

Grade 3 means that when an information system is sabotaged, it will seriously harm production, public interests and social order and safety or will harm national defence and security.
