The Department of Information Security requests specialized IT and information security units of ministries, branches, and localities; State-owned corporations and groups; Financial organizations, State-owned commercial banks; Social Policy Banks, Vietnam Development Bank, Vietnam Cooperatives; and enterprises operating in the postal and e-commerce sectors to review and strengthen solutions to ensure network information security for information systems. In particular, prioritizing monitoring and early warning solutions.

From now until April 15, units need to check and evaluate the information security assurance for information systems under their management, especially information systems that store and process personal information and personal data. In case of detecting risks, vulnerabilities and weaknesses in the system, the unit needs to immediately implement remedial measures.

Agencies, organizations, and businesses need to periodically hunt for threats in the system to promptly detect signs of intrusion. For systems that have detected serious security vulnerabilities, after fixing the vulnerability, the unit needs to immediately conduct threat hunting to determine the possibility of previous intrusion.

Check and update information security patches for important systems according to warnings from the Department of Information Security and related agencies and organizations; periodically check, evaluate and review to promptly detect information security vulnerabilities and existing weaknesses in the system. At the same time, regularly and continuously use digital platforms developed and provided by the Ministry of Information and Communications to support management and enforcement to ensure information security.
