MAS cyber hygiene notices set baseline cyber controls for Singapore financial institutions by entity type.

What MAS is trying to do
Cyber hygiene requirements establish minimum controls that reduce common cyber risk. They are not a complete cyber security program, but they create enforceable baseline expectations around accounts, patching, security standards, malware protection, perimeter defense, and authentication.
What teams need to do
- Identify the cyber hygiene notice applicable to the institution.
- Map systems and providers supporting regulated operations.
- Maintain evidence for administrative accounts, patching, secure configuration, malware controls,
network defense, and MFA where required.
- Include third-party technology providers where they operate or support relevant systems.
Evidence to maintain
- Notice applicability analysis.
- System and provider inventory.
- Admin account, patch, baseline security, malware, perimeter, and MFA evidence.
- Exceptions, remediation, monitoring, and reporting.
Common gaps
- Cyber hygiene evidence is collected internally but not for managed service providers.
- Exceptions are accepted without owner, due date, and compensating control.
- Notice applicability is not refreshed after license or system changes.
How Halbarad helps
Halbarad helps teams connect providers to cyber hygiene evidence, exceptions, remediation, monitoring signals, and audit trail. It supports evidence collection; it does not replace MAS notice review.
