Singapore’s digital infrastructure is governed by a robust set of cybersecurity frameworks. For companies working with government agencies or financial institutions, compliance is no longer optional—it’s a critical success factor.
This guide explains three of the most important frameworks:
-
IM8 (The Instruction Manual for ICT&SS Management) – The baseline for all public sector IT systems
-
CCoP Cybersecurity Code of Practice – The mandatory cybersecurity requirements for essential service
-
MAS-TRM – Regulatory guidelines for financial institutions and fintechs
IM8 – (The Instruction Manual for ICT&SS Management) (For Public Sector IT)
IM8, governed by the Smart Nation and Digital Government Group (SNDGG), sets the foundational security and governance policies for all public sector IT systems. It dictates how systems should be architected, managed, and secured.
Key Focus Areas:
-
Access control and account management
-
Network segregation
-
Logging and monitoring
-
Data classification and protection
-
Change and patch management
Many government agencies derive their audit frameworks directly from IM8 policies.
Cybersecurity Code of Practice (CCoP)
The Cybersecurity Code of Practice (CCoP) is issued by the Cyber Security Agency of Singapore (CSA) and applies to Critical Information Infrastructure (CII) for essential services such as energy, transport, water, healthcare, and defence-related systems.
CCoP defines the minimum cybersecurity requirements that CII systems must meet to ensure cyber resilience, operational continuity, and national security.
Many CII systems are:
-
On-premise deployments
-
Operational Technology (OT) systems
-
Air-gapped or highly restricted environments
Key Minimum Requirements:
- Asset Management
-
Secure System Architecture
-
Access Control & Authentication
-
System Hardening & Secure Configuration
-
Logging & Monitoring
-
Malware Protection & Removable Media Controls
-
Vulnerability Assessment & Penetration Testing (VAPT)
-
Backup & Recovery
For a more detailed breakdown, refer to our blog on CII Cybersecurity Code of Practice for OT & Air-Gapped Environments.
SSAT / SSCT – Cybersecurity Assessment to Validate CCoP Compliance
The System Security Compliance / Acceptance Test (SSAT) is the formal assessment and audit used to validate compliance with the CCoP requirements.
SSAT is typically required before system acceptance, network connection, or go-live for CII and government-related projects involving IP-enabled systems.
In practice, CCoP defines the “what”, while SSAT validates the “how well” the cybersecurity requirements have been implemented.
When SSAT Is Required:
-
CII systems, or projects typically deployed or managed by Government agencies such as DSTA
-
Essential service projects involving IP-connected OT systems
-
Project Examples: CCTV, Building Management, Visitor Management
What SSAT Covers:
- System Hardening: Harden all systems according to CIS benchmark or OEM guidelines. Check out our affordable Engineering workstation hardening package here.
-
Host Configuration Review: Review of OS, application, network device, and firewall settings, aligned with CIS Benchmarks.
- Audit Logging: Ensure security logs are enabled, retained, and protected from tampering.
-
Vulnerability Assessment and / or Penetration Testing: Scanning and / or exploitation, with remediation likely for all findings, with waiver justification for the rest that cannot be remediate.
-
Evidence Collection: Screenshots, logs, config files, scan raw data may be required to be submitted for review.
- Performance / Load Test: Ensures your application can handle specified traffic levels, satisfying performance criteria outlined in Contract.

MAS-TRM – Technology Risk Management Guidelines
The Monetary Authority of Singapore (MAS) mandates the TRM guidelines for all financial institutions, including banks, insurers, and fintechs. Unlike SSCT, which is more of a checklist-based audit, MAS-TRM is principles-based.
Key Pillars of MAS-TRM:
-
Strong IT governance and risk ownership
-
Third-party risk management
-
Secure application development lifecycle
-
Incident detection and response
-
Cyber resilience and business continuity
TRM compliance is often assessed during licensing or thematic inspections and requires policies, system configurations, and real-world control effectiveness validated through Penetration test. Check out our cost-effective penetration testing packages to help you demonstrate TRM compliance.
