Introduction

Critical Information Infrastructure (CII) plays a fundamental role in maintaining the essential services that societies and economies depend on. Sectors such as energy, banking and finance, healthcare, telecommunications, water, transport and government rely on interconnected digital systems to deliver uninterrupted services.

As cyber threats become increasingly sophisticated, protecting these systems requires more than traditional cybersecurity controls. Organisations must establish a structured approach to identifying vulnerabilities, managing cyber risks, responding to incidents and maintaining operational continuity.

In Singapore, the Cybersecurity Act and the Cybersecurity Code of Practice (CCoP) establish important cybersecurity obligations for designated CII owners. The 2026 regulatory landscape places continued emphasis on strengthening cyber resilience, improving security governance and ensuring that critical systems can withstand and recover from cyber incidents.

For CII owners, understanding the applicable CCoP requirements is essential to maintaining security, protecting sensitive information and supporting the continuity of essential services.

Understanding CCoP 2026 and Its Regulatory Requirements

The Cybersecurity Code of Practice for Critical Information Infrastructure 2026 was issued by Singapore’s Cyber Security Agency (CSA) on 29 July 2026, superseding the previous 2022 edition. It establishes minimum cybersecurity requirements that CII owners must implement to protect their critical systems and interconnected infrastructure. Compliance is mandatory under Section 35A(6) of the Cybersecurity Act 2018.

The updated CCoP addresses the growing risks associated with Advanced Persistent Threats (APTs), artificial intelligence-enabled attacks, interconnected networks and evolving digital infrastructure.

The framework focuses on several important areas:

• Cybersecurity governance: Establishing clear accountability at board and senior management levels.

• Risk management: Identifying, assessing, prioritising and managing cybersecurity risks.

• Asset identification: Maintaining visibility of CII assets and interconnected systems.

• Security protection: Implementing access controls, network segmentation, system hardening and vulnerability management.

• Threat detection: Strengthening monitoring, logging, threat intelligence and threat-hunting capabilities.

• Incident response and recovery: Developing structured response procedures and recovery strategies.

• Operational Technology (OT) security: Protecting industrial systems, control networks and critical operational environments.

   

Importance of Cybersecurity Assessment for CII Owners

A structured cybersecurity assessment helps CII owners understand whether their current security infrastructure can withstand modern cyber threats and meet the requirements of CCoP 2026.

Critical infrastructure environments often involve interconnected IT systems, operational technologies, cloud platforms, third-party services and remote access facilities. A weakness in one component can potentially expose other connected systems.

The following areas highlight why regular security assessments are essential.

1. Identifying vulnerabilities before attackers exploit them

Vulnerability assessments help identify outdated software, insecure configurations, exposed services, weak authentication mechanisms and other security weaknesses. Addressing these vulnerabilities reduces the likelihood of unauthorised access and system compromise.

2. Protecting interconnected systems

CCoP 2026 extends specific security requirements to interconnected systems owned, operated or controlled by CII owners. Assessments help identify security gaps in systems that communicate with critical infrastructure, reducing the possibility of attackers using less-protected systems as entry points.

3. Strengthening threat detection capabilities

Organisations need sufficient visibility across their networks to identify suspicious activities. Security assessments can evaluate logging, monitoring, detection mechanisms and incident escalation processes.

4. Improving incident response and operational continuity

A security incident affecting essential services can result in operational disruption, financial losses and reputational damage. Assessments help evaluate whether incident response, backup, restoration and disaster recovery arrangements are capable of supporting timely recovery.

5. Supporting regulatory readiness

Independent security testing and documented remediation activities help organisations identify gaps against applicable CCoP requirements. This supports more structured compliance preparation and provides evidence of security improvement.

Our Methodology for CCoP 2026 Cyber Resilience Assessments

Cyberintelsys follows a structured, risk-based methodology to help organisations evaluate their cybersecurity posture against the requirements of CCoP 2026. The assessment approach considers the organisation’s technology environment, operational requirements, security controls and applicable regulatory obligations.

1. Scope Identification and Asset Discovery

The initial stage involves understanding the organisation’s critical infrastructure environment.

Activities include:

• Identifying critical IT and OT assets, applications, servers and network components.

• Reviewing network architecture and system connectivity.

• Identifying interconnected systems and external access points.

• Understanding third-party dependencies and cloud-based infrastructure.

• Establishing the scope and objectives of the security assessment.

2. Cybersecurity Risk Assessment

Potential threats and vulnerabilities are evaluated based on their likelihood and potential operational impact.

The assessment considers:

• Existing cybersecurity controls and security policies.

• Threat scenarios involving ransomware, malware, phishing and unauthorised access.

• Vulnerabilities affecting critical systems.

• Risks associated with privileged accounts and remote connectivity.

• Residual risks and existing mitigation measures.

Identified risks are prioritised to support informed remediation decisions.

3. Vulnerability Assessment and Penetration Testing

Technical security testing is conducted to identify exploitable weaknesses in the organisation’s infrastructure.

This may include:

• Network vulnerability assessment.

• External and internal infrastructure testing.

• Web application security testing.

• Configuration and system security reviews.

• Privilege escalation and access control testing.

• Controlled penetration testing to validate identified weaknesses.

Testing activities are planned and authorised to minimise disruption to critical operations, particularly within OT environments.

4. Security Control and Architecture Review

Existing security controls are evaluated to determine whether they adequately protect critical infrastructure.

This includes reviewing network segmentation, endpoint protection, access management, system hardening, patch management, encryption and security monitoring capabilities.

5. Reporting and Remediation Planning

Findings are documented according to their severity, potential impact and exploitation risk.

Cyberintelsys provides technical reports containing identified vulnerabilities, supporting evidence, risk ratings and recommended remediation measures. These findings help organisations establish corrective action plans and track security improvements.

6. Validation and Continuous Improvement

Following remediation, identified vulnerabilities can be retested to verify whether corrective measures have been implemented effectively. Periodic reassessments help organisations adapt their security controls to changing infrastructure and emerging threats.

This methodology supports the risk identification, analysis, evaluation and response approach outlined in CCoP 2026.

Cyberintelsys Services for CCoP 2026 Readiness

Cyberintelsys offers cybersecurity assessment and testing services to help organisations identify security weaknesses, strengthen infrastructure protection and improve their readiness against applicable CCoP 2026 requirements.

The following services can support different aspects of a CII owner’s cybersecurity improvement programme.

1. Vulnerability Assessment (VA)

Vulnerability Assessment identifies security weaknesses across an organisation’s IT infrastructure, networks, applications and systems.

The service includes:

• Identifying outdated software, insecure configurations and exposed services.

• Detecting known vulnerabilities across network infrastructure.

• Evaluating security weaknesses in operating systems and applications.

• Prioritising vulnerabilities based on severity and potential business impact.
