As Cambodia’s digital economy expands, the regulatory landscape governing cloud computing and cybersecurity in the banking and financial sector has evolved to ensure operational resilience, data security, and compliance. The National Bank of Cambodia (NBC) has established comprehensive frameworks through the Technology Risk Management Guidelines (2019). These policies provide a roadmap for Banking and Financial Institutions (BFIs) to securely adopt and manage technology solutions while mitigating associated risks.

In this article, we aim to inform IT professionals in Cambodia about the key elements of these NBC guidelines and their significance in the financial sector. We will also explore how service providers like GDMS and VNCS can assist in implementing these regulations effectively.

Cambodia’s Regulatory Landscape for Cloud and Cybersecurity

1. NBC Technology Risk Management Guidelines (2019)

This guideline provides a foundational framework for managing technology risks in the financial sector. Key focus areas include:

• IT Governance: Establishing robust structures to align technology strategies with organizational objectives.
• Cybersecurity Essentials: Implementing controls such as access management, network security, and vulnerability assessments.
• Business Continuity and Disaster Recovery (BCP/DR): Ensuring systems are resilient to disruptions and capable of rapid recovery.
• Information Security Audits: Maintaining audit trails and conducting periodic reviews to ensure compliance.

The NBC Technology Risk Management Guidelines outline specific cybersecurity tools and measures that every Banking and Financial Institution (BFI) in Cambodia should implement to ensure compliance, security, and operational resilience. These tools and practices include:

1. Identity and Access Management (IAM):
   • Implement role-based access control (RBAC) to restrict access to sensitive systems and data.
   • Enforce multi-factor authentication (MFA) to secure user authentication processes.
2. Network Security:
   • Use firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS) to protect network infrastructure.
   • Encrypt data during transmission using secure protocols such as TLS or IPSec.
3. Endpoint Security:
   • Deploy antivirus and anti-malware tools to safeguard endpoints from threats.
   • Use device control solutions to monitor and restrict access to physical devices like USB drives.
4. Threat Monitoring and Management:
   • Utilize Security Information and Event Management (SIEM) tools for real-time threat detection and response.
   • Continuously monitor logs and security events for anomalies.
5. Vulnerability Management:
   • Conduct regular vulnerability assessments and penetration testing to identify and address security gaps.
   • Patch management systems must be in place to ensure all software is updated promptly.
6. Incident Response Tools:
   • Maintain incident response plans (IRPs) with tools for detecting, analyzing, and mitigating security incidents.
   • Ensure rapid escalation procedures for significant security breaches.
7. Data Encryption and Privacy:
   • Encrypt sensitive data both at rest and in transit using robust encryption algorithms.
   • Implement tokenization or pseudonymization techniques to enhance data privacy.
8. Audit and Compliance Tools:
   • Maintain audit trails of all critical activities for accountability and compliance.
   • Use automated tools to generate reports for regulatory and internal audits.
9. Backup and Recovery:
   • Implement tools for regular data backups, ensuring they are secure and easily restorable.
   • Integrate disaster recovery systems that align with NBC’s Business Continuity Planning requirements.
10. Employee Awareness and Training:
    • Deploy training platforms to ensure staff understands cybersecurity policies and threat mitigation practices.

By mandating these tools and practices, the NBC aims to build a robust cybersecurity posture for Cambodian BFIs, reducing risks and enhancing trust in the financial system.

2. NBC Cloud Computing Risk Management Guidelines

Recognizing the growing adoption of cloud services, this guideline outlines specific measures to mitigate risks associated with cloud computing. Key aspects include:

• Data Sovereignty: Mandating that critical data be stored and processed within Cambodia.
• Risk Assessments: Conducting thorough evaluations of cloud service providers (CSPs) and their infrastructure.
• Data Security and Privacy: Requiring encryption, access controls, and regular security audits.
• Governance and Oversight: Establishing clear contractual agreements with CSPs to define responsibilities and handle incidents.
• Disaster Recovery and Exit Strategies: Ensuring CSPs align with BFIs’ BCP/DR plans and provide secure exit solutions.

The NBC Cloud Computing Risk Management Guidelines specifically address cloud hosting to ensure the security, compliance, and operational resilience of BFIs in Cambodia. Here’s what the guidelines say about cloud hosting:

1. Data Sovereignty: Critical data must be stored and processed within Cambodia unless explicitly permitted by regulators. This ensures compliance with Cambodian laws and protects sensitive financial data.
2. Risk Assessments: BFIs must thoroughly evaluate cloud service providers (CSPs), including their infrastructure, security controls, and operational resilience, before adopting their services.
3. Data Security and Privacy: Strong encryption for data at rest and in transit is required. Cloud hosting must include robust access controls and regular audits to ensure data security and privacy.
4. Governance and Oversight: BFIs must establish clear contracts with CSPs, outlining responsibilities, incident management procedures, and compliance obligations.
5. Disaster Recovery and Exit Strategies: CSPs must align with BFIs’ disaster recovery plans and provide secure data migration and deletion processes during transitions.
6. Compliance Monitoring: Regular evaluations and monitoring of the CSP’s adherence to service level agreements (SLAs) and regulatory standards are mandated.

These measures are designed to mitigate risks associated with cloud adoption while promoting secure and compliant hosting practices.
