Three Major Attacks in Two Years - Time to Put Our Engineers Hats On

"Ko e Otua mo Tonga ko hotau tofi'a" - God and Tonga are our inheritance King Tupou VI

The Reality Check We Needed

This is indeed a great start, we are finally heading in the right direction. Yes, in this day and age, Information Security (Infosec) is common practice. Moreover, we now have the Government's Digital Transformation and Cybersecurity Frameworks published online.

However, three official major attacks in 2+ years signifies that our greatest strength is still our weakest link i.e. the human aspect.

Having said that, we have our policies in place, but we all know that adhering to policy discussions only camouflages technical incompetencies. Therefore, let's put our Engineers hats "ON" and dig deeper to find out our vulnerabilities as root causes of our problems.

The Harsh Truth - Policy ≠ Protection

While Tonga has made commendable progress in establishing cybersecurity frameworks and digital transformation policies, the stark reality is that paper shields don't stop digital bullets. Three major cyber attacks in just over two years isn't bad luck, it's a systemic failure of our cybersecurity infrastructure where both technical and human aspects are critical components.

The Attack Timeline - A Pattern Emerges

March 2023 - Tonga Communications Corporation (TCC)

June 2025 - Ministry of Health (MOH)

2025 - Tonga Power Limited (TPL)

Technical Vulnerabilities - The Real Engineering Problem

Let's stop sugar-coating the situation with policy rhetoric and examine the actual technical deficiencies that enabled these attacks:

1. Legacy Infrastructure Exposure

The Problem: Some of Tonga's critical infrastructure relies heavily on outdated systems with known vulnerabilities.

Technical Reality:

Engineering Solution Required: Complete infrastructure modernization with zero-trust architecture.

2. Inadequate Network Security Architecture

The Problem: While our government network infrastructure is well designed with SOC team management and vendor independence, the challenge lies in continuous monitoring with proactive rather than reactive response capabilities.

Current Strengths:

Technical Gaps to Address:

Engineering Solution Required: Build upon our solid foundation with enhanced defense-in-depth, real time monitoring and automated response while maintaining our vendor independent approach.

3. Data Protection Failures

The Problem: Critical government data lacks proper encryption and access controls.

Technical Deficiencies:

Engineering Solution Required: End-to-end encryption with hardware security modules and multi-factor authentication.

4. Incident Response Inadequacy

The Problem: When attacks occur, our response is reactive rather than proactive.

Operational Gaps:

Engineering Solution Required: 24/7 SOC with automated playbooks and local expertise.

The Pacific Context - Why Small Islands Are Prime Targets

Cyber criminals aren't randomly selecting Tonga, we represent an attractive target profile:

Target Characteristics

Regional Pattern Analysis

The attacks on Tonga mirror a broader Pacific trend:

Engineering Insight: Pacific Island nations need specialized cybersecurity architectures designed for geographic and resource constraints.

Engineering Solutions - Beyond Policy Papers

2. Zero-Trust Government Network Architecture

Implementation Strategy:

Citizen Access → API Gateway → Identity Verification → 
Ministry Specific Networks → Encrypted Data Storage → 
Immutable Audit Trail → Real-time Monitoring

Key Components:

3. Proof-of-Authority Blockchain for Government Services

Technical Benefits:

4. AI-Powered Threat Detection and Response

Capabilities:

The Cost of Inaction - Economic Reality

Direct Attack Costs

Indirect Economic Impact

Investment vs. Risk Calculation

DePIN Infrastructure Investment Summary:

ROI Analysis:

Investment Strategy: Leveraging existing government assets (buildings, Starlink, network equipment) to minimize costs while maximizing security resilience through solar-powered, decentralized infrastructure.

Cost Optimization Through Digital Sovereignty:

Recommendations - Engineering-First Approach

Immediate Actions (0-6 months)

  1. Top Priority: Modification and updates to current policies - Drive innovation and recommendations to align with technical realities
  2. Empowerment of Tonga CERT - Enhanced capabilities in both human and technical resources to become our first line of defense as in proactive response rather than reactive, more to empower our local expertise to handle our own defenses rather than always looking abroad to overseas consultants
  3. Awareness campaigns with capacity building - Upgrading our human resource cyber safety skills and cleanliness
  4. Emergency Security Assessment: Complete penetration testing of all critical systems
  5. Incident Response Team Enhancement: Strengthen local capabilities with international support agreements
  6. Critical System Isolation: Air-gap essential infrastructure from internet-facing systems
  7. Advanced Staff Cybersecurity Training: Technical skills development beyond basic awareness

Medium-term Implementation (6-18 months)

  1. DePIN Pilot Project: Start with MEIDECC as proof-of-concept
  2. Zero-Trust Network Deployment: Implement across core ministries
  3. SOC Establishment: 24/7 monitoring and response capabilities
  4. Backup Infrastructure: Distributed, encrypted, and regularly tested

Long-term Transformation (18-36 months)

  1. Complete Infrastructure Overhaul: DePIN-powered government network
  2. Blockchain Government Services: Immutable, transparent, and efficient
  3. Regional Cybersecurity Hub: Pacific Islands cooperation center
  4. Cybersecurity Workforce Development: Local expertise building

Update - Collaborative Engineering Consensus Reached

Following productive discussions with cybersecurity colleagues across government, we have reached consensus with the conclusion that our greatest strength is still our weakest link i.e. the human aspect.

Beyond Training:

Network Segmentation:

SOC Capabilities:

Power and Backup Connectivity:

The DePIN Implementation Path Forward

Looking ahead: The vendor independent approach aligns perfectly with the MEIDECC DSS and Performance Indicator Dashboard. This will demonstrate how distributed infrastructure can provide both resilience and independence from traditional vendor dependencies.

Our foundation is solid. We're moving from "adequate security" to "resilient security", which is exactly what we need given the targeted attacks we have experienced.

The government's scalable approach puts us in a great position for the DePIN infrastructure rollout.

Conclusion: Engineering Our Digital Sovereignty

The three major cyber attacks on Tonga revealed a fundamental truth i.e our greatest strength i.e. our human aspect is also our weakest cybersecurity link. But this collaborative engineering approach demonstrates that we can transform this challenge into innovation.

The engineering reality is now clear:

The collaborative path forward:

As engineers and technologists working together, we have the opportunity to transform this crisis into the most innovative government infrastructure in the Pacific. The DePIN model will demonstrate that small island nations can achieve both digital sovereignty and cybersecurity resilience.

The question isn't whether we can afford to implement these solutions, it's whether we can afford not to lead this transformation.

"Ko e Otua mo Tonga ko hotau tofi'a" means our inheritance includes both our islands and our responsibility to protect them in the digital age. Let's stop talking about cybersecurity and start re-engineering it.
