Guest blog by Savan Kishorbhai Padaliya, Senior Fullstack Blockhcain Developer at VE3 #techUKCyberInnovation

We are in an increasingly connected world where everything remains connected via the internet. Because of this vast internet exposure to digital infrastructure, the UK's critical national infrastructure (CNI) has to face severe cyber threats. Critical National Infrastructure (CNI) comprises numerous national-level services like energy, healthcare, transportation, and telecommunications. With the advancement of digitization, all of these run via the internet. Therefore, any compromise to these systems because of cyber attacks or digital threats could have devastating effects, not only on the financial stature but also on public safety.

So, now is the most pressing time to ensure CNI security. Let’s highlight how the UK's government & private firms like us have started harnessing emerging technologies to bolster the overall security & resilience of the UK's critical national infrastructure. We will also look at one case study of a financial institution to show how and what technologies do we leverage to defend against cyber threats. We will also provide a glimpse of the various technologies' utilization & why we have integrated them into our client's existing system.

Understanding Evolving Threat Landscape

Cyber threats and state-sponsored cyber attacks have become more common than ever in compromising critical national infrastructure. They pose a significant threat through various attack vectors like ransomware, denial-of-service (DoS) attacks, data breaches, customer and citizens' privacy leakage, and industrial control system (ICS) attack toolkits.

Because of the high stakes, attackers try to breach sensitive systems like financial services, healthcare databases, smart grids, energy system services, etc., causing severe disruption, panic, and physical damage. It also deteriorates the reputation of the country at large. Thus, nations like the UK are trying to make more resilient and robust digital infrastructure to protect against cyber threats.

Innovation in Cyber Security for UK's Digital Infrastructure

As the UK transforms into a digitally more interconnected and tech-driven nation, its critical national infrastructure (CNI) is increasingly vulnerable to cyber threats. All the CNI sectors, like energy, transportation, telecommunications, financial services, and healthcare, constantly rely on complex digital systems. To protect the digital infrastructure - the UK government has taken pivotal steps. It will help safeguard the UK's digital infrastructures through innovative cybersecurity techniques. Here are some emerging technologies that can address various security challenges on CNI.

Blockchain Technology: Blockchain technology has become an increasingly trending technology that secures digital transactions & detects fraudulent attempts automatically. It uses a decentralized & immutable ledger. The technology ensures that the blockchain user cannot alter any data or transaction without detection. It guarantees the integrity of information & helps protect critical data. The UK government uses blockchain technology to secure financial transactions, healthcare databases, and other industrial data assets.
Artificial Intelligence and Machine Learning: Artificial Intelligence and Machine Learning are two significant technologies of a single branch helping the UK government automate threat detection techniques. AI-powered tools can detect anomalies and identify attack vectors & threat patterns based on vast training data. Critical sectors like energy and telecommunications across the UK are deploying AI-driven threat intelligence platforms.
Zero Trust Architecture: Zero Trust Architecture (ZTA) is a state-of-the-art security strategy that considers that threats exist inside & outside the network. Rather than relying on traditional perimeter defenses, ZTA requires continuous verification of user/employee identities, devices, privileges, and access levels. This approach minimizes the risk of insider threats & unauthorized permits to critical systems. The UK government & private sector are increasingly adopting Zero Trust principles to secure critical infrastructure.

Case Study of How we can Help Secure Enterprise-Grade Systems

Various enterprises that offer state-of-the-art solutions for enterprise-grade systems are available. But our company is different. It uses innovative technologies to have a strong foothold in the cybersecurity domain. We offer emerging technology-driven solutions that leverage blockchain, enterprise-grade firewalls, and artificial intelligence (AI). Let us share one case study of the financial sector where we helped the financial service firm prepare with a 360-degree security solution.

Problem: Financial service companies are highly prone to cyber threats. It is because they deal with sensitive data, financial records, transaction details, and proprietary algorithms. For handling myriad cyberattacks like phishing, transaction fraud, data breaches, Man-in-the-Middle (MITM) attacks, & Distributed Denial of Service (DDoS) - the financial firm asked for a comprehensive security solution. That is where we come into the cyber rescue.

Client Challenge:

The client faced increasing difficulties in maintaining the integrity and security of their financial transactions in a rapidly evolving digital landscape. Traditional security measures, such as firewalls and database management, were no longer sufficient to combat the sophisticated threats targeting the financial sector. Specific challenges included:

Data Integrity Issues: Difficulty distinguishing legitimate from fraudulent transactions.
Weaknesses in Traditional Firewalls: Static firewalls couldn't keep pace with modern, adaptive cyber threats.
Internal and External Threats: The client needed more secure access management for employees.
Future Threat Preparedness: The client was concerned about future threats, particularly the advent of quantum computing.

Solution Overview:

To combat these challenges, we implemented a multi-layered cybersecurity strategy that includes:

Blockchain for Data Integrity
We transitioned the client’s traditional database to a blockchain-based system to ensure that their transaction data remains immutable and tamper-proof. Blockchain’s decentralized nature eliminated single points of failure and helped preserve the integrity of transactions.
AI-Powered Threat Detectors and Load Balancers
Traditional firewalls were upgraded with AI and ML-based threat detection systems. These AI-powered detectors monitored inbound and outbound data for unusual patterns, identifying potential cyber threats in real-time. Intelligent load balancers were integrated to manage traffic and protect against DoS and DDoS attacks.
Zero Trust Architecture with Advanced Cryptographic Algorithms
We implemented a Zero Trust Architecture, requiring employees to verify their identity at every point of access. This ensured that even internal threats were minimized. Advanced cryptographic algorithms secured communications and helped protect sensitive data from breaches and phishing attacks.
Quantum Cryptographic Algorithms
Recognizing the future risks posed by quantum computing, we integrated post-quantum cryptographic algorithms. These are designed to protect against the rapid decryption capabilities of quantum computers, ensuring long-term security for the client’s digital infrastructure.

Results:

After the implementation of these solutions, the client experienced significant improvements in their cybersecurity posture:

Enhanced Data Integrity: Blockchain technology ensured that all financial transactions were secure, immutable, and protected from tampering.
Proactive Threat Detection: AI-powered threat detectors minimized the time to identify and respond to cyberattacks, significantly reducing the risk of data breaches and fraud.
Improved Security Access Management: The Zero Trust Architecture reduced insider threats and provided an additional layer of protection against unauthorized access.
Future-Proofing with Quantum Cryptography: The integration of quantum cryptographic algorithms positioned the client ahead of future quantum threats, ensuring the long-term security of their systems.

Conclusion –

We hope this case study has provided a clear understanding of the various emerging technologies we use for our clients. Financial systems are the backbone of a nation. It comes under a critical national infrastructure that developed countries like the UK must protect. This is one angle where we have leveraged technologies like blockchain, AI-powered firewalls, intelligent load balancers, Zero Trust Architecture (ZTA), and advanced cryptographic algorithms to protect our client (financial service organization) from cyber threats.
