FROM CYBERSECURITY TO CYBER-RESILIENCE (PART 1): BUILDING A DIGITAL TRUST ECOSYSTEM

In today’s interconnected digital era, the focus is shifting from cybersecurity, which primarily defends systems, to cyber-resilience, which ensures continuous operation despite attacks. This transformation showcases the need for creating and maintaining digital trust across devices, applications, and users (people).

The old digital era was simpler, with fewer interconnected devices. Today, the landscape has exploded into a complex web of connected devices that interact through networks. This connectivity, while convenient, has introduced significant vulnerabilities and cases of digital arrests— situations where malicious actors compromise networks and use social engineering tactics to intimidate victims into believing they are involved in a fake legal issue, pressuring them to pay a suspicious amount of money to avoid alleged consequences.

THE PATH TO DIGITAL TRUST

To address these challenges, we implement and leverage:

• Trusted Networks: Devices must connect through secure channels that ensure data is protected in transit.

• Trusted Devices: Using only secure hardware that has been tested for vulnerabilities.

• Trusted Apps: Adopting applications with validated libraries, secure coding, and indigenous solutions to minimize dependency on potentially compromised third-party code.

• Trusted People: Establishing strong identity verification protocols.

  
  

ASSURING DIGITAL TRUST

1. Trusted Networks: Securing the networks

Key Question: Is HTTPS truly safe? 

While HTTPS provides encryption for data in transit, emerging technologies like quantum computing pose a threat. Attackers can harvest data today and decrypt it tomorrow when quantum capabilities mature. Thus, adopting post-quantum cryptography becomes essential for long-term data protection.

2. Trusted Devices: Securing the Foundation

Devices are the building blocks of the digital trust ecosystem, and their security is a must. Testing devices against specific attack vectors helps ensure resilience:

Side-Channel Attacks: Exploit unintended leaks from devices, such as electromagnetic emissions or power consumption, to infer sensitive data like encryption keys.

Example: An attacker measures power variations to decrypt secure communications.

Solution: Implement hardware shielding and constant-time algorithms to prevent data leakage.

Backdoors: Hidden vulnerabilities or intentional flaws left in devices during development that can be exploited to gain unauthorized access.

Solution: Conduct rigorous third-party audits and vulnerability assessments.

Fault Injection: Deliberately introduces faults (e.g., sudden voltage changes) into a system to manipulate its behaviour and extract sensitive data.

Solution: Use tamper-proof designs and fault-detection mechanisms in hardware.

Row hammer Attacks: Target vulnerabilities in DRAM memory. By rapidly accessing adjacent rows of memory cells, attackers can induce bit flips, altering stored data.

Solution: Employ error-correcting codes (ECC) and secure memory management practices.

3. Trusted Apps: Ensuring Software Integrity

Applications serve as the interface between users and devices. Compromised apps can nullify even the most secure devices. Building trusted apps involves:

• Secure Coding: Writing code that avoids common vulnerabilities, such as buffer overflows and SQL injection.

• Validated Libraries: Ensuring all libraries used are verified, up-to-date, and free from known vulnerabilities.

• Indigenous Solutions: Developing software in-house or sourcing it from trusted developers to reduce exposure to foreign threats.

4. Trusted Identities: Establishing Confidence in Entities

Digital trust requires trusted identities. This should uphold:

• Confidentiality: Data is accessible only to authorized parties.

• Authenticity: Verifying that entities are who they claim to be.

• Integrity: Ensuring data is not tampered with during transmission or storage.

• Non-Repudiation: Preventing entities from denying their actions.

5. Human Problem: The Weakest Link

Human error remains the most significant vulnerability. Solutions to address this include:

• Awareness and Training: Regularly educate users about phishing, social engineering, and secure practices.

• Multi-Factor Authentication (MFA): Minimize reliance on passwords alone.

• Digital Trust: Build systems that ensure users can trust the authenticity and security of what they interact with online.

THE ROOT OF TRUST

Establishing trust begins with the Root of Trust (RoT) - a secure and immutable foundation in hardware or software that underpins all cryptographic operations. It ensures a chain of trust across devices, applications, and users.

CONCLUSION

By focusing on a robust digital trust ecosystem, organizations can transition from merely defending against cyber threats to operating resiliently even during attacks. Trusted networks, devices, apps, and people—secured through innovations like post-quantum cryptography and strong identities—form the foundation for a secure, connected future.
