Quantum Cyber Security: How to Manage This Threat?
As a business or IT professional, you are accustomed to the constant evolution of cybersecurity threats. You've adapted to cloud security challenges, managed the risks of AI-driven attacks, and implemented multi-factor authentication.
But what happens when the very foundation of modern cryptography is at risk? A new, paradigm-shifting challenge is on the horizon: quantum cybersecurity. This isn't science fiction; it is a serious quantum threat that demands your attention and proactive preparation.
What is a Quantum Computer?
A quantum computer is a revolutionary machine that harnesses the principles of quantum mechanics, such as superposition and entanglement. Unlike traditional computers that use bits (1s or 0s), quantum computers use qubits, which can exist as a 1, a 0, or both simultaneously.
This allows them to perform certain calculations exponentially faster than even the world's most powerful supercomputers, with profound cybersecurity implications of quantum computing.
Quantum Computing’s Threat to Organizations
The core quantum computing threat lies in its ability to break the public-key encryption standards that secure virtually all of our digital life today.
Algorithms like RSA and Elliptic Curve Cryptography (ECC) rely on mathematical problems that are currently too difficult for classical computers to solve.
A powerful quantum computer, however, equipped with an algorithm like Shor's, could solve these problems in a matter of hours or days.
This poses significant quantum computing risks to your organization's sensitive data, compromising secure communications, financial transactions, and intellectual property. The dangers of quantum computing are not just future concerns; a critical quantum computing security risk is the "harvest now, decrypt later" attack, where adversaries steal your encrypted data today, knowing they will be able to decrypt it years from now when powerful quantum computer cybersecurity becomes a reality.
This makes the risks of quantum computing an immediate and pressing concern for your long-term data security.
CyberGuard’s Take on Quantum Cyber Security Threats
In a recent podcast by Rixon Technology, CyberGuard Advantage’s own Sajeev Prelis, Executive Vice President of Technical Sales, provided a critical take on the emerging quantum threat.
During the "Well, Fix It Before the Quantum Apocalypse. Probably" episode by Rixon Security, Prelis underscored the urgency of going further than just being compliant with the industry standards.
“The compliance standard is a minimum (standard). Security needs to be much higher”, commented, arguing that if companies want to be prepared for the quantum threats, they need to start developing stronger security systems that go beyond the basics.
He also added that organizations are getting a false sense of security, and most of the businesses are not taking into consideration the benefits cybercriminals are getting to make their systems vulnerable.
“Cybercrime is very incentivized compared to a company's security budget”.

How to Prepare for Quantum Cyber Security?
So, how is your organization preparing for the post-quantum world? The path to a resilient security posture involves concrete steps you can take today.
- Audit Your Cryptographic Inventory: First, you need to understand what you have. Identify all systems, applications, and data that use public-key cryptography. This is the foundation of your quantum computing cybersecurity plan.
- Embrace Crypto-Agility: Your systems should be designed with the flexibility to quickly swap out cryptographic algorithms. This "crypto agility" is essential for a smooth transition to quantum computing cybersecurity standards, which will eventually replace current protocols.
- Develop a Strategic Roadmap: Work with your leadership and IT teams to create a multi-year plan for migrating to new, quantum-safe algorithms. This plan should prioritize your most critical systems and long-term data.
- Stay Informed on Post-Quantum Standards: The National Institute of Standards and Technology (NIST) is actively standardizing new quantum-safe algorithms. Stay up to date with these developments to ensure your migration plan aligns with accepted standards.
By taking these steps, you demonstrate that your organization is preparing for a postquantum world, safeguarding your digital future against the coming quantum threat. The time to act is now, well before the era of quantum hacking becomes a reality.
