Protecting critical assets in a post-quantum world

The quantum revolution will pose significant threats to information security with its ability to analyze complex data, such as encryption algorithms, much faster than current computers. While experts are still debating the timeline of when quantum computing will surpass the speed and accuracy of classical computing, now is the time to prepare for its arrival. By 2030, estimates show there could be 2,000 to 5,000 quantum computers in the world.

Definition of Quantum Computing

Quantum computing will potentially solve problems far too complex for today’s classical computers. Conventional computers operate in the binary domain and therefore can only process one set of inputs and one calculation at a time. Think basic zeros and ones. Now enter quantum computing, which involves qubits – short for quantum bits, which are volatile and changeable in nature. Qubits allow quantum computers to simultaneously solve multiple calculations, each with multiple inputs. Quantum computers are expected to factor prime numbers and solve the algorithms behind many encryption keys, including RSA encryption algorithms, which are widely used by many organizations to protect data and their IT infrastructure.

The ramifications are profound if encryption algorithms are broken. The trust that has defined our digital existence will be forever affected. Hackers can now create fake certificates, calling into question the validity of every online digital identity or any data transmitted or received over the Internet.

The inevitable ability of quantum computers to perform algorithm-breaking calculations will require a mindset shift in how CISOs and CIOs secure sensitive and confidential data.

Act now to protect critical data and assets

If organizations wait until quantum computers are commercially available, it will be too late. Cybersecurity experts point to a critical threat known as Store Now, Decrypt Later (SNDL), where nefarious actors are now exfiltrating sensitive and confidential data with the intention of decrypting it once quantum computers are available. While there is no doubt that sensitive information is a concern when it comes to the threat of quantum encryption, the deepest threat lies with a company’s most critical assets or gems, which, if compromised, could pose an existential threat to the organization and its capacity. To work. Security teams must now make information such as security level data, intellectual property for patented research or drugs and protected health information proof against cyber adversaries who steal it in anticipation of availability possible quantum computers.

Get ready for the quantum future

To mitigate the threat of hackers, organizations need to strengthen their data security now. Yes, companies should invest in quantum-safe encryption solutions. However, security-focused organizations need to understand that advances in quantum technologies will eventually produce the next generation of computing that could potentially break the “quantum security” encryption algorithms.

Security-focused organizations understand this dilemma and are looking for solutions that prevent the exfiltration of critical digital assets in the first place. Security teams consider network obfuscation as a potential solution.

With network obfuscation, critical resources are hidden from the public internet and not visible even within the corporate network environment. Sensitive assets such as vital health records, confidential IP research, business applications, and even encryption algorithms are sealed off in an “invisible vault” that prevents unauthorized users from even knowing they exist.

Ransomware attacks are so damaging because nefarious actors are buried in an organization’s networks, undetected for weeks or months as they scout the company’s crown jewels and exfiltrate large amounts of data and credentials. By the time the ransom demands are made, the damage is already done. In the event of an SNDL breach, security teams often don’t learn of the consequences until much later.

Obfuscation protects a company’s most critical assets from an external bad actor or internal threat. They can’t see the obfuscation network that protects the organization’s assets if they don’t have access to it. They don’t know about the existence of the network or the critical assets that are protected within the network. Obfuscation also provides an added benefit by reducing the number of attack surfaces in the corporate network, as these assets are no longer visible to cyber adversaries.

Network obfuscation helps keep critical business assets and encryption algorithms quantum safe now, and ready for the threats of tomorrow.
