      Cybersecurity Negligence and Personal Liability: What CISOs and Board Members Need to Know

      “Could I personally be sued or fined if our company gets breached?” This uneasy question is crossing the minds of many CISOs and board members lately. High-profile cyber incidents and evolving regulations have made it clear that cybersecurity is not just an IT problem - it’s a corporate governance and legal liability issue. Defining “Reasonable” Cybersecurity: From Learned Hand to Global Standards What does it…

      Quantum Security: Understanding the Terminology and Context

      "Quantum security" is a term that is increasingly being used. With everyone having their own definition of the term. It can carry multiple meanings depending on context, but so do other related terms. The whole field is fairly new and related terms are not yet clearly defined. So this is my attempt to untangle the ambiguity by exploring what quantum security commonly refers to, how…

      Upgrading OT Systems to Post‑Quantum Cryptography (PQC): Challenges and Strategies

      Operational Technology (OT) environments, such as industrial control systems and critical infrastructure, are especially at risk due to their long-lived devices and infrequent updates. Many OT systems deployed today will still be in use a decade or two from now, well within the timeframe experts anticipate quantum attacks to become practical. The most critical OT systems will likely be the last to become quantum safe…

      Quantum Risk: The Coming Cryptography Reckoning

      In a secure data center somewhere, an adversary is quietly stockpiling encrypted emails, financial transactions, and state secrets - betting that within a decade a new kind of machine will decrypt them in minutes. This scenario underpins what cybersecurity experts are calling "quantum risk." In essence, quantum risk is the looming threat that advances in quantum computing will shatter the cryptographic safeguards protecting our digital…

      Cryptographic Stack in Modern Interbank Payment Systems

      International interbank payments rely on multiple layers of classical cryptography to ensure security from end to end. When a user initiates a cross-border transfer at their local bank, cryptographic mechanisms protect the transaction at every stage - from the customer’s online banking session, through the bank’s internal systems, across the SWIFT interbank messaging network, to settlement in a central Real-Time Gross Settlement (RTGS) system.

      Post-Quantum Cryptography (PQC) and Network Connectivity: Challenges and Impacts

      PQC brings new dependencies between cryptography and network connectivity. Unlike the relatively small and efficient crypto of the past, post-quantum algorithms force us to consider link capacity, latency, and device limitations as first-class concerns in security design. Some network environments - particularly low-power and low-bandwidth links - will face significant challenges in a post-quantum migration, potentially impacting communication reliability. Other environments, like typical broadband and…

      What Will Really Happen Once Q-Day Arrives – When Our Current Cryptography Is Broken?

      As the world edges closer to the era of powerful quantum computers, experts warn of an approaching “Q-Day” (sometimes called Y2Q or the Quantum Apocalypse): the day a cryptographically relevant quantum computer can break our current encryption. Unlike the Y2K bug—which had a fixed deadline and was mostly defused before the clock struck midnight—Q-Day won’t announce itself with a clear date or time. We won’t…

      Q-Day Predictions: Anticipating the Arrival of CRQC

      While CRQCs capable of breaking current public key encryption algorithms have not yet materialized, technological advancements are pushing us towards what is ominously dubbed 'Q-Day'—the day a CRQC becomes operational. Many experts believe that Q-Day, or Y2Q as it's sometimes called, is just around the corner, suggesting it could occur by 2030 or even sooner; some speculate it may already exist within secret government laboratories.
