The advent of functional quantum computing represents one of the most significant shifts in the history of information security. While the full realization of Cryptographically Relevant Quantum Computers (CRQCs) may still be a few years away, the implications for Governance, Risk, and Compliance (GRC) are immediate. At iExperts, we are already seeing a shift in how regulatory bodies view encryption. The strategy of Harvest Now, Decrypt Later means that data captured today could be exposed tomorrow, making quantum-resistance a matter of current risk management, not just future planning.

The Evolution of ISO/IEC 27001:2022

The latest iteration of ISO/IEC 27001:2022 has already laid the groundwork for more robust cryptographic controls. Annex A Control 8.24 focuses on the use of cryptography and specifically requires organizations to define a policy for the use of cryptographic controls. As we move toward 2030, we expect this control to evolve from simple encryption requirements to mandatory Post-Quantum Cryptography (PQC) readiness. Organizations will need to inventory every instance of public-key infrastructure (PKI) within their environment to assess vulnerability.

"The transition to quantum-resistant algorithms is not a single event, but a multi-year governance journey that requires total visibility into your cryptographic supply chain."

PCI DSS 4.0 and the Future of Payments

The PCI DSS 4.0 standard has introduced more flexibility, but also more responsibility. Requirement 4 mandates the protection of cardholder data during transmission over open, public networks. In a post-quantum world, current TLS and SSL standards will no longer suffice. The iExperts strategy for payment security involves:

• Algorithm Inventory: Identifying all RSA and ECC instances that currently secure transactional data.
• Phased Migration: Implementing hybrid cryptographic schemes that combine classical and quantum-resistant algorithms.
• Vendor Assessment: Ensuring third-party processors are actively roadmapping their transition to NIST-approved PQC standards.

Pro Tip: Prioritize Cryptographic Agility

One of the most effective ways to prepare for 2030 is to build Cryptographic Agility into your architecture. This means designing systems that can quickly switch between different encryption algorithms without requiring fundamental changes to the underlying infrastructure. This agility is becoming a core component of the NIST CSF 2.0 framework, particularly under the 'Govern' and 'Protect' functions.

Key Deliverables for Quantum Readiness

To ensure your GRC posture remains resilient, iExperts recommends focusing on these immediate action items:

• Cryptographic Asset Discovery
• Quantum Risk Impact Assessment
• Algorithm Migration Roadmap

The transition to a quantum-resistant future is complex, but it does not have to be overwhelming. By integrating quantum risks into your existing GRC frameworks today, you secure your organization's longevity. The team at iExperts is dedicated to helping you navigate these shifting standards with precision and authority.
