Why a cryptographic inventory is key for addressing the quantum computing threat
Tenable argues organizations need cryptographic inventories and phased plans to counter harvest-now-decrypt-later quantum attacks.
Tenable's blog warns that quantum computers will eventually break current public-key cryptographic algorithms, and that "harvest now, decrypt later" collection makes the risk operational today. It recommends building a comprehensive cryptographic inventory and executing a phased operational strategy to migrate toward quantum-resistant protection for stored and transmitted data.
- Harvest-now-decrypt-later (HNDL) tactics make quantum risk immediate for encrypted data
- Comprehensive cryptographic inventory framed as the foundation of PQC readiness
- Phased operational strategy recommended for post-quantum migration
From the original article
When quantum computers become generally available, they’ll be able to crack current public-key cryptographic algorithms, putting digitally stored and transmitted data at risk. But the threat already exists, as attackers use the "harvest now, decrypt later" tactic.
