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
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. Discover why building a comprehensive cryptographic inventory and executing a phased operational strategy are critical for protecting your data against quantum computing attacks. Key takeaways Quantum computing risks are an operational threat today due to "harvest now, decrypt later" (HNDL) tactics, in which adversaries actively harvest and store encrypted data to decrypt it retroactively once quantum capabilities mature. When run…
