Crypto Agility: Why PQC Is a Continuous Network Security Practice
Crypto agility turns post-quantum cryptography migration into a continuous network security practice, not a one-time algorithm swap. Network teams need an inventory of cryptographic dependencies, platforms that can accept software and protocol updates, repeatable interoperability testing, and clear ownership for each change. PQC is the immediate pressure; the durable capability is the ability to replace algorithms, libraries, certificates, and protocol mechanisms again when standards or implementations change. Key Takeaway: Treat cryptography as a managed dependency across the network lifecycle: discover it, prioritize it, test changes, deploy in stages, verify behavior, and repeat. ...
