A fiber optic link can be tapped without being cut, without triggering an alarm, and without degrading the connection in any way a standard monitoring dashboard would notice. That’s not a hypothetical — it’s a documented capability using ordinary, commercially available telecom hardware. The harder question, and the one most comparisons of encryption, post-quantum cryptography, … Read more
CNSA 2.0 compliance for government and defense contractors runs on four dates, not one: January 1, 2027 for new National Security System acquisitions, 2030 for software, firmware, and networking equipment, 2031 for Department of War systems in active use, and 2033 for the remaining categories. Most coverage of this topic leads with 2033. This guide … Read more
Unrecordable optical transmission works by reshaping the light itself at Layer 1, so an attacker who taps the fiber captures noise rather than a usable copy of the traffic, and it is rolled out one link at a time as an overlay on existing optical infrastructure rather than a network-wide redesign. The sections below break … Read more
A quantum readiness roadmap runs six steps — cryptographic inventory, risk-based prioritization, migration strategy selection, PKI preparation, phased deployment, and ongoing crypto-agility — and even a perfectly executed version of it leaves one gap open: data already recorded off the wire before migration finishes. This guide breaks down the roadmap itself, where it stops covering … Read more
Yes, fiber optic cables can be tapped, and a well-executed tap doesn’t need to cut the fiber or interrupt the signal to do it. This guide covers exactly how a fiber tap works, where the weak points in a typical network sit, what detection methods actually catch and where they fall short, and how the … Read more
Harvest-now-decrypt-later (HNDL) is an attack strategy where an adversary intercepts and stores encrypted network traffic today with the intent of decrypting it once a quantum computer or other future technology can break the key exchange that protected it. Standard encryption does not prevent this, because it protects the meaning of a signal without preventing that … Read more
Implementing post-quantum encryption for data-in-transit means migrating the key-exchange step in TLS, VPNs, and IPsec to NIST’s ML-KEM standard, typically run in hybrid mode alongside existing algorithms during the transition. That covers the cryptographic layer. It does not, on its own, stop already-recorded traffic from being decrypted once quantum computers catch up — a separate … Read more
Physical-layer, or photonic-layer, optical security integrates into a network by substituting a standard transmission line card rather than adding a standalone appliance, and it supports three deployment topologies: point-to-point, ring, and full metro or long-haul network. This guide breaks down how that integration actually works, what a real field validation looked like, where the approach’s … Read more
Unrecordable optical transmission is a physical-layer defense that turns a fiber signal into indistinguishable noise, so intercepted traffic has nothing usable in it even if it’s captured today and analyzed years from now. This guide breaks down why standard encrypted fiber still fails against harvest-now-decrypt-later attacks, how unrecordable transmission actually works, where it deploys in … Read more
