Germany jumps on the bandwagon of observing failing infrastructure and paranoid fear mongering to exploit opportunities created, pretending that poking at whats broken is a form of warfare generally laughed at by military engineering. DARPA invented the thing for communication, not to let it rot and force departments to build their own.

Best analogy is investing in cameras for the military camp because the gate will break soon.

In layman terms, what I suspect they actually mean. Is to invest in technology and engineering for Germany's network infrastructure. Sort of like idiot proofing bombs against accidental or intentional malicious detonation.

Treating parts of the network that way has been done in banking and finances for a very long time. Now it's important enough for a country and a state to make core infrastructure just as resilient as the the stock market.
