Sorry Dave, but you aren't reading the same articles and seeing the
same reports that I am.
Cyberassaults reveal China's growing interest in information
warfare, putting the Pentagon on guard against nation-state attacks.
>snip<
>>>Walt, what would make an HF-based system constucted by amateurs
invulnerable to cyber-attack?
### If you are NOT connected to the Internet and don't use 100% Internet
protocols, it would be almost impossible to attack the network except at the RF
level and if that is done 1) you and you enemy lose use of the frequency and 2)
you can be DFed and your "jamming station/site" be "taken out."
NO, amateur radio cannot build or operate a messaging network
anywhere close to what the Internet provides. That is NOT the
ideas. The idea is to provide some level of messaging that could
assist the federal, state and local governments as well as NGOs who
would support emergency or disaster recovery if part or all of the
Internet were rendered unusable.
>>>Several times in this thread, I have agreed that overcoming local
internet outages would be a reasonable objective. Its your
insistence that we must cover for the loss of the entire internet
that remains completely unjustified.
### No insistance that we must do anything. I am only saying that it is very
possible according to "experts" that the Internet could be attacked at the
software level and rendered inoperatable. Then providing local Internet
capability is of no great use if the local area does not have connectivity
outside the local area.
### Local law enforcement and governments might not be able to contact their
state counterpart and states might no be able to contact the federal
government. And in many cases, local governments and law enforcement need
contact at the federal level. Thus there is a need for the local area to
connect to the entire Internet. If the Internet does not exist, how do a local
area connect to the state of federal government?
>snip<
Satellites and fiber are hardware and are not affected by cyber-
attacks...its the software that runs over the hardware that is in
danger.
>>>So are you suggesting that this amateur-built HF world-wide
messaging system should not employ software?
### Not at all. I am saying that it is the software that is attacked not the
hardware. And that the software is attacked because it is running on the
Internet.
### Speaking of hardware, if you are aware of the public documents on the
Internet that show the physical location of major backbone hubs...physical
connections, then you would realize that 21 well placed and well times
explosive events (attacks) on those physical locations could disconnect the
Internet for several days, perhaps weeks, until the connections could be
rerouted.
I'm not Chicken Little. However, when individuals who know about
cyber-attacks and the capabilities of the Internet to survive a
large attack by our enemies, I become concerned.
>>>I agree that there's cause for concern, but I don't see how the
approach you're suggestion would come anywhere close to addressing
this problem.
### It approaches the problem in that it can be a small part of the solution.
THe DHS had envisioned using an amateur radio national messaging system for
delivery of critical loss of life and properity messages to various NGOs
(non-govermental organizations). Where information from one remote Zipcode
could be delivered to another Zipcode (large area not specifically individual
Zipcodes) and then the USPS would deliver the messages.
### One of the most critical areas was message delivery from the D.C. area
(Beltway) to the Boston area.
