New WiFi HaLow Protocol May Bring Old Security Issues With It
Trailrunner7 writes: Perhaps because smart lightbulbs that refuse firmware updates and refrigerators with blue screens of death aren't enough fun on their own, a new WiFi protocol designed specifically for IoT devices and appliances is on the horizon, bringing with it all of the potential security challenges you've come to know and love in WiFi classic. The new protocol is based on the 802.11ah standard from the IEEE and is being billed as Wi-Fi HaLow by the Wi-Fi Alliance. Wi-Fi HaLow differs from the wireless signal that most current devices uses in a couple of key ways. First, it's designed as a low-powered protocol and will operate in the range below one gigahertz. Second, the protocol will have a much longer range than traditional Wi-Fi, a feature that will make it attractive for use in applications such as connecting traffic lights and cameras in smart cities. But, as with any new protocol or system, Wi-Fi HaLow will carry with it new security considerations to face. And one of the main challenges will be securing all of the various implementations of the protocol.
I've always wanted to be able to control traffic lights.

a way to put offline all these CCTV cameras in Europe's cities. Or aim them at the heavens. Bring it on !

The article basically says all this could happen. It says nothing about the new protocol; nor does it talk about anything specific that's known about it.
It pretty much boils down to "here's a new protocol, and since new protocols often have security holes, this one may also have security holes."

The problem is none of the bands are wide enough to really provide the bandwidth that is desired. They keep trying new stuff which means every device must again have different chips in order to work. But something always seems to be lacking either in range, conflicts with other signals or a lack of real world speed because of range and signals. So now we go backwards from 5Ghz to under 1Ghz to try and fix range issues. Trouble is the range improvements may only add to another layer of cross path signal problems. The only reason 5Ghz worked so well with speed was that range kept the signals from competing and interfering and that it had plenty of channels to spread out the spectrum. If we could have done this with 2.4Ghz in the first place. That would have been a much better solution. We now know that 5Ghz has too many range and limitations due to lack of penetrating solid objects like walls and such. The IEEEE is the Goldilocks looking for the perfect spectrum and I am not sure that's even realistic.
TFA is pure unadulterated FUD
I am Slashdot. Are you Slashdot as well?
Noted how they're tweaking the laws to have a "terrorism" special case everywhere?
Given the flexibility of the label, perhaps just having an nmap or a wireshark could get any of us in jail. Spreading about protocols with fat and enticing vulnerabilities is the best bait to catch all-too-curious people.
Collaterals? Nah, we learned to cope with that.
Does anyone else around here ever get tired of being a Cassandra?
People won't heed warnings about stupid new 'tech devices'. But 10 years later, once it has bitten them in the ass, they complain to us that we weren't emphatic enough.
Society gets what it asks for.
Bonus points for overuse of the word "protocol".
By the way, the "much longer range" (debatable)...that's a function of the wavelength guys, not the protocol.
Anyway, dupe. Was widely discussed here the other day; can be bothered to find TFA.
Was a nice nerdy conversation about range vs. antenna design vs. signals stomping all over each other...

Don't see how this will bring any more - or less -security. If, and it's a big if, people learn from the mistakes of the past, then our previous experiences with wifi should make people more aware of the design risks and take proper steps to secure stuff.
Of course, with all of the continuing revelations about hard-coded passwords, crap firmware and backdoors in everything from routers (both pro and consumer grade), "smart" meters and "smart house security solutions" *cough* the betting is probably that cheapo IoT devices will be as insecure as hell.
But that's hardly the fault of the standard...
More "favorable" propagation maybe (for certain values of favorable)
It'll have better range for the 6 months it takes the 900Mhz band to get shitted up with the 100's of devices now all within sight of each other and the digital screaming match begins. Remember when 2.4Ghz wifi would get you out the front door and 50 yards down the road, and how nowadays it'll barely get from the living room to the bedroom.
The next release of the Linux kernel could contain old security problems. The next release of OS X could contain old security problems. The next smart card standard could contain old security problems.
What I still can't grasp is this: apart from certain niche applications, why would anybody want a 'smart lightbulb'? And the wider question - isn't the whole IoT thing a solution looking for a problem to solve? So far, I can't for the life of me see a convincing reason to invest in the gadgets that have been proposed so far - kitchen appliances on the internet? Thermostats? I suppose home-surveillance might be somewhat interesting, but wouldn't it be rather light hearted to connect cameras looking at your private life etc directly to the open internet? "Oh, look, they've got a rather good collection of Royal Doulton statuettes, and a nice TV. And they always go away over the weekend ..."
Actually, part of the protocol describes how the binary signal is mapped to analog (as radio is really an analog signal). The effective range is approximately determined by the distance at which noise overtakes the signal. Now, wavelength-dependent attenuation determines how quickly the signal degrades, and the noise typically is also wavelength-dependent. That indeed is independent of protocol. However, some protocol choices are more noise-tolerant than others. ADSL famously estimates noise to choose different analog representations, in order to maximize bandwidth.
Back on topic, a good design can in fact prevent whole classes of security flaws. Not all, but things like "hardcoded passwords" can be avoided by outright banning of passwords in the protocol. For instance, replace that with a shared secret generation & exchange mechanism. (Passwords are shared secrets too, but their flaw lies in the generation. Hardcoded passwords are the ultimate generation bug)
In theory the encryption choices are limited to some degree because of bandwidth constraints. In practice none of that matters because the implementations will be half assed and broken regardless.
Ask any hardware guy that worked for a vendor, chances are he STILL remembers most of the back doors employers had in their products. Which security company backdoors do I still remember? Major ones.
Seriously, you want to solve "old security issues" that are only an issue because you attached some random device to the internet that has no business being attached to the internet.
The refrigerator, the thermostat, the kettle, the coffee maker, etc etc, these don't need connected to the internet. There is nothing about a thermostat that needs IP access to function.
As for your lights etc, there is this amazing thing called a light switch. Sure it involves you getting up off your ass to turn the things on and off, but suck it up princess.
I'm not being a Luddite either, some things work well enough being "dumb".
Perhaps because smart lightbulbs that refuse firmware updates and refrigerators with blue screens of death aren't enough fun on their own...
My TV's sound bar crashed last night and needed to be power cycled - and not via the power button, that was non-responsive, I had to yank the power cord. I have grown accustomed to rebooting my Roku and my TiVo and occassionally even my Plex server, but the sound bar?
Does anyone remember home cordless phones moving off the 902 - 928 MHz band to 2.4 GHz a decade or more ago, to escape all the garbage filling that chunk of spectrum?
.AH uses will help some, but they'll still be susceptible to all the other crap already operating on that band. And remember, FCC Part 15 means they have to put up with whatever's out there.
Amateur radio operators have that band (33cm) as a secondary allocation -- and can run up to 1500 Watts. Ha-Lo? Good-Bye! It's also primary to ISM (Industrial, Scientific, Medical) equipment. Still a lot of cordless phones, baby monitors, wireless audio and video extenders.
And that's the home of the "new" Ha-Lo devices... Oh, the strategies
If anything, they're hoping most of that crap has aged out of existence. There's still a lot out there. Oh, it's also ITU region 2 only -- the Americas. No sales in Europe, and no (legal anyway) sales in China, Japan, etc.

WTF?! It's not a soft drink. /RANT MODE (grin): When you semi-literate millennial fucks (not all of you mind you but certainly most of you) aren't getting the meaning of words complete wrong or "creatively reinventing" new meanings for words when perfectly adequate words already exist, you still can't seem to refrain from insisting on amping up the impact of your language with "high energy words." IT'S NOT A FUCKING ENERGY DRINK, EITHER! ;)
It's much more fun to consider the impending doom this protocol brings if you pronounce it to rhyme with "Hey Now" and imagine Jeffrey Tambor saying it.
"... make it attractive for use in applications such as connecting traffic lights and cameras in smart cities."
That would not be 'smart'.
One reason it could bring lesser security is the lower power part.
Security means more resources means more power means costly.
Yep. This is a thing and has happened before, many times.
In fact, it is quite common to have a decent high-level router for the home that has 2 networks, one with the best security you can get, and one set to low, basic security because a SHITLOAD of terrible and still pretty NEW devices with, at best, WEP.
