The Consumer Authentication Strength Maturity Model (CASMM) v5
If you know anything about internet security then you likely spend a lot of your time helping people improve their password hygiene.
People like moving up rankings, so let’s use that!
This post is an attempt to create an easy-to-use, visual model to help you have that conversation.
How to use this modelAll models are broken, but some are useful!
The idea here is for someone in the security community—or really any security-savvy user—to use this visual to help someone with poor password hygiene.
Here are a couple of ways you can do that.
Any improvement is good. Even one step matters.
Show Them Where They Are — The first way to use this model is to simply ask the user about their current behavior and show them where that ranks within these seven ranks. If you show them they’re down at rank 1 or 2, the combination of seeing how low they are in the chart and the color might convey some measure of concern.Show Them How to Move — Next, show them the various ways they can improve. As we discussed in this Twitter thread, keep in mind that you get the most benefit by moving from 4 and below to rank 5—although they still need to do the previous steps. The next big jump comes when moving from rank 7 or below to rank 8.Where one “should” be in this hierarchy depends on your threat model.
SummaryVisual maturity models can sometimes help people with their desire to improve.The highest security improvement one can get is by moving from any rank 4 and below—to Rank 5 (SMS-based 2FA).The second-best security improvement is moving from rank 5, 6, or 7—to Rank 8 (Passwordless).Try not to skip steps, i.e., it’s best to make the move to unique, quality passwords stored in a manager before you add 2FA.I hope this helps you!
NotesMar 30, 2021 — After more thinking and conversation with many in the security community, I reverted the numbering back to low-to-high instead of high-to-low. This is mostly because pretty much every other similar maturity model does the same. In other words, if there are 5 levels, level 5 is usually the best. Plus, having something be #1 implies that it can’t be improved, so if something better emerges it requires that the entire numbering system be reset rather than simply adding a new tier. Examples: CMMI, ISO, etc. Thanks to Ian L. for best making this point.Mar 30, 2021 — Another point to mention about “passwordless” is that if it were truly passwordless throughout the process it would likely be weaker than 2FA in most cases, but what we really mean by passwordless here is “from the perspective of the user at the moment of authenticating to something during the course of a day”. In other words, they’ve already fully authenticated to their OS, etc. to be able to use WebAuthN (for example) in the first place, so it’s not truly passwordless in most cases. But it is for the user experience at the time of a standard, daily authentication activity.Mar 29, 2021 — After much gnashing of teeth on Twitter, and many nice requests as well, I’ve added a higher tier for passwordless auth using technologies like WebAuthN and FIDO2. I also slightly tweaked the names of some of the boxes to make them shorter and clearer, and fixed an issue with Yubikey incorrectly being in Rank 2.Mar 26, 2021 — The response to this has been extraordinary, and a few people have already showed me translations into other languages! Evidently I was right in assuming that most security people have this conversation constantly, and appreciated having some sort of reference.Mar 25, 2021 — There are absolutely tangible differences between different “token” types. OTP is not the same as U2F is not the same as something that’s FIDO2 compliant. But for regular users I think it’s ok to combine them all into one that lives at the top of the model.Mar 24, 2021 — Thanks to Andrew R. Jamieson for making the suggestion to show what each rank is vulnerable to.Mar 24, 2021 — Someone mentioned that there are higher ranks of authentication out there, which I agree with, but this is specifically for everyday users.Mar 24, 2021 — We can pronounce the acronym as “Chasm”, as in, “Lets see how deep into the chasm you are…” 🙂Mar 25, 2021 — At the suggestion of someone on Twitter, I decided to invert the numeric scores for the levels, so 7 is worst and 1 is the best. People were saying progress makes more sense if it’s moving toward #1, and I think I agree.I know there’s debate about this, but even with all the recent (Spring 2021) attacks on SMS, I still consider SMS-based 2FA superior to password alone. My reasoning is simply that it requires more work for the attacker in most situations and prevents the most primitive form of credential stuffing—which is the most common type of authentication attack against accounts.Thanks to Troy Hunt, Anton Chuvakin, and Tim Dierks for spawning the idea for this.The Consumer Authentication Strength Maturity Model (CASMM)
This post is an attempt to create an easy-to-use security model for the average internet user. Basically, how secure is someone’s current behavior with respect to passwords and authentication, and how can they improve?

More on the COVID Lab-leak Theory— MIT Technology Review has an article out about how the lab-leak theory is refusing to die, and I think with good reason. The way I look at this is from a perspective of politics. Which narrative is extremely unpopular right now with mainstream media? A lab-leak theory that implicates China as a cause, that’s what. When there are significant numbers of experts saying something, and they’re being significantly squelched, I tend to amplify their likelihood of being right in my own mind. This doesn’t mean they are right. It just means they’re more likely to be right than is implied by their theory’s level of visibility. The other reason I’m willing to entertain this option is that similar things have happened many times before, in many countries, including the US. Again, I still feel very agnostic about the situation. It would not surprise me at all if we learn later that this was completely natural. But it shouldn’t surprise you either if it turns out to have come from a lab. Even if it did, this wouldn’t be a reason to hate China, or, obviously Chinese people. Again, this has happened many times in the US as well. It’s a problem that needs to be addressed everywhere this research is done. More

2 Reasons Active Will Replace Passive as the Future of HiFi
First, I’m fairly new to this whole audio thing, so what do I know. But I have spent a couple hundred hours studying the field over the last year, and I’ve done it with relatively non-biased eyes because I don’t have a dog in the fight.
Unjaded Observer Advantage
So you get the benefit of a perpetually curious super-nerd who hasn’t already spent tens of thousands of dollars on one solution or another. Which, as it turns out, counts for a lot.
First, what’s the debate? The debate is active vs. passive speakers. Or, to put it another way—the old-school way vs. the new and technology-powered way. A lot of it comes down to amplification and digital to audio conversion, and where and how those happen.
Many who get bit by the audio bug end up listening to systems instead of music.
With old-school systems going back decades, the DAC and the amps have been separate from the speakers. So the speaker is “passive” and must have power pushed into it to make sound. A newer (and rising in popularity) method of doing this is to have the amps and the DACs right in the speakers themselves, so all you need to do is power them and send them a digital signal.
The old-school audio community and wine communities have a lot in common.
Basically, the old-school types hate the new stuff. They think it’s a Satanic Dungheap. And they’re happy to tell you as much. They think it’s all about pairing this with that, swapping stuff in and out, trying different cables, and taking a wine connoisseur approach to things. Adjust, taste. Enjoy. Discuss. Etc.
What the traditional audiophiles won’t tell you is that they’re addicted to upgrades.
Which would be totally fine! But there’s a trap. The trap is that much of this audiophile community is over-indexed on the chase. For far too many of them, it’s not about the music. Or even the gear! It’s about changing the gear. It’s about looking for the next big upgrade to get that one extra squeeze of happiness from your system. Until you hear someone else’s system and you’re thrown into an existential crisis and you have to sell everything and start over from scratch.
Perpetual Optimization is a common proxy for meaning.
And don’t get me wrong, I’m actually super attracted to this. This pursuit game is a common one, especially for men in their 20’s and 50’s. The whole idea of optimizing a system is highly seductive. I get it. So I’m not hating here.
Now, enter the newcomers—many of which you can find over here at Audio Science Review. First, they tend to be Objectivists, meaning they value measurement and blind testing far more than the old-schoolers who often think their ears are the only measurement they need.
But most importantly for today’s topic, they believe in the active way of doing audio in a room. And I think they might have a point. Specifically, here are the two reasons I think active will win over time.
Pairings Are Everything: If you hang around in any audiophile forums or channels you’ll find everyone talking about how this amp pairs with this DAC and this speaker. Ad infinitum. It’s one of the primary topics, and this is precisely what active systems do so well because all three were designed to work perfectly together.The Room Matters More Than Most Know: At the very high-end of audio you start to realize that a $10,000 system in a great or treated space can sound like a $50,000 system. And a $200,000 system in a bad room can sound like a $50,000 system. The room matters. A lot. And these new active systems aren’t just shooting out air: they’re using the latest technology to control how the speakers emit sound, they’re using technology to adjust their sound with EQ, and—most importantly—they’re using measurement techniques to optimize the sound of the entire system within a given listening space.These are huge. Again, in the traditional/passive world these account for a massive percentage of your results. If you have a bad pairing, or a bad room, you can end up with a crap system—even if you spent a lot of money.
Active systems technology will improve far faster than the quality of traditional components because the latter is so much older and more established.
With active systems that are perfectly paired, work synergistically together between the highs, mids, and lows, and adjust their sound based on the space they’re in, you’re getting an automatic boost in overall experience that people would kill for in the passive world. All because of new technology.
Putting love into anything can be fun.
This starts to look like a battle between the old Mustang 5.0 that’s had $50,000 of love put into it over the last 20 years, vs. the Tesla Model 3 that destroys it off the line every time.
Now that analogy only works for a specific measurement, which is acceleration off the line. But that happens to be one of the most traditionally coveted metrics in car-loving history. And my argument is that this passive vs. active situation is very similar when it comes to overall sound quality.
Get Off My Lawn™
You’ll still have people at the audio and car shows showing off their super expensive old-style stuff. And pouring tons of love into their equipment—which is wonderful—but they’re going to look the other way when some 20-year-old drives through in a Tesla looking for a race. Or showing off a full Genelec active system where the monitors, woofers, and subs all work together to do exactly the right thing at the right time for the room that they’re in.
That’s the audio equivalent of zero to sixty in 2.9 seconds.
And here’s the crazy part—the active world can keep getting better! There is plenty of room to grow in the fast-moving world of technology when you fully control the amps, the DACs, the speaker designs, and you have all that adjusting dynamically to the room.
Anyway, those are the two main reasons I think active will win:

Chart Scale Types
When Steven Few is confused about something that means I probably am as well. He also writes blog posts for the same reason I do—which is to clarify confusion in his own mind.
I’ll also capture a few he didn’t talk about.
In this post about ordinals, he talks about how they’re often used incorrectly. But most important to me, he gives a number of definitions that I wanted to capture here.
Here are the main types of scales used in showing data on a chart.
Nominal Scale: Only the selection name matters, not any particular order. Example: “What’s your favorite streaming service? NETFLIX, Disney+, Hulu, or Other?”Ordinal Scale: Only the order matters, but you can’t tell the relative difference between the items. Example: “What is the most prestigious college according to Forbes? Answer: Harvard, Stanford, Princeton, etc.”It’s often bad to assign quantitative values to items in a Likert Scale.
Using scales incorrectly can cause confusion in those consuming your data.
Interval Scale: Subdivides a range of quantitative values into equal intervals. Example: “0, 10, 20, 30, 40, 50”Likert Scale: Allows one to respond to a question with ordered responses, but where the answer is not quantitative. Example: “Do you drink Heavily, Moderately, Seldom, Never?”Logarithmic Scale: A logarithmic scale is where each marker corresponds to an equal logarithmic distance. Example: “One, Ten, One Hundred, One Thousand, Ten Thousand, One Million”A log is an exponent.
Charles Wheelan, Naked Statistics
In a Base 10 log scale, each number would be 10x the previous number.
Ratio Scale: An ordinal scale that also gives you quantitative data. Example: “Over 6 Feet, Less than 6 Feet but Over 5 Feet, Below 5 Feet”The biggest takeaway for these is that using them incorrectly can totally change the meaning of the data you’re trying to display. Or, more accurately, it can lead you and others to draw conclusions that they shouldn’t.
Especially if there are big differences in the values.
If your quantitative scales are wrong, or if you assign numbers to Likert Scales, you can end up painting a picture that doesn’t match reality. But because your chart looks nice people will believe it.
It’s like Lying With Statistics, except on accident.
Learn the scale types so you can avoid this.
