And so here is that sort
of balancing act, trying | 1,170.88 | 2.78 |
to figure out this balance between the
usability of the account, just how user | 1,173.66 | 3.87 |
friendly it is to access, versus
the security of that account. | 1,177.53 | 4.02 |
And finding that inflection point
is somewhat personal or somewhat | 1,181.55 | 3.09 |
corporate in policy, typically. | 1,184.64 | 2.28 |
Well, let me pause here and see
if there are any questions now | 1,186.92 | 3.87 |
on securing our accounts
via passwords alone. | 1,190.79 | 3.45 |
AUDIENCE: I was wondering. | 1,194.24 | 2.13 |
A couple of years ago, there
were devices, USB devices, | 1,196.37 | 3.24 |
with fingerprint recognition. | 1,199.61 | 2.58 |
How come that's not
more frequently used? | 1,202.19 | 3.48 |
Or are they too expensive or-- | 1,205.67 | 1.863 |
DAVID MALAN: A really
good question, and we'll | 1,207.533 | 1.917 |
come to this topic in a little
bit on biometrics more generally. | 1,209.45 | 3.42 |
But your intuition is pretty much right. | 1,212.87 | 1.68 |
It's expensive to have another device. | 1,214.55 | 1.957 |
And most consumers are not
going to bother wasting money | 1,216.507 | 2.333 |
on something just for them. | 1,218.84 | 1.23 |
Some companies might. | 1,220.07 | 1.17 |
But if they have a lot of employees,
that could get very costly. | 1,221.24 | 2.7 |
But you might be glad to know that
one of the topics we'll end on today | 1,223.94 | 3.36 |
is a new technology called
passkeys that actually leverages | 1,227.3 | 4.14 |
a device you most likely already have,
a phone, that might use your fingerprint | 1,231.44 | 4.65 |
or might use your face or
some other form of biometrics. | 1,236.09 | 2.91 |
That's becoming more common
nowadays, or soon will, | 1,239 | 3.24 |
even for your laptop and desktop which
will talk to that phone, in some form. | 1,242.24 | 5.53 |
How about one more question
here on securing accounts. | 1,247.77 | 3.95 |
AUDIENCE: My question is, why if
four-digits password is so unsafe, | 1,251.72 | 7.41 |
why is some program still using this
password not a website, like program? | 1,259.13 | 5.747 |
DAVID MALAN: Oh, really good question. | 1,264.877 | 1.583 |
Why are some programmers using this? | 1,266.46 | 1.82 |
So it's a trade off between
usability and security. | 1,268.28 | 3.24 |
If you are the programmer
designing the system, | 1,271.52 | 2.49 |
you presumably want users to
use the system and to come back | 1,274.01 | 3.45 |
and to keep using it. | 1,277.46 | 1.24 |
But if you make it too
hard for them to access | 1,278.7 | 2.87 |
that account, if you increase
the probability that they're | 1,281.57 | 2.67 |
going to constantly forget their
password, lose their password, | 1,284.24 | 2.91 |
they might just stop using your system
or your app or your website altogether. | 1,287.15 | 4.33 |
And so that's probably not a good thing. | 1,291.48 | 2.37 |
Other reasons might
include just unawareness | 1,293.85 | 2.36 |
or not having taken a class on
cybersecurity or not having really | 1,296.21 | 4.86 |
thought through the implications
of having such short passcodes. | 1,301.07 | 4.38 |
So nowadays is industry's
starting to nudge us | 1,305.45 | 2.837 |
in better and better directions. | 1,308.287 | 1.333 |
But we'll see today and
the rest of this class | 1,309.62 | 2.01 |
that there are still going to be a lot
of trade offs, again, between usability | 1,311.63 | 4.02 |
and security. | 1,315.65 | 1.08 |
So what can we do to defend ourselves
against these brute force attacks? | 1,316.73 | 3.33 |
Well, at least here in the
US, there's an organization | 1,320.06 | 2.25 |
called the National Institute
of Standards and Technology, | 1,322.31 | 2.88 |
Otherwise known as NIST, that
actually issues recommendations | 1,325.19 | 3.12 |
for how we as consumers or
companies or more generally, | 1,328.31 | 3.06 |
humans can go about securing
their accounts more effectively. | 1,331.37 | 3.15 |
And we thought we'd share just
some of these recommendations | 1,334.52 | 2.5 |
so that it informs not only your own
behavior as an individual citizen | 1,337.02 | 4.4 |
or consumer, but perhaps if
you're in a place of business | 1,341.42 | 2.97 |
where you can influence
your own company's policies, | 1,344.39 | 3.06 |
here are generally what are
considered best practices nowadays. | 1,347.45 | 3.73 |
So a quote from their
recommendations, "memorized secrets | 1,351.18 | 3.38 |
shall be at least eight
characters in length." | 1,354.56 | 3 |
So that at least corroborates
the quick math and the test | 1,357.56 | 2.94 |
that we ourselves just ran, that
only once we got up to, like, | 1,360.5 | 2.76 |
6 quadrillion possibilities
did it feel like it | 1,363.26 | 2.64 |
was going to take a very long time to
actually hack into someone's device. | 1,365.9 | 5.59 |
So consider that for your own
accounts, even on your phones. | 1,371.49 | 2.94 |
You might have to go
through a few menu options | 1,374.43 | 2.19 |
to upgrade from just four
digits to something more. | 1,376.62 | 3.27 |
But odds are you'll benefit from
this additional layer of security. | 1,379.89 | 4.38 |
This one's more of a
mouthful but helpful | 1,384.27 | 1.8 |
as well, "verifiers," so
the website or app that's | 1,386.07 | 3.72 |
verifying your input when you
authenticate with your username | 1,389.79 | 2.88 |
and password-- "verifiers should permit
subscriber-chosen memorized secrets | 1,392.67 | 4.77 |
of at least 64 characters in length. | 1,397.44 | 3.78 |
All printing ASCII characters
as well as the space characters | 1,401.22 | 3.3 |
should be acceptable
in memorized secrets. | 1,404.52 | 2.73 |
Unicode characters should
be accepted as well." | 1,407.25 | 2.86 |
Now, if you're not
yourself a computer person, | 1,410.11 | 2.33 |
there's a bit of jargon within this. | 1,412.44 | 1.71 |
But first of all, the takeaways are
that websites and applications should | 1,414.15 | 4.2 |
let you and me come
up with passwords that | 1,418.35 | 2.7 |
are actually as long as 64 characters. | 1,421.05 | 2.65 |
Now, that's pretty long, but
that's exactly the point, | 1,423.7 | 2.76 |
particularly as it's
gotten more difficult | 1,426.46 | 2.12 |
for you and I to remember
all of our passwords, | 1,428.58 | 2.83 |
to come up with very complex passwords. | 1,431.41 | 2.13 |
The reality is you and I
might very well be better off, | 1,433.54 | 3.78 |
on the whole, by just choosing an
easier-to-remember but much longer | 1,437.32 | 5.52 |
password, for instance, a sentence,
a quote, a phrase that you | 1,442.84 | 4.08 |
can more easily keep in your human
mind but that doesn't necessarily | 1,446.92 | 3.6 |
have a crazy amount of
punctuation or digits or letters, | 1,450.52 | 3.75 |
but at least is 64 characters in length. | 1,454.27 | 3.22 |
So even if an adversary
tries a dictionary attack, | 1,457.49 | 3.08 |
trying all possible English
words or some other language, | 1,460.57 | 2.71 |
even if they try a brute force attack,
it's going to take them way too long | 1,463.28 | 4.01 |
unless, of course, you do something
foolish like choose a 64-character | 1,467.29 | 4.02 |
passcode that's 000 or so forth. | 1,471.31 | 3.97 |
So you still want to be
original within that space. | 1,475.28 | 2.18 |
Now, more technically, this
recommendation is referring to ASCII. | 1,477.46 | 3.27 |
ASCII generally refers to US English
symbols on a US English keyboard, | 1,480.73 | 4.71 |
