Cybersecurity: Crash Course Computer Science #31

Cybersecurity is a set of techniques to protect the secrecy, integrity, and availability of computer systems and data against threats. In today’s episode, we’re going to unpack these three goals and talk through some strategies we use like passwords, biometrics, and access privileges to keep our information as secure, but also as accessible as possible. From massive Denial of Service, or DDos attacks, to malware and brute force password cracking there are a lot of ways for hackers to gain access to your data, so we’ll also discuss some strategies like creating strong passwords, and using 2-factor authentication, to keep your information safe.

Check out Computerphile’s wonderful video on how to choose a password!

1:50 “that shows who your enemy is.” *shows a little girl on her computer*

A formidable foe.

I learned the same things in a 8 hour online course. Truly a Crash Course

Remember to change your face every 90 days to prevent hackers from getting into your account.

This video is bologna, if people don't click on random links in their emails, how will I ever give away my millions?

You're killing me with the "I'd take it ALL" ATM comment. I'm sitting here dying!

One thing I would like to see stressed is that two-factor authentication has to ask for two *different types* of authentication. Asking for a password _and_ a PIN is still only one-factor, because they are both things that you have remembered (or written down), so if someone has got hold of your password file they can enter one, two or twenty passwords correctly – asking for more than one doesn't stop them. This was something that online banking got very wrong for quite some time, although most banks seem to have got it sorted out now.

Just love going back from time to time to watch some of this amazing course episodes!

[RichIrving]

This is a great video. Explains the topic enough so that non-technical people understand the threats and how to mitigate them. Great job!

As a "cybersecurity"† professional, this is an excellent episode. Well written, well delivered. Just the right amount of detail for a "class, " while not being so over-simplified to be actually wrong. (I see that too often, newspaper articles, TV news segments that oversimplify to the point that what they say is wrong, not just "simplified.")

†I freaking *HATE* the word/prefix "cyber".

Fun fact: At 55, 000 views there's a 99.59% chance she guessed someone's pin.
Assuming that people PINs are evenly and randomly distributed.
1 - (9999/10000)^55000

Spot on with everything. I really enjoy the series! I have a pretty decent amount of experience with IT stuff, but I still manage to learn at least one new bit of info with every video. :D

Using this to prep myself for a Master's in Cybersecurity. This broke down everything way better than most of the material I have read.

It is a guilty pleasure every time Carrieanne says "doobalidoo".

[WoWDart]

I love this series. Thank you for all your hard work.

[zacharyedmond]

i work as a senior cybersec engineer in incident response and threat intelligence. love it!

[KeithMakank]

I work in security and I approve this message. Excellent video!

[illixx]

Carrie Anne keep it real. No access to ATMs or she'll take all of it xD

[Uejji]

That's amazing! I've got the same combination on my luggage!

[jess_tech]
