Cybersecurity: Crash Course Computer Science #31 

thanks. been a while since I had a belly cramp laughing.

Thanks for making me read all that 😂

That was hilarious!

LMAO 🤣 crying😂😂😂😂😂😂🤣😅

RaymondHng that is everything

She stole a bunch of info about me I'm not proud of and some disgusting info I am proud of.

my face already include at least one symbol, at least one upper case letter and at least one number

Meanwhile in a plastic surgeon...

That's only if you used facial recognition (which is biometric) as the authentication mechanism. Just simply use long passwords.

Lololol

I laughed way more than I should have

dude thats racist

Seeing as this account is a satirical parody of the Nigerian prince email spams, it is not racist as it is just a reference to an actual occurrence. Even so, if there was no such thing as the Nigerian Prince email spam (which there still very much is lmao) the only adjective this account title uses is Nigerian, which describes ones place of origin or citizenship. If anything this account is nationalist, not racist. In conclusion, you have incorrectly analyzed the process and purpose I use to deliver humor in my comments and will not be receiving my horded millions of dollars.

Gabriel Agbese you got rekt dude

Anonymous Freak Yes, it sounds cheesy, and used to refer to something else...

How did you get your first job and what do you recommend learning for Cyber security

I love math.

Nice one XD

And assuming everyone has viewed it only once.

The thing is though, 2580 is a straight line down the keypad and we all know everyone hates straight lines

May the Schwartz be with you.

I do that all the time, I really stopped using English anymore lmao

I was going to make a comment about password length vs diversity of characters. Rainbow tables let me crack anything less than 14 characters really easy but anything more gets weird. One method I used to use was take a Chinese word, change the diphthongs to produce many different words and then string them all together in English. Easy for me to remember but really hard for a computer to guess. Like house horse mother. You go over the rainbow tables. Yep go look it up. It does not require a bunch of hard to remember special characters and numbers. One of my fun games at work is just repeating the same thing in as many languages as I can think of at the time. But sequential translations get weird. My favorite pattern is English, Spanish, German. Add slang and it gets weird really fast Long list, English, Spanish, (Taino if Puerto Rican), Portuguese, French, Romanian [short story later], German, Swedish, Dutch, Arabic (Burbur if they are Moroccan, like Ara means give me in Arabic but write or sign your name in Burbur), Uzbeki, Turkish, then Russian and then Polish. It makes sense in my head, don't judge me. I was telling a joke to a Puerto Rican woman last year and she stopped me in the intro telling me she knew Taino and knew what the word meant. It was a play on words. The only time that joke has failed me. Two points on Romanian. The first was a woman on her phone who just could not be bothered to get of her phone. So I said something to her in Russian. She was like why are you talking to me in Russian, and I was like because you are not paying attention to me in English and my Romanian is poor. The second was a Romanian women who would not get off her phone. So I got annoyed and started talking to her mother who was born in Romania. The mother then spent the next two minutes berating her daughter for not knowing how to pronounce words correctly in Romanian. Jewish mothers...

I will try that method.

Amy Jay good luck, Amy! Security+ was my first certification and it's a great starting point.

Some military jobs make us get the very in only 9 days of education with no experience. Often we have to test a couple times, but it's doable. The 501 version is gunna be killer though, so study up!

Briana Pierce haha. That sounds like learn to code in one weekend. Why even bother to study software engineering if you can learn that in one weekend or becoming a security consultant in 9 days. You gotta be kidding me.

I'm doin dat! I'm also getting Net+ and I already have my A+

Well, we manage to successfully do our jobs. Don't get me wrong, some people never make it through. But if you find the time we get amusing, you should realize that we take the exact same test as you, getthe exact same cert, and do our jobs effectively.

that ceramic cat collection doesn't buy itself XD

Almost. The last one is simply Authorization. Availability refers to the "ability to access data when we need it". The Parkerian hexad, although considered to be a more complete model, is not widely known as the CIA triad. It consists of: Confidentiality, Integrity, Availability, Possession, Authenticity, and Utility. Possession - physical dispostion of media on which data is stored in. Authenticity - data that can be properly attributed to the owner/creator. Utility - data that is useful depending on content and format.

leogomez4u skip it, read the books get hands on, grab your network+, ccna, security +, even an MCSA. A + knowledge is great but the cert isn’t worth the money.

Don't listen to them, A+ is your concrete to your house, network+, and Sec+, and etc are the walls and the roofs.

Actually Net+ is your concrete, walls and roof with Windows and doors while Security+ is your fence. The more experience with Security+ the higher the fence. A+ would be more like building the shed in the back. Nice to have but not important enough to live in or off (the cert).

_Mit_Whit _Gaming_ though it’s a really weird one because ones from the most disliked 3rd film Spy Kids 3d and the other is from Omniverse

Jepersprepur IKR?! 😂

_Mit_Whit _Gaming_ mmmhmmm

Now I'm sad I didn't get the Ben 10 reference

_Mit_Whit _Gaming_ The actual name of the black and red humanoid in 9:18 is actually "Malware", a villain from Ben 10: Omniverse, they might have used the character since Malware is a best symbol for the error

How’s it going so far

Updates, please don't drop out

"Lil' Bobby tables we call him...i hope you learned to sanitize your database inputs."

funny, go change your password now

That's actually a bad password.

Alternately (though I don't know how well this works in a federal system with different layers of elections), just use pencil and paper for voting like the Brits do.

Pen is better in this case since pencil writing can be erased.

if the topic is security... how is pen and paper more secure than Open source?

I was comparing pen to pencil.

my bad. I should had clarified I was refering to Andrew Farrell

Congrats! Follow your dream Dargon, Remember, The only thing you need is passion and curiosity!!!

Thijs Vandaele True!! Thank you.

You should post this kind of stuff on your RU-vid channel

Learn Kali Linux

Install gentoo hardened.

Even better, rely on someone else who knows what they are doing to do it for you. Even the experts get this stuff wrong from time to time and you're not an expert. Use a well known, heavily tested and actively updated library for anything security related. If you're doing anything other than something like library.storepassword(username, password) and library.startsession(username, password), you're probably doing something wrong.

Exactly right, though you'll need to know how things work at the layer of abstraction I described to know what to look for in a library. Don't roll crypto yourself except for fun & practice.

>or say you can't have a password longer than 16 characters Some companies do this for customer support reasons. They do a check on the string they're sent _prior_ to running the hash on it, so it can still be done securely. But longer passwords are more likely to be forgotten, so some large organisations might choose to restrict password length to reduce the burden on their customer support lines. If they can send you your password upon request though. Yeah, that's completely indefensible. They _might_ be able to email you your password immediately after you first set it (although that is a terrible idea because email is a terribly insecure protocol) without compromising database security, but at any other point they should not have access to your plaintext password.

@Jim Cullen you're right. Its a signal that they're storing the password, but not actually a guaruntee. But really what they should do to accomplish their goal is actively suggest passphrases. But people are often silly.

I wish more companies would encourage using password managers. Passphrases are okay, but they're no where near as good as an equally long pseudo-random password. And if they form sensible sentence structures (as opposed to being completely randomly chosen words), passphrases are even worse. Using good 2FA (*not* SMS-based 2FA) on more sites would also be nice.
