[@TheBadFred]

As soon as you rely on someones else's code you most likely get vulnerabilities. The only way around that is to write everything yourself in Assembler, then you will have only your own vulnerabilities.

[@Fireship]

You can use other people's bugs, or create your own from scratch.

[@TheBadFred]

@@Fireship Even if you create completely vulnerability free code there are still hardware vulnerabilities like Meltdown and Spectre.

[@luizvaz]

Until your code meet someone that knows ASM and debug your code. Rewrite your masterpiece and deploy a patch!

[@McDonnerbogen]

You better start writing your assembly code or you will never get done ;)

[@lucasgazzola]

Totally agree

[@AZisk]

The best security videos are scary - nice work on this one! For those folks dealing with mobile apps, whether built with JavaScript or not, there are a bunch of other security considerations to keep an eye on. The point is that you're never truly safe. As long as you have something valuable that could be hacked, someone out there will keep trying. You have to dedicate the time and resource to always stay on top of your security, it's not a set-it-and-forget-it thing.

as a security researchet i can validate that we need a ton of awareness to impart to our devs. I've seen some of the scariest vulnerable code making it to production.

[@BattyBest]

The actual way to protect from ddos attacks is by blocking requests from ips that constantly send a bunch of requests, and then ask them to do a human verificiation. Scaling gets reeeeeeealy costly.

[@arnoldas9730]

So if you block ip, how would your server respond with human verification?

[@BattyBest]

@@arnoldas9730 Blocking an IP is a server-side operation, and can be reverted immediately. What I am talking about is this: - Attacker sends a lot of requests - Server notices, and sends a verification - Verification is not received, any more packets from that ip are blocked - Another IP, this one not an attacker, sends a lot of requests - Server notices, and sends a verification - The new IP responds with verification - Server allows higher than normal requests temporarily - If this IP continually sends a large amount of packets, it may be throttled.

[@HuyTran-wv3tz]

that is the basic way to solve dos, NOT ddos

[@g-luu]

yesss...... longer videos. Great job as always.

[@osmantoplica8912]

Last tip could be a very very expensive one. Don't "fix" DDOS by scaling 😄

[@OmerMD]

Can you explain the reasoning for it?

[@WACdeG]

@@OmerMD That could lead to enormous costs.

[@madhououinkyoma]

Yeah, he definitely didn't quite go into it. But I guess the main point there was that scaling can be the needed solution if your service just cannot go down. You can set an upper bound on how high your services will scale. And of course, you should do other things as well and not just rely on scaling.

[@guillemgarcia3630]

concise and precise, I loved it!

[@syntaxerorr]

lol oh that hangover clip was perfect!

[@andrij.demianczuk]

This is amazing. Thank you for putting this together. Vulnerabilities are endemic to orgs that rush production. My heart always hurts when I hear folks complaining about IAM roles and policies (regardless of hyper scaler). They’re just so darn important to good cloud hygiene.

[@markarca6360]

The principle of least privilege is implemented in Microsoft Windows' UAC (User Account Control), that is included in Windows since Windows Vista. This is also implemented in UNIX and Linux as the sudo (do as superuser) command.

[@aleksandarstevanovic5854]

Kevin Mitnick wrote in his book "Security is an illusion, you will put alarm on a door and feel safe, but what if burglar use window?". Modern frameworks are mostly safe against old methods od exploit unless you overengineer something, but they are not perfect, along the way they made anorher vulnerabilities which we will be talking about in the future

The CIA part came a little short. You do a great job compressing so much knowledge in these short videos. In some cases a shortcut might be falsy though. You're not done with integrity because an intruder can't just manipulate data. You also must know if a manipulation took place in case of an breach otherwise the first point is... pointless.

Is there any tips for hiding the API key when I use a API on a program I’m sharing with others. I’m on a forum where we share script and I sometime share my scripts. So how can I hide the API key I use? I know obfuscation can’t work as the obfuscation can get constant dumped.

Pro tip: never use API keys as authentication. That’s not their intended purpose. They are inherently unsafe.

About lest priviledge: A few years ago, a bank in Canada (Desjardins) had a huge data leak of 100s of 1000s of their customers, some guy that tried to pawn of all that data into the dark web. Turns out the guy was from marketing, pissed about his job and for some reason had access to whole bunch of things he really didn't need to if all he needed to do in life was like know what % of customers both have a mortgage and car loan with them.

[@valentynkhaman7688]

Good video!

[@blackwolf542]

It's the predator/prey thing. The prey evolves to better avoid the hunter and survive, the predator evolves to better hunt it's prey and the cycle continues. Being aware of bugs and vulnerabilities and constantly evolving to identify and patch them is the only real way to keep it as secure as possible, it is a constant evolution as hackers are always evolving themselves.

DDOS Attack looks very interesting, how do they prevent it if they dont have the compute power?

Google Cloud Armor and Cloudflare both serve as good protection against DDoS attacks, but also making your own web applications detect DDoS attacks and automatically deny is a (not that) decent way of protection as it'll at least reduce time spent processing requests since they're just rejected. Sure, it's not a 100% foolproof method, but you could cut the cost of the attack way down with this

At 5:12 ish, can someone explain to me why setting the API key as an environment variable is safer than hardcoding it? Wouldn't the environment variable also get published on GitHub?

[@hamzajps]

env files are usually put in .gitignore file, hence they are not pushed to remote origin like github. They just remains on your local machine

[@JarenKurkoff]

Well, unless you specifically write a script to dump all of your environment variables *before* pushing to a Git repository, then its because environment variables are stored within your *shell*, not your project, so something like Bash, sh, ksh, csh, and many other UNIX shells.

[@madhououinkyoma]

Environment variables stay on your local computer/server. There is no "file" to be published on Github so that's usually a safe place for information like this.
