Application (Layer 7) Firewalls - What they are and how they work

[@frijolito03]

I had no idea of this topic but after your video I have a first good view...thanks!!

[@LearnCantrill]

Glad it was helpful!

[@zahiddigital8301]

so if your ISP is using layer 7 firewall/deep packet inspection they can actually see the pictures/data you upload online even if you upload it on secure/HTTPS/encrypted sites such as facebook etc?

[@marcoavendano6593]

This was an outstanding explanation of a generally complex topic. Thank you.

[@LearnCantrill]

glad you like it :)

Great video ! I've a question, does the normal firewall which operate at the layer 5 is what we call a "stateful" firewall ? And the previous one (layer 3-4) a "stateless" firewall ?

[@LearnCantrill]

generally, yes.

[@DmitryTsarev]

Sorry for the necroposting, but I have just watched the video (a great one btw, you're very good at explaining and presenting!) and had the same question. So iptables is considered a level 5 firewall since it can track connections?

[@vlajov]

So great straightforward explanation! Looking forward for that future video about AWS employing app firewall, I guess its WAF service.

[@LearnCantrill]

Coming soon!

I noticed you're saying Haych for H, when you mention HTTP. This made me curious, and distracted me from the whole presentation, because I needed to look up who says that. In case anyone else was hit by that, it's some people in Ireland. I do appreciate your time put into this though, I did come back to watch the whole thing again.

[@LearnCantrill]

?? HTTP is an acronym.. H is pronounced Haych.. how else should i say it ? I'm not trying to be a jerk, but i genuinely don't understand how else i could say HTTP

[@n8ordi3]

the short answer most of the English speaking world pronounce "h" like aych, while some regions say haych.

U are an absolute G

[@amitb7611]

Does the application firewall inspect http response as well? Like WAF does?

[@LearnCantrill]

WAF is a layer 7 application firewall.
